Transmasseteric anterior parotid approach for condylar fractures: experience of 129 cases

We have evaluated the transmasseteric anterior parotid (TMAP) approach in the treatment of 163 condylar fractures in 129 patients. Ninety-five patients presented with unilateral, and 34 with bilateral, fractures. The inclusion criteria were patient's choice for open reduction and internal fixation, displaced unilateral condylar fractures with occlusal derangement, and displaced bilateral condylar fractures with anterior open bite. Mean (SD) maximum interincisal opening after 3 months was 44(5)mm. There were no differences in lateral movements during the reviews 6 weeks and 3 months postoperatively. Protrusive movement at the end of 3 months was 7(2)mm. All patients achieved functional occlusion identical to the pretraumatic occlusion and good reduction of the condyles. No patient developed temporary or permanent facial palsy, sialocele, salivary fistula, or Frey syndrome. The mean (SD) operating time was 46(11)min. The TMAP approach avoids the complications of incision of the parotid gland, minimises the risk of facial nerve palsy, and offers excellent access to the fractured condyle.
