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.
