This study aimed to establish characteristics related to voice and speech through the natural base frequency analysis of esophagus vocalization. In the study, 8 subjects were selected for esophagus vocals, and 10 other subjects were selected for a control group. MDVP(Multi-dimensional Voice Program, Model 4800, USA, 2001), Multi Speech(Model 3700, Kaypantax, USA, 2008) were used as experiment equipment. The speech samples selected for evaluation were vowels and sentences (both declarative and interrogative). For acoustic analysis, the intonation form of fo, jitter, energy, shimmer, HNR, and intonation patterns of the speech sample were measured. The results were as follows: First, the natural intrinsic frequency of extended vowels in the esophagus vocal group was lower than the frequency in the normal vocal group. In particular, the intrinsic frequency difference for high vowel /i/ was much greater than the frequency difference for low vowel /a/. Second, the jitter values of the esophagus vocal group were higher than the control group. In particular, there was a large difference between the jitter values for /a/ and /i/, with the jitter values being highest for /i/. Third, there was no significant difference in vocal strength between the esophagus vocal patient group and the control group. Fourth, the shimmer values of the voices in the esophagus vocal group were higher than shimmer values in the control group. In particular, there was a large difference in shimmer values for low vowel /a/. Fifth, the HNR values of the esophagus vocal group were showed significantly lower than the control group. In particular, the largest difference in HNR values between the two groups was for high vowel /i/. Sixth, the pitch contours of interrogative and declarative sentences of the esophagus vocal patient group showed a different form or only had with small differences compared to the pitch contours of the normal vocal group, thus presenting an inconsistent pattern.

Total laryngectomy is the most useful procedure tor advanced laryngopharyngeal cancer, but it remains the major problem such as loss of voice. Voice restoration is essential for every patients who undergo a total laryngectomy. Ideal voice rehabilitation methods can resolve three factors. First, every laryngectomee can produce voice sufficient for communication, second every patient should be allowed to use both hands freely during phonation, and last, the voice restoration methods should be easy and safe without complication during and after treatment. Among various voice rehabilitation procedures during or after total laryngectomy, it can be divided electronic and pneumatic methods. In pneumatic methods, there are also divided both pulmonary air and non-pulmonary air methods. The non-pulmonary air methods include esophageal speech, buccal speech, and pharyngeal speech. Pulmonary air methods are divided into surgical and non-surgical such as pneumatic speech aid. In the surgical methods, there are neoglottic operation, tracheopharyngeal shunt, and tracheopharyngeal shunt operations. Recently, tracheoesophageal shunt with or without prosthesis are being recognized the most effective method. Blom-Singer low pressure prosthesis, Panje button, and Provox are well known types of prosthesis in the tracheoesophageal shunt operation. Amatsu method is a kind of famous tracheoesophageal shunt method without using prosthesis. Authors tried to review the published articles for evaluation of effectiveness and problems of tracheoesophageal shunt operation with or without prosthesis. In conclusion, indwelling type of prosthesis and pharyngeal myotomy and plexus neurectomy are recommended for higher success rate during tracheoesophageal puncture procedure. More over, Amatsu method is also one of the recommended voice rehabilitation procedure during total laryngectomy. In this situation, pharyngeal myotomy and plexus neurectomy may be helpful for better fluent communication.

후두 악성종양의 치료로서 후두전적출술을 시행하는 경우 환자는 의사 전달수단인 언어의 장애를 동반하게 된다. 후두전적출술후 언어장애를 해결하기 위해 여러종류의 음성재활법이 제시되어 만족할 만한 결과를 얻고 있으나 그중 식도발성은 대부분의 학자들이 인정하는 가장 추천할 만한 방법이지만 시간이 걸리고 배우기가 어려워 환자들이 쉽게 단념할 수 있다는 단점이 있다. 저자들은 후두전적출술을 받은 10명의 환자에서 인두식도분절을 fluoroscopy로 관찰하여 다음과 같은 결과를 얻었기에 보고하는 바이다. 1) 식도발성을 잘하는 예에서는 pseudoglottis의 전후길이가 좌우길이보다 길었고 식도발성을 못하는 9례에서는 좌우길이가 전후길이보다 크거나 길었다. 2) 식도발성을 못하는 9례중 7례에서 인두식도 분절을 관찰할 수 있었다. 3) 인두식도분절에서 pseudoglottis의 모양이 식도발성을 잘하는 예에서는 정상성대와 유사하게 나타났다. 4) 식도발성을 잘하는 예에서는 pseudoglottis의 위치가 윤상인두괄약근 상방 2cm부위에서 관찰되었으며 식도발성을 못하는 9례중 6례에서는 pseudoglottis의 위치가 윤상인두괄약근 위치였으며 2례에서는 pseudoglottis가 각각 윤상인두괄약근상방 1cm, 1.5cm에 있었다.
