Abstract：
Recently, cone-beam computed tomography (CBCT)-guided surgeries have been developed for bone and soft tissue tumors. The present study aimed to evaluate the efficacy of CBCT-guided curettage for osteoid osteoma. Our study population included 13 patients who underwent primary curettage for osteoid osteoma using intraoperative CBCT in a hybrid operating room between April 2019 and November 2022. We collected the following data: sex, age, follow-up period, symptom onset to time of surgery, tumor size and location, length of skin incision, operating time, radiation dose, recurrence, postoperative complications, and visual analog scale for pain during the last follow-up. There were 10 male and 3 female patients, and the mean age was 25.0 years (range, 9-49 years). The mean follow-up period was 10.6 months (range, 0.4-24.0 months). The locations of the tumors were the proximal femur in 6 patients, the acetabular region in 2 patients, and the ilium, tibial shaft, calcaneus, cuboid, and talus in 1 patient each. The mean time of symptoms onset to surgery was 18.7 months (range, 2.3-69.9 months). The mean maximum diameter of the tumor was 5.9 mm (range, 3.5-10.0 mm). The mean length of the skin incision was 2.2 cm (range, 1.5-3.5 cm). The mean operating time was 96.9 minutes (range, 64-157 minutes). The mean dose of radiation was 193.2 mGy (range, 16.3-484.0 mGy). No recurrences, postoperative complications, and reoperation were observed in this study. All the patients reported 0 mm on the visual analogue scale for pain on the last follow-up. CBCT-guided curettage for osteoid osteoma was minimally invasive and reliable. This procedure can be effective for the treatment of lesions found in deep locations such as the pelvic bone and proximal femur or an invisible lesion that cannot be detected by regular fluoroscopy.
摘要：
最近,已经开发了用于骨和软组织肿瘤的锥形束计算机断层扫描（CBCT）引导手术。本研究旨在评估CBCT引导下刮除治疗骨样骨瘤的疗效。我们的研究人群包括13例患者，他们在2019年4月至2022年11月之间在混合手术室中使用术中CBCT进行骨样骨瘤的初次刮除。我们收集了以下数据：性别，年龄,随访期,症状发作到手术时间，肿瘤大小和位置，皮肤切口长度,操作时间,辐射剂量,复发,术后并发症,最后一次随访时疼痛的视觉模拟量表。有10名男性和3名女性患者，平均年龄为25.0岁(范围，9-49岁）。平均随访期为10.6个月(范围，0.4-24.0个月）。6例患者的肿瘤部位为股骨近端,2例患者的髋臼区域，和髂骨，胫骨干,跟骨,长方体,和距骨各1例。手术后症状发作的平均时间为18.7个月（范围，2.3-69.9个月）。肿瘤的平均最大直径为5.9mm（范围，3.5-10.0毫米)。皮肤切口的平均长度为2.2cm（范围，1.5-3.5厘米）。平均手术时间为96.9分钟(范围，64-157分钟）。平均辐射剂量为193.2mGy(范围，16.3-484.0mGy）。没有复发,术后并发症,在这项研究中观察到了再次手术。所有患者在最后一次随访时的疼痛视觉模拟评分为0mm。CBCT引导下刮除骨样骨瘤微创、可靠。该程序可以有效地治疗在深位置发现的病变，例如骨盆骨和股骨近端或无法通过常规透视检查检测到的不可见病变。
