KTP laser assisted excision of glomus tympanicum

Abstract

AbstractA 39-year-old female with a two-year history of mild hearing loss and discomfort on air flight descent was found to have a pulsatile mass behind an intact tympanic membrane. A suspected diagnosis of glomus tympanicum was confirmed by computed tomography (CT) scan imaging. The lesion filled the mesotympanum and hypotympanum but the jugular bony plate was intact, confirming the tympanic site of the lesion. This very vascular tumour was exposed by a tympanomeatal flap and the KTP laser used to shrink and coagulate the tumour progressively with minimal haemorrhage and blood loss. Complete excision of the lesion was achieved without the need for bony removal, and with minimal blood loss. The use of the KTP laser to coagulate this vascular lesion allowed safe removal of the tumour and avoided the need for extended facial recess or hypotympanotomy surgery.
