下鼻甲部分切除术

2016-03-06 MedSci MedSci原创

下鼻甲部分切除术

  [适应证]

  下鼻甲增生肥大,经其他治疗无效时。

  [手术器械]

  窥鼻器、鼻镊、直血管钳、鼻剪、鼻咬骨钳、中隔剥离器、鼻息肉圈套器。

  [手术准备]

  修剪鼻毛,清洁鼻腔。用1%麻黄素喷布病变的下鼻甲粘膜,根据粘膜收缩程度,决定手术方式。

  [麻醉]

  1%丁卡因表面麻醉,并在下鼻甲粘膜下注射含1%肾上腺素的1%普鲁卡因1~2ml。必要时可用针麻。

  [手术方式]

  按照粘膜肥厚程度,有两种手术方法。若肥厚严重,粘膜不能保留者,作下鼻甲部分切除术;如下鼻甲肥大以骨质增生为主时可作粘膜下部分切除术。

图1 下鼻甲部分切除

  (一)下鼻甲部分切除术 取半卧位或坐位。以鼻甲剪将下鼻甲前端的肥厚粘膜剪开,然后用圈套器套住肥厚的下鼻甲后端,连同已剪开的部分一并切下(图1)。用肾上腺素棉片止血后再以碘仿纱条堵塞鼻腔。

  (二)下鼻甲粘膜下部分切除术 左下鼻甲前端作一小切口,深达下鼻甲骨质,由此插入鼻剪,将下鼻甲下缘剪开形成内外两个侧瓣,并分离下鼻甲骨质,用骨剪剪除增生骨质。并按下鼻甲肥厚程度,将外侧瓣作条状楔形剪除(图2)。止血后将下鼻甲内、外两侧瓣合拢缝合。如无法进行缝合,可直接用凡士林纱布或碘仿纱条堵塞,任其自行愈合(图3)。

  [注意事项]

  下鼻甲切除切忌过多,以免鼻腔过于宽大,形成萎缩性鼻炎,使鼻腔结痂、发臭,增加病人痛苦。如愈合后通气仍不畅,可考虑再次手术。

  [术后处理]

  1.注意出血。术后一般可有少量血性分泌物自前鼻孔渗出,于12~24h后停止。如有鲜血不断流出,或后鼻孔有流血,说明堵塞不够紧,需重新堵塞或加后鼻孔堵塞。

  2.术后24h鼻内可滴石蜡油,以利抽纱条。

  3.术后48h取出鼻腔填纱条,如抽纱条时易出血,纱条可分次逐段抽出,以减少出血。此后每日滴1%麻黄素溶液数次。

  4.不要用力擤涕,以免引起出血。

  5.若粘膜肿胀明显且创面较大,易发生粘连,应每日进行鼻腔检查,必要时用塑料薄膜或明胶海绵置于鼻中隔与鼻甲间,一旦有粘连形成,应将粘连分开后再用塑料薄膜隔开。

  6.抗生素可视情况需要应用。
