There are two etiologies for nasal skew in general cases: First, due to local trauma. Second, nasal trauma caused by tumors in the nasal cavity, which is usually common in direct impact injuries, can cause nasal bridge deviation, nasal congestion, nasal bleeding, headache and other related symptoms. During the examination, the nasal bridge can be seen to be deviated to one side, and collapse can be seen in the middle of the nasal bridge or the root of the nose. During the examination, the mucous membrane of the nasal cavity can be seen to be congested and edematous bilaterally, but bloody secretions can be seen in the lower nasal passage. Patients need to undergo nasal fracture reconstruction within one week, and they can be discharged from the hospital in about one week. Otonasal tumors are commonly found in nasal polyps, nasal fibers, hemangiomas, and malignant tumors of the nasal cavity, and abnormal new organisms will be found in the unilateral nasal cavity. In the case of benign tumors, they are usually soft, painless, and do not bleed easily. If it is a malignant tumor, it often has a cauliflower-like change with a yellow discharge covering the surface. When the tumor is large, it will cause the nose to deviate to one side. In terms of treatment, nasal tumor requires local pathology and then surgery, radiotherapy and chemotherapy after the diagnosis is confirmed.
