Selective deep lobe parotid surgery for benign tumors.

Conclusions: Deep-lobe tumor parotidectomy decreases the incidence of parotidectomy post-surgical complications, preserves parotid function, and has a good esthetic appearance.

Objective: The existing surgical technique in the parotidectomy of deep-lobe benign tumors can be improved.

Methods: Fourteen surgical operations were performed (2004-2015) for selective deep lobe parotidectomy for patients with primary benign parotid tumors. The patients with deep-lobe benign tumors were operated on with the method of superficial lobe preservation, which included methylene blue staining of the gland and intra-operative facial nerve detection.

Results: During follow-up, no cases of tumor recurrence, permanent facial nerve injury, postparotidectomy depression, or Frey's syndrome was found.
