Abstract

Background

The endoscope-assisted pterygomandibular ligament approach for the resection of parapharyngeal space (PPS) tumors has been reported in a limited number of cases, with insufficiently detailed procedural descriptions.

Purpose

The study purpose was to report clinically relevant outcomes among patients who underwent endoscopy-assisted pterygomandibular ligament resection for PPS tumors.

Study Design, Setting, and Sample

This study was a retrospective case series analyzing patients treated between January 2018 and July 2021 at the Department of Otolaryngology, Second Affiliated Hospital of Wenzhou Medical University. The sample consisted of patients who underwent endoscopy-assisted pterygomandibular ligament resection for PPS tumors. Patients with incomplete medical records or loss of follow-up were excluded.

Main Outcome Variable

The primary outcomes included successful tumor resection, intraoperative blood loss, operation duration, hospital stay, complications, recurrence, and follow-up duration.

Covariates

Demographic characteristics, tumor size, pathology, postoperative pain score were collected and analyzed.

Analyses

Data were summarized using descriptive statistics.

Results

The sample was composed of 9 patients (4 males, 5 females). The operation time ranged from 30 to 240 minutes, with operation blood loss between 5 and 200 mL. The average length of hospital stay was 8.45 days. The average pain score at the first postoperative day was 3.5. No complications, such as infection, bleeding, or nerve damage, were observed. No tumor recurrence was detected over a median follow-up of 53 months (interquartile range: 32.5).

Conclusion

The endoscope-assisted pterygomandibular ligament internal approach appears to be a good strategy for PPS tumor resection.

内镜辅助翼下颌入路切除咽旁肿瘤：一个病例系列。

背景：内窥镜辅助翼下颌韧带入路切除咽旁间隙肿瘤的病例报道有限，但缺乏足够详细的手术描述。目的：研究目的是报告内镜辅助翼下颌韧带切除术治疗咽旁间隙肿瘤患者的临床相关结果。研究设计、环境和样本：本研究是回顾性病例系列研究，分析2018年1月至2021年7月在温州医科大学第二附属医院耳鼻喉科治疗的患者。样本包括接受内镜辅助翼下颌韧带切除术治疗咽旁间隙肿瘤的患者。排除医疗记录不完整或随访缺失的患者。主要结局变量：主要结局包括肿瘤切除成功、术中出血量、手术时间、住院时间、并发症、复发、随访时间。协变量：统计特征、肿瘤大小、病理、术后疼痛评分。分析：采用描述性统计对数据进行汇总。结果：本组共9例患者，男4例，女5例。手术时间30 ~ 240 min，术中出血量5 ~ 200 mL，平均住院时间8.45 d。术后第一天的平均疼痛评分为3.5分。无感染、出血、神经损伤等并发症。中位随访53个月（IQR: 32.5）未发现肿瘤复发。结论：内镜下翼下颌韧带内入路是咽旁间隙肿瘤切除术的一种较好的方法。
