This study aimed to classify the pre-auricular sinus before performing radical dissection, so as to achieve optimal aesthetic results.
The 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.
All 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.
Surgical 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.
