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.

A study on 68 patients from 4 to 80 years old ( 37: retrospective, 31: prospective) suffer from pheomoriphic adenomas of parotid gland treated in the Army Hospital No 103 and the Army Academic Institute from 01/1995 -12/1999. Result: There are many types of adenomas of parotid gland in which multi-adenomas of parotid gland occupy high rate: (41.18%) and reduce in simple adenomas of parotid gland (13.24%), hemangioma (11.76%), epiderma (7.35%), cystadenoma and lymphoma (4.41%), lymphangioma 2.94%. Among malignant tumors on parotid gland region, lymph node carcinoma metastasis is most common (30%), followed by thyroid cancer and cylindrom (20%). Malignant tumor rate is 14.7%. The clinical forms on parotid gland region are plentiful and multiform on types, position and nature. There is a significant gap between clinical diagnosis and anatomy diagnosis. Examination of these tumors need to be carefully and should pay attention to clinical quality of each tumor.

Total parotidectomy is indicated when the tumor is originated from a deep lobe of the parotid gland. Because of the facial nerve, the usual sequence of total parotidectomy of a deep lobe tumor is to first perform superficial parotidectomy separately and then to remove the deep lobe. However, it is desirable to remove the parotid gland en-bloc while preserving the facial nerve. We designed a simple procedure that could remove a deep lobe tumor without separating the superficial portion of the parotid gland. This surgical technique is discussed with the present cases.
