Summary
This case study details the successful surgical removal of a rare temporomandibular joint (TMJ) chondrosarcoma in a 67-year-old male. The procedure preserved critical facial nerve function, demonstrating surgical feasibility.
Area of Science:
- Head and Neck Surgery
- Oncology
- Neurosurgery
Background:
- Chondrosarcoma of the head and neck is uncommon.
- Chondrosarcoma of the Temporomandibular Joint (TMJ) is exceedingly rare.
- Presents a case of a large right TMJ chondrosarcoma in a 67-year-old male.
Observation:
- The patient underwent a complex surgical procedure.
- This included right segmental mandibulectomy with TMJ tumor excision.
- Additional procedures involved lateral temporal bone resection and infratemporal fossa resection with Vastus Lateralis flap reconstruction.
Findings:
- Complete resection of the TMJ chondrosarcoma was technically feasible.
- The surgical approach preserved the function of critical structures.
- Specifically, the ophthalmic branch of the facial nerve was successfully protected.
Implications:
- This case highlights a viable surgical strategy for rare TMJ chondrosarcomas.
- Demonstrates the possibility of achieving oncological clearance while maintaining neurological function.
- Offers valuable insights for surgeons managing similar complex head and neck tumors.
