Nasal Obstruction Evaluation After LeFort I Osteotomy: A Pilot Study

Previous literature has documented changes in nasal obstruction after acute LeFort I osteotomy. However, there is a paucity of studies that evaluate distraction-mediated LeFort I (DO-LFI) without concomitant intranasal interventions using the nasal obstruction symptom evaluation (NOSE) scale in Class III patients. The purpose of this study is to objectively evaluate nasal obstruction quality of life through the NOSE scale in patients undergoing DO-LFI. Inclusion into the study required both a preoperative (1 year <= date of service) and postoperative (>= 6 months and <= 2 years) NOSE scale administration. Nasal obstruction symptom evaluation scales were compared using Wilcoxon signed rank test. There was a significant difference in composite NOSE scales, x? = 8.0 (interquartile range: 4.0-11.0), x? = 1.0 (interquartile range: 1.0-3.0), P < 0.017, preoperatively and postoperatively respectfully. Additionally, when looking at individual components of the NOSE scale, nasal congestion or stuffiness, and trouble breathing through nose were significantly improved after DO-LFI (P < 0.017). Nasal blockage or obstruction (P > 0.084) and trouble breathing when exercising (P > 0.076) trended towards significant improvement, as well. Trouble sleeping did not differ, P > 0.611. We elucidate, in this pilot study, that there is an association between DO-LFI and patient reported nasal obstructive symptoms. Future prospective studies utilizing the NOSE scale are needed to determine causality.
