Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Nasal Obstruction Procedure: Vibrissae trimming Drug: Application of oxymetazoline Not Applicable

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 60 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: The Effect of Vibrissae on Subjective and Objective Measures of Nasal Obstruction
Study Start Date : May 2013
Actual Primary Completion Date : October 2013
Actual Study Completion Date : October 2013

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 Name: Afrin

Primary Outcome Measures :
  1. Nasal airflow/pressure [ Time Frame: Participants will undergo assessment over a 30 minute period, no follow-up ]
    Objective measures include airflow and pressure as assessed by Rhinomanometry.

  2. Subjective Nasal Obstruction [ Time Frame: Participants will undergo assessment over a 30 minute period, no follow-up ]
    Subjective measures will be assessed via the modified version of the NOSE outcome instrument-a validated test of subjective nasal obstruction
