Abstract Background Surgical debulking remains the mainstay of treatment of adult-onset recurrent respiratory papillomatosis (AO-RRP). But there are no guidelines for decision-making of surgical modality. Objectives This retrospective study aims to obtain a better understanding of AO-RRP, and select the best surgical modality for RRP among microdebrider, CO2 laser, and KTP laser. Material and methods Medical records of 72 AO-RRP patients were reviewed, with at least a 6-month follow-up. We focused on demographic data, the median treatment intervals (MTI) (Days), the survival curves, and treatment-related complications. Results Seventy-two AO-RRP and a total of 172 surgical procedures were included, with either the microdebrider (n = 46), CO2 laser (n = 102), or KTP laser (n = 24). The MTI of all patients was 230.0[132.0, 455.0] (median[P25-P75]), with microdebrider group (267.50[152.5, 449.5]), CO2 laser group (247.5[145.5, 474.7]), and KTP laser group (107.5[68.3, 330.5]), and there were no significant differences among three surgical modalities on MTI or survival curves (p > .05). The duration of surgery was 44.9[25.6] in the microdebriders group, 48.4 [29.5] in the CO2 laser group, and 51.3[18.4] in the KTP laser group, but there was no significant difference in the operation duration among the three groups (p > .05). Postoperative glottic webs and scar formations were found in 4.3% of patients in microdebrider group, 16.7% of patients in CO2 laser group, and 8.3% of patients in KTP group. Conclusion and Significance Microdebrider surgery for RRP took the shortest time and had the lowest rate of postoperative complications. However, different surgical modalities are equally effective in controlling recurrence after RRP surgery.
