ABSTRACT
A new biopsy method for the study of the parotid gland is proposed. 60 patients with enlarged parotid gland were studied and samples in 44 of them were obtained for investigation. There was a hematoma in the tapping area of two patients but both recoved. This new-method implies a simple procedure, without serious complications that will facilitate the development of clinical studies and further investigation of the parotid gland.
