Intranasal endoscopic prelacrimal recess approach for maxillary sinus inverted papilloma

Abstract

Purpose

This study aims to determine the indications and effectiveness of transnasal endoscopic prelacrimal recess approach (PLRA) in patients with maxillary sinus inverted papilloma (IP).

Methods

We retrospectively analyzed 71 patients treated in our institution for maxillary sinus IP between August 2008 and April 2015. 20 patients underwent endoscopic surgery via PLRA. All the patients who had postoperative follow-up for 3 years were enrolled. Demographic data, surgical technique, location of IP attachment, intra- and postoperative complications, follow-up duration and recurrence were recorded.

Results

The outpatient follow-up period was 3–10 years after surgery. Recurrence of IP was seen in 6 (8.5%) of 71 patients, including 1 patient in the PLRA group. The recurrence rate was 5% in the PLRA group. Six of 71 patients experienced postoperative complications, but none was observed in the PLRA group.

Conclusion

Transnasal endoscopic PLRA is a minimally invasive, safe and effective method for maxillary sinus IP. The indication for PLRA is tumor pedicle located on the antero-inferior or infero-lateral wall or at multiple attachment sites of the maxillary sinus.
