Zrost błon śluzowych
Epidemiologia
Zrost błon śluzowych (labial fusion) to schorzenie polegające na częściowym lub całkowitym sklejeniu warg sromowych mniejszych lub większych, prowadzącym do niedrożności ujścia pochwy i/lub cewki moczowej. Występuje najczęściej u dziewczynek przed okresem dojrzewania, z częstością około 0,6-5%, ze szczytem zachorowań w wieku 13-23 miesięcy (do 3,3%). U noworodków jest praktycznie nieobecny, a u kobiet w wieku rozrodczym bardzo rzadki ze względu na prawidłowy poziom estrogenów. U kobiet po menopauzie zrosty występują częściej, szacuje się, że dotyczą 40-54% pacjentek z zespołem genitalno-moczowym związanym z menopauzą (GSM). Główne czynniki ryzyka to niedobór estrogenów, stany zapalne, urazy mechaniczne, nawracające infekcje dróg moczowych, nieodpowiednia higiena oraz dermatozy sromu (np. liszaj twardzinowy). Diagnostyka opiera się głównie na badaniu fizykalnym, a w wybranych przypadkach wykonuje się badanie ogólne moczu, cystouretrografię mikcyjną lub badanie endoskopowe.

Epidemiologia zrostu błon śluzowych
Zrost błon śluzowych (labial fusion) to schorzenie charakteryzujące się częściowym lub całkowitym sklejeniem warg sromowych mniejszych lub większych powodującym częściową lub całkowitą niedrożność ujścia pochwy i/lub cewki moczowej1. Częstość występowania tego schorzenia różni się w zależności od grupy wiekowej oraz badanej populacji.2
Częstotliwość występowania u dzieci
Zrost błon śluzowych jest stosunkowo częstym schorzeniem wśród dziewczynek przed okresem dojrzewania. Według różnych źródeł dotyka on około 0,6-5% prepubertalnych dziewczynek34. Dokładniejsze badania epidemiologiczne wskazują na wskaźnik zachorowalności na poziomie około 1,8%52. W szczytowym okresie występowania, czyli u dziewczynek w wieku 13-23 miesięcy, częstość wzrasta nawet do 3,3%26.
Warto zauważyć, że jedno systematyczne badanie dotyczące oceny narządów płciowych u dziewczynek przed okresem dojrzewania wykazało znacznie wyższą częstość występowania – nawet 38,9%, jednak włączało ono również bardzo małe zrosty (2 mm lub mniejsze) wykrywane wyłącznie przy użyciu kolposkopu6.
Należy podkreślić, że zrost błon śluzowych prawie nigdy nie występuje u noworodków75. Badanie obejmujące ponad 9000 noworodków płci żeńskiej nie wykazało ani jednego przypadku tego schorzenia w okresie noworodkowym5. Typowo rozwija się on w wieku około 1-2 lat78.
Występowanie u kobiet w wieku rozrodczym i pomenopauzalnym
Zrost błon śluzowych jest niezwykle rzadki u kobiet w wieku rozrodczym910. Jest to uwarunkowane prawidłowym poziomem estrogenów u kobiet w tym okresie życia11. Pojedyncze przypadki opisywane w literaturze medycznej uznawane są za wyjątkowe i wymagające dokładnego wyjaśnienia przyczyny12.
Schorzenie to występuje natomiast częściej u kobiet po menopauzie, choć dokładna częstość występowania w tej grupie wiekowej nie jest znana113. Szacuje się, że problem ten może dotyczyć 40-54% kobiet z zespołem genitalno-moczowym związanym z menopauzą (GSM), który często pozostaje niezdiagnozowany lub nieleczony11.
Czynniki ryzyka i predyspozycje
Nie zaobserwowano wyraźnych predyspozycji rasowych w występowaniu zrostu błon śluzowych5. Głównym czynnikiem ryzyka jest niski poziom estrogenów, co tłumaczy częstsze występowanie schorzenia u dziewczynek przed okresem dojrzewania oraz u kobiet po menopauzie1415.
