Popis: | A decision tree was constructed to determine the incremental cost-effectiveness ratio (ICER) of grafting techniques used to prevent Frey Syndrome. The authors performed a sensitivity analysis to calculate what the probability of preventing Frey Syndrome would have to be and maximum costs associated with using grafting techniques to warrant their use as more “cost-effective” choice than using neither. Decision pathways utilized were uses of (1) free fat graft (FFG), (2) acellular dermis, and (3) no grafting. The probability of developing Frey syndrome and costs were extracted from previous studies to construct the decision tree. The primary effectiveness was the ICER of FFG or acellular dermis to prevent Frey syndrome. The initial outcomes included preventing Frey syndrome (effectiveness = 1) or developing Frey syndrome (effectiveness = 0). Compared with not using a graft, the ICER of using FFG and acellular dermis were $10,628 and $50,813, respectively. Frey syndrome was found in 2.6% of patients postoperatively in FFG group, 9.8% of patients in acellular dermis group, and 30.7% of patients who did not have a graft. The ICER shows absolute dominance of FFG with lower cost and high effectiveness over acellular dermis. This economic evaluation strongly supports the use of FFG over acellular dermis as cost-effective approach for prevention of postparotidectomy Frey syndrome. |
