About

Dr. Yung-An Tsou is a leading otolaryngologist and sleep surgeon whose research focuses on advancing surgical treatments for obstructive sleep apnea syndrome (OSAS). His major contributions center on the comparative efficacy of minimally invasive techniques, particularly transoral robotic surgery (TORS) for tongue base reduction. In his highly cited 2019 study (17 citations), Dr. Tsou directly compared TORS with coblation-assisted tongue base reduction, establishing TORS as a viable, precise alternative for managing retroglossal airway collapse. He further expanded this work in 2020 (14 citations) by systematically comparing TORS against other surgical modalities, providing a comprehensive framework for surgical decision-making. Notably, his 2021 study (13 citations) explored multilevel surgery, combining TORS tongue base resection with either modified uvulopalatopharyngoplasty or barbed reposition pharyngoplasty, addressing the complex reality of multilevel collapse seen in drug-induced sleep endoscopy. Through these studies, Dr. Tsou has helped refine surgical protocols, demonstrating that targeted, robotic-assisted multilevel approaches can improve outcomes for moderate-to-severe OSA patients. His work bridges the gap between technological innovation and clinical practice, offering surgeons evidence-based guidance for personalized airway surgery.
