Facial nerve paralysis: a complication of distraction osteogenesis of the mandibular ramus in the treatment of temporomandibular joint ankylosis.
Distraction osteogenesis is a useful technique in temporomandibular joint reconstruction after gap arthroplasty for ankylosis. We report a case of unilateral facial nerve paralysis during the distraction phase of treatment in a patient with temporomandibular joint ankylosis who was treated with gap arthroplasty and distraction osteogenesis. The clinical course is described and discussed.
