Fenghua United Clinic wishes everyone a Merry Christmas 2024!

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 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. After orthognathic surgery to move the mandibular forward, not only did the AHI index drop from moderate to severe to 3.7, the respiratory tract was also significantly improved, the quality of sleep was improved, and the overall mental state was completely renewed. The surgery also improved the appearance of the retracted chin and allowed the patient to regain a healthy quality of life. It was a successful sleep apnea treatment case.

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.

A sleep apnea patient had to sleep in a separate room with his girlfriend due to severe snoring. After undergoing 3D customized orthognathic surgery and chin advancement surgery, I was most happy when I returned for a follow-up visit six months after the operation. The happiest thing was that my snoring had improved, my girlfriend no longer complained, and I could finally sleep in separate rooms. This case not only improved the patient's sleep quality, but also restored the couple's relationship, demonstrating the importance of sleep apnea treatment in improving the quality of life.

A 29-year-old male patient was troubled by severe sleep apnea (AHI=39.6) and was unable to adapt to positive pressure respirator treatment. Through 3D customized orthognathic surgery, counterclockwise rotation technology is used to rotate the upper and lower jaw bones forward and perform bilateral turbinoplasty. The postoperative results were significant: AHI dropped to 4.7 (improved by 88.13%), minimum blood oxygenation increased from 79% to 94%, and respiratory tract volume increased by 76.6%. This case demonstrates the effectiveness of orthognathic surgery in the treatment of sleep apnea.

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.
