It is difficult to identify through images, prior to surgery the implantation site in the maxillary sinus and sometimes even in the surgery.

This is important to be able to resect the implantation of the polyp and reduce the recurrences. Different endonasal approaches have been described.

Objective: To determine if the endonasal prelacrimal approach with endoscopes was effective in resecting antrochoanal polyps and reducing recurrences.

Design: Descriptive and prospective.

Methods: Patients treated for antrochoanal polyps using an endonasal prelacrimal approach with endoscopes between September 2021 and March 2024 were include.

Results: Eight patients were operated. The prelacrimal approach was used alone in four patients, while in the other four, it was combined with a medial maxillary antrostomy.

Conclusions: The endonasal pre-lacrimal approach to the maxillary sinus is a suitable surgical technique for exposing the anterior and anterolateral sectors of the maxilla. Alone or combined with a medial antrostomy, it allows visualization of all walls of the maxillary sinus and complete resection of antrochoanal polyps, including their site of implantation. It is a safe technique with few complications and provides a high rate of complete resection in cases of antrochoanal polyps
