The AAO-HNSF Clinical Practice Guideline: Tonsillectomy in Children provides evidence-based recommendations on the pre-, intra-, and postoperative care and management of children aged 1-18 years under consideration for tonsillectomy. Tonsillectomy is one of the most common surgical procedures in the USA with over 289,000 procedures performed annually in children under 15 years of age. Tonsillectomy is defined as a surgical procedure performed with or without adenoidectomy that completely removes the tonsil including its capsule by dissecting the peritonsillar space between the tonsil capsule and the muscular wall. This guideline is intended for all clinicians in any setting who interact with children aged 1-18 years who may be candidates for tonsillectomy. Learning Objectives: 1.Gain insights to decrease harmful variation in care for tonsillectomy patients. 2. Improve quality of care outcomes for tonsillectomy patients. 3. Understand the existing variations in practice and the quality to improve patient care. Faculty: Ron B. Mitchell, MD(Nothing to disclose), Sanford M. Archer, MD(Consulting Fees: OptiNose), Stacey L.
