[One-stage surgical treatment of temporo-mandibular ankylosis and its facial deformity].

A patient with temporomandibular ankylosis was treated by resection of the ankylosed block followed by lengthening of the ascending ramus by an endoprosthesis. The place of the latter in the treatment of such lesions and the deformities that result from them is analyzed. Emphasis is laid on the value of displacement of the superior arch by a Le Fort I osteotomy in the correction of facial asymmetry in cases of laterognathia due to a mandibular development defect.
