Nasal polyps are hypertrophic and extremely edematous nasal mucosal tissues that occur in the sieve sinus, maxillary sinus, middle nasal passage, middle turbinate and sieve follicle. It mainly originates from the mucosa of the middle nasal passage and sinuses, and protrudes into the nasal cavity and sinus cavity, with the appearance of translucent lychee-like neoplasm with smooth surface. It may be a solitary pedunculated polyp, or it may accompany chronic sinusitis.
The surgical procedure for chronic sinusitis with nasal polyps is generally as follows:
After general anesthesia is completed, epinephrine saline swabs are used to constrict the nasal mucosa in the operated area. 0 degree nasal endoscopy is performed using polyp forceps to clip some polyp tissue for pathological examination. Nasal power system was used to suction and cut the polyp tissues, and complete resection was performed after revealing the hooked process, opening the sieve follicle, anterior sieve sinus, posterior sieve sinus, removing part of the upper turbinate, exposing the pterygoid sieve fossa, and opening up and enlarging the opening of the pterygoid sinus.
Under 70-degree nasal endoscopy, the maxillary sinus opening was examined to be mostly obstructed with polyp tissue, the maxillary sinus opening was explored, and the sinus opening was enlarged appropriately to clear the secretions in the maxillary sinus. Open the nasal mound airspace, open the frontal crypt, open and explore the frontal sinus.
Remove residual bone fragments and polypoid tissue in the operative area. After examination and complete hemostasis, a biodegradable glucocorticoid stent can be placed in the operative area, filled with nanoabsorbent cotton and tumescent hemostatic material.
The single clipped nasal polyp can be removed intact from the tip by endonasal endoscopy.
If you need to know more about the different types of nasal polyps, you can bring your own sinus CT films and endoscopic examination results to a regular hospital and ask for a specialist’s opinion.
