Analysis of the High Submandibular Approach: A Critical Reapprasail of a Transfacial Access to the Mandibular Skeleton.

Abstract

In 2006 following the development of dedicated osteosynthesis plates, Meyer and colleagues reported a successful clinical study of condylar fractures treated by a modified submandibular approach; it was called high submandibular approach or "Strasbourg approach." The aim of this study is to describe the high submandibular approach step by step. Between January 2010 and December 2015 at the Maxillofacial Unit of the Hospital "Policlinico San Martino" 13 patients affected by subcondylar fracture underwent open reduction and internal with high submandibular approach. Surgery was uneventful in all patients; no infections occurred in any of the cases; the mean procedure duration was 89 minutes, ranging from 66 to 125 minutes. The mean hospital stay was 2.9 days, ranging from 2 to 6 days. At the 1-year follow-up, all patients had stable occlusion with a natural, well-balanced morphology of the face and adequate dynamic excursion of the mandible. The morbidity is negligible in terms of damage to the facial nerve, vascular injuries, and aesthetic deformity. The authors think that further prospective clinical trials are necessary to assess and eventually develop this approach.
