【摘要】： 目的:對(duì)犬的舌骨上肌群(二腹肌前腹、二腹肌后腹、莖突舌骨肌、下頜舌骨肌和頦舌骨肌)和舌骨下肌群(胸骨舌骨肌、胸骨甲狀肌、甲狀舌骨肌)與喉內(nèi)肌(環(huán)杓側(cè)肌和環(huán)杓后肌)進(jìn)行平靜呼吸、吞咽及發(fā)音狀態(tài)下同步肌電圖的研究,以挑選出與環(huán)杓側(cè)肌、環(huán)杓后肌的肌電特征相似的喉外肌。 方法:13只犬進(jìn)行呼吸、吞咽及發(fā)音時(shí)的同步肌電圖檢查,包括收縮峰電壓、收縮時(shí)程、動(dòng)作電位振幅、動(dòng)作電位時(shí)程,其中5只犬進(jìn)行舌骨上肌群和下肌群同步肌電比較,并分析喉肌肌電與喉功能的關(guān)系。 結(jié)果:(1)平靜呼吸時(shí)二腹肌前腹、二腹肌后腹、莖突舌骨肌、下頜舌骨肌、頦舌骨肌、胸骨舌骨肌、胸骨甲狀肌和環(huán)杓后肌在吸氣相放電,甲狀舌骨肌和環(huán)杓側(cè)肌在呼氣相放電。深呼吸時(shí)諸肌放電強(qiáng)度增加。吸氣時(shí)頦舌骨肌肌電波形、波幅、時(shí)限、強(qiáng)度與環(huán)杓后肌同步且最為相似。呼氣時(shí)甲狀舌骨肌肌電波形、波幅、時(shí)限、強(qiáng)度與環(huán)杓側(cè)肌同步且最為相似。 (2)吞咽時(shí)二腹肌前腹、二腹肌后腹、莖突舌骨肌、下頜舌骨肌、頦舌骨肌、甲狀舌骨肌和環(huán)杓側(cè)肌呈同步性密集型放電。吞咽時(shí)環(huán)杓后肌肌電抑制,吞咽間歇期可見(jiàn)肌電位發(fā)放。胸骨舌骨肌和胸骨甲狀肌無(wú)明顯肌電活動(dòng)。吞咽時(shí)頦舌骨肌、下頜舌骨肌、甲狀舌骨肌肌電波形、波幅、時(shí)限、強(qiáng)度均與環(huán)杓側(cè)肌同步且相似。 (3)發(fā)音時(shí)二腹肌前腹、二腹肌后腹、胸骨舌骨肌、胸骨甲狀肌、甲狀舌骨肌和環(huán)杓側(cè)肌呈同步性密集型放電,環(huán)杓后肌在發(fā)音過(guò)程中持續(xù)放電,動(dòng)作電位出現(xiàn)時(shí)間較遲。莖突舌骨肌和頦舌骨肌無(wú)明顯肌電活動(dòng)。發(fā)音時(shí)下頜舌骨肌和甲狀舌骨肌肌電波形、波幅、時(shí)限、強(qiáng)度均與環(huán)杓側(cè)紀(jì)嗤角蟻嗨啤? 結(jié)論:(1)發(fā)音時(shí)下頜舌骨肌和甲狀舌骨肌肌電波形、波幅、時(shí)限、強(qiáng)度均與環(huán)杓側(cè)肌同步且相似,二者可作為重建聲門內(nèi)收功能的備選肌肉。 (2)吸氣時(shí)頦舌骨肌和胸骨甲狀肌肌電波形、波幅、時(shí)限、強(qiáng)度均與環(huán)杓后肌同步且相似,頦舌骨肌和胸骨甲狀肌可作為重建聲帶外展功能的備選肌肉。 (3)呼氣時(shí)甲狀舌骨肌肌電波形、波幅、時(shí)限、強(qiáng)度均與環(huán)杓側(cè)肌同步且相似,甲狀舌骨肌可作為重建聲門內(nèi)收功能的備選肌肉。 (4)吞咽時(shí)下頜舌骨肌和甲狀舌骨肌肌電波形、波幅、時(shí)限、強(qiáng)度均與環(huán)杓側(cè)肌同步且相似,二者可作為重建聲門內(nèi)收功能的備選肌肉。
[Abstract]:Objective: to study the superior hyoid muscle group (anterior abdomen, posterior abdomen, stylohyoid muscle, mandibular hyoid muscle and geniohyoid muscle) and subhyoid muscle group (sternohyoid muscle, sternum thyroid muscle) in dogs. Thyrohyoid muscle) and internal laryngeal muscle (cricoarytenoid muscle and posterior cricoarytenoid muscle) were studied by synchronous electromyography in swallowing and pronunciation to select the extralaryngeal muscle which is similar to the cricoarytenoid muscle and the posterior cricoarytenoid muscle. Methods Thirteen dogs were examined by synchronous electromyography during breathing, swallowing and pronunciation, including peak voltage, duration of contraction, amplitude of action potential, duration of action potential, and time course of action potential. The synchronous electromyography of superior hyoid muscle group and inferior muscle group were compared in 5 dogs. The relationship between laryngeal myoelectric activity and laryngeal function was analyzed. Results the anterior abdomen, posterior abdomen, stylohyoid muscle, mandibular hyoid muscle, geniohyoid muscle, sternohyoid muscle, sternum thyroid muscle and posterior cricoarytenoid muscle were discharges in inspiratory phase. The myohyoid and cricoarytenoid muscles