Abstract
Background
Obstructive sleep apnea (OSA) is a condition characterized by 20-40 second episodes of breathing cessation during sleep. The hard palate serves as both the roof of the oral cavity and the floor of the nasal cavity. Constriction of the palate can have profound effects on the passage of oxygen into the lungs. Polysomnography is the gold standard test for detection of the presence and severity of obstructive sleep apnea. Recently, a home sleep testing device known as the WatchPAT has been implemented as an adjunctive test. This randomized controlled crossover trial will investigate the role of maxillary expansion in children at risk for OSA using the WatchPAT as the diagnostic tool.
Methods
Twelve patients aged 12-16 without any medical syndromes were randomly assigned to either treatment or observation group. Pre-treatment (T1) records were taken on all patients. Treatment group was fitted with bonded type, rapid maxillary expanders and treated for three months according to an expansion protocol utilized by the private practice of GKG Orthodontics. A second WatchPAT study was performed at the completion of the three month period (T2). The treatment group was followed an additional three months without further expansion and a final T3 WatchPAT study was performed. The control group had a T1 WatchPAT study followed by three months of observation without expansion. A T2 study was performed at the end waiting period and then an expander was placed. The methodology then mirrored that of the treatment group.
Results
Pre treatment AHI was found to be 2.47 episodes per hour for the treatment group. Post-treatment AHI was found to be 2.10 episodes per hour. Pre-treatment snoring frequency was measured at 2.57 percent of the night before expansion therapy and 1.60 percent after treatment.
Conclusions
AHI and snoring as measured by WatchPAT, decreased following expansion. Initial analysis of this pilot study shows a positive effect of rapid maxillary expansion on sleep quality as measured by AHI and other parameters.
