Tympanoplasty using a postauricular peropsteal-pericranial flap for tympanic membrane perforation after chemoradiotherapy for nasopharyngeal carcinoma : A case report

Abstract

After chemoradiotherapy (CRT) for nasopharyngeal carcinoma, natural closure of tympanic membrane perforations becomes difficult due to Eustachian tube dysfunction, middle ear mucosal fibrosis, and local vascular impairment. We report a case of tympanoplasty using a postauricular periosteal-pericranial flap for tympanic membrane perforation following CRT, achieving favorable healing. The use of a well-vascularized flap suggests the possibility of successful tympanic membrane closure even in the poor healing environment after radiotherapy.
