Zatkany kanał słuchowy
Patofizjologia i mechanizm

Woskowina uszna (cerumen) jest naturalnym wydzieleniem gruczołów woskowinowych i łojowych w zewnętrznej jednej trzeciej przewodu słuchowego, pełniącym funkcje ochronne, nawilżające i antybakteryjne. Fizjologiczny mechanizm samooczyszczania przewodu słuchowego opiera się na migracji nabłonka i ruchach szczęki, które usuwają woskowinę na zewnątrz. Zatkanie kanału słuchowego woskowiną (cerumen impaction) powstaje w wyniku nadprodukcji cerumenu, zaburzeń migracji nabłonka, mechanicznego przepychania woskowiny (np. przez patyczki kosmetyczne, aparaty słuchowe) oraz czynników anatomicznych (wąskie, zakrzywione kanały) i wiekowych zmian w składzie i konsystencji woskowiny. Zatkanie nie musi całkowicie blokować kanału, aby powodować objawy, takie jak przewodzeniowy ubytek słuchu, uczucie pełności, ból, szumy uszne, zawroty głowy czy kaszel odruchowy.

Patogeneza zatkania kanału słuchowego

Woskowina uszna (łac. cerumen) jest naturalną substancją wytwarzaną przez organizm, która pełni istotną funkcję w utrzymaniu zdrowia ucha. Wytwarzana jest przez gruczoły woskowinowe i łojowe zlokalizowane w zewnętrznej jednej trzeciej części przewodu słuchowego zewnętrznego, a następnie miesza się ze złuszczonymi komórkami nabłonka 12. Cerumen stanowi ochronną warstwę, która oczyszcza, nawilża i chroni przewód słuchowy przed kurzem, brudem i infekcjami 34.

Naturalny mechanizm samooczyszczania kanału słuchowego

W normalnych warunkach woskowina jest naturalnie usuwana z przewodu słuchowego poprzez mechanizm samooczyszczania, wspierany przez ruchy szczęki podczas mówienia i żucia 25. Proces migracji woskowiny z głębszej części kanału słuchowego do jego ujścia zachodzi dzięki naturalnemu wzorowi migracji nabłonka 6. Gdy woskowina dociera do ujścia kanału słuchowego, jest wymywana lub odpada, a jej miejsce zajmuje nowa woskowina 4. Ten mechanizm samooczyszczania może jednak zawieść u niektórych osób, prowadząc do kumulacji i zablokowania przewodu słuchowego 1.

Przyczyny gromadzenia się woskowiny

Istnieje wiele czynników, które mogą przyczynić się do nadmiernego gromadzenia się woskowiny i zatkania kanału słuchowego:

  • Nadprodukcja woskowiny – niektóre osoby po prostu wytwarzają więcej woskowiny niż inne 37.
  • Nieprawidłowe czyszczenie uszu – najczęstszą przyczyną zatkania kanału słuchowego jest używanie patyczków kosmetycznych lub innych przedmiotów do czyszczenia uszu, które zamiast usuwać woskowinę, popychają ją głębiej do kanału słuchowego 48.
  • Używanie aparatów słuchowych i zatyczek do uszu – mogą one blokować naturalną migrację woskowiny i stymulować gruczoły do nadmiernej produkcji cerumenu 15.
  • Anatomiczne właściwości przewodu słuchowego – wąskie, zakrzywione lub owłosione kanały słuchowe utrudniają naturalną eliminację woskowiny 9.
  • Zmiany związane z wiekiem – wraz z wiekiem gruczoły woskowinowe stopniowo zanikają i stają się mniej liczne, co prowadzi do wytwarzania suchszej woskowiny, która trudniej migruje przez kanał słuchowy 1011.
  • Genetyczne uwarunkowania – woskowina może być fenotypowo sucha lub mokra, co może wpływać na prawdopodobieństwo wystąpienia jej zatkania 10.
  • Stany chorobowe – niektóre choroby skóry i egzema mogą prowadzić do nadmiernej produkcji woskowiny 12.
  • Ekspozycja na kurz i brud – praca w zapylonym środowisku może przyczyniać się do gromadzenia się woskowiny 9.

