writing "Those who extirpate the entire tonsil remove, at the same time, structures that are perfectly healthy, and, in this way, give rise to serious Hæmorrhage". In the 7th century Paulus Aegineta (625–690) described a detailed procedure for tonsillectomy, including dealing with the inevitable post-operative bleeding. 1,200 years pass before the procedure is described again with such precision and detail. The Middle Ages saw tonsillectomy fall into disfavor; Ambroise Pare (1509) wrote it to be "a bad operation" and suggested a procedure that involved gradual strangulation with a ligature. This method was not popular with the patients due to the immense pain it caused and the infection that usually followed. Scottish physician Peter Lowe in 1600 summarized the three methods in use at the time, including the snare, the ligature, and the excision. At the time, the function of the tonsils was thought to be absorption of secretions from the nose; it was assumed that removal of large amounts of tonsillar tissue would interfere with the ability to remove these secretions, causing them to accumulate in the larynx, resulting in hoarseness. For this reason, physicians like Dionis (1672) and Lorenz Heister censured the procedure. In 1828, physician Philip Syng Physick modified an existing instrument originally designed by Benjamin Bell for removing the uvula; the instrument, known as the tonsil guillotine (and later as a tonsillotome), became the standard instrument for tonsil removal for over 80 years. By 1897, it became more common to perform complete rather than partial removal of the tonsil after American physician Ballenger noted that partial removal failed to completely alleviate symptoms in a majority of cases. His results using a technique involving removal of the tonsil with a scalpel and forceps were much better than partial removal; tonsillectomy using the guillotine eventually fell out of favor in America. In the beginning of the 20th century, tonsillectomy became more common in the United Kingdom and the United States and by the 1930s was very common in both countries. For example, a study conducted in 1934 found that 61% of 1,000 New York schoolchildren had been tonsillectomized; doctors recommended surgery for all but 65 of the remaining children. Complications were often simply accepted. The medical community considered enlarged tonsils a disease, attributing their enlargement to infection rather than a physiologic response. Because of the theory of focal infection, many surgeons believed that not only enlarged tonsils, but all
