Predictors of Nasal Obstruction: Quantification and Assessment Using Multiple Grading Scales.

Area of Science:

• Otolaryngology
• Rhinology
• Symptomology

Background:

• Nasal obstruction significantly impacts quality of life.
• Identifying predictors of nasal obstruction severity is crucial for effective management.

Purpose of the Study:

• To evaluate associations between nasal obstruction and demographic factors, medical history, physical tests, and nasal exam findings.
• To identify independent predictors of high Nasal Obstruction Symptom Evaluation (NOSE) scores.

Main Methods:

• Retrospective chart review of 240 patients at a tertiary medical center.
• Univariate and multivariate analyses were performed to assess correlations with NOSE scores and Nasal Obstruction Visual Analog Scale (NO-VAS).

Main Results:

• Allergic rhinitis, external nasal deformity (grades 2-4), and NO-VAS score ≥50 were independent predictors of high NOSE scores.
• History of nasal trauma, use of nasal steroids, internal nasal septal deviation, and narrow nasal valve angle were associated with higher NOSE scores on univariate analysis.
• Inferior turbinate size was not associated with NOSE scores or NO-VAS.

Conclusions:

• Allergic rhinitis, significant external nasal deformity, and a high NO-VAS score are key independent predictors of severe nasal obstruction.
• These findings can aid in clinical assessment and treatment prioritization for patients with nasal obstruction.
