Deviated septum surgery is usually painless during the operation, but there may be discomfort after the operation if nasal tamponade is taken. 1. Intraoperative: Deviated septum surgery is performed under general anesthesia, and the patient has no obvious feeling. At the same time, the surgery is minimally invasive, less traumatic to the local skin, and can achieve rapid improvement of the results, so most do not feel pain. 2. Postoperative: Some of the deviated nasal septum surgeries adopt expanding sponge or Vaseline gauze stuffing to stop bleeding, which may cause the patient to experience nasal distension, headache, tearing and other discomforts. The discomfort can be relieved after the nasal filler is removed. However, some deviated septum surgeries are performed by suturing the mucous membrane of the nasal septum to avoid the discomfort of postoperative stuffing, which is usually not painful. In summary, deviated septum surgery is mostly painless, but it is an invasive procedure and there may still be some discomfort.
