Estimation of Nasal and Oronasal Spirometry in Deviated Nasal Septum and Obstructive Sleep Apnea

Abstract

Background: Deviated Nasal Septum (DNS) and Obstructive Sleep Apnea (OSA) makes breathing difficult. If it is not appropriately treated, it may result in defective cognition, work performance may worsen and diminution in health-related quality of life. Aim and Objectives: To find out the significant difference between oronasal and nasal spirometry among DNS and OSA individuals. Material and Methods: Total participants were divided into three groups: Group 1: control, Group 2: DNS and Group 3: OSA. Each group consisted of 150 participants. Two sets of measurements were obtained from each subject i.e. oronasal and nasal spirometry methods. All the data were expressed as mean ± standard error. The means were analysed by One-way Analysis of Variance (ANOVA) with multiple comparison test of Student Newman Keul's test. Results: For eight parameters except for Forced Expiratory Volume in 1 second (FEV1%) and Forced Expiratory Time (FET), Oronasal (O) spirometry vs Nasal (N) spirometry were significantly different with nasal values being less than oronasal values. For the same eight parameters, in both DNS and OSA groups, the following results were found. (i) O values were less than that for control groups. (ii) N values were less than that for control groups. (iii) In both experimental groups, nasal spirometry values were less than oronasal spirometry values. Conclusion: Nasal FET was increased in both OSA and DNS than oronasal FET. Since it is a simple procedure and does not involve any radiological and endoscopy procedure, FET could be an ideal method for assessing nose nasopharyngeal obstruction.
