Introduction
In general, deviated nasal septum may be caused by congenital uneven development of bone and cartilage, short nasal columella causing traction, chronic rhinitis, nasal polyps, or nasal trauma. If discomfort symptoms occur, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. In daily life, maintain nasal hygiene and avoid frequent nose picking; take protective measures when going outdoors to reduce the risk of nasal injury.
Under normal circumstances, nasal septum deviation may be caused by factors such as congenital uneven development of bone and cartilage, short columella pulling the septum, chronic rhinitis, nasal polyps, or sinus trauma. If discomfort symptoms occur, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Specific causes are analyzed as follows:
1. Congenital Uneven Development of Bone and Cartilage
During the embryonic stage or puberty, asynchronous development of the nasal septal bone and cartilage—when one side grows faster than the other—can compress the opposite side and lead to deviation. In adults without significant symptoms, observation is acceptable. Avoid aggressive nose picking and minimize nasal irritation in daily life.
2. Short Columella with Traction
Poor development and an overly short columella can pull on the anterior-inferior portion of the nasal septum, causing it to deviate from the midline. This can be corrected surgically through columellar lengthening. After surgery, keep the nasal area clean and dry, and avoid impact or trauma.
3. Chronic Rhinitis
Long-term inflammation of the nasal mucosa can cause mucosal swelling that persistently presses against the nasal septum, leading to deformation. Follow your doctor’s instructions for using medications such as budesonide nasal spray, mometasone furoate nasal spray, and Tongqiao Biyan tablets. Also avoid dusty environments and exposure to irritating gases.
4. Nasal Polyps
As nasal polyps gradually enlarge, they can push the nasal septum toward the opposite side, causing displacement. Under medical guidance, medications such as prednisone acetate tablets, eucalyptus citronellal enteric soft capsules, and Biyuan Tongqiao granules may be used. If drug therapy proves ineffective, endoscopic nasal polyp removal surgery may be required.
5. Sinus Trauma
After nasal impact or fracture, improper realignment of the nasal septal bone and cartilage can result in deviation. Prompt medical attention is necessary, and septoplasty may be performed. After surgery, avoid strenuous physical activity and refrain from forceful nose blowing.
In daily life, maintain good nasal hygiene and avoid frequent nose picking; take protective measures when outdoors to reduce the risk of nasal injury; actively treat nasal inflammatory conditions to prevent chronic progression; and undergo regular nasal examinations for early detection and intervention.
