There are two cavities in the human nose, and they are separated by the nasal septum, which is perpendicular to the frontal plane of the face. In general, the septum of normal people is seldom completely straight, and most of them have different degrees of deviation, and those without obvious deformity and nasal symptoms are called physiological septal deviation, which usually do not need treatment. If the normal physiological dysfunction of the nasal cavity or clinical symptoms such as nasal congestion, headache and nasal bleeding are caused by septal deformity, it is called pathological nasal septal deviation and needs to be treated. Nasal septal deviation is divided into congenital and traumatic, the former is born with the former, the latter is after the injury of foreign blows or masses, foreign body compression. The common symptoms of nasal septal deviation include nasal congestion, nasal bleeding, headache, etc. Among them, nasal congestion is mostly persistent, if it is “C-type” deviation or harsh or short protrusion, it is unilateral nasal congestion, if it is “S”-type deviation, it is bilateral nasal congestion; due to the deviation of the nasal septum Due to the compression of the septum’s eccentric surface or craggy protrusion, the mucous membrane is thinner, and the blood vessels are pressed outwardly and protrude, and the stimulation of breathing air and dust, it is easy to break and bleed; due to the nasal septum’s protruding surface and craggy protrusion, the moment protrusion can cause reflex headache by pressing the turbinates. Therefore, nasal congestion, headache and nasal bleeding are the three major symptoms of nasal septal deviation. Since deviation can also lead to sinusitis, increased purulent secretions in the nasal cavity are also seen. The treatment of nasal septal deviation is mainly surgical. Except for a few patients with complex septal deformity, submucosal resection of nasal septum and septoplasty can achieve good results. However, there are individual patients who can develop postoperative complications, such as nasal septal hematoma, nasal septal perforation and nasal septal abscess. 1. Should I rest at home or can I work after discharge from the hospital? Patients with deviated septum can continue to work after discharge, but they should pay special attention to protect their nose when playing sports such as ball games. 2. How to use medication It is advisable to use compound peppermint oil drops to keep the mucous membrane of nasal septum moist after surgery for patients with deviated nasal septum. Local application of gentamycin eye ointment can also be applied to the anterior part of the nasal cavity. To prevent incisional infection, short-term oral antibiotics can be given. Terfenadine and paracetamol can reduce local allergic reactions. Postoperatively, you can also apply 1 to 2 months of Chinese tablets such as rhinitis tablets. 3.Whether review is needed Patients with deviated nasal septum generally do not need to go to hospital for review after discharge. 4. Diet and living principle Eat more fresh vegetables and fruits and less spicy and fried food. Strengthen physical exercise to reinforce the immunity of the body. Prevent upper respiratory tract infections and epidemic diseases. Avoid playing basketball, boxing, diving and other sports that may hurt the back of the nose.
