Complications from parotid surgery are well documented and include a scar, facial nerve injury, hematoma, seroma, salivary fistula, and Frey syndrome (gustatory sweating). The facial nerve may be encased in scar tissue, so the traditional method of finding it may have to be augmented by exposing it in the mastoid bone, or more hazardously a peripheral branch traced back. Facial nerve involvement generally suggests a malignant tumor, which may present with pain or paralysis.
