Claudio Callejas

Claudio Callejas works in endoscopic skull base and sinus surgery, focusing on surgical approaches and reconstruction techniques for conditions like pituitary tumors, skull base defects, and sinonasal tumors. Much of the work involves developing and refining surgical techniques (such as new approaches to hard-to-reach areas of the skull base) and reporting on clinical cases and outcomes. This research is clinically oriented, often published as case reports, technique descriptions, and cadaveric anatomical studies relevant to neurosurgery and otolaryngology.

Publication output has fluctuated over the last decade with a notable increase in recent years (2024-2025), following a dip in 2023, suggesting an overall growing or resurgent pace of activity.
