Skull base surgery is an interdisciplinary subject. The anatomical structures in the skull base related to oral and maxillofacial surgery include parapharyngeal space, pterygopalatine fossa and infratemporal space. This operative area is one of the most challenging surgical areas in oral and maxillofacial surgery due to its deep site, complex anatomy and high risk. For skull base lesions, whether for preoperative biopsy or surgical treatment, there is a greater degree of difficulty and risk. Obtaining pathological information of the tumor preoperatively may help the surgeons optimize their treatment plan. Needle biopsy is one of the major minimally invasive ways to obtain the preoperative pathological results. The navigation technology, which is developing rapidly nowadays, provides a reliable assistance for deep tissue biopsy surgery. Experts from the Oral and Maxillofacial Surgery, Chinese Stomatological Association formulated an expert consensus on processes and operation of navigation-guided needle biopsy techniques for skull base tumors, so as to standardize and promote the application and operation of navigation-guided needle biopsy for skull base tumors.
颅底外科是一门交叉学科。与口腔颌面外科相关的颅底解剖区域主要包括咽旁间隙、颞下窝间隙和翼颌间隙。该区域位置深在、解剖结构复杂、手术风险高，是最具有挑战性的手术区域之一。颅底区的病变，无论是术前活检还是手术治疗均存在较大的难度和风险。术前获得肿瘤的病理学信息有助于制定治疗方案。穿刺活检手术是目前以微创手段获得病理结果的主要途径之一。快速发展的导航技术为深部组织穿刺活检手术提供了可靠的辅助手段。中华口腔医学会口腔颌面外科专业委员会组织专家，制定导航引导下颅底肿瘤穿刺活检技术操作的专家共识，规范导航技术在颅底肿瘤穿刺活检中的应用，以利其进一步推广应用。.