Do dodatkowych czynników predysponujących należą316:
- Stany zapalne okolicy sromu i pochwy (m.in. nawracające zapalenie sromu i pochwy)
- Urazy mechaniczne okolicy genitalnej
- Nawracające infekcje dróg moczowych
- Nieodpowiednia higiena okolicy genitalnej
- Dermatozy sromu (np. liszaj twardzinowy, liszaj płaski)
U kobiet po menopauzie zrost błon śluzowych często występuje jako triada: niedobór estrogenów, zapalne choroby skóry oraz brak aktywności seksualnej1.
Nadzór i monitoring
Objawy kliniczne i diagnostyka
Zrost błon śluzowych jest w większości przypadków schorzeniem bezobjawowym, zwłaszcza u dzieci187. Diagnoza stawiana jest najczęściej przypadkowo podczas rutynowego badania lekarskiego1920. Podstawą rozpoznania jest badanie fizykalne okolicy genitalnej16.
U części pacjentek mogą jednak występować objawy kliniczne, takie jak421:
- Zaburzenia mikcji (zmieniony strumień moczu, moczenie popuszczające po mikcji)
- Zatrzymanie moczu (w przypadku całkowitego zrostu)
- Nawracające infekcje dróg moczowych
- Świąd i podrażnienie okolicy sromu
- Zapalenie sromu i pochwy
- Dyskomfort podczas mikcji
- Zatrzymanie wydzieliny pochwowej (w przypadku całkowitego zrostu)
U kobiet po menopauzie i dziewcząt w okresie pokwitania z całkowitym zrostem może dochodzić do zatrzymania krwi miesiączkowej za zrośniętymi wargami, co stanowi stan nagły wymagający pilnej interwencji medycznej21.
Diagnostyka zrostu błon śluzowych zazwyczaj nie wymaga wykonywania specjalistycznych badań20. W wybranych przypadkach, szczególnie przy podejrzeniu infekcji dróg moczowych, można wykonać badanie ogólne moczu20. W niektórych rzadkich przypadkach u kobiet po menopauzie, zwłaszcza przy nieprawidłowych wynikach badań obrazowych miednicy, może być konieczne przeprowadzenie badania endoskopowego w celu dokładnej oceny anatomicznej struktur2324.
Przebieg naturalny i wskazania do leczenia
Zrost błon śluzowych u dzieci ma zazwyczaj łagodny przebieg i dobrą prognozę25. W większości przypadków następuje samoistne ustąpienie objawów w okresie dojrzewania, gdy wzrasta poziom estrogenów726. Schorzenie to nie ma wpływu na przyszłe zdrowie reprodukcyjne i płodność2728.
Wskazania do leczenia zrostu błon śluzowych obejmują2711:
- Całkowity zrost błon śluzowych powodujący zatrzymanie moczu
- Nawracające infekcje dróg moczowych związane ze zrostem
- Znaczny dyskomfort i dolegliwości bólowe
- Zatrzymanie wydzielin pochwy lub krwi miesiączkowej
W większości przypadków, szczególnie u dzieci bez objawów, zaleca się postawę wyczekującą i regularne monitorowanie stanu pacjentki3031.
Monitorowanie nawrotów
Nawroty zrostu błon śluzowych są stosunkowo częste, niezależnie od zastosowanej metody leczenia14. Wskaźniki nawrotów po leczeniu zachowawczym lub chirurgicznym wahają się w przedziale 11-14%1432, choć niektóre badania wykazują znacznie wyższe wskaźniki nawrotów – nawet do 41%33 czy 55%34.
Ryzyko nawrotu zmniejsza się wraz z wiekiem i zwiększoną produkcją endogennych estrogenów3. Czynniki przyczyniające się do nawrotów obejmują317:
- Niedostateczną higienę okolicy genitalnej
- Nawracające zapalenia sromu i pochwy
- Dermatozy sromu
- Brak aktywności seksualnej (u kobiet po menopauzie)
Pacjentki po leczeniu chirurgicznym zrostu błon śluzowych wymagają regularnych kontroli. W przypadku kobiet po menopauzie, mimo stosowania miejscowej terapii estrogenowej, mogą występować nawroty, co podkreśla znaczenie długoterminowej obserwacji i indywidualizacji planów leczenia36.
Znaczenie kliniczne i wpływ na jakość życia
Zrost błon śluzowych, choć zazwyczaj bezobjawowy u dzieci, może mieć istotny wpływ na jakość życia, szczególnie u kobiet po menopauzie i w przypadkach objawowych37. Schorzenie to może powodować dyskomfort podczas codziennych aktywności, problemy z higieną intymną oraz prowadzić do zaburzeń psychologicznych związanych z postrzeganiem własnego ciała37.
