Supra-auricular and post-auricular resection of pre-auricular and post-auricular sinuses

Abstract

ObjectiveThis study aimed to classify the pre-auricular sinus before performing radical dissection, so as to achieve optimal aesthetic results.MethodsThe recent five-year clinical data of 53 patients with a congenital pre-auricular sinus and infection treated in the hospital were reviewed. According to the sinus course, pre-auricular and post-auricular types were defined, and regional dissection was performed using the modified supra-auricular or post-auricular approach.ResultsAll patients achieved primary intention healing of the incision, and were followed up for six months to five years. No recurrence was found, and the incision scar was completely concealed.ConclusionSurgical approaches for regional dissection might be adopted based on the different types of pre-auricular sinuses, and further radical dissection might be performed to achieve optimal aesthetic results.

Variant Types of Preauricular Sinuses: Classifications, Clinical Presentation and Management

“…4 Ding et al reported on the pits of two ears (2/53, or 3.8%) which were located in the crus of the helix, and 51 ears which had pits in the anterior portion of the helix. 9 In our study, variant preauricular sinuses accounted for 6.7% of all preauricular sinuses, a similar rate to that of Yeo et al…”

“…In this study, the fistula locations included the ascending helix crus (15 ears, most common), the infra‐auricular area (3 ears), the supra‐auricular area (1 ear), and anterior to tragus (1 ear) 4 .
