Relation between grades of acquired nasopharyngeal stenosis and severity of obstructive sleep apnea symptoms

Abstract Background Nasopharyngeal stenosis (NPS) is a rare condition defined as the obstruction of communication between oropharynx and nasopharynx owing to scar contracture soft palate, tonsillar pillars, posterior pharyngeal wall. NPS could be primary (attributed disease process such rhinoscleroma) or secondary caused by prior surgery. In this study, we discuss clinical manifestation acquired nasopharyngeal investigate if there relation grade severity obstructive sleep apnea (OSA) patients’ symptoms. So, cross-sectional study was conducted on patients who had post-surgical different grades. Then, snoring ± OSA VAS symptoms in those assessed grades NPS, results were also statistically compared. Results Within included 22 patients, no statistical differences 1 2 regards age ( p = 0.0619) sex 0.21137). The mean AHI significantly more 0.004) than NPS. difficult nasal breathing dysphagia worse < 0.0001) 1, while did not differ 0.3466) Conclusion Grade leads severe AHI, dysphagia, But difference cause intensity.
