概要	BACKGROUND:Endoscopic transnasal surgery (ETS) has become an established treatment for skull base lesions; however, its lateral reach to the pterygopalatine fossa (PPF) and infratemporal fossa (ITF) remains limited due to restricted maneuverability within the nasal corridor. To address this limitation, the endoscopic modified medial maxillectomy (EMMM) and the direct approach to the anterior and lateral part of the maxillary sinus (DALMA) provides lateral access through the maxillary sinus. This study evaluated the technical feasibility and outcomes of ETS combining EMMM and DALMA.CONCLUSIONS:Combining EMMM and DALMA approaches provides a safe and minimally invasive option for treating lesions extending laterally into the ITF and PPF
