When adenoid hypertrophy causes snoring, sinusitis and facial developmental deformities, surgical treatment is required. Adenoid surgery is mostly performed on children, usually under general anesthesia, so coughing before adenoid surgery cannot be operated. Because coughing indicates inflammation of the upper respiratory tract, intubation can bring the inflammation of the upper respiratory tract into the trachea with the intubation, causing infection of the lower respiratory tract, increasing the chance of infection, which is not conducive to the recovery of the disease. In addition, the trauma is exposed after adenoid surgery, when coughing will cause trauma bleeding, increasing the uncertainty of surgical safety, so coughing under general anesthesia for adenoidectomy is unsafe, should not be carried out surgery.
