Sacral neoplasm resection is managed via partial or total sacrectomy that is performed via the Kraske approach. The combination of the patients positioning and the relatively long operative time required for this procedure increase the risk of pressure ulcers. Facial pressure ulcers can cause tissue necrosis and/or ulceration in a highly visible area, leading to a cosmetically disfiguring lesion. Here, the authors report the use of a Mayfield clamp in the positioning of patients undergoing sacral tumor resection to prevent facial pressure ulceration. After the patient is placed prone in the Kraske or Jackknife position, the hips and knees are flexed with arms to the side. Then while in the prone position, the patient is physically placed in pins, and the Mayfield clamp is fixated at the center of the metal arch via the Mayfield sitting adapter to the Andrews frame, suspending the head (and face) over the table. The authors find that this technique prevents the development of facial pressure ulcers, and it has the potential to be used in patients positioned in the Kraske position for other surgical procedures.
骶骨肿瘤切除术通过经克拉斯克入路施行的部分或全骶骨切除术来进行管理。该手术需要患者保持特定的体位,且手术时间相对较长,这增加了发生压疮的风险。面部压疮可导致在高度可见区域的组织坏死和/或溃疡,从而导致毁容性病变。在这里,作者报告了在接受骶骨肿瘤切除术的患者定位中使用 Mayfield 夹来预防面部压疮。患者取俯卧位,在克拉斯克或折刀位,然后将臀部和膝盖弯曲,将手臂置于身体两侧。然后,患者保持俯卧位,将身体固定在 pins 上,通过 Mayfield 坐式适配器将 Mayfield 夹固定在金属拱的中心,将头部(和面部)悬在手术台上。作者发现,该技术可预防面部压疮的发生,并且有可能用于在克拉斯克体位下接受其他手术的患者。
