Accuracy of three-dimensional model printing compared with multislice computed tomography scan as maxillofacial surgical guidance

Abstract

Background: Pleomorphic adenoma considered as the most common benign tumour of the parotid gland. The most effective treatment for this lesion is a surgical excision. Superficial parotidectomy is considered to be gold standard for benign tumours localised in superficial parotid lobe but has higher complication rate. Objective: The objective of this study was to analyse surgical outcome of superficial parotidectomy on the treatment of pleomorphic adenoma. Methods: Clinical records on a 3-year period of 15 patients were analysed for surgical outcome characteristics. Findings: On this review, tumour recurrence was found on one patient (6.67%), four patients (26.67%) with auricular numbness, three patients (20%) with facial nerve palsy, one patient (6.67%) with Frey's syndrome. The surgical complication was higher on the tumours with diameter >4 cm. Conclusion: Superficial parotidectomy is favourable as surgical approach on pleomorphic adenoma localised in superficial parotid lobe in certain condition.
