Background: The resection of planum sphenoidale and tuberculum sellae meningiomas is challenging. A universally accepted classification system predicting surgical risk and outcome is still lacking.
Objectives: We report a modern surgical technique specific for planum sphenoidale and tuberculum sellae meningiomas with associated outcome. A new classification system that can guide the surgical approach and may predict surgical risk is proposed.
Methods: We conducted a retrospective review of the patients who between 2005 and March 2015 underwent a craniotomy or endoscopic surgery for the resection of meningiomas involving the suprasellar region. Operative nuances of a modified frontotemporal craniotomy and orbital osteotomy technique for meningioma removal and reconstruction are described.
Results: Twenty-seven patients were found to have tumors arising mainly from the planum sphenoidale or the tuberculum sellae; 25 underwent frontotemporal craniotomy and tumor removal with orbital osteotomy and bilateral optic canal decompression, and 2 patients underwent endonasal transphenoidal resection. The most common presenting symptom was visual disturbance (77%). Vision improved in 90% of those who presented with visual decline, and there was no permanent visual deterioration. Cerebrospinal fluid leak occurred in one of the 25 cranial cases (4%) and in 1 of 2 transphenoidal cases (50%), and in both cases it resolved with treatment. There was no surgical mortality.
Conclusion: An orbitotomy and early decompression of the involved optic canal are important for achieving gross total resection, maximizing visual improvement, and avoiding recurrence. The visual outcomes were excellent. A new classification system that can allow the comparison of different series and approaches and indicate cases that are more suitable for an endoscopic transsphenoidal approach is presented.

Background: The co-occurrence of Rathke cleft cysts (RCCs) and meningiomas in the sellar and parasellar regions represents an exceedingly rare clinical entity. Achieving maximal resection through a single operative approach while minimizing adverse events is challenging, often necessitating multiple surgical approaches, as suggested by previous reports.
Observations: The authors report the case of a 49-year-old female with a history of kidney transplant who presented with headaches and was diagnosed with coexisting RCC and meningioma in the sellar and planum sphenoidale regions, respectively.

The endoscopic transsphenoidal approach is a common approach used in skull base neurosurgery to reach the sellar region. One of the intraoperative risks of this approach is intraoperative bleeding out of the carotid artery. Gentle drilling can prevent carotid artery injury.

Background And Purpose: Preoperative embolization of anterior skull base meningiomas can facilitate surgical resection by reducing tumor vascularity. However, transophthalmic artery embolization carries risks of visual complications. This study aimed to evaluate the safety and efficacy of this technique using modern endovascular tools.

Background: The preservation of olfaction during the surgical resection of anterior skull base meningiomas presents a significant challenge. This study presents a modified endonasal endoscopic L-shaped approach designed to maximize tumor resection while preserving olfaction, a vital function that profoundly impacts the quality of life.
Methods: A cadaveric dissection was conducted to refine the surgical technique, and this approach was subsequently applied to a 34-year-old female patient presenting with a large planum sphenoidale meningioma.

As skull base defects become increasingly complex, necessitating more extensive repairs, alternative strategies are needed to address challenging reconstructions and rescue cases of failed primary reconstruction. In this study, we aimed to validate the surgical technique and assess the feasibility of using the platysma myocutaneous flap for skull base reconstruction, using cadaveric specimens in a preclinical setting. This descriptive anatomical study was conducted on 2 fresh human cadavers (4 sides).
