Abstract:
Objective To evaluate the effect of attic obliteration in canal wall down tympanoplasty.Methods A clinical study was performed on 100 ears with chronic otitis media that underwent open-cavity operation and attic obliteration with bone pate in Department of Otology and Skull Base Surgery of Eye and ENT Hospital form January 2010 to January 2015.A pre-and post-operative pure tone air conduction (AC) and bone conduction (BC2) audiogram were obtained 6 months after the surgery.Results There were 1 case with retraction pocket formation and 5 cases with cavity infection in the postoperative follow-up of 1 year to 5 years.The mean preoperative AC threshold of 43.2±2.3 dB HL was lowered to 29.8±1.7 dB HL postoperatively (P＜0.01).The mean preand post-operative air-bone gap was reduced with 10.6±0.5 dB (P＜0.01).Conclusion The attic obliteration with bone pate in open-cavity tympanoplasty prevents the recurrence of cholesteatoma and improves the hearing on condition that total elimination of the lesions.
