The surgery has been described since at least as early as 50 AD by Celsus. In the United States, as of 2010, tonsillectomy is performed less frequently than in the 1970s although it remains the second most common outpatient surgical procedure in children. The typical cost when done as an inpatient in the United States is US$4,400 as of 2013. There is some controversy as of 2019 as to when the surgery should be used. There are variations in the rates of tonsillectomy between and within countries.
