Surgery is considered only if the patient is not suitable for wearing a whistler Surgery is not the first treatment option, and surgery is considered only if the patient is not suitable for wearing a whistler. If the patient is very young, has no contraindications to surgery, has no complications due to prolonged sleep apnea, and is evaluated by the surgeon to be curable after surgery, such a patient can be operated on. If some seriously ill patients, the doctor assesses that the condition can only improve after surgery, he is advised to try wearing a whistler first and only do surgery if he cannot receive a whistler. What conditions are met to do surgery 1. Patients with enlarged tonsils visible when they open their mouths, and patients with significant anatomical narrowing of the airway cross-section found by endoscopy. 2. Whether surgery can be done depends on monitoring the severity of the whistling pause: this includes the minimum oxygen saturation, the duration and frequency of the whistling pause, and then a comprehensive assessment. In general, the lighter the patient, the more suitable for surgery. Because there are limits to the changes surgical procedures can make to the airway, if a patient’s apnea has become so severe that surgery cannot completely eliminate it, for example, if it can only be eliminated in the lateral position but not in the supine position; if it can only be eliminated in light sleep but not in deep sleep when the muscles are more relaxed, only partial results will be obtained in this group of patients. The patient’s request for subjective symptom change is also important. Each person has a different tolerance level for whistling pauses, and some people will wake up with even one whistling pause all night. If the patient requires that all whistling pauses must be completely eliminated, the procedure needs to be evaluated to see if it can be done. The degree of modifiability of the airway and the severity of the condition should be considered together. 3. It will not cause surgical complications. Surgical procedures should consider whether the anatomical structure can assume the necessary functions of the body, and consider whether the bone structure can heal again, etc. Low oxygen saturation Wear a whistler for six months before surgery Such patients generally have a longer period of whistling pause. If the oxygen saturation is so low that the patient can be awakened, it means that his central regulation is poor. Surgery cannot treat the central problem. Although the postoperative airway is open, the center cannot command the diaphragm and intercostal muscles to move, and the patient still cannot gasp for air. This both affects the surgical outcome and poses a risk to the surgery. Such patients need to wear a whistler for a period of time first, usually three months to six months, preferably six months, to have surgery.
