what does the auditory canal do in your ear
Otolaryngologist GÃ¼zin Akkuzu lists the 8 factors that cause ear congestion: Ear Wax Build-Up: This is one of the most frequently encountered causes of ear congestion. Sometimes, the ear wax builds up in the external auditory canal due to hypersecretion or the inadequacy of the external auditory canalâs width. The build-up does not cause any disturbance until it fills the canal completely but leads to a sudden feeling of blockage once it fully clogs the canal. Foreign Objects in the External Auditory Canal: Foreign objects may cause ear congestion if they block the canal entirely. External Ear Infection: External auditory canal infections generally arise when the canal remains damp for a long time due to trapping of water in ears in the pool, sea or shower. The water retention in the external auditory canal causes pain as well as ear congestion for patients. Middle Ear Infection: The middle ear consists of a hollow space filled with air in which three ossicles serve to transmit sounds.
