OBJECTIVE: This study was designed to compare the efficacy of @entity455 ( @entity455 ) and Gamma knife radiosurgery (GKRS) for elderly idiopathic @entity4254 @entity1 by analyzing the clinical outcome. METHODS: In the past 10 years, 27 elderly @entity1 were treated with @entity455 while 18 @entity1 were treated with GKRS (>65-years-old). We reviewed their clinical characteristics and clinical courses after treatment as well as the treatment outcomes. For @entity1 who were treated with @entity455 , additional treatment methods such as rhizotomy were combined in some areas. In GKRS, we radiated the root entry zone (REZ) with the mean maximum dose of 77.8 (70-84.3) Gy and one 4 mm collimator. RESULTS: The mean age was 68.1 years for @entity455 , and 71.1 years for GKS group. The average time interval between first presenting symptom and surgery was 84.1 (1-361) months, and 51.4 (1-120) months, respectively. The mean follow-up period after the surgery was 35.9 months for @entity455 , and 33.1 months for GKRS. According to @entity158 Intensity Scale, @entity455 group showed better prognosis with 17 (63%) cases in grade I-II versus 10 (55.6%) cases in GKRS group after the treatment. The @entity158 recurrence rate during follow up did not show much difference with 3 (11.1%) in @entity455 , and 2 (11.1%) in GKRS. After the treatment, 2 cases of @entity1183 , and 1 case each of @entity4091 , cerebrospinal fluid (CSF) leakage, hearing disturbance, and subdural @entity1410 occurred in @entity455 Group. In GKRS, there was 1 (5.6%) case of @entity809 but was not permanent. Three cases were retreated by GKRS but the prognosis was not as good as when the surgery was used as primary treatment, with 1 case of grade I-II, and 1 case of recurrence. The maximal relieve of @entity158 was seen just after surgery in @entity455 group, and 1 year after treatment in GKRS group. CONCLUSION: For @entity4254 @entity1 with advanced age, @entity455 showed advantages in immediately relieving the @entity158 . However, in overall, GKRS was preferable, despite the delayed @entity158 relief, due to the lower rate of surgical complications that arise owing to the old age.
