ABSTRACT
Objective To study clinical effects and complications of minimal invasive neurosurgery for pituitary adenoma through superciliaryarch-keyhole approach. Methods 127 cases pituitary adenoma in three hospitals in Shangdong province from May. 2006 to Sept. 2009 confirmed by surgery were analyzed. Patients were treated by different operative approaches, 53 cases using surgery through superciliaryarch-keyhole approach and 74 cases through conventional subfrontal approach. Clinical parameters were compared in patients undergoing surgery through different approaches. Results There were no differences in two groups, in aspects such as resection rate, improvment of endocrine hormone secretion and acuity of vision with campus visualis, electrolyte disturbances, hypothalamus damage (P ＞0.05). Significant differeces reside in average hospitalization days, subcutaneous fluidify, psychiatric symptom and circumscribed cerebral ischemia ( P ＜ 0.05 ). Conclusion Advantages of minimal invasive neurosurgery through superciliary arch approach such as less trauma, better expose,shorter hospitalization days, less subcutaneous fluid accumulation and psychiatric symptoms in terms of this apporach are suitable for removing hypophyseal adenomas that grow on or around sella turcica.
