In a total laryngectomy the entire larynx is removed and in a partial laryngectomy only a portion is taken out. The laryngectomee breathes through an opening in the neck known as a stoma. This procedure is usually performed in cases of laryngeal cancer. However, many laryngeal cancer cases are now treated only with more conservative surgeries through the mouth or with radiation and/or chemotherapy; laryngectomy is performed when those treatments fail to conserve the larynx or there is sufficient destruction by the cancer that would prevent normal function once it is destroyed. Laryngectomy is also performed on individuals with other types of head and neck cancer or severe swallowing problems. ==Uses== Laryngectomees number about 60,000 in the United States. Perhaps 10,000 laryngeal cancer cases are treated annually, but only about 3,000 people undergo the surgery each year. Because it is a relatively rare cancer and because the post-operative care is complex in achieving a functional result, laryngeal cancer patients should be treated at or at least consult a major federally designated cancer center, where the fields of surgery, radiology, chemotherapy, speech-language pathology are all available. Most laryngeal cancers in the UK are glottic, meaning they start in the vocal cords within the larynx. Glottic cancers tend to be picked up at an early stage, as they cause a hoarse voice very quickly. About 90 out of every 100 people (90%) with T1 glottic cancers are cured with radiotherapy or surgery alone. Of those patients who fail radiotherapy, many will be cured with salvage surgery.〔http://www.cancerhelp.org.uk/type/larynx-cancer/treatment/statistics-and-outlook-for-cancer-of-the-larynx#overall〕 Many surgeons are returning to the use of endoscopic surgery for such early cancers as the voice result is very good and comparable to that of radiation. 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「Laryngectomy」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.
