Clinic analysis of microsurgery via pterion approach for tumor in sellar region

Objective:To summarize the clinical experience of the microsurgical operation for sellar region tumors via the pterional approach.Methods:The clinical data of 42 patients with sellar region tumors were retrospectively analyzed.All patients were treated by microsurgery via modified transpterional in our hospital inrecent 3 years.The operative resutlts and complications of microsurgery were discussed,and the factors affecting the choice of the pterional approach were analyzed.Results:Of 42 cases,31 had total resection,and 11 cases had subtotal resection,with total resection rate as 73.8%.1 patients had facial paralysis.18 patients had diabetes insipidus and electrolyte disorder.There was no death.Conclusion:The pterional approach for removing sellar region tumors can offer clear operation visual fields,and sufficient exposure of the tumor and it's surrounding structures.It can improve the patients'life quality and decrease the recurrence of the tumor.
