Glomus tympanicum tumours are highly vascular tumours of the middle ear. Their removal by conventional surgical methods requires an extensive procedure in many cases, often with ossicular disarticulation to allow adequate exposure prior to the 'chaotic' and haemorrhagic event of tumour removal. This paper reports on the use of an NdYAG laser in a case of a large glomus tympanicum tumour. The laser facilitated a transcanal approach, avoided ossicular disarticulation and allowed accurate and
