Modified Tragus Edge and Transmasseteric Anteroparotid Approach for Intracapsular and Condylar Neck Fractures.

The aim of this study was to evaluate the effects of protecting the facial nerve and reducing the scar visibility using a modified tragus edge and transmasseteric anteroparotid approach compared to classic preauricular approach for intracapsular and condylar neck fractures. This retrospective study included 64 patients (78 sides) who underwent surgical treatment for intracapsular or condylar neck fractures from January 2014 to June 2018. Patients were divided into the experimental group (treated via a modified tragus edge and transmasseteric anteroparotid approach), and the control group (treated via the classical preauricular approach). Therapeutic outcome assessment parameters included facial nerve injury, salivary fistulae, wound infection, restricted mouth opening, postoperative occlusion disorders, and scar visibility. In the control group, there were 3 cases of facial nerve injuries and 2 cases of salivary fistulae. One case of temporary facial nerve injury occurred in the experimental group, with complete recovery within 1 month. The scars were less visible in the experimental group than in the control group. These results suggest that a modified tragus edge and transmasseteric anteroparotid approach reduced the incidences of facial nerve injuries, minimized the scar visibility, improved exposure of the operative site and fixation of titanium screws or plates, and did not increase the frequency of other complications.
