3. myringotomy is indicated when there is bulging of the drumhead and pain not quickly relived by antibiotics Myringotomy is usually performed to drain pus from the ear in patients with ASOM or to release serum from the middle ear in patients with secretory media

CSOM OR COM Neglected or recurrent infection of the middle ear may eventually produce a chronic change in the mucosa of the ear or destruction of the periosteum covering the ossicles, The infection then tends to become chronic Chronic infection of the middle ear is much more common in persons who had ear disease in early children. Disease of the ear in infancy and early children may arrest the normal pneumatization of the mastoid. It is possible that the same process alters the mucosa of the middle ear. so that it is more susceptible to recurrent infection than is the normal ear

Aetiology and pathology 1.Bacteriology: characteristic of the bacteriology of chronic otitis media is a shift towards a predominance of gram negative bacilli, most frequently isolated bacteria include Pseudomonas aeruginosa, staphylococcus, proteus and corynebacterium

2. t is also known that chronic infection occurs predominantly in nonpneumatizd clefts. Here it must be said that there is a difference opinion, some authorities holding that failed pneumatization is a result of infection and not a precondition 3. The prevalence of CSOM is related to social conditions
