Hi everybody,
here's my Seoul update: after spending a nice evening out in Jongno district with Saskia, we rested and slept off most of our jet lag, and later went to Yeson for the pre-op examination. I have a very favorable impression both of Dr. Kim and of Jessie and of the entire organization.
Turns out there's good news: my "boy mode" voice was measured at around 155 Hz, my "practiced feminine" at 175. There's no tremor – so potentially no Botox in the end –, except for the extremely low range, where it might be present because of disuse. Subglottic pressure and air flow are rather high, though, which may be from years of using breathiness as a feminizing tool.
The length of my vocal cords is right at the borderline between male and female voice boxes (which may be why I never developed an Adam's Apple), however, they are thick and heavy. So he decided on suturing just 1/3 of them, but is going to pay attention to creating a nice tapered suture (more below) in order to enable the vocal folds to "speak" better at higher frequencies (which I need for singing). All in all, Dr. Kim is estimating my speaking F0 to be around 220 Hz post-surgically, which should be almost exactly female average. BTW, Dr. Kim calculates the frequency up from the masculine natural speaking pitch, not from the trained female pronunciation.
The material Dr. Kim is using for the sutures is permanent, but gets embedded in mucosa rather quickly, which is why it's not visible in Jenny's 1-year-post picture.
The "tapered suture" mentioned above is actually one of the key points that set Dr. Kim apart from other glottoplasty surgeons: his first stitch, closest to the old anterior commissure, goes deep and grasps the entire vocal cords and even some of the material underneath and to the sides, to lend maximum stability. The second stitch grasps less and the third one only the medial section of the vocal folds. In this manner he not only ensures a clean contact point in front at the new commissure, but by eliminating a pocket of static air underneath the sutured section that could lead to turbulence at the new commissure also improves sound quality in this way.
Let's see what tomorrow brings. Keep your fingers crossed for me!
