Extracapsular Dissection with Facial Nerve Dissection for Benign Parotid Tumors

Abstract

Poster published by the Christiana Care Learning Institute ABSTRACT Technique and outcomes for Extracapsular Dissection with Facial Nerve Dissection for benign parotid tumors are reported. This technique, not previously published, uses standard surgical landmarks to identify and ante-­‐grade dissect the facial nerve trunk. The branches of the facial nerve are dissected up to the anterior extracapsular margin of the tumor, than the tumor is dissected with a thin 1-­‐2 mm layer of parenchyma and fascia around it. This technique is compared to the authors previously reported series on Partial Superficial Parotidectomy with ante-­‐grade facial nerve dissection with a 1-­‐2 cm layer of normal parotid tissue around the tumor. Extracapsular Dissection with Facial nerve Dissection for benign parotid tumors resulted in significantly lower rates of transient facial nerve dysfunction, and sialocele compared to Partial Superficial Parotidectomy without increasing permanent facial nerve dysfunction and thus far recurrence. Longer follow-­‐ up is necessary to more accurately define the recurrence rate of this technique.
