To explore investigate the feasibility of transoral removal of macrosis benign neoplasms in parapharyngeal space.
Sixteen patients with well-defined macrosis benign parapharyngeal space tumors treated by surgery from January 2005 to December 2012 were enrolled in this study. All patients were assessed by CT scan, MRI and CT angiography before surgery. Surgery for the tumors with complete peplos, locating at medial side of carotid and accessible from the oropharynx was completed with the assistance of endoscope, bipolar electrocoagulation or radiofrequency ablation system.
All neoplasms were removed by transoral approach. Tracheotomy was performed in 4 cases. All patients were treated successfully with good postoperative recovery and no significant complications. Postoperative pathological examination showed there were 9 cases of pleomorphic adenoma, 5 cases of neurilemmoma and 2 cases of neurofibroma. By the follows-up of 1-8 years (median 31 months), among 16 cases only one case of neurofibroma recurred.
The transoral removal of macrosis benign neoplasms in parapharyngeal space is safe, manimally invasive and feasible in selected cases, with a high local control rate and a low surgical complication rate.
探讨经口切除咽旁间隙良性坏死性肿瘤的可行性。
选取2005年1月至2012年12月间16例接受手术治疗的、边界清晰的咽旁间隙良性坏死性肿瘤患者纳入本研究。所有患者术前均行CT扫描、MRI及CT血管造影评估。对于包膜完整、位于颈动脉内侧且可经口咽到达的肿瘤，在内镜、双极电凝或射频消融系统辅助下完成手术。
所有肿瘤均经口入路切除。4例行气管切开术。所有患者均成功治疗，术后恢复良好，无明显并发症。术后病理检查显示多形性腺瘤9例，神经鞘瘤5例，神经纤维瘤2例。随访1 - 8年（中位时间31个月），16例中仅1例神经纤维瘤复发。
经口切除咽旁间隙良性坏死性肿瘤在选择合适病例时安全、微创且可行，局部控制率高，手术并发症发生率低。
