Abstract
Sinonasal inverted papilloma, an uncommon benign neoplasm, tends to recur and is associated with malignancy. As endoscopic visualization has improved, inverted papilloma has been managed endoscopically through a transnasal approach, with recurrence rate similar to that in extranasal surgery. Transnasal endoscopic medial maxillectomy (TEMM) enables tumors to be removed completely, and lets the nasal cavity be better visualized postoperatively without skin or sublabial incision. Thus preserving the unaffected sinonasal framework, such as the anterior maxillary sinus wall, helps keep recurrent tumors from finding a preformed gateway for invading extranasal tissue. Our analysis of 5 such cases surgically resected with TEMM showed that. All tumors had been extirpated endoscopically and no recurrence was observed in follow-up. We find TEMM to be efficacious in treating inverted papilloma. Avoiding possible complications requires appropriate experience in endoscopic sinus surgery, and long-term follow-up is crucial to reporting long-term results.
