A non-randomized interventional pre-post study was conducted in 2018\u20132021 with up to 24-month follow-up at five US and Canadian sites. Participants were 55 enrolled OSA-diagnosed children, fit with a customized device worn in the evening and while sleeping to provide slow maxillary expansion. Participants were assessed for treatment efficacy by three co-primary endpoints, the Pediatric Sleep Questionnaire (PSQ), apnea-hypopnea index (AHI), and intermolar width; and two secondary endpoints, the PSQ Sleep-Related Breathing Disorders (SRBD) subscale scores and airway volume by cone-beam computed tomography (CBCT) scans. Forty-seven participants were included in the analytic dataset following trial completion after 12\u201324 months. PSQ symptom scores decreased 31.0% with a posttreatment-pretreatment difference score mean\u00b1SE and 95% CI of \u22120.13 \u00b1 0.019 [\u22120.17, \u22120.09]; AHI decreased 29.3% (\u22123.47\u00b11.015 [\u22125.52, \u22121.42]). All participants showed an intermolar width increase, averaging 13.0% (4.03 \u00b1 0.421 [3.18, 4.88]). PSQ SRBD subscale scores decreased 57.8% (\u22120.178 \u00b1 0.031 [\u22120.24, \u22120.12]). Airway volume by CBCT scans increased 67.8% (4053.78 \u00b1 885.433 mm\n                      <jats:sup>3<\/jats:sup>\n                      [2265.62, 5841.95]).

Seventy-nine percent of participants showed AHI improvement, with 61.7% improving by 50% or more, and 17% resolved their OSA. Seventy-seven percent with moderate or severe OSA improved by 50%, while 93% with severe OSA achieved this milestone. This is the first study demonstrating that slow maxillary expansion by this device is safe and efficacious in treating children with OSA.\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:italic>Trial registration<\/jats:italic>\n                      : ClinicalTrials.gov ID NCT05661747 (\n                      <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"https:\/\/clinicaltrials.gov\/ct2\/show\/NCT05661747\" ext-link-type=\"uri\">https:\/\/clinicaltrials.gov\/ct2\/show\/NCT05661747<\/jats:ext-link>\n                      ) Registered: December 14, 2022, retrospectively registered.\n                      <jats:table-wrap>\n                        <jats:table>\n                          <jats:tbody>\n                            <jats:tr>\n                              <jats:td colspan=\"2\">\n                                <jats:bold>What Is Known:<\/jats:bold>\n                                <jats:italic>\u2022 Adenotonsillectomy is the primary treatment for pediatric obstructive sleep apnea (OSA) but is invasive and has proximal and long-term risks.
