[Myringoplasty and its effect on a vestibular function in patients with otitis media purulenta chronica (OMPC)].

A complex vestibulologic and audiologic examination was made in 25 patients with OMPC free of mesotympanitis before and after experimental myringoplasty with hen's egg amnion. The patients were divided into two groups depending on the presence of vestibular complaints. Partial or complete disappearance of subjective vestibular symptoms, reduced stimulation of the vestibular receptors (by 19%, on the average) were detected by experimental vestibular tests on the side of the affected ear. The asymmetry coefficient by labyrinth lowered by 31.1%, on the average.
