초록

목적 : 후두암에서 방사선 치료는 음성을 보존할 수 있기 때문에 조기 성문암의 일차적인 치료법으로 사용된다. 이에 T1a 병기 성문암에서 방사선 치료가 환자의 음성에 미치는 영향을 알아보고자 하였다. 대상 및 방법 : 조기 성문암(T1a)으로 진단 받고 방사선 치료를 받은 후 최소 1년이 지난 17명의 남자 환자들을 대상으로 객관적인 음성검사들(음향분석, 공기역학검사, 후두 스트로보스코피)을 이용하여 음성을 평가하였고, 이것을 성별과 연령을 맞춘 정상 대조군과 비교하였다. 음향분석으로는 평균 기본주파수(Fo), jitter, shimmer, 잡음 대 조화음 비율(Noise to Harmonics Ratio)을 측정하였다. 공기역학적 검사로는 최대발성지속시간, 평균호기류율, 음강도, 성문하압, 성문저항, 성문효율, 성문력을 측정하였다. 결과 : 방사선 치료를 받은 환자에서 음향분석의 shimmer만이 통계학적으로 의의 있게 높았다. 그 외 다른 검사나 공기역학검사에서는 두 군 간에 통계학적인 유의성이 없었다. 결론 : 본 연구에서는 단지 shimmer만이 방사선 치료 환자군에서 높았기 때문에 T1a 병기 성문암에서의 방사선치료는 음성의 질에 큰 영향을 미치지 않은 것으로 사료된다.

Purpose : To evaluate the voices of irradiated patients with early glottic carcinoma and to compare these with the voices of healthy volunteers. Materials and Methods : The voice samples (sustained vowel) of seventeen male patients who had been irradiated for T1a glottic squamous carcinoma at least 1 year prior to the study were analyzed with objective voice analyzer (acoustic voice analysis, aerodynamic test, and videostroboscopic analysis) and compared with those of a normal group of twenty age- and sex-matched volunteers. Average fundamental frequency, jitter, shimmer, and noise-to-harmonic ratio were obtained for acoustic voice analysis. Maximal phonation time, mean flow rate, intensity, subglottic pressure, glottal resistance, glottal efficiency, and glottal power were obtained for aerodynamic test. Results : The irradiated group presented higher values of shimmer in acoustic voice analysis. There was no significant difference between two groups in other parameters. Conclusion : In this study all the objective voice parameters except shimmer were no4 significantly different between the irradiated group and the control group. These results suggest that the voice quality is minimally affected by radiation therapy for 71 a glottic carcinoma.
