The proposed study will randomly select children undergoing cleft palate repair to have tisseel used on the incision. Through statistical tests 40 children will be recruited (20 to have tisseel used and 20 with no tisseel). The use of tisseel will be known to the surgeon but not to the recovery room or ward nursing staff. Post operatively, the FLACC pain scale will be used to score the pain of the children throughout their admission to the Stollery children's hospital. The amount of pain controlling medication required as well as time to discharge will also be recorded. Statistical analysis of the data will be performed using accepted methods. Overall, the investigators hope to show that fibrin sealant, tisseel, will less the amount of post operative pain experienced by children undergoing cleft palate repair.
