Osteochondroma of the mandibular condyle treated by modified Nam's method: Report of a case

Abstract

We presented a case of osteochondroma of the mandibular condyle treated by modified Nam's method. A 24-year-old woman was referred complaining of progressive facial asymmetry and malocclusion. Clinical examination revealed the deviation of the mandible to the right, and cross bite on the contralateral side. Preoperative panoramic radiograph and CT scans demonstrated the bony protuberance arising from the anteromedial surface of the left condyle. Hot area was observed in the left condyle in RI examination. Exposure of the condyle and tumor was done via a submandibular approach. A vertical osteotomy was performed from the sigmoid notch to the angle, posterior border of the mandibular ramus was removed from the wound. After resection of the tumor and reshaping of the condyle, osteotomied segment with residual condyle was replaced. Specimen was pathologically diagnosed as osteochondroma. 4 weeks of maxillomandibular fixation was followed by functional physiotherapies. Her clinical course has been favourable with an excellent aesthetic and functional recovery 6 years postoperatively.
