Anaesthetic Management Of Bilateral TMJ Replacement In Case Of Ankylosis Of TMJ And Micrognathia

Abstract

Temporomandibular joint (TMJ) ankylosis is defined as bony or fibrous adhesion of the anatomic joint components accompanied by limitation of mouth opening, causing difficulty in mastication, speech, and oral hygiene. This may also influence symmetry of the facial skeleton. This interferes with mastication, speech, oral hygiene, and normal life activities, sleep related breathing disorder characterized by repeated episodes of apnoea and hyperpnea during sleep and can be potentially life threatening when struggling to acquire an airway in an emergency. Severe OSA with repeated nocturnal hypoxia associated with pulmonary hypertension may result in right heart failure, biventricular dysfunction and congestive cardiac
failure, significantly increase the risk of haemodynamic instability in perioperative period
