Introduction of a Novel Technique for Reduction of Temporomandibular Joint Dislocation

Background and Objective: Although the conventional method for reduction of acute mandibular dislocation has been a versatile one, it occasionally fails to relocate the condyle within the glenoid fossa. Application of heavy forces is inevitable in some clinical scenarios which potentially can cause damage to condylar structures. Moreover, the heavy force used in conventional method may be difficult for the patient to tolerate and also it can necessitate the use of adjunctive methods such as medications. The aim of this technical note is to present a novel method for reduction of acute anterior dislocation of mandibular condyle. Materials and Methods (TECHNIQUE): In anterior dislocation of TMJ, the coronoid process moves forward and downward; thus it would be readily palpable lateral to the upper molar teeth. The clinician should touch the soft tissue covering the superior and lateral aspects of the coronoid process by his/her index finger. All one should do then is to slightly rotate the jaw and put mild pressure against the process allowing the condyle to relocate into glenoid fossa. The maneuver should be accomplished on one side first. After reduction of one condyle, the opposite condyle will be easily reduced. Conclusion: This maneuver has been applied by the author in 130 cases and it has been successful in all cases of anterior condylar dislocation. It is very effective and simple, comfortable for the patients, does not need any equipment or medications, and eliminates the risk of damage to jaw structures.