U kobiet w wieku rozrodczym i po menopauzie zrost błon śluzowych może prowadzić do937:
- Dyspareunii (bolesnego stosunku płciowego)
- Zaburzeń funkcji seksualnych
- Obniżenia jakości życia seksualnego
- Problemów z mikcją i nawracających infekcji dróg moczowych
- Dyskomfortu psychicznego i problemów emocjonalnych
Wczesna diagnoza i leczenie zrostu błon śluzowych, szczególnie w przypadkach związanych z dermatozami (takimi jak liszaj twardzinowy), mogą zapobiec postępowi choroby i rozwojowi powikłań17. Odpowiednie leczenie i edukacja pacjentek mogą znacząco poprawić jakość ich życia37.
Metody nadzoru i obserwacji
Monitorowanie dzieci z zrostem błon śluzowych
U większości dzieci ze zrostem błon śluzowych zaleca się postawę wyczekującą i regularne wizyty kontrolne u lekarza pediatry3038. Nie ma konieczności kierowania do specjalisty, chyba że występują objawy kliniczne lub powikłania31.
Podczas wizyt kontrolnych lekarz powinien ocenić730:
- Stopień zrostu błon śluzowych
- Obecność ewentualnych objawów klinicznych
- Prawidłowość mikcji
- Stan higieniczny okolicy genitalnej
Rodzice powinni zostać poinformowani o łagodnym charakterze schorzenia, jego naturalnym przebiegu oraz braku wpływu na przyszłą płodność i funkcje seksualne dziecka33. Należy również wyjaśnić, że aktywne leczenie zazwyczaj nie jest konieczne i może wiązać się z dyskomfortem oraz ryzykiem nawrotu31.
Postępowanie u kobiet po menopauzie
Kobiety po menopauzie ze zrostem błon śluzowych wymagają bardziej aktywnego podejścia ze względu na większe ryzyko objawów klinicznych i powikłań11. W przypadku kobiet po menopauzie zaleca się1315:
- Kompleksową ocenę ginekologiczną
- Wczesne rozpoczęcie leczenia, szczególnie w przypadku objawów klinicznych
- Wykluczenie współistniejących dermatoz sromu (np. liszaja twardzinowego)
- Rozważenie miejscowej terapii estrogenowej, nawet po leczeniu chirurgicznym
- Regularne wizyty kontrolne w celu monitorowania nawrotów
U kobiet z całkowitym zrostem błon śluzowych powodującym zatrzymanie moczu lub wydzielin pochwowych konieczna jest pilna interwencja medyczna2111.
Badania diagnostyczne i obrazowe
W większości przypadków zrost błon śluzowych jest diagnozowany na podstawie badania fizykalnego, bez konieczności wykonywania dodatkowych badań diagnostycznych20. Jednak w wybranych przypadkach, szczególnie przy podejrzeniu powikłań, mogą być wskazane następujące badania2040:
- Badanie ogólne moczu – w przypadku podejrzenia infekcji dróg moczowych
- Cystouretrografia mikcyjna – może wykazać gromadzenie się kontrastu powyżej zrośniętych warg sromowych oraz znaczny refluks do pochwy
- Badanie endoskopowe – w wybranych przypadkach u kobiet po menopauzie w celu dokładnej oceny anatomicznej struktur
W przypadku podejrzenia współistniejących dermatoz sromu, takich jak liszaj twardzinowy, może być konieczne wykonanie biopsji w celu potwierdzenia rozpoznania17.
Znaczenie edukacji pacjentek i ich rodzin
Edukacja pacjentek i ich rodzin odgrywa kluczową rolę w postępowaniu ze zrostem błon śluzowych33. Należy przekazać następujące informacje728:
- Zrost błon śluzowych jest częstym schorzeniem u dziewczynek przed okresem dojrzewania
- W większości przypadków nie powoduje objawów i nie wymaga leczenia
- Samoistnie ustępuje wraz z dojrzewaniem płciowym
- Nie ma wpływu na przyszłą płodność i funkcje seksualne
- Aktywne leczenie może powodować dyskomfort i zwiększać ryzyko nawrotu
- Właściwa higiena okolicy genitalnej może pomóc zapobiec nawrotom
W przypadku kobiet po menopauzie ważne jest również wyjaśnienie związku między niedoborem estrogenów a zrostem błon śluzowych oraz możliwości leczenia1122.
