Aim of this study was to evaluate the effects of a non-invasive external nasal dilator
(Breathe Right) in a selected sample of habitual snorers without OSA. Twenty subjects
have been evaluated before and after 8-night treatment by means of a portable multi-channel
monitoring device (MESAM 4). Snoring percentage (a visual scoring of each 5-
min epoch was performed) resulted lower in the “treatment nights” in comparison to
baseline (25.7% vs 32.9%), but the difference was not statistically significant (p<.06). Se-ven
subjects were arbitrarily defined as “responders” since they had a reduction > 10%
of the snoring percentage in the “treatment nights”. No difference was found in the
clinical, ENT, cephalometric characteristics between “responders” and “non-responders”.
Snoring percentage variation with the nasal dilator was significantly correlated with the
subjective improvement of sleep quality (p=.02). (Sleep and Hypnosis 1999;1:173-176)
