Open reduction-fixation of mandibular subcondylar fractures. A review.
From 1973 to 1990, 392 mandibular subcondylar fractures were treated at the University of California, Davis, by the Otolaryngology Department. Of these, 17% were handled by open reduction and internal fixation. Twenty-one patients from this group were located for follow-up at an average interval of 64 months. Retrospective review shows the operation to be safe, with few complications and no permanent sequelae. Patient examination often revealed abnormalities of occlusion and mandibular function; however, these objective findings did not correlate well with patients' relative lack of subjective complaints. An 86% incidence of roentgenographic evidence of condylar disease after open reduction and internal fixation was found. We question the long-term efficacy of open reduction and internal fixation in restoring fracture alignment and maintaining mandibular height given the high rate (86%) of condylar disease in our patient population.
