Abstract

Background:

Stahl ear, a rare congenital auricular anomaly, occurs when a third crus crosses the scaphoid fossa. Optimal elimination of the third crus and reconstruction the superior crus in type 1 Stahl ear remain undercharacterized. We present a novel 3-step technique to reliably correct a type 1 Stahl ear as a case report.

Methods:

A 10-year-old male with bilateral prominent type 1 Stahl ears is presented. An anterior curvilinear helical fold incision and posterior V wedge excision was used for exposure. Step 1, the third crus cartilage was excised as a full-thickness wedge and the gap approximated with posteriorly everting horizontal mattress sutures to create a flattened scaphoid fossa. Step 2, the superior crus was created using anteriorly placed horizontal mattress sutures for direct shaping. Step 3, the skin was redraped without excess trimming to minimize the visible scar.

Results:

The 3-step approach effectively eliminated the third crura and recreated the superior crura of the type 1 Stahl ears, and resulted in minimal visible anterior scarring.

Discussion:

The anterior approach provided excellent visualization and permitted tactical suture placement. The wedge excisions successfully removed the third crura. The horizontal mattress sutures to flatten the scaphoid fossa, enhance the natural antihelical curves, and form the superior crura were simple and effective.
