Radiotherapy of Tympanojugular Ohemodectomas

The characteristic features and radiotherapy of chemodectomas of the tympanojugular region as seen in 16 cases are reported with respect to (a) survival, (b) regression of external ear manifestations, (c) vascular response, and (d) hormone response. Radiation treatment is effective in producing local tumor control; however, for a pheochromocytoma, irradiation should be combined with surgical removal of as much functional tumor as possible. Selective embolization may be effective in obliterating the tumor vessels following radiotherapy and thus arresting tumor progression.
