Application of cut needle biopsy to diagnosis of parapharyngeal space neoplasms

目的探讨穿刺切割活检术在咽旁间隙肿瘤诊断中的应用。方法对18例咽旁间隙肿瘤患者采用半自动活检枪进行穿刺切割活检术,以判断其诊断率。结果 17例患者得到确诊,诊断准确率94.4%(17/18),其中良性肿瘤13例,恶性肿瘤为4例;另1例患者因进针方向有误,诊断为纤维组织。所有患者均无并发症发生。结论咽旁间隙肿瘤穿刺切割活检术成功率和诊断符合率高,并发症少,有临床应用价值。

Objective To investigate the clinical application of cut needle biopsy （ CNB ） to the diagnosis of parapharyngeal space neoplasms. Methods CNB was performed with automatic biopsy gun on 18 cases with neoplasms of parapharyngeal space. Results Of all 18 patients, 17 patients had the right qualitative diagnosis. The diagnostic accuracy rates of benign and malignant neoplasms were 92.9% （ 13/14 ） and 100% （4/4） respectively, another patients diagnosed with fibrous tissue because of needling direction. No complications were recorded. Conclusion With advantages of high success rate, diagnostic accuracy and rare complications, CNB is worth being clinically applied to the diagnosis of neoplasms parapharyngeal space.
