[Spheno-mandibular ankylosis. A case].
A rare case of spheno-mandibular ankylosis is reported in a 12 year-old child. The patient only complained of a restricted mouth opening; no particular etiologic factors were found to explain what was perhaps a myositis ossificans of the pterygoid muscles. However, neither the anatomic presentation at surgery, nor the histologic findings could confirm this diagnosis. An intra-oral route was chosen for the ankylosis resection, and the reconstruction of the resected upper part of the ramus was performed by a costo-chondral graft. The patient was free of recurrence 3 years after follow up.
