[Sanation surgery for the treatment of chronic suppurative otitis media with cholesteatoma].

Results of the surgical treatment of 98 patients presenting with chronic suppurative otitis media (CSOM) and accompanying cholesteatoma. CSOM of large duration turned out to be associated with cholesteatoma in 31.3% of the patients regardless of localization of the tympanic defect. A variety of surgical interventions were undertaken depending on the extension of cholesteatoma including the intrameatal approach (n=75), endaural approach (n=16), postaural approach (n=6), and the combined approach (n=1). Forty two patients presenting with either central or peripheral peroration in the strained part of the tympanic membrane were operated with the use of the intrameatal approach. Perforation in the unstrained part of the tympanic membrane in 56 patients with chronic suppurative otitis media and cholesteatoma extending to the antrum and the cells of the mastoid process was corrected by sanation operation at different stages of the carious process using different surgical approaches. The early surgical intervention during the carious process in the patients presenting with CSOM and cholesteatoma in the phase of remission, taking into account structural peculiarities of the mastoid process and distribution of the inflammatory process, significantly reduced its extension and permitted to reconstruct the structure of the middle ear in 70% of the patients.
