Abstract
Sixteen cases of parotidectomy of benign tumors were performed by means of a short incision with the assistance of endoscopic surgery. The average length of the preauricular and retromandibular incision was 6.9 cm (range, 6.0-8.1 cm). This incision provided safe dissection of the facial nerve trunk and exposed a major part of the gland to direct vision. Identification and separation of the facial nerve branches in peripheral glandular tissue was performed by means of endoscopic surgery instead of wide exposure with a long incision. Because endoscopic surgery provided good illumination and magnification on the monitor, the operation could proceed clearly and sharply in a bloodless field. Therefore, the incidence of facial nerve injury and perioperative morbidity was minimized. In this series, tumors were removed completely, without injury to the facial nerve. Patients were also satisfied with the short and inconspicuous postoperative scars.
