Stereotactic multiple arc radiotherapy. II--Cranial neuroma.
We report our early experience using stereotactic radiotherapy (radiosurgery) in the treatment of cranial neuroma, by the linear accelerator method. We report the first 13 neuromas treated in 12 patients (follow-up 6-60 months). Radiologically, seven of 10 patients demonstrated signs of central tumour necrosis on follow-up scanning and four of these also demonstrated shrinkage. Of seven assessable acoustic neuroma patients treated, hearing was stabilized in three and improved in two. An abducent neuroma patient treated by this method is reported and demonstrated good response. Our preliminary studies endorse the opinion that stereotactic radiosurgery is a suitable and safe alternative to microsurgical procedures in the management of many cranial neuromas. Indications for stereotactic radiosurgery are discussed.
