    Introduction: We describe our expendient surgical strategy for craniopharyngiomas and hybrid surgery using microscope and neuroendoscope for total tumor removal.

    Methods: Ninety one patients with cranipahrynigoma were treated our Hospital (38 patients operated by only microscope from 1974 to 2000, 53 patients operated by hybrid surgery using microscope and endoscope from 2011 to 2012). We analyzed recurrence rate and GOS of only microscopic surgery (1974-2000) vs. hybrid surgery.

    Results: Samii’s grade of 91 patients was as follows; Grade I-1, II-16, III-37, IV-31, V-6. Expedient surgical approaches were 40 pterional/subfrontal, 30 interhemispheric, 16 transshenoidal apprpaches, so on. Eight (21%) in 38 patients were recognized tumor recurrence from 1974 to 2000 by only microscopic surgery. On the other hand, 5 (9.4%) in 53 patients recognized tumor recurrence from 2001 to 2012 operated by hybrid surgery using microscope and neuroendoscope. Advantage of hybrid surgery is as follows; wide and clear view, fit to deep-seated tumors, ordinary instruments can use, microscopic surgical education to junior Neurosurgeon can do, and residual tumor of dead space for example under optic chiasm by hybrid surgery. On the other hand, disadvantage of this surgery is as follows; 2D, special practice is needed, narrow space, adhesion, ossified tumor, or vascular tumor.

    Conclusions: We introduce expedient approaches and our hybrid surgery using microscope and neuroendoscope for craniopharyngioma surgery. This procedure is useful to do conventional microneurosurgery for surgical education, moreover, it can remove residual tumor by hybrid surgery.

    Patient Care: Our clinical research of hybrid surgery may relate to improve of rerecurrence rate.

    Learning Objectives: Hybrid surgery using microscope and endoscope (hybrid surgery) of craniopharyngiomas
