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).
