    Abstract:
    The main purpose of surgery for tuberculum sellae meningioma (TSM) is the improvement and/or stabilization of patients' visual function. Options for the side of lateral approaches usually were restricted for nondominant right-sided craniotomy or to the side of impaired vision (ipsilateral approaches). Although the safety and effectiveness of ipsilateral transcranial approach was proved, there are some doubts and discussions about the contralateral craniotomy. We retrospectively analyzed the series of contralateral surgeries of TMS and their visual outcomes comparing with ipsilateral approach. Twenty-six patients with TSM were operated on from 2010 to 2019 (F/M 20/6, mean age 49 years), in 17 (65%) we performed contralateral and in 9 (35%) ipsilateral approach. All procedures were performed via fronto-lateral craniotomy. Gross total resection (GTR) was achieved in 21 (81%) cases and in all but one patient we noticed visual improvement after surgery (96%). Optic canal unroofing with mobilization of more affected visual nerve was necessary in 5/9 pts of ipsilateral vs 3/17 pts of contralateral group. We had no significant postoperative complications.There was no difference in outcome between ipsilateral and contralateral fronto-lateral approaches for TSM resection; thus, contralateral approach was at least as safe and effective as ipsilateral.
