To report a transoral freehand technique using continuous image guidance to biopsy a clival lesion.
The patient was placed in a Mayfield head rest. Patient data were registered using preacquired magnetic resonance and computed tomography images, and then, under continuous image guidance, a bone biopsy instrument was advanced freehand through a transoral route into the clival lesion.
Bone biopsy instrumentation was successfully placed into the clival lesion. Biopsy forceps were placed through the working channel of the biopsy instrumentation and specimen was successfully retrieved from the clival mass. The patient tolerated the procedure well and the only complaint was dysphagia, which resolved in several days postoperatively.
The transoral freehand technique with stereotactic navigation was found to be a simple, safe, fast, and effective way to biopsy a clival lesion.
报告一种使用连续图像引导经口徒手技术对斜坡病变进行活检的方法。
患者置于Mayfield头架上。使用预先获取的磁共振成像和计算机断层扫描图像对患者数据进行配准，然后在连续图像引导下，将骨活检器械经口徒手推进至斜坡病变处。
骨活检器械成功置入斜坡病变处。活检钳通过活检器械的工作通道置入，成功从斜坡肿物获取标本。患者对该操作耐受性良好，唯一的主诉是吞咽困难，术后数天缓解。
经口徒手立体定向导航技术是一种简单、安全、快速且有效的斜坡病变活检方法。