discharge in the expiratory phase. The intensity of the discharges of the muscles increases during deep breathing. The electric waves, amplitude, duration and intensity of the genioglohyoid muscles are synchronized with and most similar to those of the posterior cricoarytenoid muscles. The amplitude, duration, and intensity of the muscle were in sync with and most similar to those of the cricoarytenoid muscle. 2) during swallowing, the anterior abdomen of the bicentral muscle, the posterior abdomen of the bicentric muscle, the stylohyoid muscle, the mandibular hyoid muscle, the geniohyoid muscle, the thyroid hyoid muscle and the cricoarytenoid muscle showed synchronous and intensive discharges. There was no obvious myoelectric activity in sternohyoid muscle and sternum thyroid muscle. The electromyoelectric activity of geniohyoid muscle, mandibular hyoid muscle and thyrohyoid muscle was similar to that of cricoarytenoid muscle during swallowing. 3) the anterior abdomen of the bicentric muscle, the posterior abdomen of the bicentric muscle, the sternohyoid muscle, the sternum thyroid muscle, the thyrohyoid muscle and the cricoarytenoid muscle showed synchronous and intensive discharge, and the posterior cricoarytenoid muscle continued to discharge during the process of pronunciation. The action potential appeared late. There was no electromyoelectric activity in the styloid hyoid muscle and geniohyoid muscle. The electric wave shape, amplitude, duration, intensity of the mandibular hyoid muscle and the thyroid hyoid muscle were all higher than those of the annular dipper. Conclusion the radio wave shape, amplitude, duration and intensity of the mandibular hyoid muscle and the thyroid hyoid muscle are similar to those of the cricoarytenoid muscle. They can be used as alternative muscles for the reconstruction of glottic adductive function. (2) in inspiratory period, geniohyoid muscle and sternum thyroid muscle were similar to those of posterior cricoarytenoid muscle in wave shape, amplitude, duration and intensity. Geniohyoid muscle and sternum thyroid muscle could be used as alternative muscles for reconstruction of vocal cord abduction function. 3) the myohyoid muscle of thyroid hyoid on exhalation is similar to that of cricoarytenoid muscle in wave shape, amplitude, duration and intensity. The thyroid hyoid muscle can be used as alternative muscle to reconstruct the adductive function of glottis. (4) the electric wave shape, amplitude, duration and intensity of mandibular hyoid muscle and thyroid hyoid muscle were similar to those of cricoarytenoid muscle during swallowing. They could be used as alternative muscles for reconstruction of glottic adductive function.
