“…We assessed the functional and cosmetic outcomes, surgical complications and concluded that TPA could be successfully performed as an alternative method to traditional extended approaches and endoscopic routes in the skull base surgery. [38][39][40] In this report, we presented outcomes in 15 patients diagnosed with TSM. A surgical approach was selected with critical assessment of facial and bone anatomy, sizes of the tumor.…”

Background: The evolution of skull base approaches associated with individualization of surgical corridor and minimizing the collateral damage. Achieving the radical removal of tumor and preserving the neurological status of the patient is possible, both with the traditional approaches and keyhole approaches. Our work presents experience using the transpalpebral approach (TPA) for microsurgical removal of tuberculum sellae meningioma (TSM). Materials and Methods: A total of 15 patients with meningiomas underwent microsurgical removal of TSM through TPA. Ten patients were women and five were men. The standard preoperative diagnostic protocol includes magnetic resonance imaging with contrast enhancement, brain computed tomography for neuronavigation. We assess surgical complications, functional and cosmetic outcomes, and surgical parameters, including the time of surgery and intraoperative blood loss. Results: Visual impairment was finding in 100% patients, including slight decrease of vision (46,7%, seven patients), partial vision field loss (six patients, 40%), and serious visual impairment (two patients 13.3%). Visual improvement was noted in ten cases (66.7%), there was no improvement in four cases (26.7%), and one case (6.6%) had transient visual worsening for 4 days and slow improvement in 1 month. Headache disappeared in three patients (50%). There were no cases of cerebrospinal fluid leak. Transient frontal hypoesthesia was noted in all patients (100%) without permanent deficit. Transient palsy of the frontal muscle was noted in four patients for 4–6 months. Histological examination revealed WHO Grade I meningioma in 14 cases and in 1 case WHO Grade II meningioma. No deaths were identified in follow-up at 12 months. The average value of the Modified Rankin Scale was 1.4. The mean length of stay in hospital was 5. Conclusion: TPA is technically difficult and requires some experience to work in deep structures in a small surgical corridor. This technique can be good alternative to traditional fronto-lateral, supraorbital keyhole craniotomies, and endoscopic endonasal approaches.
