title: The retromandibular transparotid approach to mandibular subcondylar fractures.
abstract: The aim of this study was to evaluate the safety, utility and morbidity associated with the treatment of mandibular subcondylar fractures using the retromandibular transparotid approach and to evaluate the stability of a single 2mm miniplate fixation system for such fractures. Forty-two cases with 48 mandibular subcondylar fractures were analysed prospectively for 12 months and evaluated for functional results, scar, postoperative complications and stability of fixation. There were three cases of suboptimal occlusal status, two cases of haematoma that were drained and resolved, eight patients with facial nerve weakness which resolved in a few weeks, and three cases of salivary fistulae that resolved after treatment. All cases showed stable osteosyntheses. Maximal postoperative interincisal distance was 32-61 mm (mean 44 mm). Four patients had deflection on opening, while clicking on opening or chewing was observed in five patients. The postoperative scars were well accepted by all patients. The results of this study suggest that a retromandibular approach will facilitate accurate reduction and fixation of subcondylar fragments with a good cosmetic result and minimal complications. A single 2 mm miniplate fixation provides stable results.
