Chemodectomas of the head and neck.

The authors' experience in dealing with 10 cases of chemodectomas occurring in head and neck is outlined. The symptomatology of these tumors is discussed with their investigation and management. Analysis of this series suggests that polytomography is the most valuable tool in diagnosing lesions within the confines of the temporal bone, whereas angiography is the most rewarding method of investigating cervical lesions. Surgical resection is the preferred method of treatment, and the most definitive. However, in those cases where the patient's general medical condition or the size and location of the tumor create unacceptable risk factors, radiotherapy may be employed as a palliative measure.
