We investigated the role of a self-retaining retractor system, commonly used in ear, abdominal, vascular, urologic and gynecologic surgeries: the Lone Star retractor system. We report our experience in using the Lone Star retractor in different brain surgeries, at a single neurosurgical department.
In 2019, patients who underwent brain surgery and in which the Lone Star Retractor System was used were considered for inclusion. Clinical and surgical data of included patients were prospectively collected. Postoperative VAS for local pain, and a properly designed intraoperative retractor stability score, were collected.
Over 2019, the Lone Stare Retractor was used in 20 neurosurgical procedures: 9 high-grade glioma, 2 low-grade glioma, 4 cerebral metastases, and 5 meningiomas. Postoperative mean VAS score was 3.5 (range: 2-4). Intraoperative retractor stability score mean was 2 in frontal, 2 in pterional, 1.75 in subtemporal, 2 in interhemispheric, and 0.5 in suboccipital approaches. The Stony Brook Scar Evaluation Scale mean value was 4.4 (range: 3-5).
In our institutional experience, the Lone Star retractor showed many advantages in different brain procedures, when compared with standard fishhooks and other retractors.
我们研究了一种常用于耳科、腹部、血管、泌尿科和妇科手术的自固式牵开器系统： Lone Star 牵开器系统。我们报告了在单一神经外科部门使用 Lone Star 牵开器进行不同脑外科手术的经验。
2019 年，考虑纳入接受脑外科手术且使用 Lone Star 牵开器系统的患者。前瞻性收集纳入患者的临床和手术数据。收集术后局部疼痛视觉模拟评分（VAS）和专门设计的术中牵开器稳定性评分。
2019 年，Lone Stare 牵开器在 20 例神经外科手术中使用：9 例高级别胶质瘤、2 例低级别胶质瘤、4 例脑转移瘤和 5 例脑膜瘤。术后平均 VAS 评分为 3.5（范围：2-4）。术中牵开器稳定性评分平均为额部 2 分、翼点部 2 分、颞下窝部 1.75 分、半球间部 2 分和枕下部 0.5 分。Stony Brook 瘢痕评估量表平均评分为 4.4（范围：3-5）。
在我们的机构经验中，与标准鱼钩和其他牵开器相比，Lone Star 牵开器在不同的脑手术中具有许多优势。
