title: Partial Superficial Parotidectomy With Retrograde Dissection of the Facial Nerve for Clinically "Benign" Parotid Tumors.
abstract: BACKGROUND
  To review experience with partial superficial parotidectomy (PSP) and retrograde dissection of the facial nerve as a treatment for benign parotid tumors.
  
  
  METHODS
  Retrospective cohort study of all patients presenting with a suspected benign primary parotid tumor undergoing parotid surgery.
  
  
  RESULTS
  There were 214 cases retrieved. Postoperative facial nerve weakness occurred in 33% of patients; all were temporary. Increased extent of surgical resection (P < .001), deeper tumors (P = .05), and close tumor proximity to the facial nerve (P = .007) significantly correlated with postoperative facial weakness. The surgical margin was clear in 54%; 31% had capsule exposed in at least 1 point, and 13.5% had tumor at the margin. Cases with close proximity of tumor to facial nerve were more likely to have tumor at the margin (P = .034).
  
  
  CONCLUSIONS
  Partial superficial parotidectomy with retrograde dissection is a suitable method for benign appearing parotid tumors.
