Modified Preauricular Transparotid Approach for Treating Mandibular Condylar Fractures.

AIM OF THE STUDY: We introduce a technical variant of the standard preauricular approach to treat intracapsular and condylar neck fractures: the modified preauricular transparotid approach (MPTA). The main modification, when compared with the conventional submandibular approach, is that the incision of the superficial musculoaponeurotic system is performed directly above the parotid gland, and the buccal branch of the facial nerve is dissected in a retrograde way within the parotid gland.

CASE SERIES: Between January 2019 and December 2020 at the Maxillofacial Departments of "Ospedale Maggiore" of Parma and "Policlinico San Martino" of Genoa 6 patients affected by intracapsular and condylar neck fractures underwent open reduction and internal with MPTA. Surgery was uneventful in all patients; no infections occurred in any of the cases; the mean procedure duration was 85 minutes, ranging from 75 to 115 minutes. 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.

CONCLUSION

MPTA is particularly suited for intracapsular and condylar neck fractures. Morbidity is negligible in terms of damage to the facial nerve, vascular injuries, and esthetic deformity.
