Rapid maxillary expansion treatment is commonly used treatment for correcting such deficiencies and has been found to be effective in improving respiration and sleep architecture in children with obstructive sleep apnoea (<jats:styled-content style=\"fixed-case\">OSA<\/jats:styled-content>). However, thus far, the effect of surgically assisted rapid maxillary expansion (SARME) treatment on sleep architecture and breathing of normal subjects has not been assessed. We hypothesised that sleep quality will improve after maxillary expansion treatment. The objective of this study is to access the effect of maxillary expansion treatment on sleep structure and respiratory functions in healthy young adults with severe <jats:styled-content style=\"fixed-case\">MTD<\/jats:styled-content>. This is a prospective and exploratory clinical study. Twenty\u2010eight consecutive young adult patients (15 males and 13 females, mean age 20\u00b76\u00a0\u00b1\u00a05\u00b78\u00a0years) presenting with severe <jats:styled-content style=\"fixed-case\">MTD<\/jats:styled-content> at the orthodontic examination were recruited into the study. All the participants underwent a standardised <jats:styled-content style=\"fixed-case\">SARME<\/jats:styled-content> procedure (mean expansion 6\u00b75\u00a0\u00b1\u00a01\u00b78 and 8\u00b72\u00a0\u00b1\u00a01\u00b78\u00a0mm, intercanine and intermolar distance, respectively) to correct malocclusion caused by <jats:styled-content style=\"fixed-case\">MTD<\/jats:styled-content>. An overnight in\u2010laboratory polysomnography, before and after the treatment, was performed. The mean follow\u2010up time was 9\u00a0months. The main outcome parameters were the changes in sleep architecture, including sleep stages, arousals, slow\u2010wave activity (<jats:styled-content style=\"fixed-case\">SWA<\/jats:styled-content>) and respiratory variables. Before surgery, young adult patients with <jats:styled-content style=\"fixed-case\">MTD<\/jats:styled-content> presented no evidence of sleep breathing problems. At baseline sleep recording, 7 of 28 (25%) had apnoea\u2010hypopnoea index (<jats:styled-content style=\"fixed-case\">AHI<\/jats:styled-content>)\u00a0\u2265\u00a05 events per hour. No negative effect of the <jats:styled-content style=\"fixed-case\">SARME<\/jats:styled-content> was observed in questionnaires or sleep laboratory parameters. In the patients with a higher baseline <jats:styled-content style=\"fixed-case\">AHI<\/jats:styled-content> (<jats:styled-content style=\"fixed-case\">AHI<\/jats:styled-content>\u00a0\u2265\u00a05\u00a0h of sleep), we observed a reduction in <jats:styled-content style=\"fixed-case\">AHI<\/jats:styled-content> after surgical treatment (<jats:italic>P\u00a0<\/jats:italic>=<jats:italic>\u00a0<\/jats:italic>0\u00b7028). <jats:styled-content style=\"fixed-case\">SARME<\/jats:styled-content> did not have a negative effect on any sleep or respiration parameters in healthy young individuals with <jats:styled-content style=\"fixed-case\">MTD<\/jats:styled-content>.
