Journal for oto-rhino-laryngology and its borderlands Background: Endoscopic middle meatal antrostomy (EMMA) is considered the standard approach for surgical management of antrochoanal polyps (ACPs). Recently, an endoscopic inferior meatal antrostomy (EIMA) approach for clearing lesions in the maxillary sinus was described. In this study, we compared the long-term outcome of patients with ACP following surgical treatment using one of these 2 approaches (EIMA or EMMA). Methods: The medical charts of all patients treate d for ACPs in our institution between January 1, 2009, and July 1, 2020, were reviewed retrospectively. Patients were invited to complete a long-term follow-up assessment. Results: Thirty-eight patients were included in the study: EIMA was the only procedure performed in 25 patients (66%) and EMMA was the only procedure performed in 7 patients (18%). Both procedures were performed in 6 patients (16%): 2 patients (5%) underwent simultaneous EMMA and EIMA for better access and visualization and 4 patients (10.5%) underwent surgical revision consisting of EIMA secondary to failed EMMA at other institutions. Median follow-up was 44 months (range, 6 months–11 years). No evidence of recurrent ACPs, recirculation, synechiae, nasolacrimal duct injury, or bleeding was observed in any of our patients. Small nonobstructing cysts were observed in 2 patients (8%) following EIMA. Conclusions: EIMA prevents violation of the ostiomeatal complex. It provides access to t he anteroinferior aspect of the maxillary sinus and should be considered as an alternative to EMMA in patients with ACPs. ORL View on the web Inoreader.
