Clinical Definition

Nasal valve characteristics:

  • Narrowest Point: Most constricted area of nasal airway
  • Internal/External: Internal and external nasal valve areas
  • Breathing Control: Major site of nasal airflow resistance
  • Collapse Prone: Can collapse during inspiration
  • Surgical Target: Can be addressed with various procedures

Nasal valve collapse or stenosis can cause nasal obstruction, promoting mouth breathing and potentially contributing to sleep apnea.

Etymology & History

The nasal valve has been recognized anatomically with the development of rhinology, with its importance in sleep breathing becoming understood with modern sleep medicine.

Reference Values & Interpretation

Normal Values

Normal nasal valve anatomy should allow adequate nasal airflow without collapse or significant resistance during inspiration.

Abnormal Values

Abnormal nasal valve anatomy includes stenosis, collapse, or structural abnormalities causing nasal obstruction and impaired breathing.

How It's Measured

Nasal valve anatomy is assessed through nasal examination, nasal endoscopy, and sometimes dynamic imaging or pressure measurements.

Role in Diagnosis

Nasal valve assessment is important for identifying treatable causes of nasal obstruction that may contribute to mouth breathing and sleep problems.

Role in Treatment

Nasal valve abnormalities can be treated with medical management, nasal dilators, or surgical procedures to improve nasal breathing.
