ABSTRACT
The authors analyzed clinical manifestations and the results of surgical treatment of 204 patients with cholesteatoma in the pars tensa of the tympanic membrane. It has been established that 91.7% of cases are presented by the primary cholesteatoma in the pars tensa, among which 49.0% are the sinus cholesteatoma, and 42.6% are the cholesteatoma of pars tensa of the tympanic membrane proper. 8.3% of the group displays another mechanism of cholesteatoma generation – the secondary mesotympanal cholesteatoma associated with chronic inflammation of the middle ear with the tympanic membrane perforation and tympanosclerosis of various localization and degree. The expansion of cholesteatoma beyond the initial growth point is observed in all types of cholesteatoma. It has been revealed that the maximum degree of ossicular chain destruction is observed in sinus cholesteatoma, here the worst functional result was obtained in the secondary cholesteatoma due to auditory ossicles fixation with tympanoslerosis. The maximum frequency of the both forms of recurrent cholesteatoma – 19.5% – was noted in the cholesteatoma of pars tensa of the tympanic membrane proper, of which 8.0% was due to recurrent disease associated with persistent tubular destruction. Individual choice of surgical approach in each case of middle ear cholesteatoma, long-term postoperative observation using advanced radiological examination methods is the key to the successful treatment of this complex pathology.
