Comparative Evaluation of Modified Tragus Edge Approach and Retromandibular Approach to Mid- or Low-Level Mandibular Condylar Fractures.

Objectives: To compare and evaluate the modified tragus edge approach (MTEA) with retromandibular approach for surgical access to mid-level or low-level mandibular condylar fractures. Materials and
Methods: This study comprised of 22 patients with mid-level or low-level condylar fracture. Patients with clinical and radiological evidence of mid-level or low-level condylar fracture are included only in this study. Patients were randomly divided into two groups: group A includes 11 patients, in which modified tragus edge approach was used, and group B includes 11 patients treated with retromandibular approach. Patients were evaluated clinically after first week, second week, fourth week, third month, and sixth month radiographically.
Results: The mean age of the study subjects in group A was 32.45 ± 8.98 years, while in group B, the mean age was 26.91 ± 5.79 years. Post-operatively, no significant difference was seen in relation to pain, occlusal relationship, mouth opening, and deviation of jaw during opening and closing movements. In terms of post-operative complication, only significant difference found between two groups is post-operative scar visibility, which is higher in retromandibular incision group as compared to MTEA.
Conclusion: Thus, we can conclude that MTEA provides ease of operation as a good exposure of mandibular mid- or low-level condylar fracture as retromandibular approach but with less visibility of post-operative scar as compared to retromandibular approach. © The Association of Oral and Maxillofacial Surgeons of India 2020.
