Adenotonsillectomy remains one of the most common surgical procedures carried out in children. Though a commonly performed procedure, it poses a great challenge to the surgeon as well as the anaesthesiologist and is associated with a substantially increased risk of morbidity and mortality. In the post-operative period, it poses threats such as post-tonsillectomy bleeding and airway obstruction if not diagnosed and treated promptly. Various recent advances in airway management and early detection of post-operative complications have been made to reduce the sequelae associated with tonsillectomy. In this article, we have reviewed the various techniques, complications and recent advances, which have evolved in the anaesthetic technique related to adenotonsillectomy.
