The efficacy of cryotherapy for pharyngeal pain after tonsillectomy was studied.The pain of 10 patients after tonsillectomy was controlled by the usual methods; i. e., neck icing, povidone iodine gargling, inhalation of aerosols containing antibiotics and corticosteroids, and administration of mefenamic acid syrup perorally (control group). In addition to these treatment methods, another 10 patients received shaved ice orally 30 minutes before each meal (ice group).The pharyngeal pain of each patient was scored 5 times a day by the 10 cm analog scale and the 4 grades of classification. Scoring occurred at waking, 10, 14, 18, and 21 o' clock. The amount of food each patient could eat was also recorded.The pain scores at waking were significantly reduced in the ice group on the 2nd and the 4th post-operative day (p < 0.05; Welch's t-test). The pain was the most severe at waking, diminished during the daytime, and was somewhat increased at night again in both groups (p < 0.05; one-way ANOVA). The patients in the ice group were advanced to more solid and more nutritive diets earlier than those in the control group.We concluded that pharyngeal cryotherapy after tonsillectomy was useful for pain control after tonsillectomy, and the analog scale was suitable for continual recording of the pain levels of patients.
