Clinical Definition

Nasal septum characteristics:

  • Dividing Structure: Separates left and right nasal cavities
  • Cartilage and Bone: Anterior cartilage, posterior bone (vomer and ethmoid)
  • Midline Position: Ideally straight in the center
  • Airflow Direction: Influences nasal breathing patterns
  • Common Deviation: Often deviated in normal population

A deviated nasal septum can cause unilateral or bilateral nasal obstruction, promoting mouth breathing and potentially contributing to sleep apnea.

Etymology & History

The nasal septum has been recognized anatomically since ancient times, with its role in breathing disorders becoming understood with the development of rhinology and sleep medicine.

Reference Values & Interpretation

Normal Values

Normal nasal septum anatomy should be relatively straight and centered, allowing balanced airflow through both nasal cavities.

Abnormal Values

Abnormal nasal septum anatomy includes deviation that can cause significant unilateral or bilateral nasal obstruction and promote mouth breathing.

How It's Measured

Nasal septum anatomy is assessed through physical examination, nasal endoscopy, and CT imaging to evaluate deviation and obstruction severity.

Role in Diagnosis

Nasal septum assessment is important for identifying nasal obstruction that may contribute to mouth breathing and sleep-disordered breathing.

Role in Treatment

Nasal septum deviation can be treated with septoplasty to improve nasal breathing, which may help with CPAP tolerance and overall sleep quality.
