The purpose of this study was to investigate the feasibility, safety, and efficacy of the resection of parapharyngeal space (PPS) tumors via an endoscopic transoral approach. We reviewed 9 patients who were diagnosed with PPS tumors and who were treated with an endoscopic transoral approach. PPS tumors ranging from 2.5 to 6 cm were removed completely with no complications and excellent recovery (mean inpatient hospital stay: 6.89 days). Pathology was pleomorphic adenoma (n = 7), schwannoma (n = 1) and malignant pleomorphic adenoma (n = 1). For the malignant lesion, the patient underwent postoperative radiotherapy (70 Gy). There was no radiographic evidence of recurrences, with mean follow-up of 11.22 months (range: 3 to 20). We conclude that resection of PPS tumors via an endoscopic transoral approach appears to be feasible, safe, and effective. Potential advantages of this approach include an excellent surgical view, rapid surgical access, less tissue injury, avoidance of external scar, fewer postoperative complications, and less morbidity.
本研究的目的是探讨经口内镜入路切除咽旁间隙（PPS）肿瘤的可行性、安全性及有效性。我们回顾了9例经诊断为PPS肿瘤并接受经口内镜入路治疗的患者。大小在2.5至6厘米之间的PPS肿瘤被完全切除，无并发症且恢复良好（平均住院天数：6.89天）。病理结果为多形性腺瘤（n = 7）、神经鞘瘤（n = 1）和恶性多形性腺瘤（n = 1）。对于恶性病变，患者接受了术后放疗（70 Gy）。在平均11.22个月（范围：3至20个月）的随访中，影像学检查未发现复发迹象。我们得出结论，经口内镜入路切除PPS肿瘤似乎是可行、安全且有效的。该方法的潜在优势包括手术视野极佳、手术入路迅速、组织损伤小、避免外部瘢痕、术后并发症少以及发病率低。
