儿童后颅凹肿瘤较成人多见,约占儿童脑瘤的55～75%。其手术范围与远期疗效之间的关系尚未充分阐明。作者于1980～1981年曾对1964～1975年间手术的533例(?)～15岁的儿童小脑和第四脑室肿瘤患者进行了5～16年的长期随访和研究。其目的是探讨最有效的治疗方法及术后神经功能代偿的可能性。(一)小脑星形细胞瘤:共260例,其中150例获得随访。手术全切除占69%,部分切除31%。10年内死亡20例,死亡原因大多是肿瘤的生长和复发。在存活的130例患者中104例情况良好,不少病人正在学校学习或已参加工作并建立了美满家庭.35例神经系症状消失,69例遗有轻度小脑(?)脑干症
Posterior fossa tumors more common in children than adults, accounting for about 55 to 75% of children with brain tumors. The relationship between the surgical range and long-term efficacy has not been fully elucidated. The author conducted a long-term follow-up and study of 5-16 years for cerebellar and fourth ventricle tumors in 533 children (?) To 15 years of age who underwent surgery between 1964 and 1975 from 1980 to 1981. Its purpose is to explore the most effective treatment and postoperative neurological compensatory possibilities. (A) Cerebellar astrocytoma: a total of 260 cases, of which 150 were followed up. Surgical resection accounted for 69%, partial removal of 31%. Twenty cases died within 10 years, most of the causes of death are tumor growth and recurrence. Among the 130 surviving patients, 104 were in good condition and many were studying in school or had participated in the work and had a happy family.35 cases of neurological symptoms disappeared and 69 cases had mild cerebellar (?)
