30 patients with mild sleep apnea were enrolled in a study to evaluate the use of an adhesive patch (mouth tape) who were breathing through the mouth during sleep.
The Epworth Sleep Scale reduced from 8.1 to 5.2 while wearing the tape, and visual analog scale of snoring reduced from 7.5 to 2.4.
Snoring intensity reduced from 49.1 to 41.1, and median snoring index reduced from 146.7 to 40 per hour while wearing the adhesive porous patch.
Furthermore, the apnea hypopnea index reduced from 12 per hour to 7.8 per hour.
The researchers concluded that the wearing of a porous oral patch is a useful device to help patients with mild sleep apnea and habitual oral mouth breathing.
