Three-point fix tympanoplasty

Conclusion: The three-point fix tympanoplasty procedure is a stable and effective technique - with a high degree of graft take and satisfactory hearing results - for reconstruction of most tympanic membrane (TM) perforations. Objective: It is difficult to repair a TM perforation, including subtotal perforation, involving the anterior part of the annulus. Reperforation can occur when an underlay graft technique is used. An overlay graft technique may result in anterior blunting/lateralization. We introduce a three-point fix tympanoplasty procedure, which can provide additional support to yield a stable graft. Methods: The study enrolled a total of 234 patients who underwent a three-point fix tympanoplasty procedure from November 2005 to June 2011. Anatomic success was defined as an intact, repaired TM, while functional success was defined as a significant decrease in the air - bone gap at the end of follow-up compared with preoperative hearing (air - bone gap). The complication rate was also analyzed. Results: The anatomic success rate was 93.2% (218/234 patients). The functional success rate after an average of 1 year was 73.5%. The postoperative average pure-tone air - bone gap (15.4 ± 11.4 dB) decreased successfully in comparison with the preoperative average air - bone gap (20.6 ± 12.1 dB). There were few postoperative complications (7.7%).
