  • Extended Transsphenoidal Microsurgical Approach for Diaphragma Sellae and Tuberculum Meningiomas
    Minimally invasive neurosurgery : MIN, 2009
    Co-Authors: Mario Francesco Fraioli, L. Moschettoni, R. Floris, E. Catena, B. Fraioli
    Abstract:

    Diaphragma Sellae meningiomas represent a difficult challenge for neurosurgeons; they are generally operated on by a transcranial approach. Some authors reported transsphenoidal surgery in selected cases, but without accurately focusing the surgical technique that should be necessary for removing the typical hard fibrous tissue of the meningioma, that is not aspirable, by this approach. We present the surgical technique and the useful instrumentarium for removing a Diaphragma Sellae meningioma through an extended microsurgical transsphenoidal approach.

  • Technical nuances in the management of tuberculum Sellae and Diaphragma Sellae meningiomas

    Co-Authors: Anil Nanda, Sudheer Ambekar, Vijayakumar Javalkar, Mayur Sharma
    Abstract:

    Object Tuberculum Sellae meningiomas (TSMs) and Diaphragma Sellae meningiomas (DSMs) are challenging lesions to treat due to their proximity to neurovascular structures. Methods The authors reviewed the medical records of patients who underwent surgical excision of TSMs and DSMs from 1990 to 2013. They also describe the technical strategies used to minimize injury to the optic apparatus, vascular structures, and pituitary stalk. Results Twenty-four patients with TSM and 6 patients with DSM were included in the study. Seventy percent of the tumors were large (≥ 5 cm). The pterional approach was employed in most cases. Optic canal involvement was observed in 4 patients. Twenty-one patients (70%) had visual dysfunction before surgery. At follow-up (median 18 months), visual improvement was noted in 10 (47.6%) of 21 patients. Gross-total excision was achieved in 22 patients (91.6%) with TSM and 5 (83.3%) with DSM. At last follow-up, 28 patients (93.3%) had a Glasgow Outcome Scale score of 5. There were no dea...

  • the use of a simple self retaining retractor in the endoscopic endonasal transsphenoidal approach to the pituitary macroadenomas technical note
    Neurosurgery, 2013
    Co-Authors: Murat Kutlay, Engin Gonul, Yusuf Izci, Ozkan Tehli, Caglar Temiz, Ilker Solmaz, Mehmet Daneyemez
    Abstract:

    BACKGROUND: During tumor removal in the endoscopic endonasal approach to pituitary adenomas with a significant suprasellar extension, the early descent of Diaphragma Sellae obscuring the visualization of the surgical field is a surgical challenge. OBJECTIVE: To describe a simple Diaphragma retraction technique to eliminate this problem. METHODS: A transparent flexible material (a strip of polypropylene) was used as a self-retaining retractor to elevate the redundant Diaphragma and to maintain the Diaphragma elevation. This technique was performed in 3 patients who had pituitary adenoma with suprasellar extension. The degree of tumor removal was determined by a combination of surgeon's intraoperative impression and the postoperative magnetic resonance imaging obtained 3 months later. RESULTS: The technique was performed very easily and no complication was observed owing to this technique and self-retaining retractor. Total tumor removal was achieved in 2 patients with this technique and subtotal removal in 1 patient. CONCLUSION: This technique was effective and practicable to elevate the Diaphragma Sellae during the tumor removal phase of transsphenoidal surgery. This simple self-retaining retractor may support the neurosurgeon's skill by providing control of the entire surgical field and adequate working space. It may also eliminate the risks of blind curettage during surgery.
