【摘要】：目的 探討聲帶息肉及聲帶小結(jié)患者發(fā)音時(shí)最小聲門面積(Minimum Glottal Area, MGA)與聲學(xué)指標(biāo)(基頻微擾、振幅微擾、諧噪比)及空氣動(dòng)力學(xué)指標(biāo)(平均氣流率、聲門阻力、聲門下壓力)的相關(guān)性。 方法 對(duì)50例正常人(女30例,男20例),35例聲帶息肉患者及36例聲帶小結(jié)患者進(jìn)行檢查,以頻閃喉鏡從口腔插入,檢查聲帶,囑患者發(fā)“[i：]”音,并記錄檢查視頻,應(yīng)用配套KIPS軟件計(jì)算聲門發(fā)音時(shí)最小聲門面積(正常組僅查此項(xiàng))；采用CSL3700(Computerized Speech Lab3700),評(píng)估基頻微擾(Jitter)、振幅微擾(Shimmer)、諧噪比(harmony to noise ratio, HNR);以空氣動(dòng)力學(xué)嗓音功能分析儀(Aerophone Ⅱ Voice Function Analyzer)及配套軟件測(cè)得平均氣流率(mean airflow rate, MFR)、聲門阻力(glottal resistance, Rg)、聲門下壓力(subglottal pressure, SGP),以發(fā)音時(shí)最小聲門面積與這些指標(biāo)進(jìn)行比較、分析。用30例正常女性發(fā)音時(shí)最小聲門面積與聲帶小結(jié)組進(jìn)行配對(duì)資料t檢驗(yàn),檢驗(yàn)標(biāo)準(zhǔn)為a=0.05；用全部50例正常人的發(fā)音時(shí)最小聲門面積與聲帶息肉患者進(jìn)行配對(duì)資料t檢驗(yàn),檢驗(yàn)標(biāo)準(zhǔn)為a=0.05。采用pearson相關(guān)分析檢驗(yàn)發(fā)音時(shí)最小聲門面積與患者發(fā)音時(shí)空氣動(dòng)力學(xué)指標(biāo)及聲學(xué)指標(biāo)之間的相關(guān)性,P0.05有統(tǒng)計(jì)學(xué)意義。 結(jié)果 正常女性發(fā)音時(shí)最小聲門面積與聲帶小結(jié)比較差別有統(tǒng)計(jì)學(xué)意義(P0.05)；所有正常人發(fā)音時(shí)最小聲門面積與聲帶息肉患者比較差別有統(tǒng)計(jì)學(xué)意義(P0.05)�；颊呓M以發(fā)音時(shí)最小聲門面積與其他指標(biāo)進(jìn)行一一比較,僅聲帶小結(jié)患者的發(fā)音時(shí)最小聲門面積與聲門下壓力無(wú)明顯相關(guān)性(r=0.060,P0.05)；聲帶息肉組發(fā)音時(shí)最小聲門面積與基頻微擾(r=0.968,P0.05)振幅微擾(r=0.981,P0.05)及平均氣流率(r=0.995,P0.05)呈正相關(guān)關(guān)系,與聲門阻力(r=-0.998,P0.05)及諧噪比(r=-0.996,P0.05)呈負(fù)相關(guān)關(guān)系,發(fā)音時(shí)最小聲門面積與其他指標(biāo)關(guān)系在聲帶小結(jié)組與息肉組相同(r=0.990,P0.05；r=0.996,P0.05；r=0.996,P0.05；r=-0.992,P0.05；r=-0.992,P0.05),聲帶息肉組發(fā)音時(shí)最小聲門面積與聲門下壓力呈正相關(guān)關(guān)系(r=0.997,P0.05)。 結(jié)論 聲帶息肉及聲帶小結(jié)患者發(fā)音時(shí)最小聲門面積較正常人增大,聲門閉合不良造成基頻微擾、振幅微擾、平均氣流率及噪音成分增加,是造成聲音嘶啞的一個(gè)重要原因。發(fā)音時(shí)最小聲門面積與基頻微擾、振幅微擾、諧噪比、聲門下壓力(聲帶小結(jié)除外)、平均氣流率及聲門阻力有明顯的相關(guān)性,發(fā)音時(shí)最小聲門面積也可以作為評(píng)判聲帶息肉及聲帶小結(jié)病變嚴(yán)重程度的一項(xiàng)指標(biāo)。用頻閃喉鏡并配合kips軟件進(jìn)行發(fā)音時(shí)最小聲門面積測(cè)量是簡(jiǎn)單易行的辦法。
[Abstract]:Objective to investigate the minimum glottic area (Minimum Glottal Area, MGA) and acoustic indices (fundamental frequency perturbation, amplitude perturbation, harmonic noise ratio) and aerodynamics (mean airflow rate, glottic resistance) in patients with vocal cord polyps and vocal nodules. Subglottic pressure). Methods 35 patients with vocal cord polyps and 36 patients with vocal cord nodules were examined in 50 normal subjects (30 women and 20 men). The vocal cords were inserted from the mouth by stroboscopic laryngoscope, and the patients were asked to make the "[I:]" sound. The video was recorded and the minimum glottic area was calculated by using the matching KIPS software. Evaluation of fundamental Frequency perturbation (Jitter), amplitude perturbation (Shimmer), Harmonic noise ratio (harmony to noise ratio, HNR);) by using CSL3700 (Computerized Speech Lab3700, the average airflow rate of (mean airflow rate, MFR), glottic resistance (glottal resistance, Rg), was measured by Aerophone 鈪，
