Abstract

Abstract:

Pigmented villonodular synovitis (PVNS) is a rare locally aggressive benign tumor in the temporomandibular joint (TMJ). This paper presents a patient with TMJ-PVNS involving masseteric space, temporal bone, zygomatic process, and mandibular ramus. Digital technique was used to determine the boundary of the lesion and reconstruct the normal glenoid fossa. The temporalis myofascial flap was transplanted between titanium mesh and condyle to reconstruct the disk after the complete resection of the tumor. The patient’s facial profile is symmetrical, with a mouth ope-ning of 43 mm. No local recurrence and complications, such as cerebrospinal fluid fistula and encephaloceles, were detected during 30-month follow-up period.

Key words: temporomandibular joint, pigmented villonodular synovitis, digital reconstruction, temporalis myofascial flap
