This can make breathing difficult and often leads to an emergency or preventive tracheostomy (\"wind-pipe\") surgery.\n\nWhat: This study will test two simple ways to avoid a tracheostomy:\n\nPre-operative BiPAP sleep training - patients practice sleeping with a non-invasive BiPAP breathing machine for seven nights before surgery so they become comfortable with the mask and pressures.\n\nImmediate post-extubation BiPAP support - the same BiPAP machine is started as soon as the breathing tube is removed in the operating room or recovery area.\n\nHow: Adults (18-80 years) who already have, or are at high risk of getting, BVCP will be randomly assigned to one of four groups in a 2 × 2 design:\n\n• Group 1: training + post-op BiPAP • Group 2: training only • Group 3: post-op BiPAP only • Group 4: standard care (no planned BiPAP).\n\nMain goal: To find out whether either or both BiPAP strategies reduce the need for tracheostomy or re-intubation during the first 7 days after surgery.\n\nWhat participants do: Eligible patients will undergo routine surgery plus the assigned BiPAP plan. Breathing events, comfort, hospital stay, and voice quality will be recorded up to 6 months.\n\nPotential benefit\u002Frisk: BiPAP is non-invasive and already FDA-cleared for home and hospital use, but some people may feel mask discomfort or air leaks. Trained staff will adjust settings and stop BiPAP if serious problems occur.",[27,28,29,30],"Vocal Cord Paralysis, Bilateral","Airway Obstruction, Postoperative","Thyroid Neoplasms","Sleep Apnea, Obstructive",[32,33,34,35,36,37,38,39,40,41],"BiPAP","Non-invasive Ventilation","Continuous Positive Airway Pressure","Peri-operative Airway Management","Tracheostomy Avoidance","Thyroidectomy","Neck Surgery","Glottic Stenosis","Pre-operative Sleep Training","Voice Handicap Index","NOT_YET_RECRUITING","2025-06-27",{"date":45,"type":46},"2025-06-29","ACTUAL",{"date":48,"type":21},"2025-07-01",{"date":50,"type":21},"2029-12-31",{"name":52,"class":53},"Fujian Medical University","OTHER",""]
