The clinical data of 7 patients (3 males and 4 females) with functional pituitary neuroendocrine tumor treated by endoscopic transnasal resection of the cavernous sinus medial wall from May to October 2023 in the Department of Neurosurgery of the First Affiliated Hospital of University of Science and Technology of China were retrospectively analyzed. They ranged in age from 29 to 60, with an average age of 45. The clinical diagnosis was acromegaly in 5 cases and Cushing's disease in 2 cases. There were 1 cases of microadenoma and 6 cases of macroadenoma. Knosp grade: Grade 1 adenoma in 3 cases, grade 2 adenoma in 3 cases and grade 3A adenoma in 1 case. Intraoperative resection of cavernous sinus medial wall was performed on the side of tumor. Five cases were determined to be invaded by tumor, and 2 cases were uncertain. No internal carotid artery injury occurred in all patients. The average intraoperative blood loss was 156 ml, and no patient was transfused. Postoperative endocrine remission was found in 6 cases, and tumor cells were found in 6 cases by pathological examination of the medial wall of cavernous sinus. No serious complications occurred in all patients. For Knosp grade 1-3 functional pituitary neuroendocrine tumor surgery, if there is no clear false envelope or normal pituitary between the tumor and the cavernous sinus medial wall during the operation, the cavernous sinus medial wall should be actively removed to improve the postoperative endocrine remission rate.
回顾性分析中国科学技术大学附属第一医院神经外科于2023年5—10月应用神经内镜经鼻海绵窦内侧壁切除技术治疗功能性垂体神经内分泌肿瘤7例患者的临床病例资料，男3例，女4例；年龄29~60岁，平均45岁。临床诊断为肢端肥大症5例，库欣病2例；微腺瘤1例，大腺瘤6例；Knosp分级：1级腺瘤3例、2级腺瘤3例、3A级腺瘤1例。术中均切除肿瘤侧海绵窦内侧壁，术中判断海绵窦内侧壁被肿瘤侵袭5例，不确定2例。所有患者均未发生颈内动脉损伤。术中平均出血量为156 ml，无患者输血。术后内分泌缓解6例，海绵窦内侧壁病理检查发现肿瘤细胞6例，所有患者术后均无严重并发症发生。对于Knosp 1~3级的功能性垂体神经内分泌肿瘤手术，若术中发现肿瘤与海绵窦内侧壁之间无明确的假包膜或正常垂体存在，应积极切除该侧海绵窦内侧壁，以提高术后内分泌缓解率。.
