This technical note presents the advantages of a modified nasal speculum for the translabial-endonasal transsphenoidal approach to the sphenoid sinus and sella for surgery on lesions of the pituitary. The width of the upper lateral wings of the speculum was reduced by half over approximately three fourths of their length. This increases interior clearance and makes it easier to introduce the instruments used during transsphenoidal operations. We performed 50 transsphenoidal procedures for pituitary adenomas using the remodeled speculum. Three experienced surgeons evaluated the visual field and instrument passage through it, and they found it superior to the conventional design. The modification resulted in marked reduction of the overall operation duration. In conclusion, the more open translabial-transnasal speculum described here definitely facilitates the transsphenoidal approach to the pituitary.
本技术说明介绍了一种改良鼻窥器在经唇-鼻内经蝶窦入路至蝶窦和鞍区进行垂体病变手术中的优势。窥器上侧翼的宽度在其长度的约四分之三范围内减少了一半。这增加了内部间隙，使经蝶窦手术中使用的器械更容易插入。我们使用改良后的窥器对50例垂体腺瘤进行了经蝶窦手术。三位经验丰富的外科医生评估了视野和器械通过情况，他们发现改良后的窥器优于传统设计。这种改良显著缩短了总体手术时间。总之，此处描述的更开放的经唇-经鼻窥器确实有助于经蝶窦入路治疗垂体疾病。
