Closed Lock of the Jaw on Induction of Anesthesia / 대한마취과학회지

ABSTRACT

The temporomandibular joint (TMJ) is unique among joints in the human body, since it can be dislocated without external force. Manipulation of the upper airway other than laryngoscopy is a risk factor in patients who have a history of habitual dislocation of the TMJ. The case report illustrates that severe limitation of the jaw opening ("closed lock") requiring manipulation for restoration may occur during induction of general anesthesia.
