CLINICAL EFFICACY OF DIFFERENT SURGICAL METHODS IN CONGENITAL PREAURICULAR FISTULA SURGERY.

Abstract

Objective: To evaluate the clinical efficacy of different surgical methods in congenital preauricular fistula surgery.

Methods: 60 patients with congenital preauricular fistula were selected and randomly divided into a microscope group of 30 cases and a macroscopic group of 30 cases. The microscope team used the fistula separation method to perform surgery along with the fistula opening. In the macroscopic group, en bloc resection was performed using the helix crus cartilage, superficial temporalis fascia and parotid capsule as boundaries. Analyze the efficacy of the two surgical methods.

Results: After more than one year of follow-up, 29 of the 30 cases in the macroscopic group were cured and 1 case improved, with wound dehiscence and scar healing occurring. All cases in the microscopy group were cured. There was no recurrence after surgery in both groups. After the chi-sqaure test, the results showed that there was no statistically significant difference between the two groups. The operation time in the naked eye group was shorter, but the postoperative incision healing in the microscopic group was more beautiful and scars were less obvious.

Conclusion: Both macroscopic en bloc resection and microscopic fistula separation can effectively cure preauricular fistula. However, the operation time in the naked eye group was shorter, while the postoperative incisions in the microscopic group were more beautiful, and the scars were less obvious.
