Analysis for different functional results of TMJ ankylosis management by comparing ramus-condyle unit reconstruction using vertical ramus osteotomy and interpositional gap arthroplasty

Coronoidectomy, condylectomy, and free vascularized fibula osteomusculocutaneous flap transfer for severe trismus due to contracture of the oral mucosa and temporomandibular joint ankylosis after maxillectomy: A case report

“…It can also result in facial disfigurement that may induce psychological stress and reduce quality of life (Kaban et al, 2009). Treatment of TMJ ankylosis includes release of the ankylosis, and creation of a gap with or without interpositional insertion of autologous material (Chossegros et al, 1997;Gupta & Sen, 2021). In our case, the cause of trismus includes not only the contracture of mucosa but also the TMJ ankylosis.…”

“…In severe cases, coronidectomy or reconstruction using vascularized tissue transfer may be needed at the same time (Fu-Chan et al, 2021;Chang et al, 2004). The treatment of trismus due to ankylosis of the temporomandibular joint (TMJ), which is a distressing structural condition identified by loss of jaw movement due to formation of fibrous or osseous accumulations fused to the skull base, includes release of the ankylosis (Gupta & Sen, 2021).…”

Reankylosis of temporomandibular joint 5 years after interpositional arthroplasty using gold foil: management and follow up (a case report)

“…The surgical technique used may also become a triggering factor of reankylosis. The author did a literature analysis ( Table 1 ) and concluded that using interpositional material has a lower risk of reankylosis than performing gap arthroplasty only [ 4 , [11] , [12] , [13] , [14] ].…”
