Evaluation of functional rhinoplasty using the Modified Cottle test in Asian patients.

Abstract

CONCLUSION:

MCT is a useful tool to pre-operatively determine whether internal nasal valve (INV) narrowing affects a nasal obstruction. Functional rhinoplasty seemed to produce better results than septoplasty in Asian patients with a nasal obstruction, due to INV narrowing.

OBJECTIVE:

This study compared pre-operative modified Cottle test (MCT) findings and post-operative clinical improvement according to surgical approach in an Asian population.

METHODS:

One-hundred and sixty-four patients who underwent septal surgery were enrolled. The clinical symptoms, radiological findings, and paranasal computed tomography (PNS CT) scan results were compared and analyzed between the MCT-positive and -negative groups, focusing on internal nasal valve narrowing. Post-operative clinical improvement were also compared based on whether septoplasty or functional rhinoplasty was performed.

RESULTS:

The MCT-positive group had significantly higher pre-operative visual analog scale scores for nasal obstruction and rhinorrhea than those in the negative group. The MCT-positive group had a significantly higher percentage of highly deviated septa on PNS CT and endoscopic findings than those in the MCT-negative group. The functional rhinoplasty group had a significantly higher MCT conversion rate (positive to negative) and improvement in nasal obstruction than those in the septoplasty group.
