From his computed tomography before surgery, it was shown that he belonged to type 2 bones. (That is, a receding jaw and no chin) This is a typical face shape for people with sleep apnea.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A retracted chin compresses the airway space, causing the airway to become narrow. After airway lift (orthognathic surgery), his AHI index was significantly reduced from 84.5 to 5.6, and the minimum blood oxygen concentration was significantly increased from 50% to 90%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the current literature, successful treatment is defined as a reduction in the AHI index below 10 or a 50% reduction in the AHI index before and after surgery.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.mch-osa.com\/wp-content\/uploads\/2024\/11\/AD_4nXdvgjIKJIGrSTavMz1IX_6cEss5sVAOL1mdUhyakthT-2yiuTrRlztyKj-DI3Kg2tnGxdov7BNc3GfNCy25cdPI5Ae4F9ShKb2upJ0A4xsHMDsIIOq_0kik4vX0ErUlHhI17AIatp2HZy7lhhgrdAAvJtC9keyD0m6hOdvntX0sl9D7dItkbM9.jpg\" alt=\"Sleep monitoring reports comparing pre- and post-operative results showed that the AHI decreased from 84.5 and the lowest blood oxygen saturation increased from 501 TP3T to 901 TP3T.\" title=\"\"><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">As we can see from the photos, the orthognathic surgery significantly widened his airway and also improved his appearance, making his jaw more proportional.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We are so happy that he can now breathe easier, sleep better, and face a better life.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.mch-osa.com\/wp-content\/uploads\/2024\/11\/AD_4nXfx0n9Qjld2xp1GRI583SgXpgZyJYe2Qt5eWQoxcvmqrJgTDrgyItcG9jVe-250nUOhCfvur3rcr16sfpuI0woqkZQ8Bai2pxwsNBXBERewJjZT_acUgmfdKNG5K8haEOjGpIj4wzGtZdIn8v-FL9QyuDnakeyD0m6hOdvntX0sl9D7dItkbM9.jpg\" alt=\"Comparison of the facial airway before and after orthognathic surgery; postoperative airway widening.\" title=\"\"><\/figure>\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_4nXcbBI8zH3of3buOcP8H76cFg_-mL4i9lbY_Lnr9nG-931gBeIqd1rVYMcdYaW7immgFE9L8yjayQq2YaSYIQEBoHOaZpN_ayY1qSlNIeec9DkPfg8plqGT3OLBFi2QUAmSlTUFiItzuMXCfVxvjdfsv1-5keyD0m6hOdvntX0sl9D7dItkbM9.jpg\" alt=\"Frontal appearance comparison before and after orthognathic surgery for patients with mandibular retrusion\" 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_4nXdViIHXOpLRcPVq4cPFvAScNEyWsSAadypCoBbLIPOCmDCSbuwJuZqp2HvDY9I7rKD8luc6xRSarXyruMCIWzTGegRUWxt8pAgkpgfZXId5Pi1Dh-TZJxHHbrarD-kKx_8_fGe3OzsDY5pq1t94WfkGVc95keyD0m6hOdvntX0sl9D7dItkbM9.jpg\" alt=\"Comparison of 45-degree bevel appearance 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_4nXen9E2DXS-v1hWYTniitwDTK9vu-9GzkYaI_O2B4OVJ4oc2df0lBxOR__GOO8fZLbfLXp81I4a11saUuzeCe0FDPj9LSZxuUDYF4P8QJ8q8rglGG2IQ2lbrjEdJOJGSUP-iA8_9YY-nN7FkCcV4ccQaHJ3SkeyD0m6hOdvntX0sl9D7dItkbM9.jpg\" alt=\"Comparison of chin and jaw 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_4nXcA7ezvvAZJw4xLaPZB2Eax4YG5PvbyJt68d-MiW6-q0iB9Mya6pWWpHjHt_wjZfAWmAPfseR-8YsjXE-4Z0lH1om7xFoDJj_DXfRLaIHzOVLfYx_t0F7a_0M1RAv3A90XZ1kXjVkmKav-bmvAQP-9NN6wNkeyD0m6hOdvntX0sl9D7dItkbM9.jpg\" alt=\"Comparison of side-view photos before and after 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_4nXdUcfhoaQnoSDpPTfVovxL8om7lNZQhvGWZB_ELXr6e2jMcJjmvPtgZg33Bz5iutSjI6re8qPmxhC8P0r7Yy72uIDRm5uWwp8iSMMfxV7_waBBhu4h19ImiMYHApjIcW-zhcYgPbeXJXwlfUbyy4otl6UAdkeyD0m6hOdvntX0sl9D7dItkbM9.jpg\" alt=\"3D computed tomography before and after orthognathic surgery showed a significant increase in airway space postoperatively.\" title=\"\"><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Recovery progress<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><img fetchpriority=\"high\" decoding=\"async\" alt=\"A record of facial recovery from day 1 to day 30 after orthognathic surgery.\" src=\"https:\/\/www.mch-osa.com\/wp-content\/uploads\/2024\/11\/AD_4nXdd7kU9ZNfqBk5YVqtSsYDjh-7ZrrW3ejQvOciSixFUaSwIsWVLZDnWxxHGo541zL8Y88INMxOAA5364-HU-CvJt4HwATm1OW0s56orhWZ6tJJTbdgss0oNN7bUkMs1dFxQuVBDsvj0t4v4mQyWn-3tEkPukeyD0m6hOdvntX0sl9D7dItkbM9.jpg\" width=\"361\" height=\"360\" title=\"\"><\/h3>","protected":false},"excerpt":{"rendered":"<p>Discuss the treatment case of a patient with severe sleep apnea.
