Abstract:
Background: Parotid gland tumor is a quite common pathology in salivary gland tumor. The exact diagnosis for parotid gland tumors has an important significance because it will help to plan appropriate surgical strategies. Objective: To remark some characteristics of ultrasonographic image of the parotid gland tumors and evaluate the role of ultrasonography in diagnosis of the parotid gland tumors. Subject and methods: A cross-sectional, descriptive study was conducted on 24 patients with parotid gland tumors, operated on at the Department of Plastic and Maxilofacial Surgery of Hospital 103 and the Department of Odonto - Stomatology of Ha Dong General Hospital, Hanoi from January, 2007 to July, 2008. Results: The size of tumors was 2-4cm (58.33%), 21/24 of tumors were in superficial lobe areas. 46.66% of pleomorphic adenomas had a lobulated shape. 2/3 of Warthin\u2019s tumors had an oval shape. 79.17% of the benign lesions were well-defined. 87.5% of all tumors had echogenicity decreased. Almost equal percentages of Warthin\u2019s tumors were echogenicity decreased and structure in heterogeneous. Conclusion: Ultrasonography is a useful method in the diagnosis of the parotid gland tumors, helping to determine clearly the natural basis of some tumors and contributing to early screening for acute parotid gland tumors.
