Evolution of Superficial Parotidectomy
Typically, a modified Blaire incision is made in front of the ear, within a skin crease. A skin flap is elevated anteriorly to expose the fascia overlying the parotid gland. The facial nerve or one of its branches is found via one or more established methods. During superficial parotidectomy, the superficial portion of the gland is excised directly overlying the facial nerve. It is important to include the entirety of the adenoma, in order to prevent pseudopods from developing into recurrent disease. For this reason, it is vital to identify the facial nerve trunk early in the case, in order to plan the rest of the dissection in a safe manner. The branching pattern of the facial nerve can be highly variable, so a strong knowledge of anatomic variants combined with intraoperative nerve monitoring will aid in safe surgery.
