In order to evaluate the phonatory results obtained with the use of tracheoesophageal prostheses, 38 laryngectomees were examined, 20 of which underwent erigmophonic voice rehabilitation while the other 18 were rehabilitated with the application of a prosthesis. In all cases electroglottography and spectrography of the voice were performed. In the erigmophonic-voice subjects, electroglottography gave a normal glottic wave while spectrography gave a tracing with frequent interruptions, scarce harmonics, altered by the presence of background noises. In the tracheoesophageal prosthesis patients, the electroglottogram showed regular hypopharynx vibratory activity while the spectrogram appeared free of interruptions activity while the spectrogram appeared free of interruptions and presented a uniform distributions and presented a uniform distribution of suffixes. The data obtained demonstrate that better results are obtained with the use of tracheoesophageal prosthesis as it allows the exhaled air to be used in phonation and thus respects respiratory dynamics and pneumophonic synergism. It also makes it possible to achieve a clear, fluent voice. Furthermore, the results obtained with patients with this prosthesis were constantly satisfactory when the long exercises required were performed.
为了评估使用气管食管假体获得的发声效果，对38例喉切除患者进行了检查，其中20例接受了食管发音语音康复，另外18例采用假体进行康复。所有病例均进行了嗓音的电声门图和频谱分析。在食管发音语音的受试者中，电声门图显示声门波正常，而频谱分析显示的描记图有频繁中断、谐波稀少，且受背景噪声影响而改变。在气管食管假体患者中，电声门图显示下咽有规律的振动活动，而频谱图显示无中断活动，后缀呈现均匀分布。所获得的数据表明，使用气管食管假体可获得更好的效果，因为它能使呼出的空气用于发声，从而尊重呼吸动力学和呼吸发声协同作用。它还能使声音清晰、流畅。此外，当进行所需的长期训练时，使用这种假体的患者所获得的结果一直令人满意。
