Abstract:
Objective:This study investigated the clinical indications, prevention and management of common complications of TORS resection of parapharyngeal space tumors. Methods:The clinical data of 23 patients with parapharyngeal space tumors treated with TORS in the Eye & ENT Hospital of Fudan University from July 2020 to February 2022 were retrospectively analyzed. The surgical methods were divided into simple TORS surgery and TORS combined endoscopic or cervical surgery. The surgical incision can be directly sutured or partially sutured. If the surgical cavity is below the oropharyngeal plane and there is a risk of airway compression, preventive tracheotomy would be performed. No drainage(15 cases) or transnasal negative pressure drainage tube(8 cases) was placed in the operation cavity. In 17 cases, tumors were located between the top of nasopharynx and the lower boundary of oropharynx and these patients underwent simple TORS surgery; one case received combined cervical and endoscopic surgery, as the tumor was located near the skull base with unclear boundary with the deep lobe of parotid gland; five cases underwent combined endoscopic surgery, as the tumor reached the upper part of the nasopharynx or the outer part of the parapharyngeal space. Results:One case underwent emergency hemostasis for postoperative bleeding, and three cases underwent puncture and drainage for postoperative effusion. No complication occurred such as postoperative infection and airway obstruction. The healing grade of surgical incision and surgical cavity in transnasal drainage group was significantly better than that in non-drainage group. Conclusion:TORS operation is a safe and minimally invasive method in treating parapharyngeal space tumors with appropriate size and location. Postoperative effusion is a common complication after TORS. In case that surgical cavity extends to the deep parapharyngeal space or the lower part of the surgical cavity is beneath the surgical incision, the placement of transnasal negative pressure drainage tube after operation can improve postoperative recovery and reduce the incidence of complications such as effusion and infection.
目的:探讨经口机器人手术(TORS)切除咽旁间隙肿瘤的临床适应证及常见并发症的预防和处理。 方法:回顾性分析2020年7月—2022年2月在复旦大学附属眼耳鼻喉科医院行TORS治疗的23例咽旁间隙肿瘤患者的临床资料,手术分为单纯TORS手术和TORS联合内镜或经颈手术。手术切口采取直接缝合或部分缝合。对术腔靠近口咽平面以下有压迫气道风险者行预防性气管切开。根据术腔是否放置引流管分为引流组8例,非引流组15例。23例患者中,17例肿瘤位于鼻咽顶水平及口咽下界水平之间,行单纯TORS手术切除肿瘤;1例肿瘤近颅底且上极和腮腺深叶边界不清行TORS联合经颈及内镜手术;5例瘤体超过鼻咽顶水平行TORS联合内镜手术。 结果:仅1例术后术腔出血即行紧急止血,3例术后术腔积液即行穿刺及扩开排液。患者均未出现术腔感染、气道阻塞等并发症。引流组的切口及术腔愈合明显优于非引流组。 结论:TORS对于大小和部位适合的咽旁间隙肿瘤是一种安全微创的手术方法。术腔积液是TORS术后常见并发症,对于术腔较大且向咽旁深部延伸或术腔的下方低于手术切口下方的肿瘤,术后放置经鼻负压引流管能够促进口咽黏膜切口及术腔的愈合,减少积液感染术腔并发症的发生。.
