The actual nasal disease is a very important part of your life. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. Viral infection is the primary cause, initially manifested as dryness, burning or itching in the nose and sneezing, followed by nasal congestion, watery nasal discharge, reduced sense of smell and occlusive nasal sounds, followed by bacterial infection with pus, which may be accompanied by headache and fever. Chronic rhinitis is a chronic inflammatory disease of the mucous membrane and submucous layer of the nasal cavity. Clinical manifestations are characterized by swelling of the nasal mucosa, increased secretions, no clear-cut pathogenic microbial infection, and a disease that lasts more than a few months or has recurrent episodes. Chronic rhinitis is a common disease, mostly caused by recurrent episodes of acute rhinitis or by inappropriate nasal medication. It is characterized by occlusion, headache, dizziness, occlusive nasal sounds and decreased sense of smell. Examination mostly reveals congestion of the nasal mucosa and swelling of the inferior turbinates. Sinus radiographs are normal. Sinusitis is a purulent inflammation of the mucosa of the sinuses, mainly manifested by nasal congestion, pus (foul odor), headache or local pain. Sinus radiographs show chronic mucosal hypertrophy in the sinuses bilaterally, or purulent fluid planes. Sinusitis is inevitably combined with rhinitis, and the pathogenesis and pathophysiological processes of both are identical and mutually reinforcing. In recent years the name of sinusitis has been changed to rhinosinusitis. The sinuses are divided into four pairs of sinus cavities: maxillary sinus, sieve sinus, frontal sinus, butterfly sinus, of which maxillary sinusitis is the most common, can be limited to one sinus, but also can be the onset of multiple sinuses, or even the whole group of sinuses onset, maxillary sinusitis is mostly forehead headache in the afternoon, the former group of sieve sinusitis is similar to maxillary sinusitis, the latter group of sieve sinusitis is similar to butterfly sinusitis, frontal sinusitis is mostly headache in the morning, relieved in the afternoon, butterfly sinusitis is mostly deep eye or occipital pain in the morning light afternoon heavy. Acute rhinitis anti-cold treatment more well cured, chronic rhinitis more inferior turbinate mucosa of laser, partial excision, inferior turbinate of the external fold treatment more well. Sinusitis is more complicated, sinusitis sinus opening is small, the nasal passage is narrow and tortuous, easy to block, causing obstruction of sinus ventilation and drainage. In recent years, it is believed that the obstruction of drainage and ventilation of the sinus opening and adjacent nasal passages is the most important mechanism for the development of sinusitis. Functional nasal endoscopic surgery and based on the above theory, the purpose of curing sinusitis can be achieved through surgery to maintain permanent drainage and ventilation of the sinus orifices and adjacent nasal passages. Nowadays, nasal endoscopic surgery technology has been widely developed in China, and nasal endoscopic surgery with chronic sinusitis and nasal polyps as the main treatment objects has promoted the diagnosis and treatment level of many diseases in otorhinolaryngology-head and neck surgery, and also promoted the research of related anatomy, pathophysiology, imaging and other disciplines to make new progress, and the connotation of this technology is richer, and the application scope is constantly extended, and the disease has to some extent updated the ophthalmology and cranial surgery. To a certain extent, it has updated the treatment tools of ophthalmology and skull base surgery and promoted the further development of the discipline as a whole. At the same time, the majority of patients benefit.
