Temporomandibular Joint Ankylosis

Abstract

AbstractThe purpose of this chapter is to inculcate a newer, deeper understanding of TMJ Ankylosis– both from the pathological as well as the clinical view point. Newer classifications may now determine surgical procedures. Interpositional materials may not be just soft tissues interposed between the cut ends, but also hard tissues forming the new Ramus Condyle Unit (RCU). Facial deformity may be recognized to be as important as inability to open the mouth; more so, if accompanied by Obstructive sleep apnea (OSA). Multi-staged treatment plans of release first followed by asymmetry correction may be replaced by single staged joint replacement & total facial aesthetic as well as functional rehabilitation. Finally, the importance of unfavorable events in TMJ Ankylosis surgery may be recognized, which would lead to better results in terms of treatment goals, i.e. to restore joint function, improve facial appearance & airway issues, correct malocclusion & re-establish harmony between the TMJ, the face and the teeth.
