SURGICAL operation on the parotid gland is most often performed to remove a mixed tumor. The major technical problem involved is related to the proximity of the gland to the facial nerve. The major oncologic problem is the correlation of the histologic picture of the tumor with the ultimate prognosis. This paper will be limited to the technical problems involved in the treatment except when a technic may influence the possibility of subsequent recurrence. The surgical procedure described is not original but is not as well known as is desirable. DEFINITION OF SUBTOTAL PAROTIDECTOMY Total removal of a gland implies that each cell of that organ has been removed. Anatomically, the parotid gland has several prolongations which make total removal difficult. The anatomy of these areas has been best described by Bailey1 and by McCormack and others.2 The parotid gland has extensions (1) along the anterior-inferior wall of