Odpowiednie informowanie pacjentek i ich rodzin pomaga zmniejszyć niepokój związany ze schorzeniem oraz zwiększa świadomość na temat znaczenia regularnych kontroli lekarskich4241.

- #1 Labial Adhesionshttps://ej-med.org/index.php/ejmed/article/view/1917
Labial adhesion is characterized by partial or complete fusion of labia minora or labia majora. […] The incidence of labial adhesions is about 0.61.4% in children, but the incidence in elderly is unknown, and only a few case reports are documented in postmenopausal women. […] The exact cause of labial fusion remains unknown but It occurs mostly due to estrogen deficiency both in prepubertal girls and menopausal women, and is commonly associated with lack of sexual activity and inflammatory skin disorder. […] Labial adhesion in menopausal women is usually triad of estrogen deficiency, inflammatory skin disorders, lack of sexual activity.
- #2 Labial fusion – Wikipediahttps://en.wikipedia.org/wiki/Labial_fusion
Labial fusion is not uncommon in infants and young girls. It is most common in infants between the ages of 13 and 23 months, and has an incidence of 3.3% in this age group. It is estimated that labial fusion occurs in 1.8% of all prepubertal girls. It is rare in adult women, particularly in reproductive age, but is occasionally found in postpartum and postmenopausal women.

Labial fusion (LF) is frequently an asymptomatic condition and hypoestrogenism plays an important role in the pathopysiology. […] The incidence of LF in girls in childhood is stated as 0.6-5% in different sources. […] According to an epidemiological study conducted in the USA, the age distribution in which it is observed is given as 6-24 months. […] The risk of recurrence decreases with increasing age and increased endogenous estrogen production. Factors contributing to recurrence include poor genital hygiene, recurrent vulvovaginitis, and vulvar dermatoses.
- #4 Labial adhesion – diagnostics and treatment | Tidsskrift for Den norske legeforeninghttps://tidsskriftet.no/en/2017/01/original-article/labial-adhesion-diagnostics-and-treatment
It is estimated in the literature as a whole that labial adhesion occurs in 0.6 to 3.3 % of girls of prepubertal age. […] Although most children with labial adhesion are asymptomatic, the condition has been associated with a number of complaints, such as urethritis, itching, vaginitis, altered urinary flow, asymptomatic bacteriuria, urinary tract infection, urinary retention, split urinary stream, post-void dribble as a result of accumulation of urine in the adhesion, and enuresis. […] Treatment is either pharmacological or surgical. Pharmacological treatment consists of oestrogen cream or glucocorticoid cream. Surgical treatment involves techniques such as manual separation, or the use of a double-end probe or tenaculum following anaesthesia with Emla cream. […] Our evaluation of patient records from St. Olavs Hospital revealed that, in more than half of cases, complete opening was not achieved with pharmacological therapy, surgery or a combination of the two.
- #5 Labial Adhesions: Practice Essentials, Pathophysiology and Etiology, Epidemiologyhttps://emedicine.medscape.com/article/953412-overview
Labial adhesions are a common disorder in prepubertal females, who are hypoestrogenic. This disorder is usually asymptomatic and is often first noticed by parents or during a routine physical examination. Labial adhesions occur most frequently between the ages of 3 months and 6 years. […] A prospective study of more than 1900 girls assessed through a pediatric outpatient clinic reported a 1.8% incidence of labial adhesions, whereas a review of more than 9000 female infants found no cases of neonatal labial adhesions. The incidence of labial adhesions worldwide is unknown but presumably is similar to the US incidence. […] Labial adhesions are, by definition, a disorder of females and occur most often in infants and girls aged 3 months to 6 years, with a peak incidence around the age of 13-23 months. They have not been reported in the newborn period. If left untreated, labial adhesions usually spontaneously resolve at puberty as a consequence of increased estrogen levels. They also occur in older women, albeit rarely. […] No strong evidence supports a racial predilection.

