Age
18 Years to 65 Years
Inclusion criteria
Inclusion criteria: 1. Aged between 18 and 65; 2. Diagnosis of SAS: The diagnostic criteria for sleep apnea syndrome (SAS) mainly rely on symptoms, signs, and the results of polysomnography (PSG). The core indicator is the occurrence of >=5 apnea or hypopnea events per hour during sleep (AHI >=5 events/hour), accompanied by related symptoms or health risks; 3. Diagnosed with SAS and SAS I–III; 4. Agree to sign the informed consent form.
Exclusion criteria
Exclusion criteria: 1.For any reason, if a subject is unable to cooperate with the research or if the researcher deems it inappropriate for the subject to be included in this trial. 2.Patients with contraindications for awake bronchoscopy intubation (patients who are awake but tense or confused and estimated to be unable to cooperate; patients allergic to local anesthetics; patients with frequent bronchial asthma; patients with active bleeding in the airway and opaque secretions); 3.There are contraindications for superior laryngeal nerve block (infection at the puncture site, cervical mass, allergy to local anesthetics, severe bleeding tendency, and inability to cooperate). 4.Patients with a history of allergy to the drugs involved in this study; 5.Patients with persistent cough and upper respiratory tract infection before surgery; 6.The past medical history includes factors that should not be included in the study (such as patients who have undergone laryngeal cancer surgery, received laryngeal radiotherapy, have coronary heart disease, or suffer from asthma, etc.).
