The objective of this study was to report the cases of three patients with sinonasal malignant tumors who underwent en bloc tumor resection using endoscopic endonasal approaches, and to discuss the advantages and limitations of endoscopic endonasal tumor resection.
Three patients with malignant naso-ethmoidal tumors underwent en bloc resection with endoscopic endonasal approach.
In very carefully selected cases of naso-ethmoidal malignant tumors that were preoperatively evaluated on endoscopic findings and magnetic resonance imaging to be limited to within the nasal cavity and/or ethmoid sinus and to have some safe margins between the tumor and skull base and/or lamina papyracea, tumors were resected en bloc using endoscopic endonasal approaches. A case of cerebrospinal fluid leakage was safely managed with the endoscopic approach.
In selected T1-T2 naso-ethmoidal malignant tumors with some safe margins, endoscopic endonasal surgery may offer a satisfactory alternative to external procedures.
本研究的目的是报告3例鼻窦恶性肿瘤患者采用鼻内镜经鼻入路整块切除肿瘤的病例，并探讨鼻内镜经鼻肿瘤切除的优点和局限性。
3例鼻筛恶性肿瘤患者采用鼻内镜经鼻入路进行整块切除。
在经过非常仔细挑选的鼻筛恶性肿瘤病例中，术前通过内镜检查结果和磁共振成像评估，肿瘤局限于鼻腔和/或筛窦内，且肿瘤与颅底和/或纸样板之间有一定安全切缘，采用鼻内镜经鼻入路整块切除肿瘤。1例脑脊液漏通过内镜方法得到妥善处理。
对于选择的具有一定安全切缘的T1-T2期鼻筛恶性肿瘤，鼻内镜经鼻手术可能是一种令人满意的替代外部手术的方法。
