包膜外切除术与浅叶切除术治疗腮腺浅叶良性肿瘤的比较研究

Comparison Between Extracapsular Dissection and Superficial Parotidectomy for the Treatment of Parotid Benign Tumor

目的比较应用包膜外切除术与浅叶切除术治疗腮腺浅叶良性肿瘤的临床疗效。方法收集腮腺浅叶良性结节患者77例,47例行腮腺肿物包膜外切除术,30例行腮腺浅叶切除术。结果浅叶切除组的平均手术时间为(107.3±17.5)min,显著多于包膜外切除组的(71.5±13.5)min(P<0.05)。包膜外切除组的术后涎瘘、暂时性面瘫、口干和Frey's综合征发生率均显著低于浅叶切除组(P<0.05)。包膜外切除组患者暂时性面瘫恢复时间显著短于浅叶切除组(P<0.05)。两组复发率无显著差异。结论对于腮腺浅叶良性小结节患者,腮腺肿物包膜外完整切除术可以高效、安全地切除肿物,减少术后并发症的发生。

Objective To compare the clinical effects of extracapsular dissection and superficial parotidectomy for the treatment of parotid benign tumor. Methods 77 cases of patients with parotid benign tumor were selected, including 47 patients with extracapsular dissection and 30 patients with superficial parotidectomy. Results The average operation time of superficial parotidectomy group was （107.3 ± 17.5） min, significantly more than （71.5 ± 13.5）min of extracapsular dissection group （P〈0.05）. The incidences of postoperative salivary fistula, temporary facial paralysis, mouth dryness and Frey＇s syndrome of extracapsular dissection group were significantly lower than those of superficial parotidectomy group （P 〈0.05）. The recovery time of temporary facial paralysis of extracapsular dissection group was significantly shorter than that of superficial parotidectomy group （P 〈0.05）. No statistical difference was found between two groups in the recurrence rate （P〉0.05）. Conclusions Extracapsular dissection for patients with parotid benign tumor can remove tumor efficiently and safely, and reduce the incidence of postoperative complications.
