Measurement and quantification of cadaveric nasal hairs

Abstract

Measurement and quantification of cadaveric nasal hairsDear Editor, Nasal hairs, known as vibrissae, serve as a filtration system to prevent particles larger than 3 µm from passing through the nasal cavity. 1,2 Patients with alopecia areata (AA) often have associated loss of vibrissae, resulting in vasomotor discomfort and rhinitis, and are at hypothetical risk for increased inhalation exposure to environmental allergenic and infectious aerosolized particles. 3 Surprisingly, there is no evidence in literature on any anatomic description of human nasal vibrissae characteristics.
