정상인과 성대용종 환자에서의 공기역학적 검사
Aerodynamic Study in Normal Korean and Patients with Vocal Polyp
초록
최근 음성장애에 관한 관심이 높아지면서 성대질환 내지는 후두질환의 정확한 진단을 위한 발성기능의 측정이 더욱 중요시되기에 이르렀다 이에 본 연구에서는 정상 한국인 남자 81명, 여자 76명과 성대용종 환자 남자 78명, 여자 65명을 대상으로 공기역학적 검사 중 컴퓨터화된 측정기구와 기류저지법으로 최대발성지속시간, 발성기류량, 평균호기류율, 및 성문하압을 연령별 및 성별에 따라 평균치를 측정, 이를 비교 분석하였다. 최대발성지속시간은 정상인 남자가 20.6
Background and Objectives : Recently, many people suffering from voice change visit otolaryngologist. So, it is important to study vocal function in patients with glottic or laryngeal disease. Aerodynamic investigation is valuable information about the efficiency of the larynx in translating air pressure to acoustic signal. The purpose of this study was to investigate the aerodynamic data in patients with vocal polyp, compare this data with that of the normal Korean. Materials and Methods : In aerodynamic study, maximum phonation time, mean air flow rate, phonatory flow volume and subglottal pressure were tested by using Aerophone II voice function analyzer in 157 normal korean and 143 patients with vocal polyp, aged from 20 to 69 years randomly selected. Results and Conclusion : In vocal polyp, maximum phonation time was significantly decreased and mean air How rate was increased. Phonatory flow volume was significantly decreased and subglottic pressure was increased only in female with vocal polyp. These data will be served as basic data of evaluation after treatment and postoperative assessment of the patients with vocal polyp.
