Computed tomography (CT) imaging demonstrated a markedly narrowed posterior airway space, primarily due to underdeveloped maxillary and mandibular growth. The retruded maxilla, combined with airway collapse, allowed the relaxed uvula to vibrate within the constricted space, producing loud snoring. The retrognathic mandible further contributed to posterior tongue displacement, reduced tongue muscle tone, and a low-positioned hyoid bone\u2014key anatomical factors in the pathogenesis of OSA.<\/p>\n\n\n\n

To address these structural and functional issues, we planned a counter-clockwise rotation maxillomandibular advancement (CCWR-MMA) procedure. This surgical approach included:<\/p>\n\n\n\n

    \n
  1. Maxillary advancement<\/strong>, which tightened the soft palate musculature and repositioned the uvula anteriorly, away from the posterior pharyngeal wall, thereby reducing snoring;<\/li>\n\n\n\n
  2. Mandibular advancement<\/strong>, which, through its anatomical connection to the tongue base, repositioned the tongue anteriorly, minimizing posterior collapse;<\/li>\n\n\n\n
  3. Additionally, the hyoid bone<\/strong> was drawn forward and upward, distancing it from the posterior airway wall and significantly expanding the pharyngeal space to improve airflow.<\/li>\n<\/ol>\n\n\n\n

    Pre- and postoperative CT scans clearly demonstrated how skeletal repositioning led to soft tissue tensioning and airway enlargement. Postoperatively, the patient's AHI decreased from 17.3 to 6.3, and minimum oxygen saturation improved from 83% to 89%. Clinically, the patient reported markedly improved sleep quality and daytime alertness, with a refreshed and energized demeanor.<\/p>\n\n\n\n
