[Surgical treatment of mesotympanitis]

A chronic sluggish suppuration in the middle ear, mesotympanitis, leads to impairment of sound conduction and onset of hypoacusis. Otogenic labyrinthopathy is also possible. As to complications, present-day course of mesotympanitis is close to epitympanitis. Intensive conservative therapy should be followed by revision of the middle ear system earlier than 4-6 months of remission. In minor lesions tympanoplasty with retroauricular drainage of the antrum is indicated, in serious affection surgical intervention is needed.