Mechanizm powstawania zatkania

Zatkanie kanału słuchowego woskowiną (łac. cerumen impaction) definiuje się jako nagromadzenie woskowiny, które powoduje objawy lub uniemożliwia ocenę kanału słuchowego, błony bębenkowej lub układu audiowestybularnego 1013. Do zatkania nie jest konieczne całkowite zablokowanie kanału słuchowego 14.

Mechanizm powstawania zatkania kanału słuchowego polega na:

  • Niepowodzeniu mechanizmu samooczyszczania – gdy naturalny proces migracji woskowiny zostaje zakłócony, zaczyna się ona gromadzić 15.
  • Zaburzeniu migracji nabłonka – przewlekłe podrażnienie kanału słuchowego przez ciała obce (np. patyczki do uszu) może prowadzić do zmian w skórze kanału słuchowego i upośledzać normalną migrację nabłonka 15.
  • Mechanicznym blokowaniu kanału – gdy woskowina jest przepychana głębiej do kanału słuchowego, który ma kształt klepsydry, może dojść do zablokowania w jego najwęższej części 16.
  • Utwardzeniu woskowiny – sucha woskowina może stać się zbyt twarda, aby zostać naturalnie usunięta, co prowadzi do jej gromadzenia się 3.

Patofizjologiczne następstwa zatkania kanału słuchowego

Zatkanie kanału słuchowego woskowiną może prowadzić do różnych konsekwencji patofizjologicznych:

  • Przytłumiony słuch i utrata słuchu – nagromadzona woskowina może utrudniać przepływ fal dźwiękowych do błony bębenkowej, powodując przewodzeniowy ubytek słuchu 117.
  • Ucisk na błonę bębenkową – nadmierna ilość woskowiny może uciskać błonę bębenkową, powodując uczucie pełności w uchu, ból i zaburzenia słuchu 1.
  • Zwiększone ryzyko infekcji – woskowina może tworzyć barierę zatrzymującą wilgoć w kanale słuchowym, co sprzyja rozwojowi bakterii i grzybów 118.
  • Szumy uszne (tinnitus) – zablokowany kanał słuchowy może powodować dzwonienie lub brzęczenie w uszach 1719.
  • Zawroty głowy – ucisk woskowiny na struktury błędnika może zakłócać mechanizmy równowagi 20.
  • Kaszel odruchowy – w niektórych przypadkach nadmierna ilość woskowiny może wywoływać odruchowy kaszel 21.

Czynniki ryzyka i predyspozycje

Niektóre grupy osób są bardziej narażone na zatkanie kanału słuchowego woskowiną:

  • Osoby starsze – woskowina uszna staje się suchsza i trudniejsza do naturalnego usunięcia wraz z wiekiem. Badania pokazują, że problem zatkania kanału słuchowego dotyczy nawet 57% osób starszych w domach opieki, w porównaniu do 5% młodszych, zdrowych dorosłych 211.
  • Użytkownicy aparatów słuchowych – noszenie aparatów słuchowych może blokować naturalne usuwanie woskowiny i stymulować jej nadprodukcję 117.
  • Osoby z wąskimi kanałami słuchowymi – anatomiczne predyspozycje mogą utrudniać naturalną migrację woskowiny 22.
  • Osoby z zespołem Downa – ze względu na mniejszy, zakrzywiony kształt kanału słuchowego 17.
  • Osoby z niepełnosprawnością intelektualną – zatkanie kanału słuchowego występuje u około jednej trzeciej pacjentów z niepełnosprawnością intelektualną 2.
  • Osoby z chorobami skóry – stany takie jak egzema mogą przyczyniać się do nadmiernej produkcji woskowiny 12.
  • Osoby z cukrzycą – u pacjentów z cukrzycą pH woskowiny jest zwykle wyższe, co zwiększa ryzyko zakażeń bakteryjnych 2324.
  • Pacjenci stosujący leki przeciwkrzepliwe – są bardziej narażeni na krwawienie w kanale słuchowym podczas usuwania woskowiny 2524.
  • Pracownicy w zapylonych środowiskach – osoby pracujące w stolarniach lub zakurzonych miejscach, gdzie cząsteczki mieszają się z woskowiną i szybko twardnieją 22.

