Outcome Measures
Primary Outcomes (9)
Nasal Obstruction Symptom Scale (NOSE) Score
The NOSE survey is a disease-specific questionnaire designed to measure nasal obstruction. It is commonly used in otolaryngology practice to provide an objective measure of nasal obstruction. Patients rate on a 0-4 scale questions regarding congestion, ability to get air in nose during exercise, and others. Scores result in symptom severity classes of mild, moderate, severe or extreme NAO.
Jan 2013 - Dec 2025
22-Item Sinonasal Nasal Outcome Test (SNOT-22)
The The Sino-Nasal Outcome Test (SNOT-22) Questionnaire is a validated patient-reported outcome measure established to delineate the presence and severity of sinonasal disorders. It is a widely used questionnaire for assessing the impact of chronic rhinosinusitis on a patient's quality of life. Minimum possible score: 0; Maximum possible score: 110. Higher scores indicate: A worse outcome, meaning more severe symptoms and a greater negative impact on quality of life.
Jan 2013 - Dec 2025
Standard Cosmesis and Health Outcomes Survey (SCHNOS)
The SCHNOS survey is a validated 10-item survey with two-domains (nasal obstruction and nasal cosmesis) patient-reported outcomes survey designed to evaluate both functional and cosmetic components of rhinoplasty. Minimum possible score: 0, Maximum possible score: 40. Higher scores indicate: A better outcome, meaning improved nasal function and cosmesis.
Jan 2013 - Dec 2025
Short Form-12 (SF-12 version 1)
SF-12 is a 12 question self-reported outcome measure assessing the impact of health on an individual's everyday life. It includes questions in 8 domains: limitations in physical activities due to health problems, limitations in social activities because of physical or emotional problems, limitations on usual role activities because of physical or emotional health problems, bodily pain, general mental health, vitality, and general health perceptions. A score above 50 indicates better than average health-related quality of life and scores less than 50 suggest below-average health. Minimum possible score: 0, Maximum possible score: 100. Higher scores indicate: A better outcome, meaning improved health-related quality of life
Jan 2013 - Dec 2025
Mini-Rhinoconjunctivitis Quality of Life Score (Mini-RQLQ)
The mini-RQLQ is a self-administered questionnaire that measures functional impairments that are most troublesome to adult patients because of their rhinoconjunctivitis. This instrument has 14 questions in 5 domains: activity limitation, practical problems, nose symptoms, eye symptoms and non-nose/eye symptoms). Minimum possible score: 0, Maximum possible score: 42. Higher scores indicate: A worse outcome, meaning more severe symptoms and a greater negative impact on quality of life.
Jan 2013- Dec 2025
Epworth Sleepiness Scale (ESS)
The ESS is a validated widely used self-administered screening questionnaire that evaluates excessive daytime sleepiness.
