Diagnosis and treatment plan and postoperative changes

The patient was diagnosed with severe sleep apnea (AHI index as high as 84.5, and by definition an AHI index of ≥30 is considered severe sleep apnea). 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.

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%.

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.

As we can see from the photos, the orthognathic surgery significantly widened his airway and also improved his appearance, making his jaw more proportional.

We are so happy that he can now breathe easier, sleep better, and face a better life.

Warm reminder

Please follow the instructions of the doctor and nursing staff, take medicine regularly, pay attention to dietary taboos and keep the wound clean.
There may be complications such as bleeding, infection, inflammation, etc. after surgery. The degree will vary according to individual physical differences, so careful care is required. If the above situations occur, please contact us as soon as possible.
It is normal for 3 to 6 months after surgery to experience temporary slow sensation and unnatural expressions at the surgical site. Through independent massage and facial expression exercises, most patients will gradually improve within 6 to 12 months after surgery.
Anesthesia has certain risks, which are related to the patient's own physical condition. Patients must honestly and clearly report their health status and treatment history to the treating physician and anesthesiologist, and do not hide anything.
It is recommended to communicate with the doctor before surgery and clearly express treatment needs. However, the aesthetic appearance after surgery is subjective and should not be used as a basis for judgment of surgical results.
The results of surgery vary from person to person and need to be evaluated by a professional physician. Case pictures are publicly used with the authorization of the parties involved as auxiliary explanations of diagnosis and treatment, health education and medical knowledge sharing, and are for reference only.
