During the years 1984 to 1991, of 32 patients who had one large glomus or carotid body tumour, six were found to have other paragangliomas. Excluded from the above total of 32 are patients whose only lesion was a solitary glomus tympanicum. No two patients had identical problems and no pattern emerged on which patient management in any particular case could be based. The major problems associated with the tumours themselves and their treatment is the risk to hearing and the lower cranial nerves. Individual cases and their treatment are discussed.
