otitis media Inflammation of the middle ear marked by pain, fever, abnormal hearing, hearing loss, tinnitus, and vertigo. This is the most common "ear infection." There are different types, such as acute otitis media, which is a bacterial infection in the middle ear, usually secondary to an upper respiratory infection; chronic otitis media, which is a permanent perforation of the tympanic membrane; and serous otitis media, which is an effusion in the middle ear and which arises from incomplete resolution of an acute otitis media or obstruction of the eustachian tube. A common surgical procedure to aid in the reduction of infectious liquid being trapped behind the tympanic membrane in patients with chronic suppurative otitis media is myringotomy with tubes (making a hole in the tympanic membrane and placing a drainage tube through it).
2. otosclerosis A condition of a bony labyrinth in which there is spongy bone formation in front of and behind the stapes, resulting in conductive hearing loss.
3. perforation A hole made through a part or substance. A perforated tympanic membrane is a common ear problem and most often heals without the need for surgical repair.
4. pharyngitis Inflammation of the pharynx (a sore throat).
5. presbycusis The sensorineural hearing loss which occurs as a part of normal aging.
6. rhinitis Seen most frequently in upper respiratory tract infection; this inflammation of the mucous membrane of the nose is characterized by edema and dilation of the nasal mucous membrane, nasal discharge, and nasal obstruction.
7. schwannoma An acoustic neurinoma; an enlarging, benign tumor usually within the internal auditory canal which arises from cells of the 8th cranial nerve.
8. sinusitis Inflammation of the sinuses, usually the paranasal sinuses, which may be purulent or nonpurulent. Types are named for the sinuses involved.
9. vestibular neuronitis A benign disorder which is characterized by the sudden onset of severe vertigo which is persistent at first and then becomes paroxysmal.
