This case shares the treatment experience of a patient with moderate sleep apnea (AHI 22.9). The patient had sleep problems due to mandibular and chin retraction, and was unable to adapt to CPAP treatment. Through 3D customized orthognathic surgery, using the treatment method of counterclockwise rotation and forward movement of the upper and lower jaw bones (CCW-MMA), the 6-month follow-up showed that the AHI dropped to 2.7, successfully improving the symptoms of sleep apnea, while improving the Appearance, the patient was quite satisfied with the surgical results.

A young man was troubled by severe obstructive sleep apnea (OSA), with an AHI index as high as 55.8, and symptoms such as loud snoring, daytime sleepiness, headaches, and difficulty concentrating. Because he was unwilling to use a positive-pressure respirator, he underwent mandibular advancement surgery (MMA) combined with chin advancement surgery to successfully expand the airway space. The AHI dropped to 3.9 6 months after the operation, and his symptoms were significantly improved. This case demonstrates the therapeutic effect of MMA surgery on patients with severe OSA, providing patients with a treatment option that does not require respirators.

Discuss the treatment case of a patient with severe sleep apnea. The patient's AHI index is as high as 84.5, and he has a typical face with a receding mandible. After airway lifting treatment through orthognathic surgery, the AHI index was significantly reduced to 5.6, and the minimum blood oxygen concentration was increased from 50% to 90%. The surgery not only effectively improves the airway space, but also makes the patient's jaw proportions more harmonious. The case details the surgical plan, postoperative changes and recovery progress, providing treatment reference for patients with similar problems.

Let me share the case of a 39-year-old male patient. Due to insufficient development of the upper and lower jaw bones, they were compressed backwards, resulting in airway stenosis, sleep apnea (AHI 22.5), and daytime sleepiness. The patient's airway space was successfully improved through orthognathic surgery on both jaws, nasal septum correction and lower nose clip plasty surgery. Three months after the operation, the AHI dropped to 5.1, the lowest blood oxygen concentration increased to 93%, and the patient's mental state and quality of life were significantly improved.

A 28-year-old man sought treatment for severe sleep apnea. The preoperative AHI index was 45 and the lowest blood oxygen concentration was 76%. After diagnosis, it was found that the upper and lower jaw bones were underdeveloped, resulting in airway compression. Through 3D customized orthognathic surgery, counterclockwise rotation and forward movement of both jaws were performed. After the operation, the AHI index dropped significantly to 0.4, and the lowest blood oxygen concentration increased to 92%. The patient's symptoms such as snoring, light sleep and daytime sleepiness have been significantly improved, the respiratory space has been effectively improved, and the treatment effect is excellent.

Discuss the case of sleep apnea treatment in a female patient with long chin. Unlike other patients with mandibular retrusion, her airway obstruction point was located in the retropalatal space and nasal cavity. It was diagnosed that it was caused by maxillary retrusion and stenosis. Through clockwise rotation of both jaws, orthognathic surgery moves the upper jaw forward and simultaneously reduces the thickness of the inferior turbinate, successfully improving respiratory problems. This case shows that sleep apnea has multiple causes and requires accurate diagnosis and customized treatment plans.
