Tonsillectomy is one of the most common otolaryngologic procedures performed. Unfortunately, it can be associated with a prolonged and difficult postoperative recovery; postoperative vomiting has been reported in up to 75% of patients. Return to normal activities and oral intake can take up to 2 weeks. Therefore, attempts have been made to both minimize anesthetic adverse effects and improve the postoperative course. For example, Telian et al1 reported a decrease in posttonsillectomy symptoms with the use of intraoperative ampicillin and postoperative amoxicillin.
