Abstract
Objective: Many obstructive sleep apnea(OSA)patients have nasal obstruction. Further, most patients discontinue wearing an oral appliance(OA)for improving respiration due to nasal obstruction. We aimed to develop a nasal breathing stimulator(NBS)for use in combination with an OA to promote nasal breathing. Methods: Thirteen OSA patients wore a NBS, Max-Air Nose Corns ® , Mute with hole ® , which expands the nasal cavity from the inside, and Breathe Right ® , which expands the nasal cavity from the outside, and compared the resultant changes in respiratory measures with those when a device was not used. The inspiratory flow rate(peak nasal inspiratory flow: PNIF)and visual analogue scale(VAS)scores were measured under five conditions. Furthermore, PNIF was measured under four conditions: OA(-)NBS(-), OA(+)NBS(-), OA(-)NBS(+), and OA(+)NBS(+), and a sleep test was performed. Results: PNIF was significantly higher when wearing an NBS compared with the other four devices(p < 0.001). In addition, PNIF was significantly higher in OA(+)NBS(+) than that in the other three conditions(p < 0.001), and OA(+)NBS(+)improved the respiratory disturbance index(p < 0.001), lowest SpO 2( p < 0.001), and Epworth sleepiness scale(ESS)score(p < 0.001)on the sleep test. Discussion: Wearing the NBS improved breathing in patients who did not benefit from OA treatment alone and in those who discontinued OA use due to nasal obstruction.
