Brief introduction of nasal endoscope

Nasal endoscope, a minimally invasive medical examination instrument, has good lighting. Through the matching surgical instruments, the operation can be more detailed and can reach areas that traditional surgery can't reach. The angle ranges from 0 to 120 degrees. The common nasal endoscope is a kind of rigid bronchoscope, which is different from fiberoptic laryngoscope and fiberoptic esophagoscope.

Nasal endoscope is a functional operation that keeps the normal mucosa and structure of nasal cavity and paranasal sinuses as much as possible, forms good ventilation and drainage, and promotes the good recovery of the morphology and physiological functions of nasal cavity and paranasal sinuses with the help of electronic endoscope and supporting surgical instruments. At the same time, according to the severity of the lesion, the purpose of curing rhinitis, sinusitis and nasal polyps can be achieved by restoring the physiological functions of nasal cavity and paranasal sinuses. Because of its strong light conductivity, multi-angle and large field of vision, it can directly peep at many important parts of the nasal cavity (such as various ostia, various grooves and hidden stenosis in the sinus) and subtle lesions in the nasopharynx, thus reducing the postoperative recurrence rate.
