Hypothesis
For a 3-cm pleomorphic adenoma confined to the tail of the parotid gland, dissection of the inferior branch of the facial trunk nerve and removal of the inferior half of the superficial lobe are sufficient.
BACKGROUND
In the first half of the 20th century, benign parotid neoplasms were enucleated, irradiated, or both. Complications were common, and recurrence rates for benign pleomorphic adenomas were high (20%-45%), probably because of spillage of tumor cells into the wound.1 A major advance occurred when Janes2 (1940) and Bailey3 (1941) described a supraneural approach to treatment of parotid neoplasms. The facial nerve runs through the parotid gland. It enters posteriorly as a main trunk, and branches within the gland. The cervical and marginal mandibular branches of the lower division are the lowest branches of the facial nerve in the neck. Although the branches share some redundancy, the nerve does not cross over itself. Dissection along one . . . [Full Text of this Article]
