Modern concepts of tonsillectomy.

Tonsillectomy and adenoidectomy is still the most commonly performed surgical procedure in North America. The indications for surgery are constantly debated and seem to vary subjectively.

It is important to understand the pathophysiology of Waldeyer's ring and the changes brought about by recurring infections in the region. Treatment protocols vary, as do physician attitudes.
