Outcome of surgery for parotid tumours: 5-year experience of a general surgical unit in a teaching hospital

Abstract

Most of the recent reports on the surgical management of parotid gland disorders come from specialist divisions of otolaryngology, head and neck, or faciomaxillary surgery. The aim of the present study was to evaluate the outcome of surgery for parotid tumours in a general surgical unit of a teaching hospital. A prospective clinicopathological study was undertaken over a 5-year period for consecutive patients operated on for parotid gland tumours in the King Saud University Unit of Riyadh Medical Complex. Parameters analyzed were demographic details, clinical presentation, diagnostic work-up, type of surgery, and outcome in terms of early and late morbidity. Thirty seven parotid operations were performed on 36 consecutive patients. All patients presented with parotid gland swelling. Mean age was 51.6 years with a male preponderance. Fine-needle aspiration diagnosed the pathology in 33 out of 37 lesions. Pleomorphic adenoma was the commonest pathology observed in 24 patients (64.9%). Warthin's tumour was more common among male patients and was the only pathology with bilateral involvement. Malignant tumour was found in five patients (13.5%). Superficial conservative parotidectomy was the most frequently performed operation (84%). Overall postoperative morbidity was 13.5%. Transient facial nerve palsy was observed in seven cases (19%). There was no recurrence identified in patients with benign diseases during the mean follow up of 38.5 months. Parotid gland surgery can still be performed in a general surgery unit with comparable outcome. However, the operation should be performed in units with special interest and experience in surgery for parotid gland disorders.
