inflammation. Chronic otitis media • Usually results from recurrent acute otitis media and eustachian tube dysfunction, but may also be due to trauma or other diseases • Involves permanent perfor ... ation of the tympanic membrane, with or without recurrent pus formation • Often accompanied by changes in the mucosa and bony structures (ossicles) of the middle ear • May lead to formation of a cholesteatoma (non-cancerous cyst or mass that contains epithelial cell debris), which can cause conductive hearing loss • Incidence of cholesteatoma is highest in children and young adults. • Treatment may include surgical repair of the perforated tympanic membrane (tympanoplasty) to restore sound conduction and the integrity of the middle ear or surgical removal of cholesteatoma 2 Symptoms Acute otitis media: • Mild to severe pain in the affected ear • Fever • Diminished hearing • Dizziness • Vertigo • Tinnitus • Pus in the mastoid air cells often causes mastoid tenderness. • Tympanometry or air insufflation (blowing air into the ear) may reveal decreased movement of the tympanic membrane. • Tympanic membrane rupture, or perforation, may release a purulent discharge. • Myringotomy (surgical incision of the tympanic membrane) may be performed to relieve the pressure. Recurrent acute otitis media: • Refers to repeated incidences of acute otitis media, such as three in 6 months or four in 12 months. Serous otitis media: • Fluid in the middle ear without inflammation • Reported sensation of “snapping” or “popping” and acute hearing loss in the affected ear • May cause severe vertigo (sensation of whirling or rotation) • Sometimes becomes chronic (continuing for more than 3 months) and is more often linked to development of sensory hearing loss Risk Factors Otitis media occurs more frequently during winter months. Certain factors may increase a [Show More]
