[Diagnosis and management of unilateral temporomandibular ankylosis].

INTRODUCTION: Temporomandibular joint ankylosis is defined as permanent jaw constriction with an interincisal mouth opening of less than 30 mm, due to bony, fibro-osseous or fibrous fusion. Ankylosis may be uni- or bilateral. The complications of this ankylosis affect the functions of mastication, swallowing and phonation, sometimes facial morphology, and disturb dental hygiene. The aetiologies are, in order of frequency, post-traumatic, infectious, inflammatory and congenital.

MATERIAL AND METHODS: The authors present an algorithm for the management of temporomandibular ankylosis. Management is always surgical, with at least resection of the ankylosis mass and bilateral coronoidectomy. Additional procedures are performed depending on the presence of dental articulation disorders, age and loss of ramus height. Early, aggressive and prolonged post-operative rehabilitation is essential to ensure that the mouth remains open and that there is no recurrence.

CONCLUSION: This complex pathology needs to be well understood in order to make a precise diagnosis and offer appropriate treatment.