Fizjologia wytwarzania woskowiny

Aby w pełni zrozumieć patogenezę zatkania kanału słuchowego, należy poznać fizjologiczny proces wytwarzania woskowiny:

Struktura i skład woskowiny

Woskowina uszna składa się z różnych komponentów:

  • Wydzieliny gruczołów – produkowane przez gruczoły woskowinowe i łojowe w zewnętrznej części kanału słuchowego 6.
  • Złuszczone komórki nabłonka – stanowią znaczącą część woskowiny 2.
  • Włosy – które wypadły w kanale słuchowym 6.
  • Bakterie – normalnie występujące na powierzchni skóry 6.

Woskowina może występować w dwóch genotypowo uwarunkowanych fenotypach: suchym i mokrym 10. Suchy fenotyp jest najczęstszy u osób pochodzenia azjatyckiego i rdzennych Amerykanów, podczas gdy mokry fenotyp występuje częściej u osób pochodzenia europejskiego i afrykańskiego 26.

Funkcje ochronne woskowiny

Woskowina pełni wiele istotnych funkcji fizjologicznych:

  • Ochrona kanału słuchowego – woskowina tworzy barierę ochronną przed kurzem, brudem i mikroorganizmami 27.
  • Właściwości antybakteryjne – zapobiega infekcjom ucha 28.
  • Nawilżanie – utrzymuje delikatną skórę kanału słuchowego nawilżoną, zapobiegając jej wysuszeniu i swędzeniu 6.
  • Właściwości hydrofobowe – odpycha wodę, zapobiegając uszkodzeniom wodnymi kanału słuchowego i błony bębenkowej 6.
  • Samoczyszczenie – zapewnia mechanizm usuwania złuszczonych komórek skóry i innych drobnych zanieczyszczeń 27.

Zaburzenia mechanizmu samooczyszczania

Fizjologiczny mechanizm samooczyszczania kanału słuchowego może zostać zakłócony przez:

  • Nieprawidłowe czyszczenie uszu – użycie patyczków kosmetycznych, które mogą prowadzić do stałego podrażnienia kanału słuchowego i nadmiernej produkcji woskowiny 1.
  • Zmiany w składzie woskowiny – częste wprowadzanie ciał obcych do kanału słuchowego może nie tylko przyspieszać produkcję woskowiny, ale również potencjalnie zmieniać jej skład 1.
  • Zawężenie kanału słuchowego – niektóre infekcje ucha, takie jak zapalenie ucha zewnętrznego, mogą powodować zwężenie zewnętrznego kanału słuchowego z powodu stanu zapalnego, co utrudnia naturalną migrację woskowiny 12.
  • Kostne naroślaegzostozy lub osteomata mogą zakłócać samooczyszczający mechanizm ucha 29.

Konsekwencje nieleczonego zatkania kanału

Nieleczone zatkanie kanału słuchowego woskowiną może prowadzić do różnych powikłań:

Zaburzenia słuchu

Zatkanie kanału słuchowego woskowiną jest jedną z najczęstszych przyczyn przejściowej utraty słuchu 3031. Gdy woskowina całkowicie blokuje kanał słuchowy, dźwięk może być przewodzony tylko przez kości, co powoduje spadek słyszalności o 20-30 dB 22. Nieleczona utrata słuchu może prowadzić do wycofania społecznego, słabszej wydajności w pracy, a nawet łagodnej paranoi 17.

Infekcje ucha

Nadmierne nagromadzenie woskowiny w kanale słuchowym może stworzyć wilgotne środowisko idealne dla wzrostu bakterii lub grzybów, prowadząc do stanu zapalnego i infekcji kanału słuchowego 18. Zatkanie woskowiną może także zatrzymywać wodę, bakterie i zanieczyszczenia, zwiększając ryzyko rozwoju zapalenia ucha zewnętrznego 18.

Zaburzenia równowagi i zawroty głowy

Zatkanie kanału słuchowego może zakłócać delikatne mechanizmy równowagi w uchu wewnętrznym, powodując zawroty głowy lub uczucie wirowania 32. Przedłużające się zaniedbanie może nasilić problemy związane z równowagą, prowadząc do utrzymujących się zawrotów głowy 33.

Szumy uszne (tinnitus)

Nadmierna ilość woskowiny może powodować tinnitus, czyli stałe dzwonienie lub brzęczenie w uszach 1729. W przypadku zatkania kanału słuchowego woskowiną, szumy uszne mogą być spowodowane stymulacją nerwów w kanale słuchowym przez nacisk woskowiny 19.

