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.
