经口舌根病变外科治疗中术野显露的瓶颈与技术演进OA

Tongue base lesions are located deep within the oropharynx with intricate adjacent anatomical structures,and they border critical functional regions responsible for airway maintenance and swallowing.Poor surgical field exposure has long been the core bottleneck restricting the safety and radicality of surgical management for such lesions.Conventional open surgery involves significant trauma and results in unsatisfactory cosmetic outcomes.Although laser and coblation technologies have greatly advanced minimally invasive treatment,they still fail to overcome limitations regarding deep surgical visualization and blind operating zones.Transoral robotic surgery(TORS),leveraging its advantages of three-dimensional high-definition visualization,flexible robotic arms,and precise manipulation,offers a novel technical platform for improving exposure of deep lingual lesions and enhancing the safety of resection of complex tongue base lesions.This commentary reviews the exposure challenges,mainstream technical approaches and developmental trends of transoral surgery for tongue base lesions,aiming to provide theoretical references for surgical procedure selection and standardized therapeutic protocols.