Wpływ na funkcje poznawcze

U osób starszych utrata słuchu spowodowana zatkaniem kanału słuchowego woskowiną może być związana z upośledzeniem funkcji poznawczych 34. Nieleczone zatkanie kanału słuchowego może prowadzić do izolacji społecznej i pogorszenia funkcji poznawczych, szczególnie u osób starszych 35.

Podsumowanie mechanizmu patogenetycznego

Zatkanie kanału słuchowego woskowiną jest wynikiem złożonej interakcji między nadprodukcją woskowiny, zaburzeniem jej naturalnej migracji oraz czynnikami anatomicznymi i behawioralnymi. Proces patogenetyczny można podsumować następująco:

  1. Nadmierna produkcja woskowiny lub niepowodzenie mechanizmu samooczyszczania prowadzi do jej gromadzenia się w kanale słuchowym.
  2. Nieprawidłowe praktyki czyszczenia uszu, używanie aparatów słuchowych lub zatyczek może przepychać woskowinę głębiej do kanału słuchowego.
  3. Zgromadzona woskowina może utwardzać się i przylegać do ścian kanału słuchowego, tworząc blokadę.
  4. Blokada może uciskać błonę bębenkową lub blokować przepływ fal dźwiękowych, powodując objawy słuchowe i pozasłuchowe.
  5. Nieleczone zatkanie może prowadzić do dalszych komplikacji, w tym infekcji, trwałej utraty słuchu i zaburzeń równowagi.

Zrozumienie patogenezy zatkania kanału słuchowego woskowiną jest kluczowe dla jego skutecznej profilaktyki i leczenia. Szczególną uwagę należy zwrócić na edukację pacjentów dotyczącą prawidłowej higieny uszu oraz wczesnego rozpoznawania i leczenia objawów zatkania kanału słuchowego 36.

    https://www.ncbi.nlm.nih.gov/books/NBK448155/
    Production of cerumen (earwax) is a normal and naturally occurring process. […] However, this self-cleaning mechanism fails in certain individuals, and cerumen can become impacted. Excessive buildup of cerumen is likely underdiagnosed and undertreated. […] Cerumen impaction can occlude the external auditory canal or press against the tympanic membrane, potentially causing ear fullness, conductive hearing loss, itching, and pain. […] It is often seen in patients who routinely wear hearing aids or earplugs and those with exostoses or anatomic abnormalities of the external ear canal. […] Impacted cerumen may also contain neutrophils and has a much higher likelihood of bacterial or fungal colonization. […] While there is a certain baseline rate of cerumen production, frequent insertion of foreign objects into the external auditory canal, such as cotton swabs and certain types of hearing aids or earbuds, often accelerates cerumen production and potentially changes its composition.

