Background
Currently, stents can be used to hold, open or enlarge body structures such as veins, arteries, ureters, urethra, hollow body organs, nasal passages, sinus cavities, and the like. The nasal cavity is internally provided with a plurality of folds, the shape is changeable, the individual difference is very large, and after the pathological changes caused by diseases, the complexity of the internal space of the nasal cavity is further increased.
The chronic nasal sinus lesions such as chronic nasosinusitis nasal polyp have extremely high incidence rate, and the operation is one of the main treatment means. With the development of medical technology, transnasal endoscopic nasal sinus surgery has become a mainstream. The operation is a better treatment method, but the recovery of nasal cavity and nasal sinus functions after operation requires a certain time and has a certain difference in effect. This is due in part to the effects of the specific pathophysiological mechanisms of nasal science, which require prolonged (typically 2-3 months) medication and follow-up treatments after surgery. On the other hand, in the narrow space of the nasal cavity, any operation and treatment are difficult, and the nasal cavity adhesion is easily caused, so that the related complications are secondary. The two are usually causal, which increases the difficulty in the nasal endoscopic surgery.
