Superficial parotidectomy as first choice for parotid tumours.
Parotid neoplasms represent 3% of all head and neck tumours, and most are benign. Malignant tumours account for 14-25% of cases. Surgery is the treatment of choice, with options ranging from simple enucleation to radical parotidectomy. Sixteen patients presented with a history of a painless parotid lump. Diagnosis was achieved by ultrasound scan and MRI. Fifteen superficial parotidectomies and 1 nerve-sparing total parotidectomy were carried out. At histology, 10 pleomorphic adenomas, 4 Warthin's tumours, 1 lymphoepithelial cyst and 1 sebaceous adenocarcinoma were detected. In the single case of carcinoma, the 6 peri-glandular lymph nodes included in the specimen were metastasis-free. In 3 patients (20%) a transient paresis of the facial nerve was noted. The capsule appeared breached in only 1 case of pleomorphic adenoma. Four patients (26%) were diagnosed as suffering from Frey's syndrome. A salivary fistula was recorded in 2 patients (13%). During follow-up ranging from 3 to 96 months no tumour recurrence was recorded. Superficial parotidectomy seems to be the best choice of treatment for benign parotid tumours, since it allows complete excision of the tumour with sparing of the facial nerve. A radical procedure is, however, needed if malignancy is confirmed at frozen section.
