Breathe right nasal strips and the respiratory disturbance index in sleep related breathing disorders

This investigation assesses the effects of Breathe Right nasal strips on th e respiratory disturbance index (RDI) measured by polysomnography in patien ts suffering from obstructive sleep apnea and snaring. The positive effect of these strips on nasal ventilation was shown in earlier studies. Twenty-s ix patients with art RDI higher than 10 in an initial measurement underwent a second preoperative polysomnography with Breathe Right nasal strips in p lace. Nineteen of these 26 patients showed reduction of RDI during the seco nd night of polysomnography using the nasal strips, indicating that nasal o bstruction seems to be a predominant factor in the etiology of snoring and apnea in these individuals. Demographic data, medical history, rhinoscopy, clinical assessment of pharyngeal obstruction (Mueller's maneuver), as well as anterior rhinomanometry and acoustic rhinometry were used to identify t ypical findings correlating with a positive effect of the Breathe Right nas al strips on the RDI: 1. Hyperplasia or hypertrophy of the lower turbinates , septal deviation, and/or allergic rhinitis. 2. None or only minor pharyng eal obstruction. 3. Age less than 55 years. if a positive effect is seen du ring polysomnography with the strips in place, patients will most likely pr ofit from an improvement of nasal ventilation. This may help to target more effectively septal or turbinate surgery if applicable. In other cases, ifa significant RDI reduction is obtained by the use of the nasal strips, they could also offer a noninvasive modality of treatment, especially since the high degree of co-morbidity in this group of patients can sometimes make a surgical approach less favorable.
