Chemodectoma of the temporal bone: a comparison of surgical and radiotherapeutic results.
Between January 1950 and December 1981, 32 patients with chemodectomas of the temporal bone were treated at the University of Iowa Hospitals and Clinics. Thirteen patients were treated with surgery alone, 15 with radiation therapy alone, one with preoperative radiation therapy and surgery, and three with surgery and postoperative radiation therapy. In general, the patients treated with radiotherapy alone or combined therapy (radiotherapy group) had more advanced tumors than those treated with surgery alone (surgery group). For the surgery group, the initial local control rate was 46% and the ultimate local control rate 84% following salvage with additional surgery, 31% developed complications, and 78% survived 10 years. For the radiotherapy group, 84% had local tumor control, 11% developed complications, and 77% survived 10 years. These results demonstrate that radiation therapy is an effective treatment modality for chemodectomas of the temporal bone.
