A Case of Malignant Myoepithelioma in Parotid Gland / 대한이비인후과학회지

Myoepithelial cells are a significant component of most types of salivary gland neoplasms, but, pure myoepitheliomas are rare, comprising less than 1% of all salivary gland tumors. Malignant myoepithelioma, or myoepithelial carcinoma, is even more rare. It occurs most frequently in the parotid gland among salivary glands, and is similar to benign myoepitheliomas. The palate is the most common intraoral site of involvement. As far as the treatment of myoepithelial carcinoma is concerned, surgical excision is the mainstay of therapy. The role of radiation therapy and chemotherapy is not yet established. We present a case of malignant myoepithelioma of the left parotid gland in a 67-year-old female patient who was treated with surgical excision followed by adjuvant radiation therapy.

A Case of Direct Hypoglossal-Facial Nerve Side-to-End Anastomosis / 대한이비인후과학회지

When a surgeon fails to save intracranial segement of the facial nerve and can not identify the proximal segment of the facial nerve due to severe adhesion or severe brain stem compression by the tumor, the interpositional graft has no place in helping this patient. Hypoglossal-facial nerve (XII-VII) direct side to end anastomosis is the effective facial reanimation technique used in such a case. This technique compensates for the drawbacks of classical XII-VII anastomosis, and the bothersome strong mass movement and hemiparalysis of the tongue. We recently experienced a case where XII-VII direct side-to-end anastomosis was applied. We report our case with literature review.
