Intraoral approach for arthroplasty for correction of TMJ ankylosis

Gap arthroplasty of temporomandibular joint ankylosis by transoral access: a case series

“…Although many authors in the past have described an intraoral approach to the condyles to treat the various problems related to these, 17,18 it was Ko et al 7 who first published this technique to treat TMJ ankylosis. The authors of the current article observed similar advantages and disadvantages with their technique as described by Ko et al The advantages include the absence of a facial scar, less possibility of injuring the facial nerve and the auriculo-temporal nerves, no sialocele, simultaneous coronoidectomy via the same incision, and the ability to protect the internal maxillary artery by placing a retractor on the medial surface of the ramus and thus reducing the chance of haemorrhage.…”

Neurovascular structures of the mandibular angle and condyle: a comprehensive anatomical review

“…Although the condylar fracture is very frequent in mandibular fractures, the Frey syndrome occurs very rarely [19]. It has been recommended to approach the condylar area via a retroauricular or intraoral incision to prevent ATN or FN injury during the reduction of a condylar fracture or correction of TMJ ankylosis [4,32].…”

Comprehensive Management of Temporomandibular Joint Ankylosis — State of the Art

“…Recently, complete excision of the bony mass has been questioned regarding the increasing probability of the recurrence rate [10]. The underlying postulation was that leaving the opposing bony cut surface of the condyles after complete excision increase the amount of clot formation on dead space, which ultimately results in the formation of dense fibrous bridges that impede future mandibular movement [32]. Partial osteotomy of the region with minimal clot formation has been cited as a more potent surgical approach [32].…”
