안면신경을 침범한 이하선 상피근상피암종에서 유양동절제술을 통한 안면신경의 재건

Epithelial-myoepithelial carcinoma (EMC) is a rare neoplasm of the salivary gland. Although this tumor is a low-grade malignant neoplasm, it might show a highly malignant feature, such as recurrence, cervical metastasis, and distant metastasis. We experienced a 71-year-old man with the palsy of facial nerve caused by the EMC of parotid gland. We performed the total parotidectomy with selective neck dissection and sacrificed the facial nerve with tumor invasion. After simple mastoidectomy for the exposure the proximal facial nerve, the intratemporal facial nerve graft by a sural nerve was performed. His postoperative course was uneventful, and he is currently free from disease 18 months after operation. We report the this case with literature review. (J Clinical Otolaryngol 2006;17:294-299)
