Deviated septum correction is performed under general anesthesia and is usually performed endoscopically to remove the deviated septal cartilage. The mucous membrane of the left septum is incised first, and at the same time, it is peeled off with a peeler to exceed the deviated septum, then the septal cartilage is incised, and at the same time, the mucous membrane of the opposite septum is peeled off to exceed the deviated septum as well, and the deviated septal cartilage is removed, and then the septum is centered by aligned sutures, and the surgery is completed. This disease exists in 90% of patients, mainly due to septal deviation caused by poor development of the nasal septum during fetal life, acquired trauma or compression by nasal tumors, which will cause bilateral nasal congestion, headache, decreased sense of smell, yellow nasal discharge and other related symptoms. In the treatment, it is necessary to choose the nasal septum deviation correction to carry out, after the operation, patients need to apply antibiotics to avoid local infection, about one week can be cured and discharged from the hospital.
