Currently, the correction of a deviated nasal septum is mainly done through surgery. However, for some patients, if the deviation is mild and without symptoms, surgery may not be necessary. Surgery for deviated nasal septum is considered only if the deviation is severe and accompanied by significant clinical symptoms. Presently, minimally invasive surgery under endoscopy, which may involve partial removal of cartilage or septal cartilage reshaping, is a common procedure in otolaryngology. The results are generally reliable and, although there are risks, they are not considered excessively high. Typically, tertiary hospitals with an otolaryngology department can perform this surgery.
