[Tympanic and jugular paragangliomas. II. Angiographic, surgical and irradiation treatment. Results. Indications. Apropos of 25 cases].

Results of treatment are reviewed in 25 cases of tympanic and jugular paragangliomas treated and followed up in the Lariboisière hospital, Paris between 1978 and 1986. Therapy has been transformed by the use of embolization but its non-negligible neurologic accident risks, whatever the carotid artery territory involved, justify prior weighing of indications for its application. New surgical technics allow more extensive exeresis, but intrapetrous extension to the nerve compartment of the jugular foramen and the anterior pericarotid region still raises difficult surgical problems and appears to be the principal reason for failure of treatment. Radiotherapy is very effective and applicable for inoperable forms, as a complement to incomplete surgical removal and for recurrences.
