Which test is used to evaluate nasal valve patency?

• A. Cottle test
• B. Sneezing test
• C. Rhinomanometry
• D. Nasal endoscopy

Answer: (A)

The Cottle test is specifically designed to assess the patency of the nasal valve, which is a critical area for airflow in the nasal passages. During the Cottle test, the examiner lightly pulls on the lateral aspect of the nose, thereby widening the nasal valve area. If this maneuver improves the patient's airflow, it indicates that the nasal valve was previously compromised, suggesting that the obstruction may be related to the structural configuration of the nasal passages rather than other issues such as inflammation or mass lesions. This test is particularly relevant in patients with nasal breathing difficulties, as it helps clinicians identify whether interventions should focus on structural modifications, such as turbinate reduction or spreader grafting, to enhance nasal airflow. While other mentioned tests, such as rhinomanometry and nasal endoscopy, can provide valuable information about nasal function and anatomy, the Cottle test specifically isolates the nasal valve region's functionality and directly relates to evaluating its patency.
