[On surgical strategies in the treatment of patients with chronic purulent otitis media with different nature of pathology of the middle ear].

Long-term outcomes of surgery have been analysed for 684 patients with OMCP in terms of possible implications of the severity and kind of pathological processes in the middle ear as well as the operative procedure on functional and anatomic results of tympanoplasty. Early surgical interventions in OMCP are preferable because they allow "closed" tympanoplasty. Maximal removal of hypertrophic inflammation-affected parts of the tympanic mucosa promotes functional effectiveness of the operation in view of higher position of the stapes achieved with the help of combined prostheses. The "open" variant of the operation performed because of cholesteatoma is made with maximal removal of the posterior bone wall of the external acoustic meatus in order to revise facial and tympanic sinuses and to enable better conditions for cavity to exercise postoperative self-cleaning.
