Objective:To investigate the surgical approach for the resection of juvenile nasopharyngeal angiofibroma（JNA） under nasal endoscopy. Methods:The clinical data of 87 patients undergoing endoscopic resection of nasopharyngeal fibroangioma were retrospectively analyzed. We classified JNA according to tumor site, size, invasion scope and anatomic position relationship between tumor and midline of pupil. Three endoscopic surgical approaches were selected according to the classification, and the postoperative symptoms, complications and recurrence were investigated and analyzed. Results:The tumor resection rate of 87 cases by nasal endoscopic surgery was 100%. Thirty-five cases were approached through the middle nasal passage（small tumors located in the nasal sinuses and pterygopalatine fossa）, forty-five cases were approached through the lateral wall of the nasal cavity（tumor invaded the pterygopalatine fossa but did not exceed the midline of the pupil） , and seven cases were approached via the lateral wall of nasal cavity + ipsilateral anterior wall of maxillary sinus（tumor invaded the infratemporal fossa beyond the midline of pupil or invaded the cavernous sinus and the middle cranial fossa epidural）, Postoperative patients with nasal congestion, nasal bleeding, headache, dizziness, vision loss and other symptoms showed varying degrees of improvement. No surgical death or intracranial infection occurred. The postoperative follow-up was 6-78 months, and the recurrence rate was 3.44%. Conclusion:Endoscopic resection of nasopharyngeal fibroangioma is the main treatment method for JNA. Selecting suitable endoscopic approach to resect JNA, To maximize the advantage of nasal endoscopic equipment according to the inherent anatomical space of the human nasal cavity, In order to achieve the purpose of JNA resection, reduce intraoperative and postoperative complications, reduce the recurrence rate and improve the prognosis.
目的：探讨经鼻内镜手术入路切除鼻咽纤维血管瘤（juvenile nasopharyngeal angiofibroma，JNA）的手术经验及效果。 方法：回顾性分析87例行鼻内镜下切除JNA的患者的临床资料。根据肿瘤的部位、大小、侵犯的范围及肿瘤与瞳孔中线的解剖位置关系对JNA进行分类，根据分类选择了3种内镜手术入路方式，并对术后症状、并发症和复发情况进行调查分析。 结果：87例经鼻内镜手术肿瘤切除率100%，经中鼻道入路35例（肿瘤较小，位于鼻腔鼻窦及翼腭窝），经鼻腔外侧壁入路45例（肿瘤侵犯翼腭窝但未超过瞳孔中线），经鼻腔外侧壁+同侧上颌窦前壁入路7例（肿瘤超过瞳孔中线侵及颞下窝或侵犯海绵窦、中颅窝硬脑膜外）。术后患者鼻塞、鼻腔间断流鼻血、头痛头晕、视力下降等症状得到不同程度改善。无手术死亡、颅内感染病例。术后随访6~78个月，复发率3.44%。 结论：经鼻内镜切除JNA手术是治疗JNA的主要手段，术前是否选择行肿瘤营养血管栓塞术可根据肿瘤的位置和分期以及术者的临床操作水平综合考虑；选择合适的鼻内镜入路切除JNA，能够根据人体鼻腔固有解剖空间最大限度的利用鼻内镜设备的优势，以达到切除JNA、减少术中术后并发症、减小复发率、提高预后的目的。.
