title: Juxta-articular Myxoma of the Temporomandibular Joint.
abstract: The juxta-articular myxoma represents a benign mesenchymal neoplasm that arises from tissue within or adjacent to a joint space. There have been a number of reported cases involving myxomas of the knee, shoulder, elbow, wrist, and hip. To our knowledge there, however, have been no reported cases of juxta-articular myxomas of the temporomandibular joint (TMJ). This report describes the case of a 57-year-old woman with a juxta-articular myxoma of the left TMJ extending into the infratemporal fossa (ITF). Access to the tumor was accomplished via a preauricular incision and low condylar osteotomy which allowed for displacement of the condyle for direct visualization and excision of the tumor. The postoperative course was benign and the patient demonstrated no cosmetic or functional limitation. Likewise, follow-up at 30 months showed no evidence of recurrence. Benign encapsulated tumors of the ITF can be effectively accessed by means of a modified preauricular incision, low condylar osteotomy, and anterior meniscal release. This direct approach allows for excellent surgical exposure, minimal surgical site morbidity, and maintenance of physiologic joint function and occlusion.
