The aim of this study was to evaluate and report a modified tragus edge approach (MTEA) for surgical access to mid-level or low condylar fractures. The MTEA was used on 45 patients (59 sides). All of the patients were reviewed for scarring, parotid fistula, facial nerve function, occlusion, deviation, and limitation of mouth opening (MO). Forty-one patients (64 sides) with middle or low level condylar fractures who underwent surgery by retromandibular approach during the same period were selected for comparison. In the MTEA group, scars were not obvious and there was no parotid fistula. The occlusion of four cases (8.9%) was not ideal, but returned to normal after 2 weeks of intermaxillary traction. Temporary facial nerve damage was present on two sides (3.4%). MO was not deviated in any patient, but was limited in the first 2 weeks after operation in three cases (6.7%). The risks of facial nerve dysfunction and parotid fistula were much higher in the retromandibular approach group than in the MTEA group, while the risks of malocclusion and limitation of MO were similar. MTEA is safe and has good aesthetic outcomes. MTEA represents an appropriate surgical access to mid-level and low condylar fractures.
