| Summary: | <p>Chemodectomas of head and neck region are rare, highly vascularized tumors which are categorized with respect to their site of origin and may be observed with periodical imaging or treated using either a single modality or multimodal approach including the primary management strategies of surgery and Radiation Therapy (RT). Temporal Bone Chemodectomas (TBC) include the tympanomastoid chemodectomas with modified Fisch Class A and B, and tympanojugular chemodectomas with modified Fisch Class C and D. An indolent disease course with low growth rate is typical for the majority of these mostly benign tumors, however, abrupt manifestation with severe symptomatology may also occur rarely in affected patients due to the mass effect with or without local invasion of critical neurovascular structures such as the internal carotid artery, jugular bulb, and lower cranial nerves. Affected patients may suffer from a plethora of symptoms such as otalgia, vertigo, pulsatile tinnitus, hearing impairment, headache, dysphagia, and dizziness. While surgery has been the traditional primary mode of treatment for these tumors, RT and more recently radiosurgery have been incorporated in management to achieve optimal therapeutic outcomes. Herein, we provide a concise review of RT for temporal bone chemodectomas. </p> |
