Surgical removal of large central neurocytomas with small incision approach

Abstract

Objective To investigate the strategy and technique of small incision surgery through interhemispheric transcallosal approach for removal of large central neurocytomas in supratentorial ventricule.  Methods Clinical data and therapy of 6 cases with central neurocytomas were retrospectively studied. All tumors were removed through small incision interhemispheric transcallosal approach, and the clinical data were analyzed.  Results Total resection was achieved in all cases. Three cases experienced transient mutism and one case experienced hemiparalysis. All of them received nerve-nurturing treatment and recovered within 2 weeks. Five cases were followed-up from 6 months to 2 years and there was no recurrence.  Conclusions The advantages of interhemispheric transcallosal approach include provision of sufficient surgical visual field and space, protection of normal brain tissue by natural cavity and shortest surgical pathway. Small incision surgery may not only reduce invalid brain exposure and hemorrhage during operation, but also decrease operation time. The small incision surgery through interhemispheric transcallosal approach is an effective choice for removal of central neurocytomas involved in supratentorial ventricule.
