Participants
Cases were identified from the operation logbooks of the Ears, Nose and
Throat (ENT) Department operating theatres. The following cases were
excluded:
- Pre-operative intracranial involvement – these were referred
externally to the local neurosurgical unit.
- Features of alternative sinus neoplasia, such as squamous cell
carcinoma, osteoma, or malignant melanoma.
- Conservative or palliative management as the sole treatment modality.
Practice at our centre is for primarily endoscopic resection of inverted
papillomata with the use of intraoperative Medtronic computer-assisted
navigation software.
