Abstract

Abstract: Objective: To compare postoperative curative effects of condylar fractures by anteroparotid approach and transparotid approach of retromandibular incisions. Method: This study consisted of 52 cases with condylar fractures treated at the Affiliated Stomatology Hospital of Southwest Medical University between January 2013 and June 2017. Fifty-two cases were randomly divided into modified incision group and control group. The patients of the modified incision group with condylar fractures accepted surgical treatment by the anteroparotid of retromandibular incisions, while the patients of the control group with condylar fractures accepted surgical treatment by the transparotid approach of retromandibular incisions. During the follow-up period of 6-36 months, the curative effects were evaluated based on operation time, fracture restoration, mouth opening, occlusion relationship, facial nerve injury, and salivary fistula. Results: Modified incision group: the average operation time was 79.60 min; all patients recovered well in fracture restoration, mouth opening and occlusion relationship; 1 case of temporary facial nerve injury occurred;and no case of salivary fistulas occurred. Control group: the average operation time was 86.40 min; all patients recovered well in fracture restoration, mouth opening and occlusion relationship; facial nerve injuries happened in 6 cases, 1 of which was permanent and 5 of which were temporary facial nerve injuries; 4 cases had postoperative salivary fistulas. Conclusion: Compared with the traditional transparotid approach of retromandibular incisions, the anteroparotid approach of retromandibular incisions effectively reduced the intraoperative facial nerve injury and postoperative salivary fistulas in the treatment of condylar fractures by opening reduction and internal fixation. Moreover, it shortened the operation time, and did not increase the incidence of other complications. Therefore, it was worthy of clinical expansion.
