背景：自世纪首次描述以来，经蝶鞍入路治疗鞍区病变已经有了巨大的发展。内窥镜手术策略已成为外科手术设备的组成部分。最近，引入了具有更好图像分辨率的高清（HD）数码相机，尽管它们对外科手术的价值仍然不明确。本研究的目的是比较的图像质量的标准清晰度（SD）相机与一个新的HD camera.Methods：经蝶垂体腺瘤切除术同时记录在HD和SD分辨率。要求8名经验丰富的神经外科医生识别HD和SD中的预定义和非预定义解剖结构。此外，三个互补的手术序列的视频质量被评为等级从1（“非常好”）到6（“差”）。结果：平均23.6 +/- 2.7预定义的结构（84.38%）被确定在HD与17.6 +/- 4.4预定义的结构（62.95%）确定。解剖结构识别的这种深刻差异达到了统计学显著性（p = 0.012）。高清视频的视频质量主观印象评分为1.9、1.9和1.4，标清补充视频的主观印象评分为3.5、3.3和3.5。这些差异也达到了统计学意义（p
Background: The transsphenoidal approach to sellar lesions has evolved enormously since its first description in the early 20th century. Endoscopic surgical strategies have become an integral part of the surgical armamentarium. More recently, high-definition (HD) digital cameras with better image resolution were introduced, although their value for the surgical procedure remains equivocal. The purpose of this study was to compare the image quality of a standard-definition (SD) camera with a new HD camera.Methods: A transsphenoidal pituitary adenomectomy was recorded simultaneously in HD and SD resolution. Eight experienced neurosurgeons were asked to identify predefined as well as not predefined anatomic structures in HD and SD. Additionally, the video quality of three complementary surgical sequences was rated with grades from 1 ("very good") to 6 ("poor").Results: An average of 23.6 +/- 2.7 predefined structures (84.38%) were identified in HD versus 17.6 +/- 4.4 predefined structures (62.95%) identified in SD. This profound difference in the recognition of anatomic structures reached statistical significance (p = 0.012). Subjective impression of video quality was rated 1.9, 1.9, and 1.4 for the videos in HD and 3.5, 3.3, and 3.5 for the complementary videos in SD. These differences also reached statistical significance (p
