ABSTRACT
OBJECTIVE: To introduce a new method of preauricular fistula resection and discuss its clinical efficacy. METHODS: Clinical data of 40 patients with 40 classical preauricular fistulas in our hospital were collected. The patients comprised of 19 male and 21 female patients aged 3-60 years. The fistula and part of the related cartilage were completely removed by a concealed incision on the inner side of the auricular crus, and the opening of the fistula was retained. The postoperative efficacy was analyzed. RESULTS: The operation time ranged from 15 to 30 minutes (mean, 25 minutes), and the blood loss ranged from 4 to 8 mL (mean, 5 mL). After complete fistula resection, the wound was closed with interrupted sutures. Dressing changes started 2 days after surgery and performed once a day, and the wound sutures were removed 7 days after surgery. All patients were followed up for 6 to 12 months (mean, 8.7 months) after surgery. Except for one patient with mild wound pain after suture removal, no patients developed infection or recurrence. CONCLUSION: Use of a concealed surgical incision for treatment of a classical preauricular fistula has good results. There is no obvious scar on the ear after surgery and the procedure does not affect the facial appearance. It not only completely removes the lesion but also meets the patient's esthetic needs.
