Meta Analysis of Data and Reports on Patient Outcome 

 

1. Mark McGurk published results

(pubmed Extracapsular dissection- minimal resection for benign disease BJOMS Jan 2011)

Type of Surgery

Recurrent tumour at 10y

Permanent  Nerve Injury Temporary Nerve Injury Frey's Syndrome
Total Parotidectomy 1-2% 4-6% 70% 66%
Superficial Paroditectomy 1-2% 1-2% 30% 38%
Extra Capsular Dissection (ECD) 1-2% 1-2% 10% 0%

  

Published met-analysis for ECD shows that with ECD there is reduced risk of facial nerve injury, reduced incidence of complications, elimination of Frey' s syndrome and shorter hospital stays. Risk of reoccurrence is reduced (1% - 2%  at ten-year follow up)
