Predicting facial nerve invasion by parotid gland carcinoma and outcome of facial reanimation.
We sought to define risk factors for facial nerve involvement in parotid gland carcinoma and assess the outcome of facial nerve reanimation. Medical records were reviewed of 66 patients who underwent surgery for parotid carcinoma in 2000–2007 at a tertiary hospital. Patient and tumor characteristics were compared between patients with and without facial nerve involvement and were analyzed on their influence on functional outcome following reanimation. Facial nerve involvement was verified intraoperatively in 24 patients, of whom 16 underwent reanimation during ablative surgery. Deep lobe invasion was significantly associated with intraoperative finding of facial nerve involvement. Tumors larger than 4 cm and salivary duct carcinoma had an obvious trend for facial nerve involvement. House-Brackmann score at 12 months was 3-4 in most patients. Deep lobe involvement and large tumor size may identify patients at risk of facial nerve involvement. Reanimation is associated with good functional outcome regardless of patient's age.
