What are the advantages of nasal endoscopic surgery Nasal endoscopic surgery is also known as functional endoscopic surgery. It can make the surgery more delicate by the good illumination of the nasal endoscope and the supporting surgical instruments; it changes 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 complete removal of the 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, 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 can be directly visualized. 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.
Indications for nasal endoscopic surgery 1. chronic and chronic recurrent sinusitis who have failed conservative treatment; 2. nasal polyps; 3. mycosis fungoides; 4. chronic dacryocystitis; 5. nasal cavity and sinus benign tumor excision; 6. nasal cavity and sinus malignant tumor exploration; 7. pituitary adenoma excision; 8. cerebrospinal fluid nasal leak transnasal repair; 9. nasal hemostasis; 10. orbital decompression; 11. optic nerve canal decompression; 12. The use of nasal endoscopy has been applied to the removal of foreign bodies from the nose, sinuses, orbit and skull base.
In addition, the application of nasal endoscopic surgery can be extended to the field of nasal neurosurgery or nasal-ocular related surgery.
Nasal endoscopic surgery for rhinitis and sinusitis Due to the slow progress of research on the physiological functions of the nasal cavity and sinuses, coupled with deep sinus sites and no breakthrough in visual equipment research, sinus surgery has not been significantly improved for a long time. In the past, the traditional sinus surgery, i.e., the radical treatment of removing most of the middle turbinates and scraping all the mucous membrane in the sinuses, was often used for patients with more severe disease, but this type of surgery is destructive.
In 1966, Germany made a telescopic rigid straight nasal endoscope based on the theory of columnar mirror and combined with cold light source system on a trial basis, which has the advantages of wide field of view and strong light guiding ability. In the early 1970s, Austrian rhinologists pioneered a new field of transnasal endoscopic sinus surgery, i.e., through various angles of the endoscope, lesions in the hidden parts of the sinuses could be completely removed. This technique was introduced to China in the early 1980s and has now become a comprehensive minimally invasive surgical technique widely used in otorhinolaryngology, head and neck surgery. The surgical operation is performed in the nostrils without incisions on the nasal face, which is a surgical technique that can get rid of diseases while preserving normal physiological functions, and can be said to be one of the most important advances in rhinology technology in the last century.
