Abstract
[Astract]Objectives To evaluate acoustic effect after canal wall-down tympanoplasty with section of the tensor tym-pani muscle(TTM) tendon in patients with chronic otitis media on long-term follow-up.Materials and Methods From Janu-ary 2010 to june 2014, 76 patients underwent canal wall-down tympanoplasty with ossicular chain reconstruction in a 1-stage surgery. For this study, the patients were assigned into two groups. In group 1(36 patients), the TTM tensor would be removed during the surgery while it would be retained in group 2(40 patients).Pre-and postoperative air and bone conduc-tion (AC, BC) thresholds at 0.5, 1, 2, and 4 kHz were reported and the air-bone gaps were measured.Results Mean postop-erative AC and air–bone gap was 35.9±13.6dB and 13.5±5.9dB in Group 1 . While Mean postoperative AC and air–bone gap was 34.7±13.0dB and 14.8±4.8dB in Group 2. Both were not statistically different (P>0.05). 88.9%of patients in Group 1 and 90.0%of patients in Group 2 attained a postoperative air–bone gap of 20 dB or less, not statistically different (P>0.05). Conclusion Section of the tensor tympani muscle tendon in canal wall-down tympanoplasty with ossiculoplasty had no statistically significant influence on sound transmission long-term follow-up and can be a safe maneuver in middle-ear surgery.关键词
