Whist 14 patients reported either a partial or complete relief of symptoms; complete data was available for 16 patients. The average time before the symptoms were relieved was slightly less than two months, with variations from three weeks to half a year. The researchers noted a relapse after the procedure in four patients, occurring between 3 and 18 months later.
None of the patients reported any major complications as a result of the procedure, with only two patients reporting any sensory side effects. The researchers conclude that radio surgery provides a viable alternative to more invasive approaches and should be further investigated.
