( y-five consecutive adults with history ...)Palatal Implant Procedure Proven Effective in Eliminating Snoring,Health

y-five consecutive adults with history of snoring, daytime sleepiness, with mild to moderate OSAHS were enrolled. Quality of life (QOL) surveys, measures of snoring intensity, and Epworth Sleepiness Scale (ESS) were obtained. Patients were randomized to receive treatment either with three palatal implants or with a sham procedure without implants. Both physician and patient were blinded with respect to the randomization. At three months, polysomnography was repeated, and the subjects were reassessed with the above mentioned surveys. Objective and subjective results were then compared for the experimental and control groups.

Results:

Fifty-five patients completed the study (29 experimental and 26 control). AHI improvement was statistically significant for the experimental group. Objective cure was defined as 50 percent reduction in AHI and AHI < 20. Objective cure was statistically higher in the experimental group (37.9 percent vs. zero percent). In general, QOL scores showed greater improvement in the experimental group as compared with the control group. Subjective improvement in snoring (defined as at least a 50 percent decrease), was significantly higher in the experimental group than in the control group (62.1 percent vs. zero percent). Daytime sleepiness was significantly decreased in the experimental group and remained statistically unchanged in the control group.

Conclusions:

This study presents randomized, placebo-controlled evidence on the effectiveness of palatal implant for improvement of AHI, QOL, snoring intensity, and daytime sleepiness. Patients treated with palatal implants demonstrate a significant improvement in objective and subjective measures when compared to a sham surgical control group in OSAHS. This study provides level 1 evidence that the palatal implant procedure can result in a significant decrease in AHI and that it has a 37.9 percent cure rate of mild and moderate OSAHS that compares favorably
