title: [Parotidectomy of deep-lobe tumors].
abstract: 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.
