Parapharyngeal space biopsy is an important investigation in the management of parapharyngeal space tumours. These tumours are relatively rare and the surgeon is often faced with a wide range of differential diagnoses. There are several ways to access the parapharyngeal space, with varying degrees of associated morbidity.
This paper describes a seldom used, but a simple and safe, image-guided endoscopic approach to parapharyngeal space biopsy that enables tissue to be obtained transnasally. The procedure is conducted under general anaesthesia using computed tomography image guidance via the LandmarX system, with transnasal access to the parapharyngeal space achieved using a sampling needle.
This procedure is relatively simple, safe and reproducible. It is a less invasive approach to parapharyngeal space biopsy, and one which has been successfully used by the senior author for years without any significant morbidity.
Transnasal image-guided endoscopic aspiration or biopsy of the parapharyngeal space is a novel technique that has not been previously described.
咽旁间隙活检是咽旁间隙肿瘤治疗中的一项重要检查。这些肿瘤相对罕见，外科医生常常面临多种鉴别诊断。有几种方法可进入咽旁间隙，相关的发病率各不相同。
本文描述了一种很少使用但简单安全的图像引导内镜下咽旁间隙活检方法，该方法能够经鼻获取组织。该手术在全身麻醉下进行，通过LandmarX系统使用计算机断层扫描图像引导，使用采样针经鼻进入咽旁间隙。
该手术相对简单、安全且可重复。它是一种侵入性较小的咽旁间隙活检方法，资深作者多年来成功使用该方法，未出现任何严重并发症。
经鼻图像引导内镜下对咽旁间隙进行抽吸或活检是一种此前未被描述的新技术。
