Nasal sinus diseases are common and multi-infarct, and the traditional surgical methods of nasal sinus in the past are as follows: maxillary sinus radical surgery, lateral nasal incision, etc. all need to go through the lipogingival groove or facial incision, which is traumatic and has facial scars, bleeding, and patients are very painful. Due to the limitations of the operation, the lesion is often not completely removed and the recurrence rate is high.
At present, nasal endoscopic surgery has been widely used for: chronic sinusitis, nasal polyps, rhinorrhea, hypertrophic rhinitis, nasal septal malformation, sinus cyst, congenital posterior nostril atresia, nasal sinus foreign bodies, benign tumors and more limited malignant tumors.
With the support of optical system and surveillance system, nasal endoscopy and special surgical instruments are used to perform nasal, sinus, orbital and skull base surgeries through nasal approach, which has become the main technique of nasal surgery system. Its advantages are obvious: less trauma, less bleeding, shorter time, precise operation, less pain for patients, fast recovery and high cure; avoiding craniotomy and facial incision, such as cerebrospinal fluid nasal leak repair, pituitary tumor removal, optic nerve decompression, tear sac nasal opening and other minimally invasive surgery.
