예송음성센터 김형태원장은 새로운 성대수술 방법인 "성대단축술 및 전유합전진술"을 미국에서 가장 권위있는 미국음성학회인 " Voice Foundation Association"에서 초청 발표하였다.
미국 음성학회인 Voice Foundation은 매년 미국 필라델피아에서 열리는 음성연구학회로서 순수하게 음성만을 연구, 발표하는 유일한 학회로 전세계의 음성전문의들과 음성언어치료사, 음성학자들이 참석하는 권위있는 학회이다. 이번학회는 2007년 5월 29일 부터 6월 3일까지 지속되었다.
이번에 발표된 논문은 성대길이와 성대전유합을 전진시켜 목소리의 톤을 조절할 수 있는 신수술방법으로 예송음성센터에서 최초로 개발되어 발표되는 새로운 성대수술 방법이다.
새로운 시술방법에 대해 이루어진 이번 발표는 많은 음성전문의들로 부터의 호응과 주목을 받았다.

Title : The vocal fold AP shortening and advancement of ant. commissure for feminization of the voice
Abstracts
Objectives : To evaluated results of the modification of vocal fold shortening surgery in patients with androphonia and male-to-female transsexual patients.
Method : Retrospective study of thirty-three patients who underwent the vocal fold shortening between 2004 and 2006 have been done. The modified vocal fold shortening has been performed to patients with androphonia(n=8), androgenital syndrome(n=2), aplastic anemia treated with androgen(n=3) and to male-to-female transexual patients(n=20). The subjective and perceptual assessment, aerodynamic and acoustic assessment, and videostroboscopic assessment were evaluated before and after phonoplasty. All patient was performed voice rehabilitation program after postoperative 2 months.
Results : The average preoperative F0 was 137.3Hz and the mean postoperative F0 achieved was 211.5Hz. Duration of follow up ranged from 6 to 28 months. The average increase in F0 was 74.2 Hz after phonoplasty and voice rehabilitation program. In subjective asssessment, voice feminity was increased. Acoustic assessment presented sPPQ, sAPQ, NHR showed within normal range and subglottic pressure and regularity of mucosal wave of vocal fold maintained in normal range. These fiindings suggest that patients have unartificial voice and could make soft phonation after surgery.
Conclusion : The vocal fold AP shortening and advancement of anterior commissure could be considered an effective method to perform for voice feminization with unartifial voice.