Labial agglutination in younger prepubertal girls is rather common, but it is rarely described in dermatological textbooks. […] The estimated labial adhesion rate in girls is about 1.8%, with a peak incidence of 3.3% at 1323 months of age. […] However, in a single study systematically studying genital findings in prepubertal girls, a prevalence as great as 38.9% has been found, including very small adhesions of 2 mm or less detected only through the colposcope. […] The cause of labial agglutination appears to a mild inflammatory condition in a child with a thin layer of labial epithelial cells secondary to a low oestrogen level. […] If the labial agglutination is asymptomatic it is recommended to wait for spontaneous resolution, which will often happen when the oestrogen level rises at the onset of puberty.
- #7 Labial fusionhttps://www.rch.org.au/kidsinfo/fact_sheets/Labial_fusion/?hc_location=ufi
Labial fusion is a condition where the two flaps of skin on either side of the opening to the vagina (the labia minora) are joined together. It is also sometimes called labial adhesion or agglutination. Labial fusion is a common condition, and there is no need for concern in most cases. […] The fusion (join) will usually separate by itself by the time your child reaches puberty. Treatment is not usually needed or recommended because it can cause your child pain and anxiety. There is also a risk that the fusion will return if any treatment is carried out. […] The exact cause of labial fusion is not known, but sometimes it occurs after an inflammation of the labial area (e.g. after a simple infection such as vulvovaginitis, or after mild trauma to the area). […] Labial fusion is almost never present at birth, but usually develops around one to two years of age. If your child has labial fusion, instead of two separate labia, you will be able to see the labia joined together. There are not usually any other symptoms.
- #8 Labial Fusion In Children | KidsHealth New Zealand’s Trusted Voice On Children’s Healthhttps://www.kidshealth.org.nz/vulval-conditions/labial-fusion-in-children
Labial fusion is common in tamariki (children). […] In most cases, labial fusion needs no treatment. […] Labial fusion resolves as your child grows. […] Labial fusion usually develops when a child is around 1 to 2 years of age. […] Treatment is not needed for most cases of labial fusion in children. […] Labial fusion is not linked to any other medical conditions.
- #9 Labial Agglutination in a Reproductive Age Womanhttps://clinmedjournals.org/articles/ogcr/obstetrics-and-gynaecology-cases-reviews-ogcr-9-231.php?jid=ogcr
A 25-year-old nulligravid was consulted due to inability to have sexual intercourse accompanied by chronic urinary hesitancy, dribbling, and dysmenorrhea. […] This paper describes a stepwise management of a reproductive-age woman with complete labial fusion. Treatment goals include etiological determination, anatomic correction, restoration of normal sexual function, improvement of genitourinary function, and improved quality of life. […] Labial fusion during reproductive years should be carefully investigated as this is exceedingly rare and unexpected in reproductive-age women with normal hypothalamic pituitary ovarian (HPO) function. Issues of underlying predisposing factors need to be addressed and are necessary to prevent recurrence. […] Labial agglutination is extremely rare in reproductive-age women.
- #10 Labial Agglutination in a Reproductive Age Womanhttps://clinmedjournals.org/articles/ogcr/obstetrics-and-gynaecology-cases-reviews-ogcr-9-231.php?jid=ogcr
Labial adhesion in reproductive age is unexpected and extremely rare due to adequate levels of estrogen. Therefore, in the reproductive-age group, the integrity of their HPO axis should be evaluated. […] Recurrent urinary tract infection is more commonly a result, rather than a cause of labial adhesions. However, the temporality of events and the patientâs lack of any other predisposing factors point to an association with her urinary symptoms. […] There are different treatments for labial adhesions in pre-pubertal and postmenopausal women. It can be managed conservatively through topical estrogen treatment with or without manual separation of labia or surgery. However, in reproductive-age women with normal HPO function, surgery is the logical treatment choice. […] Labial fusion during reproductive years should be carefully investigated as this is exceedingly rare and unexpected in reproductive-age women with normal hypothalamic pituitary ovarian (HPO) function. Issues of underlying predisposing factors need to be addressed and are necessary to prevent recurrence.
