Jankowski first reported endoscopic transsphenoidal resection of pituitary tumors in 1992, and with the development and introduction of endoscopic techniques, domestic scholars attempted simple endoscopic resection of pituitary tumors through a single nasal approach. Endoscopic single-nostril transsphenoidal approach for surgical resection has the following advantages: 1. Neuroendoscopy provides the operator with a closer, wider and better illuminated panoramic operative field observation, which breaks through the limitations of microsurgery and solves the problem of blind area of microscopic surgery. Under direct endoscopic view, the whole picture in the pterygoid sinus can be observed, and important signs such as internal carotid artery bulge and optic nerve bulge can be clearly identified, which reduces internal carotid artery bleeding, optic nerve This reduces the occurrence of serious complications such as internal carotid artery hemorrhage and optic nerve injury.
2.The flexible multi-viewing angle of endoscope and the function of “angle-wrap observation” can provide clear anatomy, so that the operator can observe the intra-saddle structure well, which makes it possible to remove the tumor minutely under the endoscope while preserving the pituitary function to the greatest extent, and avoiding the collateral damage as much as possible.
3.Neuroendoscopy 30°scope can resect the tumor tissue remaining in the deep part of the tumor cavity and the lateral wall, the pars and part of the suprasellar tumor. It reflects its superiority in the extent of tumor removal and avoiding side injuries.
4.The endoscopic single nostril approach, the neuroendoscopic surgical instruments reach the operation area directly from the same nostril next to the endoscope, without dilator to expand the nasal cavity, and enter the pterygoid sinus directly through the opening of the nostril, without damaging the nasal septum and its mucosa, without destroying the normal structure of the nasal cavity, effectively avoiding the destruction and reconstruction of the nasal mucosa and nasal septum structure, eliminating the possibility of complications in the nasal cavity and sinus.
