Frameless Stereotactic Placement of Brachytherapy Seeds within a Pituitary Adenoma via Endoscopic, Endonasal Approach: A Technical Note

AbstractForamen magnum (FM) tumors represent one of the most complex cases for the neurosurgeon, due to their location in a very anatomically complex region surrounded by the brainstem and the lower cranial nerves, by bony elements of the craniocervical junction, and by the vertebrobasilar vessels. Currently, the open approach of choice is a lateral extension of the posterior midline approach including far lateral, and extreme lateral routes. However, the transoraltranspharyngeal approach remains the treatment of choice in cases of diseases affecting the craniocervical junction. For very selective cases, the endoscopic endonasal route to this region is another option. We present a case of a ventral FM meningioma treated exclusively with the endoscopic endonasal approach.

Background: Transphenoidal endoscopic approach is minimal invasive surgery in case of pituitary adenoma. Objective : To see the outcome of transphenoidal endoscopic and microscopic approach in case of pituitary tumor. Results : This study showed among the 37 patients, 25 (67.6%) were done by transphenoidal microscopic approach and 12 (32.4%) patients were done by endonasal endoscopic approach. Among the 12 patients 8(66.7%) were male and 4(33.3%) were female. Among the 25, patients 15(60%) were male and 10(40%) were female. It was documented that in 12 patients, 10(83.3%) were macroadenoma and 2(16.7%) were microadenoma. It was evident that among the 25 patient 18(72%) were macroadenoma and 7(28%) were microadenoma. Among 12 patients, 11 (91.7%) had preoperative visual disturbance and 1(8.3%) had normal vision. It was observed that among 25 patients, 23(92%) patients had preoperative visual disturbance and 2 (8%) patients had normal vision. Tumor was totally removed in 9(75%) patients in endoscopic approach and 14(56%) in microscopic approach. Clinically 10(83.3%) patients were improved in endoscopically and 16(64%) patients were improved in microscopic group. Conclusion: It was concluded that endoscopic endonasal approach is better than transphenoidal microscopic approach. Bangladesh Journal of Neuroscience 2015; Vol. 31 (1): 21-29

Objectives The current video presents the nuances of the infrasellar endoscopic endonasal approach for a pituitary adenoma extending into the third ventricle, with anterior displacement of the pituitary gland. Design The video analyzes the presentation, preoperative workup and imaging, surgical steps and technical nuances of the surgery, the clinical outcome, and follow-up imaging. Setting The patient was treated by a skull base team consisting of a neurosurgeon and an ENT surgeon at a teaching academic institution. Participants The case refers to 73-year-old female patient who was found to have a sellar mass after failure of vision to improve with cataract surgery. She also reported a several-month history of progressive loss of vision along with daily retro-orbital headaches. The adenoma extended into the clivus as well as in the retrosellar and suprasellar regions, eroding into the floor of the third ventricle. The normal gland was displaced anteriorly. Main Outcome Measures The main outcome measures consisted of reversal of patient symptoms (headaches and visual disturbance), recurrence-free survival based on imaging, as well as absence of any complications. Results The patient's headaches and visual fields improved. There was no evidence of recurrence. Conclusion The infrasellar endoscopic endonasal approach is safe and effective for pituitary adenomas extending into the third ventricle, with anterior displacement of the pituitary gland.The link to the video can be found at: https://youtu.be/zp_06mEyRvY.