- #11https://journals.lww.com/jomh/fulltext/2024/15030/labial_fusion_in_a_postmenopausal_woman_presenting.16.aspx
Genitourinary syndrome of menopause refers to the collection of signs and symptoms associated with decrease in estrogen and other sex steroids involving changes in labia majora/minora, clitoris, vestibule/introitus, vagina, urethra, and bladder. […] Labial fusion refers to the complete or partial fusion of labia minora in the midline due to adhesions. […] Approximately 40%54% of women experience a genitourinary syndrome of menopause (GSM), which is often undiagnosed/not treated. […] In the postmenopausal stage, low estrogen levels render the genital area more prone to irritation and inflammation leading to labial fusion. […] Complete labial fusion is a rare presentation of GSM. […] Management protocol at the early stage includes topical estrogen therapy and treatment of predisposing factors, whereas refractory cases need surgical separation.
- #12 An unusual clinical presentation of labial fusion in post pubertal period – Document – Gale OneFile: Health and Medicinehttps://go.gale.com/ps/i.do?id=GALE%7CA536389218&sid=googleScholar&v=2.1&it=r&linkaccess=abs&issn=23201770&p=HRCA&sw=w
Labial fusion is sealing of labia minora in midline, also known as labial adhesion or labial agglutination or synechia vulvae. This condition is common in pre-pubertal females usually asymptomatic when oestrogen levels are low and commonly resolves spontaneously post-puberty if unresolved medical treatment includes use of estrogen cream or betamethasone cream application, very rarely surgical treatment required, if not responding to medical treatment due to dense adhesions. […] This case report is unusual as it has presented in a post- pubertal female requiring surgical management.
- #13 Bladder Outlet Obstruction Due to Recurrent Complete Labial Fusion in Postmenopausal WomanâCase Reporthttps://www.mdpi.com/2075-4418/14/23/2659?type=check_update&version=2
Labial fusion is a rare condition typically observed in prepubescent girls, but it can also occur in postmenopausal women due to estrogen deficiency. […] The incidence of labial adhesions in children is approximately 0.6â1.4%, while the incidence in the elderly population remains unclear. […] In postmenopausal women, these adhesions may also affect the labia majora. […] The precise cause of labial adhesion is not fully understood. […] In acquired cases, the potential underlying factors include estrogen deficiency, injuries, Behçetâs disease, StevensâJohnson syndrome, mucous membrane pemphigoid, and graft-versus-host disease. […] In our patient, there was no history of vulvar lesions, repeated infections, chronic inflammatory conditions, or local trauma but only atrophy. […] Surgical intervention remains the primary treatment option for complete labial fusion in postmenopausal women, particularly in cases involving bladder outlet obstruction or significant urinary symptoms.
- #14 Labial Adhesions – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK470461/
Labial adhesion may affect up to 2% of prepubertal girls, with the typical age of presentation for labial adhesions at two years of age. […] The exact cause of labial fusion remains unknown. However, it is believed to occur in a low estrogen state. […] The condition is believed to be due to inflammation of the labia in a low-estrogen environment. […] Some studies report a rate of recurrence from 11% to 14% with either topical or surgical management.
- #15 An Unusual Cause of Urinary Pseudoincontinence: Two Rare Cases of Labial Fusion in Adolescent and Postmenopausal Womenhttps://www.jsafog.com/abstractArticleContentBrowse/JSAFOG/21668/JPJ/fullText
Labial adhesions are usually a pediatric condition and are asymptomatic. They can also occur in postmenopausal age group albeit uncommon due to hypoestrogenism causing senile vaginitis. […] Labial fusion is defined as the partial or complete fusion of the labia minora causing partial or complete occlusion of the vaginal and/or urethral opening. It can be congenital or acquired. […] Labial fusion is often an acquired condition typically seen in prepubertal girls, usually below 6 years of age. It is uncommonly seen in postmenopausal woman and even more rarely in the reproduction age group. […] Estrogen deficiency plays a major role in the development of labial adhesion, thereby explaining its high incidence rate in the prepubertal females and it is the cause in the postmenopausal age. […] Although uncommon, labial fusion can occur in the postpubertal females, one needs to have high index of suspicion to diagnose this rare condition as the patient often presents with common gynecological symptoms of difficult menstruation and urinary dribbling.
