Why can nasal septum deviation cause sinusitis?

The nose consists of three parts: nose, nasal cavity and sinuses. The nasal cavity is divided into two parts by a layer of partition, which is the nasal septum and is very thin. It is easily deflected by external forces. When a person's nasal septum deflects, due to the degree and position of deflection, it is easy to produce cold symptoms such as stuffy nose, runny nose and headache. If the deviated part compresses the inferior turbinate or middle turbinate, it can cause reflex headache; At the same time, the high level often blocks the sinus drainage, hinders the sinus drainage, and can induce sinusitis. In addition, due to nasal congestion, breathing is not smooth, and air stays in the nasal cavity for too long, resulting in air flow staying in the nasal cavity, and the nasal cavity itself has bacteria and viruses. Once the virus and bacteria multiply, it is easy to catch a cold and upper respiratory tract infection, which will induce sinusitis. How does nasal septum deviation cause sinusitis? According to the actual situation of patients, we should control sinusitis first, and then decide whether to correct nasal septum deviation surgically according to whether the headache symptoms are relieved after sinusitis control. Deviation of nasal septum has three major symptoms: nasal congestion, nosebleeds and snoring during sleep. There are generally no symptoms, don't worry, but if there are symptoms, you need surgery to correct them. """"Is the operation of deviated nasal septum safe?
