Clinical and statistical study of salivary gland adenoma

The authors studied 100 patients with salivary gland adenomas for a period of ten years (from 1989 to 1999). Different types of adenomas regarding their glandular localization, clinical presentation, the age and the sex of the patients were studied. Different diagnostic methods were applied: medical history, clinical examination, sonography, scintigraphy, tomodensitometry, sialography, express morphological diagnosis and permanent histological preparation. All patients were treated surgically: in 61% lateral parotidectomy was performed, in 1.4% - conservative parotidectomy and in 24% - enucleation. The authors report about 7.75% recurrence of pleomorphic adenoma and 6% malignization, mainly in the recurrences of the pleomorphic adenoma. In 22 of the patients a postoperative paresis was observed, in 18 of them it was transitory and gradually disappeared after 8 to 9 months. Auriculotemporal syndrome was observed in 4 of the patients.
