ObjectiveTo conduct a cost analysis of injection laryngoplasty performed in the operating theatre under local anaesthesia and general anaesthesia.MethodsThe retrospective study included patients who had undergone injection laryngoplasty as day cases between July 2013 and March 2016. Cost data were obtained, along with patient demographics, anaesthetic details, type of injectant, American Society of Anesthesiologists score, length of stay, total operating theatre time and surgeon procedure time.ResultsA total of 20 cases (general anaesthesia = 6, local anaesthesia = 14) were included in the cost analysis. The mean total cost under general anaesthesia (AU$2865.96 ± 756.29) was significantly higher than that under local anaesthesia (AU$1731.61 ± 290.29) (p < 0.001). The mean operating theatre time, surgeon procedure time and length of stay were all significantly lower under local anaesthesia compared to general anaesthesia. Time variables such as operating theatre time and length of stay were the most significant predictors of the total costs.ConclusionProcedures performed under local anaesthesia in the operating theatre are associated with shorter operating theatre time and length of stay in the hospital, and provide significant cost savings. Further savings could be achieved if local anaesthesia procedures were performed in the office setting.
