Nasal valve evaluation in the Mexican-Hispanic (mestizo) nose.

Background: Our aim in this study was to determine the angle of the internal nasal valve in Mexican patients with the "mestizo nose" feature and without nasal obstructive symptoms. The work was prospective, comparative, and observational in nature and included patients >14 years of age who were seen in the Otolaryngology Department at the Los Angeles Lomas Hospital between April and May 2016.

Methods: The angle of the internal nasal valve was measured in 30 patients without obstructive symptoms.
