Abstract
Objective

Several surgical techniques and modifications have been described to reduce the high recurrence rate after excision of preauricular sinus (PAS). This study was designed to evaluate the surgical outcomes of PAS excision using a new modified supra-auricular approach (SAA) and to assess the predisposing factors for recurrence.

Methods

A total of 175 (158 patients) PAS excision procedures were performed from 2007 to 2016 in a single institute using this modified SAA with helix cartilage suture to obliterate the dead space. The specimens were assessed to measure the closest distance between the squamous tract and the excised auricular cartilage (sinocartilaginous distance). We also evaluated the surgical outcomes and investigated the predisposing factors for recurrence, including gender, lesion laterality, etiology (primary or revised), anesthesia methods (general or local), history of infection, and history of incision and drainage (I&D) for abscess.

Results

Patients were followed up for a median duration of 45 months (range from 6 months to 10 years). There was a 2.3% (4 ears) recurrence rate and a 1.7% (3 ears) complication rate in our series. The average sinocartilaginous distance was 0.44 mm (median distance, 0.3 mm) and this value was less than 0.5 mm in 66% of cases. Recurrence was not significantly affected by gender, lesion laterality, etiology of surgery, anesthesia method, or a history of infection or preoperative I&D for abscess.

Conclusions

Surgical PAS excision using the modified SAA with cartilage suture of dead space yielded low overall recurrence and complication rates in this series. Cosmesis was maintained due to a smaller incision. No significant predisposing factors for recurrence were identified. Thus, the modified technique described in the present study can be regarded as a simple, effective and reproducible surgical treatment for PAS.
