Sleep apnea hypoventilation syndrome, referred to as snoring, is associated with multiplanar obstruction or narrowing of the upper airway and/or central regulatory dysfunction, and the diagnosis requires polysomnography (PSG) to help assess the condition. Treatment is divided into two main categories: 1) surgical expansion of the narrowing planes such as nasal and soft palate pharyngoplasty, combined with tongue root and mandibular orthopedics or even tracheotomy if necessary; 2) wearing a CPAP during sleep, and other lifestyle modifications such as weight loss and smoking and alcohol cessation can also play a supporting role. It is worth noting that unless the condition is simple, it is often not easy to improve the condition comprehensively with only a single plane of local surgery. If you cannot adapt or if nasal ventilation affects the function of CPAP, consider nasal dilation surgery or even tonsillectomy and palatopharyngoplasty, and then consider whether it is still necessary to wear CPAP if appropriate.
