In 1966, German scholars tried to make telescopic rigid straight nasal endoscope based on the theory of columnar mirror and combined with cold light source system, which has the advantages of wide field of view and strong light guiding ability. In the early 1970s, Austrian rhinologists created a new field of transnasal endoscopic sinus surgery, i.e., through various angles of the endoscope, the lesions in the hidden parts of the sinuses can be completely removed. This technique was introduced to China in the early 1980s and has now become a minimally invasive surgical technique widely used in otorhinolaryngology-head and neck surgery. The surgical operation is performed in the nostrils and there is no incision on the nasal face, which is a surgical technique that can get rid of the disease while preserving the normal physiological function, and can be said to be one of the most important advances in rhinology technology in the last century.
1.What are the advantages of nasal endoscopic surgery Nasal endoscopic surgery is also called functional endoscopic surgery. It can make the surgery more delicate through the good illumination of the nasal endoscope and the supporting surgical instruments; transform the traditional destructive surgery of radical or total scraping of the mucous membrane in the sinuses into a functional surgery that preserves the normal mucous membrane and structure of the nasal cavity and sinuses as much as possible, forms good ventilation and drainage, and promotes the recovery of the morphology and physiological function of the mucous membrane of the nasal cavity and sinuses on the basis of the complete removal of lesions; and Depending on the severity of the lesion, it can achieve the purpose of curing rhinitis, sinusitis and nasal polyps by relying on the recovery of the physiological functions of the nasal cavity and sinuses themselves. Due to its strong light guide, multi-angle and large field of view, it can directly peer into many important parts of the nasal cavity (such as each sinus opening, each sulcus, hidden narrow places inside the sinuses) and subtle lesions in the nasopharynx. In addition to surgical treatment, it can also be videotaped at the same time to preserve data for consultation, teaching and observation, and scientific research summary. This method has the advantages of less trauma, less intraoperative and postoperative pain, thorough surgery, and fine operation. The nasal endoscopic surgery can not only remove rhinitis, sinusitis and nasal polyps completely, but also correct the deviated septum at the same time, thus reducing the recurrence rate after surgery. According to statistics, more than 80% of patients with sinusitis and nasal polyps treated by nasal endoscopic surgery can achieve the purpose of radical cure.
2, nasal endoscopic surgery indications (1) chronic and chronic recurrent sinusitis conservative treatment failed; (2) nasal polyps; (3) mycosis sinusitis; (4) chronic dacryocystitis; (5) nasal cavity, sinus benign tumor removal; (6) nasal cavity, sinus malignant tumor exploration and early nasal cavity, sinus malignant tumor removal; (7) pituitary adenoma removal; (8) cerebrospinal fluid nasal leak transsphenoidal repair; (9) (9) refractory nasal hemostasis; (10) orbital decompression; (11) optic canal decompression; (12) nasal, sinus, intraorbital and skull base foreign body removal, etc. In addition, the application of nasal endoscopic surgery can be extended to nasal neurosurgery or nasal-ocular related surgery.
