Is the KTP laser effective in tonsillectomy?

Thirty-eight patients underwent a randomized double-blind trial using the KTP laser for tonsillectomy on one tonsil and standard dissection tonsillectomy on the other tonsil. Blood loss was less on the laser side. However, pain though initially slightly less on the laser side (days 1 and 2 post-operation) was worse on the laser side at 2 weeks due to delayed healing of the tonsillar bed. There were no primary or reactionary haemorrhages but a 15% incidence of secondary haemorrhage on the laser side.
