Aim: To evaluate the clinical efficiency of a 2 mm lambda plate for open reduction and internal fixation (ORIF) of condylar fractures in terms of surgical time, plate adaptability, mouth opening, restoration of occlusion, and ramus height. Materials and methods: A prospective study was conducted, including 16 patients presenting with subcondylar fractures. Under general anesthesia, a surgical approach was employed, and fracture fixation was accomplished using the titanium (Ti) lambda plate of 2 mm thickness and having seven holes. Patients were postoperatively (post-op) followed up clinically and radiologically at 1 week and 1 and 3 months. Results: Plate adaptability was good. The mean surgical time was 110.5 minutes. All patients showed a statistically significant increase in mouth opening following surgery. Around 93.8% (15 patients) had occlusion, which was deranged preoperatively (pre-op). This improved significantly in the post-op period. Pre-op, seven patients (43.75%) had a deviation on the opening of the mouth, and after surgery, it significantly decreased. The variation in mean bite force at central incisor (CI), right premolar, left premolar, and right and left molar between various time intervals was statistically significant p< 0.001. Conclusion: We conclude that the use of a 2 mm seven-hole lambda plate for fractures in the subcondylar region presents a good option to achieve stable osteosynthesis with less surgical time and complications. Clinical significance: There is limited data regarding surgical management of subcondylar fractures, owing to the challenge in accessing the region and the complexity of reduction of the displaced fragments. Fixation techniques also add to the issue. Exploration of surgical management of subcondylar fractures and data on in vivo evaluation of lambda plate design will enhance the prospects and knowledge for the development and implementation of the treatment protocol.
