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.
Procedure: Vibrissae trimming
Patients will have oxymetazoline administered prior to assessment of outcome measures to ensure minimal impact of erectile mucosal tissue on measurement.
Drug: Application of oxymetazoline
Afrin will be administered to minimize the impact of erectile mucosal tissue on obstruction.
Other Names:
  • Afrin
