Abstract
Under a hypothesis that the intranasal steam inhalation before sleep would be effective for the decrease of snoring supressing vagotonia, Katori et al reported a demonstration based on a subjective assessment using questionnaires of bedside observers in 1992.
However, decrease of sonoring by the steam inhalation has not been confirmed by a strict objective assessment.
In the preliminary study patients with snoring underwent 6 days of baseline observation and 6 days of treatment with hyperthermic aerosols using EW 635 for 10 minutes before sleep. The effect of treatment was assessed by decrease of snoring by each bedside observer.
underwent 2 days of baseline observation and 2 days of treatment with the same hyperthermic aerosols for 10 and 5 minutes respectively before sleep. The effect of the treatment was assessed by decrease of snoring by 5 hours' recording and its analysis using a measuring amplifier with a personal computer and a thermograph.
In both models there was significant difference in the degree of snore, showing its decrease by this aerosol therapy. The main study also revealed that the decrease was much greater in 10 minutes treatment than 5 minutes one.
Mechanisms of the decrease in snoring under this therapy have not all be elucidated, however, it was concluded by this study that this would be the first choice therapy for snore patients before performing “snore operation”.
