Abstract: This study (my PhD research) followed 329 children between ages of 7-9 yo, who were referred to me for an orthodontic consultation by their general dentist. The purpose of the study was to see what combination of treatments would most reduce the impact of sleep disordered breathing, in the paediatric population.
Based on the signs and symptoms of sleep disordered breathing problems, 326 patients had the standard orthodontic records of study casts, X-rays/CBCTs, extra oral and intra oral photographs, as well as a baseline sleep study (PSG). 305 sleep studies revealed mild to moderate sleep aponea. 21 patients PSG studies showed no OSA.
The patients were assigned to 1 of 4 treatment groups, plus a control group who did not receive any treatment (group 5): 1) ENT surgery only, or 2) ENT surgery and Myofunctional therapy, with a night time appliance (myobrace) (MFT) or 3) ENT surgery and orthopaedics/orthodontics, and 4) ENT surgery, orthopaedics/orthodontics, MFT and a night-time appliance (myobrace).
Sleep studies were performed for all patients, at baseline, and then after ENT intervention, after orthopaedic treatment, and finally after MFT. By comparing the results, the best outcome, for RDI reduction, was obtained when ENT surgery, myofunctional therapy and orthodontic therapy were used. Complete resolution of OSAs, in children, requires appropriate orthodontic treatment, such as maxillary development, maxillary protraction, and mandibular translation.
