Summary

Conchal cartilage is effective for tympanoplasty, offering good hearing outcomes and a high graft success rate. This study supports its use as a primary option in middle ear surgery.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Biomaterials in Medicine

Background:

  • Cartilage grafts have a history in middle ear surgery, previously limited by concerns over hearing outcomes.
  • Recent evidence challenges the notion that cartilage negatively impacts postoperative hearing.
  • Conchal cartilage is a viable autograft material for reconstructive middle ear procedures.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of using conchal cartilage in tympanoplasty.
  • To assess the impact of cartilage grafts on postoperative hearing in various tympanoplasty types.
  • To determine the graft take rate and revision rates associated with cartilage tympanoplasty.

Main Methods:

  • Retrospective analysis of 161 cases undergoing conchal cartilage tympanoplasty.
  • Evaluation of pure tone average air-bone gap in tympanoplasty type I.
  • Assessment of hearing outcomes when combined with ossiculoplasty (intact or absent stapes).

Main Results:

  • 88.4% of tympanoplasty type I cases achieved an air-bone gap within 20 dB.
  • 72% of cases with intact stapes and ossiculoplasty achieved closure within 20 dB.
  • 54.5% of cases with absent stapes and ossiculoplasty achieved closure within 20 dB.
  • Graft take rate was 95.6%, with 22% of cases being revisions.

Conclusions:

  • Conchal cartilage tympanoplasty demonstrates favorable hearing results and a high graft success rate.
  • The study supports the use of conchal cartilage as a primary graft material in tympanoplasty.
  • Concerns regarding detrimental effects on hearing appear unfounded based on this experience.
