Article Synopsis
- The study explores the relationship between nasal resistance, measured by 4-phase rhinomanometry, and the frequency of apneas vs. hypopneas in obstructive sleep apnea (OSA) patients.
- One hundred thirty-nine male OSA patients underwent both acoustic rhinometry and rhinomanometry tests to assess these relationships and other respiratory indices.
- Results indicated that patients with a higher hypopnea-to-apnea ratio were significantly more likely to have increased nasal resistance, but no strong ties were found between acoustic measurements and the respiratory indices typically assessed in OSA.
Background: This study aims to investigate how increased nasal resistance affects respiratory variables in obstructive sleep apnea (OSA). In this setting, to assess how nasal resistance, as measured by 4-phase rhinomanometry, affects the distribution of hypopneas and apneas when measured with routine Sleep Polygraphy (PG).
Methods: PG recordings were analysed and 4-phase rhinomanometry was conducted.
The aim of this study was to explore the usefulness of unilateral, combined unilateral (left + right), and bilateral peak nasal inspiratory flow (PNIF) measurements in assessing the results of nasal septal surgery. Nasal obstruction was recorded subjectively and objectively before and 4 months after nasal septoplasty using a visual analogue scale (VAS) and a PNIF meter. Nasal septoplasty (58 patients) and septoplasty with turbinoplasty (68 patients) were performed on 126 patients (85 males; 41 females) with a mean age of 32.
