頭頸（口咽）癌是美國第六大最常見癌癥，美國每年有將近40000名新增頭頸癌病例。雖然吸煙和飲酒可以增加人們罹患頭頸癌的風(fēng)險，但是感染人乳頭瘤病毒（HPV）帶來的風(fēng)險更大。受到口腔HPV感染的人們罹患頭頸癌的風(fēng)險比普通人群高50倍。目前，將近四分之三頭頸腫瘤患者的檢測呈HPV陽性。有越來越多的新近確診頭頸癌病例是四十多歲和五十多歲的男性。

?

　　自20世紀(jì)90年代初以來，化療和放療一直都是頭頸癌患者的主要治療手段。由于頭頸腫瘤難以到達，并且侵入性手術(shù)會影響器官功能，導(dǎo)致吞咽困難，讓患者被迫使用飼管，所以應(yīng)避免手術(shù)作為頭頸腫瘤患者的一線治療。

機器人手術(shù)沒有切口和疤痕（左），而開放手術(shù)在嘴唇至耳朵之間可見手術(shù)切口（右）

?

　　現(xiàn)在，布列根和婦女醫(yī)院耳鼻喉科的Donald Annino博士和Tom Thomas博士使用最先進的機器人對頭頸癌患者進行治療。作為一種微創(chuàng)手術(shù)，經(jīng)口腔機器人手術(shù)（TORS）利用高清三維放大技術(shù)，機器人和微型儀器通過病人的喉嚨（咽或喉）切除良性腫瘤或癌變組織。Donald Annino博士和Tom Thomas博士從2011年開始對頭頸癌病人實施這一微創(chuàng)手術(shù)，到目前為止，他們已實施了超過45例經(jīng)口腔機器人手術(shù)。
