ABSTRACT
Temporomandibular joint ankylosis is one of the most significant disorders of the stomatognathic system because it causes pain associated with severe functional limitations, such as difficulty in chewing and psychological and clinical problems due to poor oral hygiene. These disorders are quite significant in children, since the treatment is even more complex due to the fact that the condylar region is a site of active growth. The earlier the diagnosis is established, the better the treatment prognosis. Ankylosis can be treated by interposition arthroplasty of the temporalis muscle fascia in conjunction with ipsilateral coronoidectomy. The purpose of the present study was to report a clinical case of temporomandibular joint ankylosis in a pediatric patient treated by interposition arthroplasty of the temporalis muscle fascia associated with coronoidectomy.
