The advantages and limitations of the endoscopy-assisted transoral approach (EATA) and external approaches (EAs) in resection of parapharyngeal space tumors (PSTs) remain unclear. In our study, we compared the use of the EATA and the EAs for the resection of large, benign PSTs.
Forty-four patients with PSTs were divided into the EATA and EA groups. The perioperative and postoperative outcomes of the patients were evaluated.
All of the tumors were completely removed. However, the procedure was converted to an open procedure for four patients in the EATA group and for six patients in the EA group who required endoscopic assistance. The intraoperative blood loss, amount and duration of drainage, postoperative pain, total hospital stay, and cosmetic outcomes were superior in the EATA group (P < .05).
Use of the EATA for resection of large, benign PSTs decreased the surgical invasiveness of the procedure and resulted in better aesthetic outcomes. However, use of the combined surgical approach allowed for improved access for the resection of PSTs.
内镜辅助经口入路（EATA）和外部入路（EA）在咽旁间隙肿瘤（PST）切除术中的优势和局限性尚不清楚。在我们的研究中，我们比较了EATA和EA在大型良性PST切除术中的应用。
44例PST患者被分为EATA组和EA组。评估患者的围手术期和术后结果。
所有肿瘤均被完全切除。然而，EATA组有4例患者以及EA组有6例需要内镜辅助的患者手术转为开放手术。EATA组的术中出血量、引流量和引流持续时间、术后疼痛、总住院时间和美容效果更优（P < 0.05）。
使用EATA切除大型良性PST可降低手术侵袭性并产生更好的美学效果。然而，联合手术入路可改善PST切除的手术视野。
