Butterfly sinusitis is a kind of sinusitis, which is a common and frequent disease in ENT, and can achieve good results after timely treatment. Therefore, it is not a serious disease, so please do not be overly nervous and anxious. The sinuses of the human body are divided into four groups: the maxillary sinus, the sieve sinus, the frontal sinus, and the pterygoid sinus, of which the pterygoid sinus is located relatively far back, at the base of the human skull. If the butterfly sinusitis recurs, there will be obvious headache, head swelling and discomfort. This condition can be treated with anti-inflammatory drugs for anti-inflammatory treatment, and also with topical glucocorticoid nasal spray to improve the drainage of the pterygoid sinus. If the effect of conservative treatment is not obvious, minimally invasive nasal endoscopic surgery can also be used to open the sinuses.
