Comparison of the time between operations for RRP with three surgical modalities
According to the surgical method, the surgical cases were divided into three treatment groups, namely microdebrider, CO2 laser and KTP laser group. The comparison of the operation intervals of the three surgical methods is shown in fig.2.C.
In the JO-RRP group, the interval between procedures for microdebrider was 124.7±114.5 days, for CO2 laser group 186.2±140.1 days, and for KTP laser group 139.2±108.3 days.
The difference between CO2 laser and microcutter was statistically significant (p=0.011). CO2 laser had a larger interval between operations than KTP laser, but there was no significant difference(p>0.05). KTP laser had a larger interval between operations than microdebrider after treatment, but there was no significant difference(p>0.05).
