Obstructive sleep apnea hypoventilation syndrome (OSAHS), also known as snoring, is a chronic sleep respiratory disease characterized by recurrent complete or incomplete upper airway obstruction during sleep, accompanied by intermittent hypoxemia, hypercarbia and sleep structure disorders. In 2002, the Sleep Respiratory Disease Group of the Shanghai Medical Association conducted an epidemiological survey on the prevalence of obstructive sleep apnea hypoventilation syndrome in people over 30 years of age in Shanghai, and the results showed that the prevalence of OSAHS in the Shanghai population was 3.62%. OSAHS seriously affects people’s life expectancy. Overseas clinical statistics show that the 5-year mortality rate of untreated OSAHS patients is as high as 11% to 13%, and the 8-year mortality rate of those with apnea and hypoventilation index (AHI) higher than 20 is 37%. OSAHS patients are two to seven times more likely to be involved in traffic accidents than control subjects. Since the 1980s, our hospital has been engaged in the diagnosis and treatment of obstructive sleep apnea syndrome. In 2001, we established a special specialty of diagnosis and treatment of obstructive sleep apnea hypoventilation syndrome, and currently have 4 beds for polysomnography (PSG) examination, with an annual average of about 1,000 examinations and about 200 inpatient procedures, and have performed more than 2,000 procedures. We are the first in China to carry out Pillar biological nail implantation, low temperature plasma radiofrequency assisted palatopharyngoplasty, Z-shaped palatopharyngoplasty, chin-lingual muscle advancement hyoid suspension (GAHM), chin-spin ring drill system chin-lingual muscle advancement, simultaneous UPPP + GAHM surgery and maxillary and mandibular advancement, and to establish a comprehensive sequence of individualized treatment plan for OSAHS, which has achieved good results with an overall efficiency of nearly The overall efficiency is nearly 80%, among which the efficiency of maxillary and mandibular advancement is 100%. Recently, we have carried out oral orthodontic appliance treatment for patients with surgical failure, and the patients’ subjective feedback is good, and the objective efficacy is being evaluated in follow-up. He has published dozens of academic papers in authoritative journals at home and abroad, and has edited one monograph and participated in several monographs.
