Acute Temporomandibular Joint Dislocation during General Anesthesia Using LMA Supreme

Madhu Gupta, Renu Bansal, Kritika Rathore

Temporomandibular joint (TMJ) dislocation has been described in literature as a rare complication of LMA use. In this report, we describe the case of acute TMJ dislocation that occurred after LMA Supreme use in a 29 year old lady who underwent diagnostic hysterolaparoscopy under general anesthesia. The patient had an unremarkable airway and no history of TMJ subluxation or dislocation in the past. After induction of anesthesia, a size 3 LMA Supreme was successfully inserted in a single attempt after giving jaw thrust. After an uneventful surgical procedure the patient was reversed and the LMA Supreme was removed. After LMA removal, the patient was unable to close her mouth. The bony swelling palpable in the region anterior to bilateral TMJ confirmed the diagnosis of TMJ dislocation. A dental surgeon performed manual reduction of the same and the reduced position was secured using a bandage.
