Case report of chondromyxofibroma involving the overall structure of the temporomandibular joint: surgical resection and reconstruction

doi:10.19438/j.cjoms.2024.04.016

Abstract

Abstract: Chondromyxoid fibroma (CMF) is an exceedingly rare benign bone tumor, to the authors' knowledge, only one case primarily occurred in temporomandibular joint(TMJ) has been reported in the literature. This paper presented a patient with TMJ-CMF involving pterygopalatine space, and the skull base thereof. 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 so as to reconstruct the disk after complete resection of the tumor. The patient's facial profile is symmetrical, with a mouth opening of 45 mm. There was no local recurrence, no complications such as cerebrospinal fluid fistula and cerebral hernia during 1-year follow-up period.

Key words: Temporomandibular joint, Chondromyxoid fibroma, Digital reconstruction, Temporalis myofascial flap
