Особенности диагностики и современного хирургического лечения острого среднего отита с выпотом

Abstract

The study involved 172 patients with acute exudative otitis media treated at the period of 2013 through 2016. All the patients underwent a complex examination, systemic and local conservative therapy. The examination of the results of the temporal bones computer tomography was conducted to assess the eardrum thickness, which was significantly increased in an acute inflammatory process in the middle ear due to the thickening of the tympanic cavity mucous membrane. The values ranged from 0.2 mm to 0.9 mm (the normal thickness of the eardrum is 0.1 mm). In the absence of positive dynamics in the clinical picture and according to the results of objective examination, the surgical treatment – CO2-laser myringotomy – was performed. On average, in 12–14 days after surgery, most patients reported of hearing restoration in the affected ear, which, as a rule, coincided with the eardrum integrity restoration period. The average time of closure of a 1.2 mm eardrum perforation was 7 days, of 1.6 mm – 12 days, of 2.0 mm – 14 days. In the patients with eardrum thickness equal to or less than 0.5 mm, the complete restoration of the eardrum integrity took place on average in 11 days. In the patients with the eardrum thickness above 0.5 mm, the complete restoration of the eardrum integrity took place on average in 14 days.
