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.
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.
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.
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.
评估在腮腺深叶肿瘤腮腺切除术中保留浅叶的优势，这些优势包括腮腺切除术后凹陷的发生率更低、各种美学畸形、面神经损伤和味觉出汗综合征的发生率更低。
这项回顾性研究纳入了2001年至2004年住院的114例腮腺良性肿瘤患者，其中13例为腮腺深叶肿瘤患者，101例为腮腺浅叶患者。13例深叶肿瘤患者中有7例采用保留浅叶的方法进行手术。
在中位3年3个月的随访期间，7例接受手术的患者中未发现任何肿瘤复发、永久性面神经损伤、腮腺切除术后凹陷或味觉出汗综合征的病例。仅发生1例面神经下颌缘支麻痹，但在3个月的时间内完全恢复。
在腮腺深叶肿瘤切除术中保留浅叶可降低腮腺切除术并发症的发生率，且对治疗效果无任何影响。此外，术后腮腺功能的保留和美容效果也令患者和外科医生满意。
