ステロイド声帯内注入が有効であった声帯後部癒着の1例

A case of posterior glottic adhesion successfully treated by intracordal steroid injection

はじめに

　化学熱傷とは，さまざまな化学薬品によって引き起こされる熱傷様の皮膚・粘膜障害である。化学的腐食剤による喉頭損傷は，喉頭の化学熱傷ともいわれる。今回，化学熱傷により声帯後部癒着症をきたした症例を経験し，副腎皮質ステロイド（以下，ステロイドと略す）声帯内注射を行い，良好な結果を得たので文献的考察を加えて報告する。

　A 74 year-old female presented with chemical burns caused by ingestion of insecticide and kitchen cleanser for a suicide attempt resulted in posterior glottic adhesion. As initial treatment the scar tissue was removed with CO₂ laser, but re-adhesion occurred within 1 month. In the second operation, scar excision and intracordal injection of triamcinolone acetonide were performed. Re-adhesion has not occurred after the second procedure. Local injection of steroid is effective for preventing a post traumatic scarring.
