The reason I didn't opt for cta is the scar on the neck. In my opinion, it's a dead giveaway for being trans. Had we been in the 1950's then yes, no ne would know about Adam's Apple surgery. These days, it's all over the news and tv programmes! My friend who is cis ( very feminine even for a cis) has a scar on the neck. She was once asked by a guy if her scar was the result of a adam's apple surgery!!!!
Anyway, the other reason I opted for vocal chords shortening is that my preop average comfortable pitch was already at 170 hz so I definitely didn't need CTA.
