Association Between Nasal Septal Deviation and Estimated Pulmonary Artery Pressures-Scoping Review

Samuel A Collazo et al. Clin Otolaryngol. .

Abstract

Objective: Nasal septal deviation (NSD) is a common cause of chronic upper airway obstruction (UAO), and surgical correction via nasal septoplasty results in improvements in airflow. Multiple studies have been conducted to assess possible relationships between chronic UAO (including due to NSD) and cardiorespiratory function (such as pulmonary artery pressures). The objective of this scoping review is to identify and examine the current evidence on the potential relationship between nasal septal deviation, estimated mean pulmonary artery pressure (mPAP), and estimated pulmonary artery systolic pressure (ePASP) in patients who undergo nasal septoplasty.

Data sources: PubMed, EMBASE, Ovid.

Methods: A scoping review was performed in accordance with the PRISMA Extension for Scoping Reviews guidelines.

Results: Two independent reviewers screened 411 articles; 9 before-after studies met eligibility criteria for review inclusion. There was a total of 458 study participants, of which 395 underwent septoplasty and 63 were matched controls. All studies reported a statistically significant decrease between the pre-operative and post-operative estimated mPAP (p < 0.05) and/or ePASP (p < 0.001) in subjects who underwent nasal septoplasty. Two studies included control participants and reported a statistically significant difference between the pre-operative estimated mPAP of patients with NSD and controls (p < 0.001).

Conclusion: This scoping review highlights the current evidence on the potential relationship between NSD, estimated mPAP, and ePASP in patients who undergo nasal septoplasty for NSD. Further studies of higher statistical and methodological quality are required to assess for cause-and-effect relationships and examine the potential link between chronic UAO and cardiorespiratory function.

Keywords: mean pulmonary artery pressure; nasal septal deviation; nasal septoplasty; pulmonary artery systolic pressure.
