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.
