The procedure is most typically performed due to neoplasms (tumors), which are growths of rapidly and abnormally dividing cells. Neoplasms can be benign (non-cancerous) or malignant (cancerous). The majority of parotid gland tumors are benign, however 20% of parotid tumors are found to be malignant.〔 A parotidectomy is typically performed by an otolaryngologist. == Anatomy == There are two parotid glands in the human body. Each parotid gland is located high in the neck just below the ears.〔 A salivary duct by which saliva is secreted (produced and released), runs through the inside of each cheek from each gland. Furthermore, the extratemporal (outside temporal bone) facial nerve and its subsidiaries run through the parotid gland and innervate (supply nerves to) the face. This nerve articulates the muscles for facial expression as well as more specific muscles such as the postauricular muscles, the posterior (back or end) belly of the digastric muscle, and the stylohyoid muscles.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Parotidectomy」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
