Summary
Bilateral inverted papilloma (IP), a rare nasal tumor, was successfully treated with endoscopic medial maxillectomy. This endoscopic sinus surgery approach is effective for IP, even when extensive.
Area of Science:
- Otolaryngology
- Neurosurgery
- Oncology
Background:
- Inverted papilloma (IP) typically affects one side of the nasal cavity and paranasal sinuses.
- Bilateral inverted papilloma is exceptionally rare and can mimic malignancy.
Purpose of the Study:
- To report a rare case of extensive bilateral inverted papilloma.
- To highlight the successful surgical management of this rare condition.
Main Methods:
- The study describes a case of a large bilateral inverted papilloma.
- Treatment involved bilateral endoscopic medial maxillectomy (EMM).
Main Results:
- The patient presented with a large bilateral inverted papilloma mimicking malignancy.
- Successful surgical removal was achieved via bilateral EMM.
- The patient remained disease-free 24 months post-surgery.
Conclusions:
- Endoscopic sinus surgery (ESS), including EMM, is a primary treatment choice for inverted papilloma.
- ESS is recommended when preoperative diagnosis does not suggest malignancy in IP cases.
