Endoscopy-assisted transoral approach versus external approaches in resection of large benign parapharyngeal space tumors

Abstract

Abstract: PURPOSE: This study compared the clinical effects of endoscopy-assisted transoral approach (EATA) and external approaches (EAs) in the treatment of massive benign parapharyngeal space tumor. METHODS: Sixty-two patients with parapharyngeal space tumors(PSTs) were divided into EATA group and EA group. The perioperative and postoperative clinical data was statistically analysed using SPSS 21.0 software package. RESULTS: All tumors were completely removed. Six patients in EATA group switched to an extraoral approach during surgery. Eight patients in EA group underwent endoscopic surgery. The intraoperative blood loss, total drainage, postoperative pain score, and total length of hospital stay in EATA group were significantly less than those in EA group(P<0.05). The postoperative facial appearance satisfaction score was significantly higher in EATA group than that in EA group (P<0.05). CONCLUSIONS: Use of EATA to remove benign large tumors in the parapharyngeal space can reduce surgical trauma and obtain a better postoperative facial appearance. However, a combination of the two procedures can achieve better surgical results.
