abstract: We courried out a retrospective study of 52 surgical cases of temporomandibular joint ankylosis, fibrous types I and II in 19 patients (36.4%) and osseous type III-IV in 33 patients (63.6%). Forty two children and teenagers at the Hospital de Pediatria (1983-1985/1989-1998) and Hospital General La Raza (1985-1989) were included also, 10 adults including those operated on at the Hospital de Especialidades, CMN Siglo XXI (IMSS) from 1998 to 2001 were included. We used Dunn modified method en 37 cases (67%) and 17 patients were with Risdon operated on technique (33%). Etiology of ankylosis were direct trauma to jaw, which affected temporomandibular joint mainly in children, while in adults causes were more varied and included as osteomyelitis, middle ear infection, sequels of hemifacial microsomy, and trauma results were considered as good upon obtaining mouth opening of 35 mm without neo-ankylosis during 1-year postoperative control.
