目的 颈外进路切除咽旁间隙肿瘤创伤大 ,并发症多 ,面部或颈部留有疤痕。为了克服上述缺点 ,采用软腭进路切除咽旁间隙肿瘤。方法 患者仰卧 ,头向后伸 ,肩下垫小枕 ,戴维氏开口器撑开口腔。斜行切开软腭粘膜及粘膜下层 ,用血管钳钝性分离肌层达肿瘤包膜 ,沿包膜外用手指分离 ,待瘤体游离后完整摘除。结果 经软腭进路切除咽旁间隙肿瘤 3例 ,均取得了满意的效果。随访 6个月～ 5年无肿瘤复发。结论 经软腭进路切除位置较高达颅底、向鼻咽、口咽腔内隆起的咽旁前间隙良性肿瘤 ,手术经路短 ,最接近肿瘤 ,创伤小 ,损伤血管和神经机会小 ,手术时间短 ,可避免面部或颈部手术疤痕 ,操作简便 ,安全可行。
Objective Extracranial approach to remove the parapharyngeal space tumor trauma, complications, facial or neck scar. In order to overcome the above shortcomings, the use of soft palate approach to remove parapharyngeal space tumor. Methods Patients supine, head back stretch, shoulder pads, Xiaowei opener propped open the mouth. Oblique incision soft palate mucosa and submucosa, vascular pliers blunt dissection of the myometrial tumor capsule, along the envelope with the fingers outside the separation of the tumor to be completely removed. Results Three cases of parapharyngeal space tumor were excised via soft palate. All achieved satisfactory results. Follow-up 6 months to 5 years without tumor recurrence. Conclusions The soft palate approach resection of the higher skull base to the nasopharynx, oropharyngeal uplift of the parapharyngeal space benign tumor, the short operative path, the closest tumor, small trauma, less chance of injury of blood vessels and nerves, operation time Short, to avoid facial or neck surgery scars, easy to operate, safe and feasible.
