Treatment of the Obstructive Sleep Apnea Syndrome Using A Nasopharyngeal Tube

Nasopharyngeal airway stenting devices for obstructive sleep apnoea: A systematic review and meta-analysis

“…According to Nahmias and Karetzky, some patients have chosen to use nasal trumpets for these purposes; however, local trauma and consistency of usage findings are not reported. 30 There are limitations to this study. First, despite our best attempts to identify all articles, without regard to language, it is possible there are additional studies that meet our inclusion and exclusion criteria, which were not identified during this review.…”

“…In 1981, Afzelius and colleagues described two patients with severe OSA (40.8 and 51.3 apnoeas per hour per night, respectively) and excessive hypersomnia. 15 There was complete cessation of OSA in these patients after the insertion of size [30][31][32] French nasal trumpets, with polysomnography demonstrating no apnoeas; in addition, there was resolution of the patients' hypersomnia.…”

“…This revealed improvements in: apnoea index, from 40.1 to 14.8 episodes per hour ( p < 0.0001); AHI, from 54.8 to 32.2 episodes per hour ( p < 0.001); and lowest oxygen saturation level, from 68.7 per cent to 77.1 per cent ( p < 0.005). 30 Thirteen of the 16 patients (81 per cent) were able to use the nasal trumpet long term, with good compliance (patients were followed up for at least 4 months). 30 Another study, by Afzelius et al, in which two patients were evaluated, demonstrated a reduction in apnoea index, from 46 to 0 episodes per hour.…”

“…29 Nahmias and Karetzky evaluated 44 OSA patients (mean age, 53 years); these patients had used a nasal trumpet at home for between 1 and 5 weeks. 30 Of the 44 patients, only 24 were able to tolerate the therapy, and 16 agreed to undergo subsequent polysomnography. This revealed improvements in: apnoea index, from 40.1 to 14.8 episodes per hour ( p < 0.0001); AHI, from 54.8 to 32.2 episodes per hour ( p < 0.001); and lowest oxygen saturation level, from 68.7 per cent to 77.1 per cent ( p < 0.005).…”

Pilot Study of a Nasal Airway Stent for the Treatment on Obstructive Sleep Apnea

“…Some previous studies have reported oral or nasopharyngeal appliances as non-surgical alternatives to CPAP for OSA patients who do not tolerate CPAP treatment [12][13][14][15][16][17][18]. Although the concept of nasopharyngeal tube insertion to maintain airflow through the upper airway during sleep was proposed in the 1980s and has been reviewed before [7,12,18], such devices are not currently in common use. The nasal trumpet has been used successfully to decrease airway obstruction in the short term, such as immediately after surgery for OSA [18].…”
