Influence on Sound of Irradiation of Healthy Vocal Cords

放射線照射が声帯に及ぼす影響を知るため, 健常声帯に対する放射線照射の音声への影響を検討した.声門癌ではなく喉頭近傍の癌のため, 平均67.6Gy喉頭に照射された患者を対象とした.放射線照射前, 照射後1, 3, 6, 12, 24ヵ月に音響分析, フォノグラム作製, ストロボスコピー検査での声帯粘膜波動の評価, 最長発声持続時間測定を行った.その結果照射後1ヵ月で各値とも悪化する傾向にあるが, 照射後6～12ヵ月の時点では照射前の状態に戻っていた.このため通常治療線量において健常声帯に対する放射線照射の音声への影響は一時的なものと考えられた.
