Jaw Dislocation as an Unusual Complication of Upper Endoscopy

Area of Science:

• Gastroenterology
• Oral and Maxillofacial Surgery

Background:

• Temporomandibular joint (TMJ) dislocation is a known complication associated with anesthesia and endotracheal intubation.
• Its occurrence as a direct complication of gastrointestinal endoscopy is infrequently reported and recognized.

Observation:

• A case report detailing an unusual complication of upper endoscopy leading to temporomandibular joint dislocation.
• The patient experienced jaw pain and limited mobility following the endoscopic procedure.

Findings:

• Jaw dislocation is an underreported risk of upper endoscopy.
• Potential causes include patient positioning, instrument manipulation, and pre-existing TMJ conditions.
• Differential diagnoses for post-endoscopy jaw pain include muscle strain and referred pain.

Implications:

• Clinicians should be aware of the potential for TMJ dislocation during upper endoscopy.
• Recommendations for prevention include careful patient selection, modified procedural techniques, and prompt recognition and management of suspected dislocations.
• Further research is warranted to elucidate the precise mechanisms and incidence of this complication.
