　　[★]

英: larynx (KL,K)
関: 咽頭

解剖

第4～6頚椎の高さにある。約5cm (KL.612) ＜→ C3-C6椎体の高さにある(M.571)

組織

呼吸器の上皮の移行

呼吸上皮
重層扁平上皮：喉頭蓋、声帯遊離縁
声帯以外の粘膜下組織中には喉頭腺が存在。喉頭室部に多い。

リンパ

声帯上：

上喉頭動静脈に沿って舌骨甲状膜を貫通　→　上内頚静脈リンパ節、中内頚静脈リンパ節
喉頭粘膜のリンパ網は、仮声帯、喉頭入口部でよく発達。喉頭蓋基部の小孔を通じて喉頭蓋前間隙のリンパ組織に連絡し、さらに内深頚リンパ節につらなっている。このため声帯上部癌のリンパ節転移率は喉頭癌のうち最も高率(SOTO. 560)

声帯下：

下喉頭動静脈に沿って喉頭前リンパ節・気管リンパ節　→　下内頚静脈リンパ節
喉頭前リンパ節、気管周囲リンパ節につながっている(SOTO. 560)

臨床関連

喉頭異物
喉頭炎症
喉頭非腫瘍性病変

喉頭ポリープ(声帯ポリープ)：声帯縁にに好発する広基性、有茎性の浮腫性腫瘤。声帯前1/3に好発。一側性が多い。表面平滑、色調は声帯と異なる。種々の嗄声を示す。保存療法(沈黙療法)で軽快しなければ手術的に切除。
声帯結節：声帯の前1/3に好発。両側性が多い。女性に多く、声を酷使する職業に多い。幼児・学童では男性に多い。表面の色調は声帯と変わらない。嗄声をしめし、気息性嗄声が主。保存療法(沈黙療法)で軽快しなければ手術的に切除。
