The Effect of Nasal Hair on Nasal Obstruction

April 19, 2019 updated by: Grant S. Hamilton, III, Mayo Clinic

The Effect of Vibrissae on Subjective and Objective Measures of Nasal Obstruction

Nasal obstruction is a common complaint prompting presentation to an otolaryngologist. Many studies have been performed quantifying 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 vibrissae as a potential anatomical contributor to nasal obstruction. The proposed study intends to elucidate that contribution, if any exists.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Vibrissae trimming
Patients will serve as their own control, with assessment of primary outcomes pre- and post-trimming of vibrissae.
Patients will have oxymetazoline administered prior to assessment of outcome measures to ensure minimal impact of erectile mucosal tissue on measurement.
Afrin will be administered to minimize the impact of erectile mucosal tissue on obstruction.
Other Names:
  • Afrin
