[Effect of the external nasal dilator breathe right and nasal cycle influence].
The external nasal dilator Breathe Right is a nonprescription disposable mechanical device worn over the bridge of the nose that supports the outer walls of the nasal vestibule to increase cross-sectional nasal valve area and enhance air flow through the nose. When worn, the device applies a gentle outward pull to the outside walls of the nasal vestibule that helps prevent collapse of the lateral walls of the nasal vestibule. The device appears similar to an adhesive bandage with two polyester springs attached lengthwise to the nonadhesive side of the backing material. ⋯ Interestingly, the change in the C-notch decreased gradually with time. One possible mechanism may be the change in compliance between the skin under the Breathe Right and the nasal mucous membrane. The nasal cycle did not significantly influence the effect of Breathe Right.
