Purpose The aim of this randomized clinical trial was to evaluate the effects of tooth tissue-borne (TTB), tooth-borne (TB), and bone-borne (BB) rapid maxillary expansion appliances on obstructive sleep apnea (OSA) severity. Trial design Three-arm parallel randomized controlled trial. Methods This study was designed in parallel with an allocation ratio of 1:1:1. Forty six patients with narrow maxilla and diagnosis of OSA recruited from the Department of Orthodontics, ### University were randomly assigned to three groups according to appliance used: tooth tissue-borne, tooth-borne and bone-borne expanders. The primary outcome of this study included polygraphic change in sleep parameters. Secondary outcome was the correction of posterior crossbite. Each subject underwent overnight sleep test with polygraphy at baseline and 3 month-follow-up of treatment. Randomization was performed using a computer-generated randomization program The outcome assessor was blinded to group assignment. For the statistical analysis, Kruskal-Wallis analysis and Dunn-Bonferroni tests were used for inter-group comparisons and Wilcoxon analysis was used for intra-group evalaution. p<0.05 was accepted statistically significant. Results The amount of expansion in maxillary width and upper intermolar width were similar in all goups (95% confidence interval [CI], p>0.05). The groups were similar in terms of apnea-hypopnea index (AHI) and oxygen saturation parameters at baseline (95% [CI], p>0.05). After 3 months of treatment, there was no significant decrease in AHI and oxygen desaturation index, and no increase in minimum and mean oxygen saturations (95% [CI], p>0.05). Supine AHI values were decreased by the tooth tissue-borne and tooth-borne appliances, but these changes were not significant (95% [CI], p>0.05). Harms No serious harm ocurred except mild gingivitis. Conclusions Similar skeletal and dental expansion of maxilla were observed after RME with all expanders. Although the decrease in AHI was not significant, RME can be used as an adjunct to the primary treatment in OSA patients.

Abstract Introduction Residual pediatric Obstructive Sleep Apnea (OSA) after gold-standard treatment with adenotonsillectomy occurs in nearly 20% of the patients. Treatment alternatives are scarce and based upon low-level evidence. Rapid maxillary expansion is an orthodontic-orthopaedic treatment of maxillary transverse hypoplasia that has shown promising results in pediatric OSA based upon nasal and oral cavity enlargement. Revision adenoidectomy of all-purpose adenotonsillectomies in population-based studies is 4,9%, and a three-fold risk in OSA patients has been reported. We present data from an ongoing randomized clinical trial (ERMES) highlighting the importance of nasofibroscopic control of the adenoid tissue in residual pediatric OSA patients. Methods According to the study protocol of our ongoing randomized clinical trial (Rapid maxillary expansion for treatment of residual pediatric obstructive sleep apnea; Acronym: ERMES; NCT02947464) patients aged 4 to 9 years old with polysomnographic evidence of OSA persistence after adenotonsillectomy were randomized to either rapid maxillary expansion or wahtchful waiting. They underwent fiberoptic nasopharingoscopy in order to stablish the amount of adenoidal tissue present at the time of inclusion and at polysomnographic control twelve months later. The nasopharyngeal occupation was measured in a 1 to 4 scale. Patients that graded 3 or 4 at the initial nasofibroscopy were excluded from the study due to their surgical revision indication; if they developed grade 3 or 4 adenoid hypertrophy and persistence of symptoms at the final assesment they were offered re-adenoidectomy. Results A total of 5 patients developed an adenoid regrowth amenable for revision surgery: 4 of them within the rapid maxillary expansion group and one in the watchful waiting group. All of them had experienced either worsening or very mild improvement in their apnea hypopnea index (AHI). Conclusion Adenoid regrowth is a known risk factor for pediatric OSA persistence. The anatomical enlargement of the nasal and oral cavity provided by means of rapid maxillary expansion may trigger such overgrowth in otherwise predisposed residual OSA patients. Fiberoptic nasopharyngoscopy is therefore mandatory in the follow-up of such complex cases, since adenoid regrowth may hinder resolution of OSA and its associated symptoms. Support (if any) ERMES Randomized Clincal Trial (NCT02947464) is funded by Departamento de Salud del Gobierno Vasco.
