• The excision of small parts of the parotid gland is liable to result in damage to the facial nerve, which runs through the substance of the gland. Such damage is hard to avoid if the nerve is not well exposed, and the surgeon has to choose between the danger of facial paralysis and the danger of incomplete performance of the intended extirpation. A good exposure makes it possible to choose between removal of the superficial portion of the gland and total removal of both superficial and deep portions by careful dissection. If there is a malignant tumor in the gland, excision must be total and the nerve must be sacrificed. Nerve grafting, using a section from the greater auricular nerve, was successful in preventing permanent facial paralysis in a case of this kind here described.