    https://www.aafp.org/pubs/afp/issues/2018/1015/p525.html
    Cerumen, or earwax, is a combination of glandular secretions and desquamated epithelial cells that cleans, protects, and lubricates the external auditory canal. Cerumen is typically expelled from the ear canal spontaneously via a self-cleaning mechanism that is assisted by jaw movement. In some persons, however, this mechanism fails and cerumen becomes impacted. Cerumen impaction is defined as an accumulation of cerumen that causes symptoms or prevents assessment of the ear canal, tympanic membrane, or audiovestibular system; complete obstruction is not required. Cerumen impaction is a common reason for consultation with primary care physicians and is present in about 10% of children, 5% of healthy adults, up to 57% of older persons in nursing homes, and one-third of patients with mental retardation.
  • #3 Earwax Blockage: Symptoms, Causes & Removal
    https://my.clevelandclinic.org/health/diseases/14428-ear-wax-buildup–blockage
    Earwax blockage happens when earwax (cerumen) builds up inside your ear canal. […] Cerumen impaction is the medical term for earwax blockage. Earwax (cerumen) plays an important role in ear health. It cleans your ears and protects them from dust, dirt and infection. […] Despite its many benefits, earwax can cause issues if too much of it builds up. Cerumen impaction may result in ear pain, itchiness, ringing in your ears, hearing loss or other issues. […] Some people get earwax buildup simply because they naturally produce more earwax. […] You can also get earwax impaction if you have dry or hard earwax. […] If left untreated, excessive earwax may cause earwax impaction symptoms to worsen. […] Impacted cerumen treatments involve both at-home and in-office methods, including solutions that dissolve earwax, ear irrigation, and in-office earwax removal. […] Many people use cotton swabs to clean their ears. But research shows that cotton swabs can actually cause more earwax production. […] However, if earwax builds up, it can cause issues like irritation, itchiness and hearing loss.
  • #4 Earwax blockage – Symptoms & causes – Mayo Clinic
    https://www.mayoclinic.org/diseases-conditions/earwax-blockage/symptoms-causes/syc-20353004
    Earwax blockage occurs when earwax (cerumen) builds up in your ear or becomes too hard to wash away naturally. […] The wax in your ears is made by glands in the skin of your outer ear canal. The wax and tiny hairs in these passages trap dust and other materials that could damage deeper parts of your ear, such as your eardrum. […] In most people, a small amount of earwax regularly makes its way to the ear opening. At the opening, it’s washed away or falls out as new wax replaces it. If your ears make too much wax or if earwax isn’t cleared well enough, it may build up and block your ear canal. […] Earwax blockages often happen when people try to get earwax out on their own by using cotton swabs or other items in their ears. This usually just pushes wax deeper into the ear, rather than removing it.
  • #5 Diagnosis and Management of Cerumen Impaction | AAFP
    https://www.aafp.org/pubs/afp/issues/2009/1101/p1011.html
    Cerumen, or earwax, is normally expelled from the ear canal by a self-cleaning mechanism assisted by jaw movement. […] Occasionally this mechanism fails, and accumulation of cerumen can lead to symptoms such as pain, itching, tinnitus, and hearing loss. […] The use of hearing aids or earplugs may cause stimulation of cerumen glands, leading to excessive cerumen production. […] Cerumen generally is removed from the ear canal naturally, so observation over time can be offered as a reasonable management strategy in asymptomatic patients with nonimpacted cerumen. […] In some cases, treatment may be indicated even if the patient is not symptomatic. […] Physicians should evaluate the need for treatment in these patients if the ear canal is obstructed. […] The mechanism by which nonwater-, nonoil-based agents work is not known.
  • #6 The scoop on earwax – Mayo Clinic News Network
    https://newsnetwork.mayoclinic.org/discussion/the-scoop-on-earwax/
    Cerumen, commonly called earwax, is found in the ear canal. It’s made up of several components. […] Earwax is made up of secretions from these glands, skin cells that have sloughed off, hairs that have shed and usual bacteria that lives on the skin’s surface. […] Earwax has many jobs. It moisturizes the fragile ear canal skin, and prevents dry and itchy ears. It also protects the ear canal skin from infection, and traps dust and other foreign particles. It has antibacterial properties to protect your ears from unhealthy bacteria. Finally, its water-repelling features prevent water damage to the ear canal and eardrum. […] Earwax migrates from deeper in the ear canal to the ear canal opening via different mechanisms, including normal skin migration pattern and movement of the jaw joint. These mechanism help push earwax outward toward the ear canal opening.
  • #7 The scoop on earwax – Mayo Clinic News Network
    https://newsnetwork.mayoclinic.org/discussion/the-scoop-on-earwax/
