A Study of the Effect of Nasal Hair on Nasal Obstruction


About this study

The purpose of this study is to assess the subjective and objective effects that nasal hair has on nasal obstruction. Many studies have been performed measuring and describing the impact of a number of factors on symptoms of nasal obstruction, including anatomical, neoplastic, infectious, and inflammatory causes. Despite this scrutiny, no attention has been paid to the nasal hairs as a potential anatomical contributor to nasal obstruction. .

More information


  • Large particles entering the nose are collected by nasal hair present in the anterior nares. Increased hair density provides an improvement in the filtering efficiency of the nose, while reduced amounts of nasal hair cause a decrease in its efficiency. The amount of nasal hair can vary between individuals, which can make a difference in the filtering efficiency of the nose. Reduced filter function of the nose leads to increased exposure of the airways to allergens. The aim of this study was to determine the effect of nasal hair density on the risk of developing asthma in seasonal rhinitis (SR) patients. Read More on PubMed
