An alternative approach for treating severe injured temporomandibular joints by gunshot wounds

摘要

Temporomandibular joint (TMJ) reconstruction is a challenging clinical problem that has been revolutionized due to the development of total alloplastic TMJ replacement (TMJ-TJR); however, the costs are still very high. We used an alternative approach to treat comminuted mandibular condyle fracture with an unviable condyle head caused by gunshot wounds. Our surgical technique consisted of an extended preauricular incision; removal of the fractured condyle, bone fragments, and foreign bodies; reshape/flattening of the fracture edge; fixation of the articular disc (if viable); lining of the TMJ with temporalis muscle/fascia; application of Erich arch bars; and early elastic therapy. We successfully used this approach in five sequential cases that resulted in a good mouth opening (35 mm) and satisfactory occlusion with teeth in maximum intercuspation. We believe that this technique is an excellent option for treating severe injured TMJs in places where TMJ-TJR is not available.
