RESULTS: In terms of types of tumors, diabetes insipidus and waterª²sodium after surgery were found in 86 cases (78.9 %), with the highest in cases of craniopharyngioma (100%) and the lowest in cases of epidermoid tumor and meningiomas (60.0%-64.3%), and in terms of surgical approaches, the highest was found by ventriculus lateralisª²interventricular foramenª²the third ventricle (89.0%) and the lowest by hypoª²temporal lobe approach (79.0%). CONCLUSION: Surgical approaches and pathologic types have great influence on postª²operative diabetes insipidus and electrolyte disorder in sellar region. ......
