They were asked (1) their age, (2) the age at tonsillectomy, (3) where the operation was done, (4) whether the surgeon was a "nose and throat" specialist, (5) why the operation was performed, (6) what anesthetic was used, (7) whether any benefit was obtained, and (8) whether to their knowledge any tonsillar tissue was left. Then the pharnyx was carefully examined with the use of a good light, a metal tongue depressor, and a tonsil pillar re¬ tractor.…”
