Indications and outcomes of adenoidectomy in infancy.

Adenoid hypertrophy is one of the most common causes of pediatric obstructive sleep apnea. Although adenoidectomy is the only effective treatment for adenoid hypertrophy, it is rarely performed in infants less than 1 year old. This study reports on the successful use of adenoidectomy in 24 infants less than 1 year old with a triad of upper airway obstruction symptoms, findings of obstructing adenoids, and obstructive sleep apnea (but no other anomalies). This is a retrospective case series reviewing each infant's clinical data, including presenting symptoms (with special emphasis on apnea episodes), physical examination findings, and results of other investigations such as polysomnography, endoscopy, pH-metry, and echocardiography. With careful preoperative and postoperative monitoring, the 24 infants underwent adenoidectomy without complications. After the procedure, all showed marked improvement with complete disappearance of symptoms of upper airway obstruction, failure to thrive, and gastroesophageal reflux disease. Adenoidectomy was found to be sufficient and curative for such infants.
