Abstract
Aim
To report our experience with the outcomes of open microsurgical management of third ventricular colloid cysts.
Material and Methods
This retrospective study presents the surgical outcomes of 33 patients who underwent open microsurgical resectioneither through the interhemispheric transcallosal or transcortical transventricular approachfor third ventricular colloid cysts between 2010 and 2023.
Results
The mean follow-up period was 41.57 months. All patients were symptomatic, and severe, intractable headache was the most common presenting symptom. No perioperative mortality or postoperative infection occurred. During follow-up, five patients (15.15%) developed shunt-dependent hydrocephalus, and eight (24.24%) developed seizures. At the last follow-up, seven of the eight patients were seizure-free and no longer required antiepileptic medication. Thirty-two patients (96.96%) had no recurrence, and in one patient with a small residual lesion, no progression was observed.
Conclusion
Open microsurgery, whether via the interhemispheric transcallosal or transcortical transventricular approach, is safe and offers a high likelihood of total resection with low recurrence. Shunt-dependent hydrocephalus and postoperative seizures remain the most common complications, underscoring the need for long-term surveillance, particularly for late-onset seizures even after complete removal. Although endoscopic surgery is now widely adopted, our findings demonstrate that open microsurgery continues to be a reliable and durable option with favorable recurrence and complication profiles.
