ObjectiveTo investigate the application effect of electromagnetic navigation guiding neuroendoscopy in the approach of transsphenoidal via single nostril in the performance of pituitary tumor resection. MethodsA total of 32 patients undergoing electromagnetic navigation-guided neuroendoscopy in the approach of transsphenoidal via single nostril to perform pituitary tumor resection were selected, and they were given preoperative MRI thin-layer scanning. Three-dimensional reconstruction was performed by in-typing image data into the StealthStation S7 neural navigation system, based on which tumors and important structures were marked. Structures such as the anterior wall of sphenoid sinus, internal carotid artery, sellar floor, cavernous sinus, and clivus were identified via endoscopy guided by the electromagnetic navigation system, and the tumors were removed. The postoperative effects of the patients were observed. ResultsAll the 32 patients had completed the surgery successfully, with electromagnetic navigation-guided endoscopy in the approach of transsphenoidal via the single nostril, of which 25 patients underwent total tumor resection, 4 patients with subtotal resection, and 3 patients with partial resection. The symptoms of the 32 patients were improved to varying degrees after operation, without the occurrence of serious complications. ConclusionElectromagnetic navigation-guided neuroendoscopy via transsphenoidal single nostril approach in performing pituitary tumor resection can improve the accuracy of surgical operation, with fewer complications, and it is safe and effective.