    Some people produce an excessive amount of earwax. This can be due to various causes. Other people have issues with wax blockage because they put items into their ears, thus embedding the wax deeper into the ear canal. […] Hydrogen peroxide is a cerumenolytic. This means that it softens, loosens, dissolves and breaks down earwax. […] Never attempt to dig out excess or hard earwax using a paper clip, Q-tip or another small object. These instruments can push the earwax deeper into the ear canal, which can cause an earwax impaction.
  • #8 Earwax: Symptoms, Causes, Treatment, Removal, and Prevention
    https://www.webmd.com/a-to-z-guides/ear-wax
    Earwax blockage is one of the most common ear problems doctors see. […] The most common cause of impactions is the use of cotton swabs (and other objects such as bobby pins and rolled napkin corners), which can remove superficial wax but also pushes the rest of the wax deeper into the ear canal. […] Blockage, or impaction, often occurs when the wax gets pushed deep within the ear canal. […] Earwax blockage can often be prevented by avoiding the use of cotton-tipped swabs (like Q-tips) and other objects that push the wax deeper into the ear canal.
  • #9 Will Impacted Ear Wax Fix Itself?
    https://www.earworx.com.au/will-impacted-ear-wax-fix-itself/
    Impacted earwax is where wax accumulates in the ear canal to the point where it causes symptoms. […] While it is true that our ears are self-cleaning, and wax should be carried out of the ear canal naturally, if your ear wax has built up to the point that it is symptomatic, and impacted, you may need a little more help. […] For a variety of reasons, this self-cleaning method can be disrupted, and this is where the wax can become impacted and hence problematic. […] Excessive or impacted wax affects one in 10 children and one in 20 adults. Furthermore, it affects over a third of geriatric and developmentally delayed populations. […] Some of the most common causes of ear wax impaction include: The use of cotton tips and other items to remove superficial wax, Wearing hearing aids, or using earplugs frequently, Working in a dusty or dirty environments, Stress, Genetics some people overproduce earwax, Having narrow, curvy or hairy ear canals, Surfing or swimming in cold water.
  • #10 Cerumen Management: An Updated Clinical Review and Evidence-Based Approach for Primary Care Physicians
    https://pmc.ncbi.nlm.nih.gov/articles/PMC6990605/
    Cerumen impaction is defined as the symptomatic accumulation of cerumen, or cerumen accumulation that prevents diagnostic assessment. […] Cerumen impaction can also occur when objects are inserted into the ear canal. The use of hearing aids and ear plugs can obstruct cerumen elimination, and cotton swabs (Q-tips) commonly cause cerumen to be forced deeper into the ear canal. […] Cerumen glands progressively atrophy and become less numerous with age, resulting in drier cerumen. The drier cerumen is less readily transported by the epithelial conveyor mechanism. […] Cerumen can be divided into 2 genetically determined phenotypes: dry and wet. […] It has been asserted that having a wet or dry cerumen phenotype may promote or protect against cerumen impaction, and that phenotype may also affect the efficacy of different cerumen removal techniques.
  • #11 Ear wax management
    https://www.racgp.org.au/afp/2015/october/ear-wax-management
    Furthermore, the ceruminous glands atrophy with age and produce a drier wax that migrates more slowly. […] Cerumen impaction is present in up to 57% of older patients, compared with 5% of younger, healthy adults. […] The first-line option for treatment of symptomatic patients is cerumenolytics. The use of cerumenolytic agents, namely eardrops such as docusate sodium, increases the likelihood of cerumen clearance, compared with no treatment. […] However, there is no significant difference in effectiveness between water-based or oil-based drops. […] Patients with hard impaction or ear canal disease may require irrigation or manual removal under microscope by a trained doctor or an ear, nose and throat (ENT) specialist. […] Syringing can damage the delicate skin of the ear canal and the tympanic membrane itself.
  • #12 Earwax Buildup Barnstaple – Devon Ear Clinic
    https://devon-ear-clinic.co.uk/earwax-buildup-barnstaple/
    The ear canal is lined with sebaceous and ceruminous glands that produce a greasy, viscous substance called cerumen, more commonly known as earwax. […] Any disruption in this natural migratory process can lead to the progressive buildup and hardening of cerumen within the ear canal known as impaction. […] An overproduction of cerumen can also overwhelm the self-cleaning mechanism of the ear and cause an earwax buildup or blockage. […] The following factors can lead to the buildup and impaction of cerumen, resulting in an ear blockage: […] Certain ear infections such as swimmers ear can cause a narrowing of the outer ear canal due to inflammation and can pave the way for earwax accumulation. […] Dermatological conditions such as eczema are characterised by hardened wax secretions and dry, flaky skin, both of which can contribute to excessive cerumen accumulation.

