Lesions of the orbital apex often present a diagnostic dilemma. Clinical assessment and imaging studies are helpful but a tissue biopsy is often required. The morbidity associated with transcranial approaches to the orbital apex may outweigh the benefits of obtaining a biopsy by these routes. Fine needle aspiration cytology of orbital apex lesions can be performed but there are disadvantages with this method. We describe a transnasal endoscopic technique to biopsy the orbital apex. The technique was used successfully to obtain a tissue diagnosis in six patients with orbital apex lesions. This enabled commencement of definitive treatment. There were no significant complications. The transnasal approach to the orbital apex using the endoscopes is reliable. Endoscopes provide excellent illumination, magnification, and a panoramic view of the operative field.
眶尖病变常常带来诊断难题。临床评估和影像学检查虽有帮助，但通常需要进行组织活检。经颅入路至眶尖的相关发病率可能超过通过这些途径获取活检的益处。可对眶尖病变进行细针穿刺细胞学检查，但该方法存在缺点。我们描述一种经鼻内镜技术用于眶尖活检。该技术成功用于6例眶尖病变患者以获得组织诊断。这使得能够开始确定性治疗。没有显著并发症。使用内镜经鼻入路至眶尖是可靠的。内镜提供出色的照明、放大及手术视野全景。
