Dani, Dr. A. KHAIRI, Dr O. Bouanani, Dr Z. Sayad, Pr M. Boulaadas Abstract: Introduction: Temporomandibular ankylosis is defined as a permanent constriction of the jaws with a mouth opening of less than 30 mm. It can be uni or bilateral. The aetiologies are dominated by the traumatic origin, the infectious origin is the rarest. The treatment is surgical, several techniques are used. Patients and methods: This is a retrospective study of cases collected at the department of maxillofacial surgery and stomatology of the IBN SINA university hospital in Rabat-MOROCCO. It covers the period between January 2014-December 2018. All of our patients treated for intra-articular temporomandibular ankylosis underwent a surgery of resection with interposition of a costal cartilage graft. Results: No cases of recurrence were observed during the postoperative follow-up of our patients, with a follow-up of at least 1 year. Discussion: Temporomandibular ankylosis is a quite common condition, especially in developing countries. The origin of temporomandibular ankylosis is dominated by trauma. The management of this condition is difficult, several surgical techniques have been described in the literature and the results are different from one team to another.
