By moving the mandible forward, the airway can be greatly widened, replacing the passive opening of the airway by a positive pressure respirator.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The case introduced today is a patient with moderate to severe sleep apnea. Although his AHI index is not as high as that of a person with severe sleep apnea, sleep apnea has a great impact on his life.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to the sleepiness scale he filled out before surgery, he scored 20 points. Almost in static situations, he will fall into a very sleepy physiological state. He would feel so tired during the day that he could barely stay awake at work, and he would even need to take a nap in the afternoon to continue working.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After orthognathic surgery at our clinic, his AHI index dropped to 3.7. He said that after the operation, his sleep and breathing returned to normal, he felt more energetic every morning, and his body had a real rest. We can see from the photos that not only his airway was greatly widened, but his chin-retracted appearance was also improved.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Appearance changes<\/h2>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.mch-osa.com\/wp-content\/uploads\/2024\/11\/AD_4nXd7VPhKDjJ65kGASupF3wfqaGy4U8C_0tDcemhwWGzYuSGNAImqWGAuF0Lv85t3W00SxKISjv0-YkQ9qXoeYvUkTcBJhMdAmcomBuERHzZe181JrdJag5jJpXBMRDpMI0dowUbYz9x9VCzNNbzbhhR188CDkeydqgYrLhMonJujvJAlmtVINHx.jpg\" alt=\"Before and after jaw reduction surgery: chin contour comparison\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.mch-osa.com\/wp-content\/uploads\/2024\/11\/AD_4nXcPtGpQ4TMMZos0tvZ8lYtuBDkiikpYQdPblNlJSpmsDY4bUT6iYFJbeYFENlKvN1c_UunKNBj99weuHnWVsnoByQFiMeklXaUtXEz5OhlNnKICzUbXdjbL3aQEVMCex1rEnvoBm2DSRLLEfp9KFLReRnEkeydqgYrLhMonJujvJAlmtVINHx.jpg\" alt=\"Comparison of 45-degree bevel appearance before and after mandibular advancement surgery\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.mch-osa.com\/wp-content\/uploads\/2024\/11\/AD_4nXde9KYHPKHf35bv0QVlx-VIuKkoS7ecNKYP9mkNHAElKbZ0iXnVXCNZLubtJy3HBm4MUm6aonKxKvLh7kRwtvlHkfg5Jbz0DhQ1YbeZbJ9Q2-eSMwgoNRRaynxhP9gNuguivHn0YpdVBZBAOxWkitfocwTkkeydqgYrLhMonJujvJAlmtVINHx.jpg\" alt=\"Before and after frontal appearance comparison of mandibular advancement surgery\" title=\"\"><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Comparison of tomography before and after surgery<\/h2>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.mch-osa.com\/wp-content\/uploads\/2024\/11\/AD_4nXdqHExZ90Nu4hnVMOAVjA-3FKQC_ajK0j-_zh5jD7UkQCLAQxa1tRl9kUi-kIA8wEkC9b2sFZVarf3_9u1DUPGZbsHzPd9udRIexv-O7xAkCrVc8ajPLy31PaTOreyNJ-0_rcd5CykvpWgcjl8ovaXwcnQkeydqgYrLhMonJujvJAlmtVINHx.jpg\" alt=\"Comparison of CT scans and side profile contours before and after orthognathic surgery\" title=\"\"><\/figure>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.mch-osa.com\/wp-content\/uploads\/2024\/11\/AD_4nXdoRK7UPde7rDbXTHVZpywHzkEUSNWjdqhrv3aLGTdYc5NfOq_eJ2FMXshem6IblPPTN4qW3EDwD7MzKdza_yWQzQit98JFFPJpybq5FMwgkpX-efGM6ASOJXon6wDHYDfvTExN6fCUHFANotQqGBuofE8keydqgYrLhMonJujvJAlmtVINHx.jpg\" alt=\"Comparison of facial airways before and after jaw reduction surgery; postoperative airway widening.\" title=\"\"><\/figure>","protected":false},"excerpt":{"rendered":"<p>A patient with moderate to severe sleep apnea suffers from severe drowsiness during the day and difficulty staying awake at work due to narrowing of the airway due to retraction of the mandible.
