About

Pei-Jen Lou is a pioneering head and neck surgeon whose research centers on minimally invasive robotic techniques for salivary gland disorders, with a particular focus on gland-preserving surgery. Her major contribution lies in demonstrating the feasibility and safety of robotic resection for benign submandibular gland tumors, challenging the traditional open surgical approach that often sacrifices the entire gland. In her landmark 2014 study comparing robotic and open techniques, Lou showed that robotic surgery achieves comparable tumor control while significantly reducing scarring, operative time, and hospital stays—preserving both gland function and patient quality of life. This work, cited 18 times, has helped establish robotic submandibular gland surgery as a viable alternative in select cases. Beyond this, Lou has advanced the field through studies on transoral robotic surgery for oropharyngeal cancers and innovative approaches to parotid gland tumors. Her research bridges the gap between oncologic safety and functional preservation, making her a key figure in the evolution of head and neck robotic surgery. For students and researchers, Lou’s work exemplifies how surgical innovation can transform patient outcomes while maintaining rigorous oncologic standards.
