What causes a deviated nasal bridge?

A deviated nasal bridge may be caused by congenital factors, acquired trauma, pathological factors, or others. If experiencing discomfort, timely medical consultation is recommended.

During embryonic development, uneven growth of the nasal bones, nasal septal cartilage, or surrounding soft tissues may lead to a deviated nasal bridge. For example, nasal septal deviation often accompanies a deviated nasal bridge; some people are born with this condition, which may be related to genetic factors or environmental influences during pregnancy, such as medication exposure or nutritional deficiencies.

This is one of the main causes of a deviated nasal bridge. External nasal trauma, such as injuries from sports, traffic accidents, or physical altercations, can cause nasal bone fractures, dislocation or twisting of the nasal septal cartilage. If the nasal structures do not heal properly after injury, a deviated nasal bridge may remain. For example, nasal trauma during adolescence that is not promptly treated may gradually become apparent as the individual grows and develops.

Certain diseases may indirectly cause nasal bridge deviation. For instance, intranasal tumors such as hemangiomas or nasal polyps exerting long-term pressure on the nasal septum may cause displacement. Chronic rhinitis or sinusitis causing prolonged inflammation may affect the nasal septal cartilage, leading to structural deformation. Additionally, rare congenital nasal bone malformations may also present with nasal bridge deviation.

A deviated nasal bridge not only affects appearance but may also lead to functional problems such as nasal obstruction, headache, and reduced sense of smell in severe cases. If the deviation is mild and asymptomatic, no immediate treatment may be necessary. However, if the deviation is pronounced or accompanied by symptoms, diagnostic evaluation using nasal bone CT scans, nasal endoscopy, and other tests should be performed to determine the underlying cause. Surgery, such as nasal bone correction, septoplasty, or rhinoplasty, may be required to correct the condition when indicated.
