功能性腮腺切除术治疗腮腺深叶良性肿瘤

目的：探讨保存功能性外科在腮腺深叶肿瘤切除术中的应用及疗效。方法：17例腮腺深叶良性肿瘤患者，其中位于深叶者12例，累及浅深2叶者5例，直径均≤3 cm。采用制备筋膜腺体瓣并预留出将要切除的肿瘤及周围腺体的方法，完整切除腮腺深叶及肿瘤同时保存腮腺浅叶功能。结果：全部患者的手术均顺利完成，创口均Ⅰ期愈合，无涎瘘，外形满意；暂时性面瘫发生2例（11．76％）。17例均获随访，随访时间6～24个月，平均11个月。未见肿瘤复发；面瘫基本消失。结论：应用功能性腮腺切除术治疗腮腺深叶良性肿瘤能有效保存腺体功能，减少面部凹陷畸形及味觉出汗综合征等并发症。

Function-preserving parotidectomy for benign tumors involving the deep parotid lobe

Objective:To evaluate the advantages of function-preserving parotidectomy for benign tumors involving deep parotid lobe. Methods:17 patients with benign tumor involving deep parotid lobe were treated by limited partial parotidectomy.All of the tumors were not more than 3 cm of diameter,12 of them were in the deep lobe and 5 involving both superficial and deep lobes.In the operation fascia glandular flap was made,the tumor with the surrounding gland tissue was thoroughly dissected and the glandular parenchyma was preserved.Results:All the operations were successful and the wounds healed well with symmetrical facial contours.No patient experi-enced salivary fistula.Temporary facial palsy was observed in 2 cases(11.76%).No tumor recurrence was observed.Facial nerve function of all patients completely recovered after a median follow-up of 11 months.Conclusion:Function-preserving parotidectomy for benign tumor involving the parotid deep lobe may improve functional outcomes without compromising local tumor control.
