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.
