Mendenhall, MD complications of radiation therapy to the temporal bone, Abstract: The purpose of this study was to establish guidelines that multiple groups advocate the use of complex radiation deliv- help radiation oncologists contour the inner and middle ear on ery systems such as intensity modulated radiation therapy treatment planning scans. The radiotherapy computed tomography (IMRT) or proton beam therapy that are able to generate dose (CT) scans of 15 previously treated patients were reviewed for the distributions with a steep dose gradient across the auditory ability to identify 3 separate auditory structures. The middle ear, the 1,4,10 cochlea, and the vestibular apparatus were identified and contoured apparatus. Application of such complex radiation deliv- on each scan using anatomic landmarks. The volume and maximum ery systems requires that the contouring of structures be as axial dimension of each contour were calculated. The middle ear, accurate as possible. The small size of the inner ear and close cochlea, and vestibular apparatus were identified on all scans. The proximity to the
