OBJECTIVES: To determine the current practice, safety and efficacy of interventions used in the management of recurrent respiratory papillomatosis (RRP) in the UK NHS. DESIGN: Prospective registry (recruitment between 1st April 2018 and 31st August 2022, retrospective data from 1st January 2015 permitted with consent). Sub-group data-linked to Hospital Episode Statistics for additional follow-up (until 31st July 2022). SETTING: UK NHS hospitals treating RRP patients. PARTICIPANTS: Children and adults diagnosed with RRP and managed in an NHS hospital. MAIN OUTCOME MEASURES: Disease severity (Derkay, voice handicap and GRBAS scores), management (type and frequency of surgical and adjuvant intervention) and complications (cancer, death). RESULTS: Three hundred and thirty patients were entered into the registry; 304 (including 65 children) were eligible for analysis. Children had more severe disease than adults (median Derkay score 10 vs. 5). Microdebrider was the most common surgical intervention, particularly in children (86% of children, 49% of adults). Additionally, lasers (CO2, KTP and pulsed dye) were used in 34% of adults. Gardasil was the most common adjuvant therapy (21 children, 23 adults). Procedural complications were rare (10.8% children, 5.9% adults). Five patients developed laryngeal malignancy; there were six deaths during follow-up period. CONCLUSIONS: This is the largest UK RRP study to date. RRP is more aggressive in children than adults, and treatment choice differs between age groups. Overall, management was safe with minimal complications reported, and generally effective in maintaining a safe airway. Standardised reporting is required to objectively monitor disease progression and safety over time. TRIAL REGISTRATION: NCT03465280, ISRCTN36100560.
