Abstract OBJECTIVE Tuberculum sellae meningiomas represent 5 to 10% of all intracranial meningiomas. Such lesions are classically removed through a variety of well-standardized transcranial approaches. The extended endonasal transsphenoidal route, under either microscopic or endoscopic visualization, has only recently been proposed as a viable surgical technique for the management of such tumors. MATERIAL AND METHODS A total of 51 consecutive patients with tuberculum sellae meningiomas were treated at our institution during a 21-year period. Forty-four patients had transcranial surgery, and the last seven were treated via the extended endoscopic transsphenoidal approach. We also compared our data with those reported in the pertinent literature related to the surgical, ophthalmological, and endocrinological outcome. RESULTS The significant difference among the transcranial and transsphenoidal series, both in our experience and in the reviewed literature, did not allow us to draw statistically significant results but rather a reporting of the outcomes. In the transcranial group, 86.4% had a gross total removal of the lesion, whereas the percentage was 83.3% in the transsphenoidal group. Concerning the visual outcome, we experienced postoperative improvement in 61.4% of the transcranial patients and a worsening of 13.6%, whereas improvement was reported in 71.4% of the patients in the transsphenoidal group; in the last group, we did not observe any postoperative worsening. The main drawback of the transsphenoidal approach still remains the difficulty in reconstructing the cranial base dural and bone defects, which expose patients to a greater risk of postoperative cerebrospinal fluid leakage (28.6% in our series) and related complications. CONCLUSION When treating a patient with a diagnosis of tuberculum sellae meningioma, a neurosurgeon should know that, aside from the classical transcranial approach, the possibility of an extended transsphenoidal approach exists. Although it is still not a standardized procedure, in carefully selected cases (i.e., small midline lesions, without major vessel encasement, or parasellar extension) and in experienced hands, it could be considered a viable alternative, especially in overcoming the reconstruction-related problems.

✓ The authors have developed an extended transsphenoidal approach with submucosal posterior ethmoidectomy for resection of tumors located in the cavernous sinus or the suprasellar region that are difficult to remove via the conventional transsphenoidal approach. Surgery was performed using this approach in 14 patients with large pituitary adenomas, three patients with craniopharyngiomas, and one patient with a meningioma of the tuberculum sellae. The submucosal dissection of the nasal septum used in the conventional transsphenoidal approach was extended to the superior lateral wall of the nasal cavity to expose the bony surface of the superior turbinate lying under the nasal mucosa. Submucosal posterior ethmoidectomy widened the area visualized through the conventional transsphenoidal approach both superiorly and laterally. This provided a safer and less invasive access to lesions in the cavernous sinus or the suprasellar region through the sphenoid sinus. Using this approach the authors encountered no postoperative complications, such as olfactory disturbance, cranial nerve palsy, or arterial injury. In this article the authors present the surgical methods used in this approach.

Abstract Background Tuberculum sellae meningiomas (TSMs) adherent to neurovascular structures are particularly challenging lesions requiring delicate and precise microneurosurgery. There is an ongoing debate about the optimal surgical approach. Method We describe technical nuances and challenges in TSM resection using the endoscopic endonasal approach (EEA) in two cases of fibrous tumors with adherence to neurovascular structures. The cases are illustrated with a video (case 1) and figures (cases 1 and 2). Conclusion A dedicated team approach and precise microsurgical technique facilitate safe resection of complex TSMs through the EEA.

Tuberculum Sellae

✓ This 70-year-old woman suffered a subarachnoid hemorrhage (SAH) from a ruptured anterior communicating artery aneurysm encased in a meningioma in the tuberculum sellae. Although preoperative magnetic resonance imaging disclosed that the aneurysmal complex was completely enclosed in the tumor, angiographic studies did not reveal arterial narrowing. The embedded aneurysm caused diffuse SAH rather than intratumoral hemorrhage. These factors indicated very little adhesion between the tumor and the encased arteries. Surgery was performed on the 20th day post-SAH. Intraoperative findings revealed that the tumor did not adhere to the enclosed vasculature except at the point of rupture of the aneurysm. The authors were able to clip the aneurysm safely after piecemeal removal of the tumor, which was finally extirpated without fear of aneurysm rupture. Careful stepwise procedures were essential to treat the aneurysm and the tumor simultaneously.

Object. The extended transsphenoidal approach, which requires a bone and dural opening through the tuberculum sellae and posterior planum sphenoidale, is increasingly used for the treatment of nonadenomatous suprasellar tumors. The authors present their experiences in using the direct endonasal approach in patients with nonadenomatous suprasellar tumors. Methods. Surgery was performed with the aid of an operating microscope and angled endoscopes were used to assess the completeness of resection. Bone and dural defects were repaired using abdominal fat, collagen sponge, titanium mesh, and, in most cases, lumbar drainage of cerebrospinal fluid (CSF). Twenty-six procedures for tumor removal were performed in 24 patients (ages 9–79 years), including two repeated operations for residual tumor. Gross-total removal could be accomplished in only 46% of patients, with near-gross-total removal or better in 74% of 23 patients (five of eight with craniopharyngiomas, six of seven with meningiomas, five of six with Rathke cleft cysts, and one of two with a dermoid or epidermoid cyst); a patient with a lymphoma only underwent biopsy. Of 13 patients with tumor-related visual loss, 85% improved postoperatively. The complications that occurred included five patients (21%) with postoperative CSF leaks, one patient (4%) with bacterial meningitis; five patients (21%) with new endocrinopathy; and two patients (8%) who needed to undergo repeated operations to downsize suprasellar fat grafts. The only permanent neurological deficit was anosmia in one patient; there were no intracranial vascular injuries. Conclusions. The direct endonasal skull-base approach provides an effective minimally invasive means for resecting or debulking nonadenomatous suprasellar tumors that have traditionally been approached through a sublabial or transcranial route. Procedures in the supraglandular space can be performed effectively with excellent visualization of the optic apparatus while preserving pituitary function in most cases. The major challenge remains developing consistently effective techniques to prevent postoperative CSF leaks.
