Introduction
Septal deviation is common in the general population; most individuals exhibit some degree of nasal septal deviation. This condition typically arises from uneven growth and development of the cartilage and bone components comprising the nasal septum during maturation.
When septal deviation is present, it can be visualized more clearly by the physician during direct examination.
If symptoms are attributable to septal deviation, the deviated side of the nasal cavity should be stabilized and occluded, and surgical intervention should be considered.
A well-defined nose enhances the three-dimensional appearance of the facial features. However, a deviated nasal septum can significantly diminish facial aesthetics. What exactly is a deviated nasal septum?
What Is a Deviated Nasal Septum?
Nasal septal deviation is common in the general population. It typically arises from uneven growth and development of the cartilage and bone components comprising the nasal septum during maturation. When present, a deviated septum is readily identifiable upon direct clinical examination by a physician. If symptoms are attributable to septal deviation, the affected side of the nasal cavity may be temporarily stabilized and occluded, and surgical correction should be considered.
Septal deviation is primarily congenital—resulting from abnormal embryonic or postnatal development—or acquired following nasal trauma. Many individuals have a mildly deviated septum without experiencing any symptoms or functional impairment; this is termed a “physiological deviation” and generally requires no specific intervention. However, if the deviation causes clinically significant symptoms—such as persistent nasal obstruction, recurrent epistaxis, or frequent reflexive headaches—patients who have not received systematic treatment may be candidates for submucosal septal correction surgery.
The nasal septum is a normal, essential anatomical structure within the nasal cavity. Its integrity is critical for maintaining nasal structural support. High-septal perforation may lead to external nasal collapse, resulting in a “saddle nose” deformity; anterior septal deviation may cause nasal obstruction. Normal nasal resistance is a prerequisite for efficient alveolar gas exchange. We hope this information has been helpful.
