After deviated septum surgery, it is possible to sleep on the side and on the back. 1. After surgery, patients need to open their mouths to assist breathing, so the sleeping position has no effect on the condition, but lying flat is better than lying on the side, because the nasal cavity needs to be filled with hemostatic sponges after surgery, and sleeping on the side may have a sense of compression. 2. The wound has not yet healed after the operation, so be careful not to squeeze the nose when you sleep, so as not to cause wound infection. If the patient is local anesthesia, after the deviated septum surgery should be used cold ice on the nose, to prevent the wound blood vessels bleeding. If the patient is under general anesthesia, it is necessary to prohibit eating, drinking and tilting the head to one side as much as possible for six hours to promote the discharge of secretions from the mouth. If there are obvious discomfort symptoms after the deviated septum surgery, it is recommended that the patient go to the hospital as soon as possible for review, and under the guidance of the doctor to carry out scientific and effective treatment.
