In this study, 31 cases with different anterior skull base lesions mandating broad exposure, including the sphenoidal, parasellar, and clival region, were surgically treated using the frameless computer assisted surgery (CAS) system. The contribution of navigated surgery in relation to the broad exposure and direct visualization of this region rendered by the subcranial-subfrontal approach was evaluated. In group I, consisting of extensive tumors, the contribution of CAS was only given in five cases for the exposure of the tumor extensions located to the parasellar sphenoclival complex with concomitant distortion of the anatomic landmarks. No advantages were experienced in the more anterior locations along the ethmoidal compartment and frontal sinus. In the cases in group II, consisting of congenital anomaly implying fronto-orbital advancement and a meningoencephalocele as well as extensive mucoceles, the CAS was only helpful in those cases with an extremely aberrative anatomy in these regions.
在本研究中，31例因不同前颅底病变而需要广泛显露（包括蝶骨、鞍旁和斜坡区域）的患者，采用了无框架计算机辅助手术（CAS）系统进行手术治疗。评估了导航手术对于经颅下-额下入路实现该区域广泛显露和直接可视化的作用。在第一组，即由广泛肿瘤组成的组中，CAS仅在5例中有助于显露位于鞍旁蝶骨斜坡复合体且伴有解剖标志扭曲的肿瘤延伸部分。在筛窦隔和额窦更靠前的部位未发现优势。在第二组病例中，即由意味着额眶前移、脑膜脑膨出以及广泛黏液囊肿的先天性异常组成的组中，CAS仅在这些区域解剖结构极度异常的病例中有所帮助。
