Diagnosis and treatment plan and postoperative changes

The case shared today is a 39-year-old male patient who was referred by an orthopedist. He complained that he was always drowsy during the day, had constant nasal congestion, snored at night and had sleep apnea.

The sleep test found that his AHI index was 22.5 and the lowest blood oxygen concentration was 89%. He also tried positive pressure respirator treatment, but because it was so uncomfortable, he turned to surgery.

Computerized tomography showed that his upper and lower jaw bones were underdeveloped and compressed backwards, causing a narrowed airway. We designed a double-jaw orthognathic surgery for him, including Le Fort I osteotomy, bilateral sagittal split osteotomy, counterclockwise rotation of the occlusal plane, and forward lifting of his middle and lower facial bones.

In addition, during the same operation, the distorted nasal septum and the lower nose clips that were reduced on both sides were adjusted (the lower nose clips need to be molded, and the thickening of the lower nose clips may also cause respiratory obstruction).

Three months after the operation, a sleep test was performed again. His AHI dropped significantly to 5.1, and the lowest blood oxygen concentration increased to 93%. Patients also reported that their problems of daytime fatigue, nasal congestion and snoring were all solved.

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.
