Abstract
- Objective: To investigate whether rapid maxillary expansion (RME) is a useful treatment method for nocturnal enuresis (NE) and whether the treatment effect is due to placebo. The study also aimed to identify prognostic variables in patients responding to treatment.<br />Materials and Methods: Thirty-eight children with therapy-resistant NE were recruited and randomized into two groups: the intervention group or placebo group. Both groups were treated with RME, but the placebo group received treatment with a sham appliance for 2 weeks before having the actual treatment. A medical history focused on micturition habits, previous treatment, heredity, and sleep disorders was taken. Daytime voided volumes and nocturnal urine production during wet nights were recorded before the intervention.<br />Results: Of the 38 patients recruited, two dropped out as one patient was unable to take dental impressions and one refused to have the appliance fitted. There was a statistically significant reduction of wet nights after the RME treatment ( P < .001). No significant reduction was found after the placebo treatment ( P < .40). Eleven patients (35%) had their enuresis frequency reduced by >50%. Large voiding volume and a wide maxilla at baseline had a strong association with positive treatment outcome.<br />Conclusions: RME has a modest effect on children with therapy-resistant NE. The treatment outcome does not seem to be due to a placebo effect of the appliance. A wide maxillary width and large voiding volume at baseline seem to be positive predictors regarding response to treatment.
