Abstract
Adenotomy and tonsillectomy are commonly performed in pediatric patients, with obstructive sleep apnea being the most common indication. Because these surgeries are still associated with a relatively high risk of postoperative morbidity, surgeons tend to avoid cases when they are combined with other high risk factors, such as heart or pulmonary failure or infancy. Surgeries performed on nine children diagnosed with obstructive sleep apnea syndrome combined with high risk were reported. We suggest that careful diagnosis with polysomnography and precise informed consent before surgery, an operation using the newer technologies, and cooperation of the pediatrician and veteran anesthesiologists during the surgery lead to surgeries without incident.
