The three-point fix tympanoplasty is a successful surgical technique for repairing tympanic membrane (TM) perforations. This method offers high graft success rates and improved hearing outcomes for patients.

Area of Science:

  • Otolaryngology
  • Surgical Innovation

Background:

  • Tympanic membrane (TM) perforations, especially subtotal ones involving the anterior annulus, present repair challenges.
  • Traditional underlay techniques risk reperforation, while overlay methods may cause anterior blunting or lateralization.

Purpose of the Study:

  • To introduce and evaluate the efficacy of a novel three-point fix tympanoplasty procedure.
  • To provide enhanced graft support for improved stability in TM perforation repair.

Main Methods:

  • A prospective study included 234 patients undergoing the three-point fix tympanoplasty from November 2005 to June 2011.
  • Anatomic success was defined as a healed TM, and functional success by reduction in air-bone gap.
  • Complication rates were systematically analyzed.

Main Results:

  • High anatomic success rate of 93.2% (218/234 patients) was achieved.
  • Functional success, measured by decreased air-bone gap, was 73.5% after one year.
  • The average air-bone gap improved from 20.6 dB preoperatively to 15.4 dB postoperatively, with a low complication rate of 7.7%.

Conclusions:

  • The three-point fix tympanoplasty is a stable and effective surgical technique.
  • It demonstrates high graft take rates and satisfactory hearing results for various tympanic membrane perforations.
  • This procedure offers a reliable solution for challenging TM perforations.
