The use of endoscopy began in the 19th century. 1879 Nitze in Germany first used a cystoscope with a front lighting device, creating a precedent for the use of endoscopy. early 1980s, Austrian scholar Messerklinger founded the nasal endoscopic surgery technique. since the 1990s, China Xu Geng and Han Demin have carried out nasal endoscopic surgery, and spread to the country, and soon in various places rapidly carried out.
The nasal endoscopic equipment includes: 0 degree, 30 degree, 70 degree endoscope, cold light source, guide line, surgical instruments, display system, and nasal power system. Working principle, the light from cold light source enters the nasal endoscope through the guide line to reach the operation or examination area, and the operation is observed through the nasal endoscope or display system.
The procedures that can be performed under the nasal endoscope include sinusitis (including nasal polyps), deviated nasal septum, benign tumors and more limited malignant tumors of the nasal cavity and sinuses, treatment of persistent rhinorrhea, transnasal lacrimal sac rhinostomy, transnasal optic nerve decompression for trauma-induced optic nerve canal fracture, transsphenoidal pituitary tumor resection, repair of cerebrospinal fluid leak, adenoidectomy, etc.
Advantages of nasal endoscopic surgery: operation under direct vision without surgical blind spot, magnification, updating of surgical instruments, surgical concept is more scientific and more in line with physiological functions than before.
