A new supra-auricular incision technique for auricular reconstruction in microtia patients improves cosmetic and functional outcomes. This method offers clinical advantages over traditional approaches for ear reconstruction.

Area of Science:

Plastic Surgery
Craniofacial Surgery
Regenerative Medicine

Background:

Microtia is a common congenital craniofacial malformation requiring surgical correction.
Auricular reconstruction using tissue expansion is a standard treatment.
This study evaluates a novel supra-auricular incision for the second stage of single-flap auricular reconstruction.

Purpose of the Study:

To compare the outcomes of a novel supra-auricular incision versus a conventional retro-auricular incision in the second stage of single-flap auricular reconstruction for microtia.
To assess the esthetic and functional results, patient satisfaction, and complication rates of the new technique.

Main Methods:

Retrospective analysis of 86 patients with unilateral microtia undergoing two-stage single-flap auricular reconstruction.

Keywords:

Cranioauricular angle Ear reconstruction Expanded skin flap Microtia

Patients were divided into two groups: Group A (40 patients, conventional retro-auricular incision) and Group B (46 patients, novel supra-auricular incision).

Outcomes including cranioauricular angle, subunit appearance, functional assessments (glasses/mask wear), patient satisfaction, and complications were evaluated.

Main Results:

The supra-auricular incision group (Group B) showed significantly improved cranioauricular angles compared to the retro-auricular incision group (Group A) (p < 0.001).
Enhanced appearance of auricular subunits (helix, scapha) and improved functional outcomes, particularly in glasses and mask wear, were noted in Group B.
Group B reported higher patient satisfaction scores and experienced fewer complications, such as flap necrosis and hypertrophic scarring, compared to Group A.

Conclusions:

The novel supra-auricular incision technique for auricular scaffold placement in the second stage of single-flap auricular reconstruction yields superior esthetic and functional results.
This approach demonstrates clinical superiority and broader applicability compared to conventional methods in microtia reconstruction.
The supra-auricular incision is a promising advancement in auricular reconstruction surgery.
