Obstructive sleep apnea hypoventilation syndrome (OSAHS) is caused by the anatomical abnormalities of the upper airway, resulting in sleep apnea caused by repeated narrowing of the upper airway, resulting in hypoxemia (commonly known as snoring), clinically manifested as daytime sleepiness (due to sleep deprivation at night affects the daytime work, can endanger social security. The prevalence of the disease in the population is as high as 2%-4%), memory loss, and can induce a variety of diseases such as cardiac and cerebrovascular, and even cause accidental death, has become one of the important diseases that endanger human health in the 21st century. The diagnosis of snoring (OSAHS) is mainly based on polysomnography (PSG) to understand the severity of apnea, hypoventilation and hypoxemia. From the perspective of studying OSAHS, I have divided the upper airway into eight segments: nasal vestibule, intrinsic nasal cavity, nasopharynx, posterior soft palate, intertonsillar region, posterior tongue region, laryngeal cavity, and cervical trachea. If there is no clear stenosis dysfunction in each segment, treatment can be achieved through weight loss, exercise, change of sleep position and continuous positive pressure ventilation (CPAP). If there is stenosis in one or more segments of the upper airway, the first step is to surgically resolve the stenosis in the appropriate area, and then most patients will be cured naturally. However, in a small number of patients, who are still not well despite the stenosis resolution, further comprehensive treatment with continuous positive pressure ventilation via the nose is required. After years of clinical observation, the research paper “Clinical Significance of Soft Palate Formation with Partial Excision of Palatopharyngeal Muscle in the Treatment of (Snoring) OSAHS” was awarded as an excellent paper at the 14th National Academic Conference on Otolaryngology, Head and Neck Surgery of the Chinese Medical Association, and the procedure was also recognized by experts in the field.
