A significant number of the patients, 62 per cent, were demonstrated to have significant improvement in the short term. Single dose injection snoreplasty seems not only to be an effective investigation but may constitute a safe and simple treatment within the clinic. At the very least, patients in whom the palate appears not to be the problem are prevented from undergoing painful, unpleasant surgery. Our results support the use of injection snoreplasty, both as an investigation and in some patients as a treatment, for habitual snoring.
