title: Parotidectomy: review of treatment and outcomes.
abstract: BACKGROUND
  Parotidectomy is a common surgical procedure performed for a wide array of benign and malignant tumours. The aim of the present study was to review a single-institution experience with parotidectomy over a 10 year period.
  
  
  METHODS
  We retrospectively reviewed 170 patients who had parotidectomy performed. The preoperative investigations, clinicopathological parameters, perioperative morbidity and mortality were assessed.
  
  
  RESULTS
  One hundred and six (62%) of the patients were men. The mean age was 54 years (range 21-80). Indications for parotidectomy included benign tumour (44%), malignant tumour (42%), inflammatory parotid disease (7%) and miscellaneous (5%). The most common benign tumour was pleomorphic adenoma (25%). The most common malignant tumour was metastatic cutaneous squamous cell carcinoma (SCC) (19%). Fine needle aspiration cytology was performed in 83% patients with a sensitivity and specificity for benign tumours of 76% and 97%, respectively. The sensitivity and specificity for malignant tumours was 90% and 99%, respectively. One (0.6%) patient died in the postoperative period. Postoperative complications included wound infection (2.3%), wound haematoma (3.5%) and seroma (6.6%). Six patients (3.5%) developed temporary complete facial paresis, while 33 patients (20%) developed temporary partial facial palsy in the immediate postoperative period. The 2-year disease-free and disease-specific survival for those patients with metastatic cutaneous SCC were 75% and 76%, respectively.
  
  
  CONCLUSIONS
  The most common indications for parotidectomy were pleomorphic adenoma and metastatic cutaneous SCC. Our perioperative morbidity and survival for patients with malignant parotid disease compare favourably with other institutional series.
