Anterior Interhemispheric Transcallosal Approach for the Treatment of Colloid Cysts of the Third Ventricle: Results of a Single-Center Retrospective Study

Abstract

Objective: The cases operated using the microscopic anterior interhemispheric transcallosal approach due to third ventricular colloid cyst during 2015–2020 in our clinic were discussed in the light of the literature. Methods: Seven patients (four females, three males) operated for colloid cyst of the third ventricle were examined retrospectively in terms of their presentation complaints, neurological examinations, size of the colloid cysts detected, presence/absence of accompanying hydrocephalus, surgery performed, callosal incision diameter used in the surgery, post-operative neurological conditions, complications, epilepsy, and development of disconnection and neurocognitive disorders. Results: No neurological deficits were observed in the post-operative examinations of any patients. It was observed that the colloid cysts of six patients were completely removed. None of the patients required shunts during their follow-up, and epileptic seizure, disconnection syndrome, and neurocognitive disorders were not observed. Conclusion: The anterior interhemispheric transcallosal approach is a safe way to treat colloid cysts of the third ventricle for a good total resection, with a short operative time. This is associated with minimal morbidity.
