摘要目的:初步探索超声融合导航技术在咽旁－颞下窝－颅底(PIS)肿物穿刺活检中的应用价值。方法:研究纳入2021年3月至2022年3月中山大学附属第一医院需要明确病理诊断的PIS肿物患者8例[男性3例，女性5例，年龄16~76(50±20)岁]。应用超声与CT或MRI融合导航技术引导肿物穿刺活检，评估技术可行性、病理诊断率及并发症情况。结果:活检操作在8例患者中均成功实施，肿物大小2.2~6.5 cm。7例患者获得确切病理诊断，诊断率为87.5% (7/8)。术后无严重并发症。轻度并发症1例，发生率12.5%(1/8)。结论:超声融合导航技术在头颈深部肿物穿刺活检中具有较好的可行性、有效性和安全性。

abstractsObjective:To explore the value of ultrasound fusion navigation technology in the biopsy of parapharyngeal-infratemporal fossa-skull base (PIS) lesions.Methods:This study was conducted at the First Affiliated Hospital of Sun Yat-Sen University from March 2021 to March 2022 and included 8 patients [3 females and 5 males; age, (50±20) years; range, 16-76 years] with PIS lesions who needed to clarify the pathological diagnosis. The ultrasound fusion navigation with CT or MRI was used to guide lesion biopsy, and the technical feasibility, pathological diagnostic results and complications were evaluated.Results:The biopsy procedures were successful in all 8 patients, and the lesion size ranged from 2.2 to 6.5 cm. The exact pathological diagnosis was obtained in 7 patients, and the diagnostic rate was 87.5% (7/8). No major complication was observed after the biopsy. Mild complications occurred in 1 case, with a incidence of 12.5% (1/8).Conclusions:Ultrasound fusion navigation-guided biopsy is feasible, effective, and safe in the biopsy of deep head and neck lesions.