    https://criticalcarenow.com/docusate-for-cerumen-impaction-i-sht-you-not/
    Cerumen, a.k.a. earwax, is a substance that cleans, protects, and lubricates the external auditory canal and is formed when glandular secretions from the outer two-thirds of the ear canal mix with exfoliated squamous epithelium. Cerumen is composed of secretions and sloughed epithelial cells, and as it migrates laterally, may mix with hair and other particulate matter. It is normally naturally extruded by a self-cleaning mechanism that causes it to migrate out of the ear canal assisted by jaw movement; however, a failure of this mechanism may lead to accumulation and occlusion in one or both ears. Ultimately, this may cause discomfort, hearing loss, tinnitus, dizziness, ear fullness, itching, otalgia, discharge, odor, chronic cough, and contribute to otitis externa. […] According to the American Academy of Otolaryngology-Head and Neck Surgery guideline on earwax, cerumen impaction is defined as an accumulation of cerumen that causes symptoms or inhibits the assessment of the ear canal, tympanic membrane, audiovestibular system, or both.
  • #14 ABOUT EARWAX – OTIBLOCK®
    https://otiblock.com/about-ear-wax/
    Earwax, also known as cerumen, is a physiological substance that cleans, protects and lubricates the ear canal. […] This substance is a natural secretion from the sebaceous and apocrine glands to capture dust and dirt, as well as repelling water from the tympanic membrane. Put simply, the functions of earwax are to clean and lubricate the ear canal and protect it from bacteria, fungus, and insects. […] Despite this self-cleaning mechanism, a lot of people tend to suffer from earwax accumulation and impaction because of excessive production or reduced elimination efficacy. […] Impaction does not necessarily mean that the ear canal is completely obstructed. […] While often harmless, blockage of the ear canal by earwax can lead to a host of symptoms. […] In addition, earwax impaction can make diagnostic assessment more difficult, as it prevents your doctor or nurse from seeing the external ear canal and/or tympanic membrane correctly.
  • #15 Ear wax management
    https://www.racgp.org.au/afp/2015/october/ear-wax-management
    Ear wax is the product of ceruminous and sebaceous gland secretions, mixed with exfoliated squamous epithelium. It forms a protective film, has antibacterial properties and provides lubrication to the ear canal. It is the ears self-cleaning mechanism, and traps dust and dirt, which are then excreted from the ear canal in a medial to lateral direction. This is aided by epithelial migration and movement of the jaw. […] When the self-cleaning mechanism is disrupted, wax accumulates and can become impacted. Narrowing or obstruction of the ear canal, due to anatomical variations or infectious or dermatological diseases, can interfere with the normal migratory process. […] Irritation from foreign objects placed in the ear (eg cotton tips, hearing aids and ear plugs) can cause chronic changes to the skin of the ear canal and impair normal epithelial migration. Cotton buds also tend to push cerumen deeper into the ear canal, and hearing aids and ear plugs obstruct the ear canal and contribute to cerumen accumulation over time.
  • #16
    https://med.uth.edu/orl/2020/01/09/earwax-cerumen-impaction/
    Earwax blockage is one of the most common causes of hearing loss. […] Wax blockage is often caused by attempts to clean the ear with cotton swabs. […] Most cleaning attempts merely push the wax deeper into the ear canal which is shaped like an hourglass, causing a blockage at the narrowing part of the ear canal. […] Discontinue the habit of inserting cotton-tipped swabs or other objects into the ear canals. […] This condition is called cerumen impaction. […] Manual removal of earwax is also effective. […] Manual removal is preferred if your ear canal is narrow, the eardrum has a perforation or tube, other methods have failed, or if you have skin problems affecting the ear canal, diabetes or a weakened immune system.
  • #17 Earwax – Wikipedia
    https://en.wikipedia.org/wiki/Earwax
    Excess or compacted cerumen is the buildup of ear wax causing a blockage in the ear canal and it can press against the eardrum or block the outside ear canal or hearing aids, potentially causing hearing loss. […] Excessive earwax may impede the passage of sound in the ear canal, causing mild conductive hearing loss, pain in the ear, itchiness, or dizziness. […] Untreated impacted wax can result in hearing loss, social withdrawal, poor work function, and mild paranoia. […] Hearing aids may be associated with increased earwax impaction by blocking earwax from leaving the ear canal. […] Excessive earwax can also cause tinnitus, a constant ringing in the ears, ear fullness, hearing loss and ear pain. […] Impacted earwax is more common in those with Down’s syndrome, due to the smaller, curved shape of the ear canal.

    Earwax should be left alone unless it is blocking your doctors view of the ear canal and eardrum, or causing symptoms. […] In a minority of people, this self-cleaning mechanism may fail, leading to an accumulation of earwax and various problems. […] Hearing loss – A complete or near complete wax blockage of the ear canal or wax in contact with the eardrum may cause hearing loss, specifically conductive hearing loss. […] Cerumen may create a dam that retains moisture in the ear canal, predisposing to infection. […] Excessive accumulation of cerumen in the ear canal can create a moist environment ideal for bacterial or fungal growth, leading to inflammation and infection of the ear canal.
