Single-stage autologous ear reconstruction for microtia

Area of Science:

• Plastic Surgery
• Otolaryngology
• Regenerative Medicine

Background:

• The Nagata technique for ear reconstruction has been utilized since 2002.
• This review examines 100 consecutive ear reconstructions using modified Nagata techniques.
• Evolved modifications enhance auricular contour and enable single-stage reconstruction.

Purpose of the Study:

• To present modifications of the Nagata technique for autologous ear reconstruction.
• To evaluate the effectiveness of these modifications in improving auricular contour.
• To demonstrate the feasibility of single-stage auricular reconstruction for microtia.

Main Methods:

• Retrospective review of a prospectively acquired database of primary congenital microtia reconstructions.
• Analysis of 100 consecutive ear reconstructions performed between 2002 and the present.
• Photographic documentation of 10 representative cases to illustrate technique and outcomes.

Main Results:

• A shift towards single-stage reconstructions was observed, with 51 ears reconstructed using Nagata stage I or single-stage procedures.
• Two-stage reconstructions were performed in 24 ears, with a complication rate of 22%.
• In the last 40 reconstructions after abandoning the two-stage approach, the complication rate decreased to 15%.

Conclusions:

• Modified Nagata technique provides improved auricular contour and projection.
• Single-stage reconstruction is achievable with modifications addressing the inferior crus and tragal position.
• The technique modifications result in better aesthetic outcomes and reduced surgical complications.
