Abstract
Objectives
To present the clinical and radiographic findings in 8 patients with unusual primary tumors of the temporomandibular joint (TMJ).
Methods
This was a retrospective chart review of all patients with neurotologic manifestations caused by primary TMJ tumors seen at our tertiary care, academic medical center between 7/88-; 7/07.
Results
8 patients were identified with primary TMJ tumors that caused a variety of neurotologic manifestations, including trismus, otalgia, tinnitus, hearing loss, aural fullness, headache, facial pain, and otorrhea. Tumor histology included chondroma, chondroblastoma, osteoma, giant cell tumor, synovial chondromatosis, and osteosarcoma. Anterior external auditory canal involvement required partial petrosectomy in all 8 patients. Despite aggressive surgical resection and radiotherapy, only 5 of 8 patients are disease-free, with a mean follow-up of 7.2 years.
Conclusions
Primary tumors of the TMJ, although rare, can cause a variety of common neurotologic manifestations. A complete physical examination with appropriate radiographic assessment will guide the proper treatment plan. Earlier diagnosis may lead to improved overall control rates.
