Intrinsic Jaw Injuries

Treatment of Intrinsic Injuries to the Jaw’s Temporomandibular Joint. Sustained mouth opening and hyperextension injuries are the most common intrinsic injuries of the temporomandibular joint (TMJ). Hyperextension injuries of the temporomandibular joints can occur during intubation for general anesthesia, likely because the jaw muscles are paralyzed during induction, making the TMJ more susceptible to hyperextension.
