Synthesis of Results
Of the 20 studies, only one directly compared three kinds of treatments
of RRP,and two studies compared microdebrider to CO2 laser treatment of
RRP, analyzing the complications tape and complication rate between the
two treatment settings. The remaining 17 studies analyzed the outcome
measures in one of the three treatment modalities only. In the study
which compared three kinds of treatments, patients in the KTP laser
group had been treated in the hospital multiple times prior to inclusion
in the study, and calculating postoperative complication rate data on
this basis was unreliable and therefore excluded from the KTP group
study. Overall, 14 studies were CO2 laser treatment, while 6 studies
were microdebrider treatment, and 5 studies assessed KTP laser. There
are 161 patients with RRP were treated by microdebrider, a total of 605
patients with RRP were treated by CO2 laser, while a total of 106 were
treated by KTP laser.