- #16 Labial Fusion (Adhesion on Genital Lips)https://www.eserdag.com/en/labial-fusion-adhesion-on-genital-lips
Labial fusion is the condition of the inner genital lips (labia minora) sticking together, also known as „labial adhesion” or „labial synechiae”. […] The incidence of labial fusion in infants is between 0.6-3%. […] The diagnosis of labia fusion is based on gynecological examination of the genital area. […] The most common complaints in labial synechia are frequent urinary tract infections and frequent vaginal infections. […] There are two periods in which labial fusions are most common: infancy/childhood, called the „prepubertal” period, and the postmenopausal period. […] The main reason for labial fusion that occurs during menopause is hypoestrogenism, that is, the low estrogen level that occurs with menopause. […] Labial synechiae are frequently associated with chronic and inflammatory diseases of the genital area, especially in the adult age group. […] Early diagnosis and treatment of patients with labial fusion and genital adhesions are important.
- #17 :: JMM :: Journal of Menopausal Medicinehttps://e-jmm.org/DOIx.php?id=10.6118/jmm.22020
Labial adhesions in postmenopausal women are caused by various inflammatory processes in the context of estrogen deficiency. […] Early diagnosis and treatment of LS can prevent disease progression, leading to labial adhesions and malignancy. […] Labial adhesion is defined as the partial or complete fusion of the labia minora or majora that has an incidence of 2% among prepuberal females. […] Among dermatologic conditions associated with labial adhesion are lichen sclerosus (LS) and lichen planus. […] The above case shows a striking clinical presentation of vulvar HHD that masked the diagnosis of LS and led to development of labial adhesion. […] Treatment for mild cases of labial adhesion includes treating the underlying condition together with TCS and topical estrogen creams. […] Recurrence of adhesions has been reported in 14%20% of patients who have undergone surgical or manual separation; thus it is important to emphasize topical estrogen application and regular digital separation of the vulva, especially in patients who are not sexually active. […] Prevention of chronic complications of LS such as labial adhesion may improve the quality of life of patients affected by this condition.
- #18 Labial adhesion – diagnostics and treatment | Tidsskrift for Den norske legeforeninghttps://tidsskriftet.no/en/2017/01/original-article/labial-adhesion-diagnostics-and-treatment
Labial adhesion is relatively common, but the condition is little known among doctors and parents. The article assesses treatment in the specialist health service. […] Labial adhesion is relatively common, and in the literature it is estimated to occur in 0.6-3.3 % of prepubertal girls. Doctors should therefore be aware of the condition, which is also referred to in the Norwegian Electronic Medical Handbook. […] The vast majority of girls with labial adhesion are asymptomatic, and this is the case irrespective of age. However, the condition may be associated with various symptoms, for example a stinging pain on urination when the adhesion resolves, which may be misinterpreted as a urinary infection. […] In this review of patient records, just over half of patients for whom the outcome is known achieved complete opening of the vagina after treatment with topical oestrogen or surgery.

labial fusion/labial adhesions may be defined as the partial or complete adherence of the apposing vulval labia minora […] most frequently seen in infants and very young children […] labial adhesions and fusion in children in the absence of any other pathology is well documented […] many cases are discovered incidentally during routine examination […] only extremely rarely been noted to be present at birth – most authors regard it as an acquired condition […] „physiological” fusion is postulated to arise in infants and young children with endogenously low estrogen levels who may or may not have an associated inflammatory condition such as vulvovaginitis […] Leung et al found that labial fusion was most frequently seen in infants and young children, with a peak incidence of 3.3% in children ages 13 to 23 months
- #20 Labial Adhesions – MD Searchlighthttps://mdsearchlight.com/womens-health/labial-adhesions/
Labial fusion, which is the joining of the lips around the vulva, often doesn’t show obvious signs or symptoms. It’s usually accidentally discovered during a routine check-up. This fusion usually happens near the clitoris and involves thin fibrotic tissue a kind of scar tissue. This fusion can be slight or complete, even blocking the entrance to the vagina. […] Research suggests that women with labial fusion before puberty have an increased risk of UTIs. This makes it very important to conduct a physical exam, particularly of the genitourinary region. If labial adhesions are successfully resolved, the risk of UTIs can go down. […] Labial adhesions can impact as much as 2% of girls before puberty. […] Labial adhesions do not typically require any special tests for diagnosis. The condition is diagnosed based on a doctor’s clinical examination and evaluation, which includes gathering information from symptoms, medical history, and physical examination. However, if treatment is needed, the doctor may recommend the following tests: – Urinalysis: This test may be done to check for urinary tract infections, which can be a common complication of labial adhesions.
