Metastatic cSCC and MM to the parotid superficial lobe also involve LNs in the parotid deep lobe and neck in a significant and almost equal number of patients. Parotid deep lobe metastasis from cutaneous malignancies portends a poor prognosis. Therefore, patients with superficial parotid gland metastasis should be considered for management with not only neck dissection and adjuvant therapy but also deep lobe parotidectomy.

Objectives/Hypothesis:To describe the prevalence, clinical course, and outcomes of facial nerve paresis following cochlear implantation and to identify variables associated with poor definitive facial nerve function.Study Design:Retrospective cohort study with systematic literature review.Methods:All patients who underwent cochlear implantation between January 1990 and December 2010 at a single tertiary academic referral center were reviewed. Data including clinical presentation, intraoperative findings, onset, severity, management, and outcomes of all patients who experienced facial nerve paresis following cochlear implantation were recorded.Results:Eight hundred eighty‐eight cochlear implants (282 pediatric, 606 adult) were performed in 768 patients. Eleven patients with postoperative facial nerve paresis were identified. Ten patients (1.1%) developed delayed‐onset paresis and had complete recovery within 6 months of surgery, whereas a single patient (0.1%) demonstrated immediate onset paresis and experienced incomplete return of facial nerve function. Seventeen additional cases were identified in the literature and were summarized.Conclusions:Facial nerve paresis following cochlear implantation is rare. Most cases demonstrate a delayed onset and have complete recovery within months of surgery. Delayed onset facial nerve paresis following cochlear implantation heralds an excellent prognosis, whereas immediate onset facial paresis prognosticates a poorer outcome. In the absence of medical contraindications, corticosteroid therapy should be considered in facial paresis following cochlear implant surgery.
