UVPR, unscheduled voice prosthesis replacement; PVPR, prophylactic voice prosthesis replacement.
Data for the UVPR (2017–2019) and PVPR (2020–2022) periods are presented separately. The column “2017–2022 (Total)” shows cumulative values for the entire study period. “Median” represents the median number of procedures or hospitalization days per individual patient in each group. Total hospitalization days include both planned and complication-related admissions. The percentage of patients with hospitalization >14 days was calculated using a unified threshold for both groups. VPR, voice prosthesis replacement.
