The other main type is otitis media with effusion (OME), typically not associated with symptoms, [1] although occasionally a feeling of fullness is described; [4] it is defined as the presence of non-infectious fluid in the middle ear which may persist for weeks or months often after an episode of acute otitis media. [4] Chronic suppurative ...
A conductive hearing loss is characterized by a difference of at least 15 decibels between the air conduction threshold and bone conduction threshold at the same frequency. On an audiogram, the "x" represents responses in the left ear at each frequency, while the "o" represents responses in right ear at each frequency.
One review paper wrote that 83% of children had at least one episode of acute otitis media by 3 years of age. [10] Worldwide, there are 709 millions cases of acute otitis media every year. [36] Hearing loss globally due to ear infection is estimated to be 30 people in every 10,000. [36]
The majority of tympanic membrane retractions do not cause any symptoms. Some cause hearing loss by restricting sound-induced vibrations of the eardrum. Permanent conductive hearing loss can be caused by erosion of the ossicles (hearing bones). Discharge from the ear often indicates that the retraction pocket has developed into a cholesteatoma.
Otology also includes surgical treatment of conductive hearing loss, such as stapedectomy surgery for otosclerosis. Neurotology (a related field of medicine and subspecialty of otolaryngology ) is the study of diseases of the inner ear, which can lead to hearing and balance disorders.
Since the inner ear is not directly accessible to instruments, identification is by patient report of the symptoms and audiometric testing. Of those who present to their doctor with sensorineural hearing loss, 90% report having diminished hearing, 57% report having a plugged feeling in ear, and 49% report having ringing in ear ().
Hearing loss is a partial or total inability to hear. [5] Hearing loss may be present at birth or acquired at any time afterwards. [6] [7] Hearing loss may occur in one or both ears. [2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. [8]
