Study design and setting
We retrospectively reviewed clinical records for all patients with
histologically confirmed inverted papilloma who received surgical
management under the care of the senior author at a tertiary rhinology
referral centre. Records were reviewed between 01/01/2011 - 31/12/2022.
This project was a local service evaluation and did not require ethical
approval, following completion of the NHS Research Ethics Committee
Tool, provided by the Medical Research Council. The STROBE guidelines
were adhered to for reporting.
