Introduction: the therapeutic handling of the temporomandibular ankylosis has included different surgical modalities. Objective: this study was done with the objectives: to characterize the treated sample social- demographically, to identify associated causes, to classify ankylosis topographically and according to Shawhney´s Classification, to determine the values of maximum buccal opening and mandibular trajectories before and after treatment. Material and methods: a case series study was carried out in 14 patients of the total of patients with ankylosis diagnosis who attended to the Maxillofacial Departament, in the University Hospitals "Miguel Enríquez", "Salvador Allende" and Dentistry College "Raul González Sánchez", between 2002-2011. The sample was subjected to surgical treatment with arthrolysis, and interposition of temporalis fascial flap. The studied variables were: demographical, causes, types of ankylosis, maximum buccal opening and mandibular trajectories, accidents and complications. Results: patients among 22-31 years (57,2%), masculine sex (71,4%), traumatic causes with condylar fractures (71,4%), and bilateral ankylosis(71,4%). The average value of maximum buccal opening was before treatment (8 mms) and after 12 months (39 mms). Conclusions: the Interpositional arthroplasty with temporalis fascial flap restored the normal values of mandibular movements in the totality of the studied sample, with stable results.
