Summary

The flap pocket method for auricular reconstruction in microtia offers higher patient satisfaction and fewer complications than the expansion method. This technique also significantly reduces the overall treatment duration for patients.

Area of Science:

  • Plastic Surgery
  • Otolaryngology
  • Regenerative Medicine

Background:

  • Auricular reconstruction is essential for treating external ear deformities.
  • Current methods include the flap pocket and expansion techniques for microtia.
  • Objective comparative data on these techniques has been limited, creating controversy.

Purpose of the Study:

  • To compare the efficacy and safety of the flap pocket method versus the expansion method for auricular reconstruction in microtia.
  • To evaluate patient convenience, complication rates, and postoperative satisfaction.
  • To provide objective evidence to resolve the controversy surrounding these surgical techniques.

Main Methods:

  • A systematic literature search was conducted on PubMed, Embase, Web of Science, and Cochrane Library databases.
  • Clinical studies on auricular reconstruction in microtia published up to January 1, 2021, were included.
  • A meta-analysis was performed to synthesize data on key outcomes.

Main Results:

  • Twenty-two studies involving 7963 patients were analyzed.
  • The flap pocket method showed higher patient satisfaction (90.5% vs. 83.3%) and lower complication rates (6.8% vs. 9.5%).
  • The flap pocket method had a significantly shorter treatment period (5.57 months vs. 10.75 months) and no expander-related complications.

Conclusions:

  • The flap pocket method is superior to the expansion method for auricular reconstruction in microtia.
  • It results in greater patient satisfaction, fewer complications, and a shorter treatment duration.
  • This meta-analysis provides strong evidence supporting the flap pocket method.
