Dislocation of the temporomandibular joint following general anesthesia

The Treatment of Temporomandibular Joint Dislocation

“…Iatrogenic triggers, such as anti-dopaminergic medication, intubation, endoscopic examinations, and prolonged dental treatments (e.g. tooth extractions) are less common (1,8,14). Here, dislocation is caused by prolonged and forced jaw opening in a patient with decreased muscle tone under medication (15).…”

“…Here, dislocation is caused by prolonged and forced jaw opening in a patient with decreased muscle tone under medication (15). Therefore, patients should be asked prior to any surgical procedure to be performed under general anesthesia about any previous dislocations and risk factors for dislocation (grade of recommendation [GoR] B; levels of evidence [LoE] IV-V +) (14,16). In addition, functional jaw mobility should be clinically checked before and after intubation to rule out temporomandibular joint dislocation (GoR B; LoE IV-V +) (14,16).…”

“…On clinical examination, an empty temporomandibular joint socket may be found and, in patients with long-term dislocation, signs of malnutrition (8). In patients under sedation, patients after trauma, patients with dementia and in patients with persistent dislocation, symptoms may be less noticeable so that the temporomandibular joint dislocation may initially be missed (1,8,14,16).…”

Bilateral Dislocation of Mandibular Condyles following General Anesthesia—An Overlooked Problem: A Case Report

“…4 Similarly, mandibular condyle tends to get dislocated by excessive maneuvering during tracheal intubation under general anesthesia. 5 6 7 It can occur at any time during laryngoscopy while intubation or extubation. 6 Here, we report a case of dislocation of TMJ following tracheal intubation in a 60-year-old woman that was overlooked for a prolonged period necessitating the resection of the condyle.…”

A Rare Instance of Temporomandibular Joint Dislocation Complicated by Motor-Evoked Potential Monitoring

“…These complications may require surgical treatment. 5 To the best of our knowledge, TMJ dislocation during MEP recording has not been reported in the literature till date. We hypothesize that in our case, MEP recording would have stimulated the facial motor cortex, contributing to the activation of facial muscles leading to TMJ dislocation.…”
