Resection of synovial chondrosarcoma of temporomandibular joint involving the skull base with simultaneous reconstruction: report of one case

Abstract

Abstract: Synovial chondrosarcoma (SCS) is a rare malignant cartilaginous tumor that arises from synovial chondromatosis (SCM) or de novo. To our knowledge, only three previously studies reported its involvement of temporomandibular joint (TMJ). Here, we present a case of a 56-year old woman with a SCS of TMJ involving the infratemporal space and the skull base. The lesion was resected with the aid of the digital template, while the skull base and the condyle were immediately reconstructed with ilium bone flap (IBF) and pedicled sternoclavicular joint (SCJ). There was no clinical or imaging sign of local recurrence and bone metastasis during 1-year follow-up period, but metastasis to lung was observed.

Key words: Temporomandibular joint, Synovial chondrosarcoma, Digital template, Ilium bone flap, Sternoclavicular joint
