[A closed variant of staged tympanoplasty with mastoidectomy in patients with chronic purulent otitis media].

127 case records were analysed retrospectively. All the patients had otitis media purulenta chronica and had undergone tympanoplasty (a closed variant). Regular revision of the trepanation cavity was performed in patients with cholesteatoma. Residual cholesteatoma was detected in 5 of 76 patients with cholesteatoma before the first operation, recurrent cholesteatoma occurred in 2 patients. Normal position of the neotympanic membrane and recovery of normal anatomy of the external acoustic meatus were achieved in 116 (91.3%) operated patients. Preservation or improvement of hearing were observed in all the patients. Bone-air gap under 30 dB was obtained in 79%. Thus, the proposed variant of closed staged tympanoplasty is effective for sanation of the infection focus with subsequent hearing improvement.
