摘要

The primary goals of surgery of tympanomastoid paragangliomas (TMPs) are tumor eradication and hearing preservation. Though the surgical management of TMPs has been dealt with widely in the literature, the effects of TMPs themselves on preoperative hearing and the audiological outcomes after surgery have not been analyzed in detail. This article comprehensively evaluates the preoperative hearing and the long-term hearing outcomes after surgery of TMPs. This study is based on a study population of 145 patients which is the largest reported in the literature. The surgical approaches for all patients with TMPs were formulated according to an algorithm developed by the authors. Complete tumor removal with excellent hearing results can be achieved by approaching the tumor classes by the right surgical technique. TMPs could possibly induce sensorineural hearing loss in higher frequencies, and future studies could be directed towards this.© 2014 S. Karger AG, Basel.
