Trans-Tragal Approach for Mandibular Neck and Head Condylar Fractures.

Abstract

This retrospective observational study evaluates the trans-tragal approach for the treatment of mandibular head and neck condylar fractures. From January 2009 to May 2024, 34 patients (20 males, 14 females, mean age 34 years) with 36 condylar fractures were treated using this approach. Surgical outcomes were assessed based on occlusal relationship, maximum mouth opening, and facial nerve function (House-Brackmann scale). Postoperative imaging included computed tomography scans, with follow-ups at 1, 3, 6 months, and 1 year. Complications such as wound infection, hematoma, and salivary fistula were also evaluated. Results showed satisfactory postoperative outcomes, with 32 patients maintaining normal occlusion and a mean interincisal opening distance of 40 mm. Three patients experienced complications, including temporary facial nerve numbness in one case, with complete recovery in 2 weeks, and 2 cases requiring reoperation due to condylar segment displacement. No cases of permanent facial nerve damage, salivary fistula, or tragal cartilage necrosis were observed. Aesthetic outcomes were satisfactory, with scars hidden in natural folds. The trans-tragal approach provides adequate surgical exposure to the posterior condylar region while minimizing the risk of facial nerve injury. Although the results of this study indicate favorable outcomes, further randomized controlled studies are required to validate these findings due to the non-randomized design and small sample size.
