Background summary
30% of the patients who were treated by surgery and radiotherapy for a partod
tumor develop hearing loss. There is a dose-effect relation of radiotherapy and
hearing loss. using modern radiation techniques it might be expected that
hearing loss will decrease.
Study objective
1. To determine the incidence of clinical relevant hearing loss in patients who
inderwent postopertaive radiation for a parotid tumor.
2. To determine factors influencing hearing loss.
3. To determine the social impact of eventual hearing loss.
Study design
Using audiometry and a questionnaire hearing loss was measured. The mean dose
on middle ear, cochlea and Eustachian tube was estimated with a CT-planning
system.
Study burden and risks
Routine audiometry and a questionairre will be used.
