If you don't think it's a big deal, you're wrong. If you don't treat sinusitis in time, it will do great harm to the patients. This is because the nasal cavity and sinuses are located under the brain, above the throat and mouth, between the two eyes, and they are close to each other.
The pathological changes of nasal cavity and sinuses often spread to the nearby tissues, which will cause various complications. If it extends to the brain, it can cause serious death. The infiltration of throat and orbit will also cause various diseases, especially for children. Complications will affect the development of body and intelligence. There are many ways to cause complications of rhinitis and sinusitis
1. Blood infection: the nasal cavity and paranasal sinuses are rich in vascular networks, and have complex connections with the orbital and intracranial, so the bacteria and toxins of rhinitis and paranasal sinusitis destroy the intima of blood vessels to form thrombus, and the thrombus spreads to other organs along with the blood flow, causing complications.
2. Direct infection: the nasal cavity is directly connected with the mouth, throat, lower respiratory tract and digestive tract. The secretion of rhinitis and nasosinusitis is drained down, which directly stimulates these tissues and causes various diseases.
3. Infection by destroying the bone wall: if sinusitis destroys the bone wall of the sinuses, the inflammation often extends to other tissues. Because the position of the sinuses is different, the complications are also different. For example, frontal sinusitis is easy to cause orbital or intracranial complications; ethmoid sinusitis destroys the top wall, invades the anterior cranial fossa, penetrates the side wall, and produces orbital complications. Sphenoid sinusitis can cause different complications in the brain and retrobulbar optic neuritis. Maxillary sinusitis can cause orbital infection and alveolar stenosis.
