OBJECTIVE: To determine the efficacy of the Gyrus diego microdissector at increasing oscillation speeds, using an in vitro tissue model.
BACKGROUND: It had not previously been established whether microdissectors were more efficient at higher or lower speeds.
METHODS: We investigated the effect of varying microdissector oscillation speeds on the weight of material aspirated in a given time. A 4 mm straight blade was used with constant suction strength. Jelly and liver were used to simulate polyps and muscle plus connective tissue, respectively. Water was used as a control. Repeat readings were taken at speeds of 1000, 2000, 3000, 4000 and 5000 rpm. Data were analysed using linear bivariate regression.
RESULTS: The results showed significant linear trends in the cases of liver and jelly, with faster cutter speeds being associated with higher aspiration rates.
CONCLUSION: These results suggest that microdissector efficacy increases with speed, up to 5000 rpm.
