The endoscopic endonasal approach to the infratemporal fossa (ITF) has gained popularity. However, the inferior turbinate and/or lacrimal duct are often removed when performing endoscopic medial maxillectomy for ITF approach, and there is potential risk for empty nose syndrome or epiphora. Although the endoscopic prelacrimal recess approach was introduced to avoid these complications, there were some limitations associated with surgical freedom. We report a 2-port endoscopic technique using both prelacrimal recess and antral window as a means to preserve the inferior turbinate and lacrimal duct, while facilitating instrument availability during ITF tumor resection. ⋯ We propose a hybrid endoscopic surgical procedure for ITF tumors using both endoscopic prelacrimal recess approach and transantral window. This technique provides surgeons an adequate working space via a bimanual technique through 2 different ports, while preserving normal sinonasal structures.
