This study compared $F_{0}$ and the first three formants of eight Korean monophthongs produced by nine transgenders (male to female) to those of eighteen normal adults. Voice analysis was done by Praat (version 4.049). A one-way ANOVA with Tukey HSD post hoc tests were performed to determine statistical differences in $F_{0}$ and formant values obtained from transgenders, and normal male and female subjects. Results indicated that there was no significant difference in $F_{1}$ of /u/, /$\Lambda$/, and /o/, $F_{2}$ of /u/, /$\Lambda$/, and /i/ and $F_{3}$ of /u/ among the 3 groups (transgenders, normal males and normal females). However, in the comparison of transgenders vs. males, a significant difference was observed in $F_{0}$ of /o/, and $F_{2}$ of /i/, /a/, /e/, and /${\ae}$/ and $F_{3}$ of /e/. Furthermore, in the comparison of transgenders vs. females, a significant difference was also observed in $F_{0}$ of all vowels, $F_{1}$ of /i/, /$\alpha$/, /e/, /${\ae}$/, and /i/. $F_{2}$ of /i/, and /${\ae}$/, and $F_{3}$ of /i/, /$\alpha$/, /$\Lambda$/, /e/, /${\ae}$/, /i/, and /o/. Also, perceptual judgment of the transgenders' voice came out somewhat correlated strongly with their $F_{0}$ values but not much with the formant values. It was concluded that the transgenders' acoustic parameters are placed in between those of the normal males and females in. terms of fundamental and formant frequency analyses of vowels. Thus, it was assumed that those differences might stem from the transgenders' original big resonating cavities.

This study compared pitch range, speech rate, pause, intonation type and boundary tones of four sentences produced by five transgenders (male to female) to those of twenty normal adults. Voice analysis was done by Praat (version 4.049). Results indicated that there was a difference in pitch range, speech rate, pause, intonation type and boundary tones among the 3 groups(transgenders, normal males and normal females). Especially, transgenders indicated boundary tones more frequently than normal adults.

This study compared pitch range, total duration of utterances, pause, boundary tones and mean duration of intonation final syllables of 4 sentences produced by 5 transgenders (male to female) to those of twenty normal adults. Voice analysis was performed by Praat (version 4.049). The results showed that there were differences in pitch range, total duration of utterances, pause, boundary tones and mean duration of intonation final syllables among the 3 groups(transgenders, normal males and normal females).

The purpose of this study was to investigate the acoustic characteristics of transgenders' voice. This study obtained acoustic measurements (F0, jitter, shimmer, and NHR) of 45 subjects (15 male adults, 15 female adults, and 15 transgender(male to female)) and compared acoustic measurements of the vowel /a/ produced by 3 groups. The MDVP was used to measure the acoustic parameters. A one-way ANOVA was used for statistical analysis. The results were as follow: Firstly, there was a significant difference among the 3 groups in F0. And F0 of transgenders was higher than that of male group and lower than that of female group. Secondly, there was a significant difference between male and transgender group in jitter and shimmer so that the transgender had a tendency to phonate roughly than male.

The transgender is who has persistent discomfort with his of her sex or sense of inappropriateness in the gender role of that sex. Many transgenders have been undergone trans-sex operations after 1980's. But there were not so much experience of voice surgery for transgenders. Vocal pitch can be elevated by various surgical techniques. Type IV thryoplasty, which one of the cricothyroid approximation methods, increases tension to the vocal folds, thus increasing fundamental frequency and upper pitch range. We treated a transgender (MTF, Male to female) using this technique. Acoustic and aerodynamic measures were obtained both pre- and post-operatively. Clinically significant improvement was achieved in both study; increasing of vocal pitch, widening of pitch range, and improvement of vocal efficiency.

Purpose: Mastectomy is one of the operative procedures of female to male transsexuals. It is aimed to excise all of breast tissues and to reconstruct male chest wall, areola, and nipple. Breast sizes are varied by developmental status and their hormonal therapy. There are several approaches for mastectomy. This study is aimed to suggest appropriate mastectomy methods according to breast size in the female to male transgenders. Methods: We retrospectively analysed 46 patients of female to male transgenders. Breast size was categorized by their inner wear size. In A cup size, mastectomy was done with periareolar approach. In C cup size, inframammary fold approach subcutaneous mastectomy was performed. In B cup size, periareolar approach was used for grade A or B ptosis patient, and inframammary fold approach was choosen for the patient with grade C ptosis. Results: Subcutaneous mastectomy was done through semicircular periareolar approach for 26 patients. There were 2 cases of major complications that should be corrected by hematoma evacuation. Circumareolar approach was used for 5 patients, and a case of nipple-areolar complex necrosis was observed. Two cases of another complications which were irregularity of breast and wound disruption could be corrected. Inframammary fold approach was selected for 15 patients. There was a case of wound disruption, so revision surgery whould be done. Four cases of breast irregularity was corrected spontaneously, and 2 cases of partial necrosis of nipple-areolar complex were corrected with secondary healing. Patient satisfaction score for periareolar, cicumareolar, and inframmammary fold approach were 4.5, 4.2 and 4.1, respectively. Some major and minor complications were observed, but satisfactory results could be secured. Conclusion: Semicircular periareolar incision looked adequate for A cup size patient, circumareolar incision was suitable for B cup size with grade A or B ptosis. In B cup size with grade C ptosis patient and C cup patients, inframammary fold incision looked suitable for optimal results.

Purpose: Transsexualism is considered to be the extreme end of the spectrum of gender identity disorders characterized by, among other things, a pursuit of sex reassignment surgery (SRS). We evaluated psychologic status, health-related quality of life in female-to-male (FTM), male-to-female (MTF) transgender individuals. Methods: We used the Minnesota Multiphasic Personality Inventory, Beck Anxiety Inventory, Beck Depression Inventory, Moudsley obsessive-compulsive Inventory, SCL-90-R, Short-Form 36-Question Health Survey version 2 (SF-36v2). We enrolled 40 transsexual participants. Results: Analysis of quality of life health concepts demonstrated statistically significant (p<0.01) diminished quality of life among the transsexual participants as compared to the Korea male and female population. FTM transgender participants reported more higher hostile, phobic than MTF transgenders. Overall, in all psychologic status examination, Transgender individuals are within normal population boundary. On all category, result is improved post-operatively. Conclusion: Transgender participants reported mental status within normal boundary. SRS improved their quality of life and mental stability.
