腮腺深叶肿瘤切除

目的探讨腮腺深叶肿瘤切除保存腮腺浅叶的方法，可使腮腺功能保存，颜面不对称畸形改善，减少面神经损伤和弗雷综合征的发生。方法2001-2004年北京肿瘤医院头颈外科收治腮腺肿瘤114例，其中腮腺浅叶肿瘤101例，深叶肿瘤13例，在深叶肿瘤中7例患者行保存腮腺浅叶的深叶肿瘤切除。结果经过平均3年3个月（20个月至5年）的随访，未见肿瘤复发。7例中仅1例面神经下颌缘支运动减弱，术后3个月面神经恢复正常，其他患者面神经功能正常。所有患者无弗雷综合征发生，面部外观塌陷不明显，腮腺功能正常。结论保存腮腺浅叶的腮腺深叶肿瘤切除可减少面神经损伤和弗雷综合征的发生率，使腮腺的功能和外观得到改善。

Parotidectomy of deep-lobe tumors

OBJECTIVE: To evaluate advantages of the superficial lobe preservation in the parotidectomy of deep-lobe tumors, which include much lower incidence in postparotidectomy depression, variable aesthetic deformities, facial nerve injury and Frey's syndrome. METHODS: This retrospective review included 114 patients with benign parotid gland tumors hospitalized from 2001 to 2004, among which 13 patients with deep-lobe parotid tumors and 101 patients in the superficial lobe of parotid gland. Seven in the 13 patients with deep-lobe tumors were operated with the method of the superficial lobe preservation. RESULTS: During median 3 years and 3 months following-up, no any cases with either tumor recurrence, permanent facial nerve injury, postparotidectomy depression, or Frey's syndrome was found in the 7 operated patients. Only 1 case with the facial nerve marginal mandibular branch palsy occurred, but completely recovered over a 3-month period of time. CONCLUSIONS: Preservation of the superficial lobe for deep-lobe tumors parotidectomy could decrease the incidence of parotidectomy complications without any influence in the treatment effect. Additionally, the parotid function preservation and cosmetic appearance after operation also satisfy both the patients and surgeons.
