Abstract
Three patients with glomus tumor who presented complaining of pulsatile tinnitus were treated by surgery. They included one case each of glomus tympanicum, glomus jugulare, and glomus jugulotympanicum, in which the clinical distinction between the tympanicum extension of the glomus jugulare tumor and the jugular fossa extension of the glomus tympanicum tumor had been difficult. Although the first 2 cases underwent a successful total tumor removal, the latter case had to undergo a repeated partial tumor removal because the initial surgery had been completed before conducting accurate radiological examinations. Based on the above findings, both high resolution CT and MRI help to identify the most appropriate surgical treatment.
