Actually it does change it, though not to a large degree. Loss of bone mass throughout the body is a side effect of testosterone reduction, aka HRT for M2Fs, and a propensity for bone mass gain is a side effect of increased testosterone levels, aka HRT for F2Ms. If you don't believe it, look at the study conducted by the Olympic committee that finally allowed post op M2F's to compete as women.
Check your facts before you hypothesize that someone else is wrong please. More importantly, look up all the side effects of any medication you take.
Thank you! I have & admittedly continue to learn daily. It is why we should participate in such forums. To learn. Is it not? Although had assumed we were discussing facial bone structure within the aspect of how long to wait for FFS procedures after beginning HRT? If that is still the case, will stick with my original response. HRT will not change bone structure. HRT alone will not add to zygomatic prominence, reduce brow bossing, open the orbital rims around the eyes, reduce jaw/chin mass structure etc. Heck, it cannot even be counted on for a good nose job. OK, the last one was for humor.
You can wait 12/24/36 months & those bones will remain the same. The layer of soft tissue may thicken over them to soften ones appearance. But again, that is soft tissue.
Long term, details of bone shape(bone remodeling/resorption/replacement see first link) do change over the course of a lifetime regardless of ones own natural progression(aging) or the introduction of HRT. Yes T &/or E do play a role in the skeletal structure over a lifetime. But are we really discussing a time span of 20-30-40 years with relation to FFS?
None of the above means anyone should or should not have FFS. Some are quite happy without ever having it. Have a friend who did not even need to address thyroid cartilage, much less FFS & she did not begin HRT until her 30's. You can see from my photo on the left that thyroid cartilage is an obvious visible marker(aside from others) for me. So we are all a bit unique. However, in all levels of honesty. HRT alone will not change bone structure one has to work with as outlined.

https://www.susans.org/forums/index.php?topic=88481.0Further, while this research by Dr. Maddie Deutsch, Director of Clinical Services at the UCSF Center of Excellence for Transgender Health states to wait the standard 2 years, he is stating the same with regard to bone structure.
"Your eyes and face will begin to develop a more female appearance as the fat under the skin increases and shifts. Because it can take two or more years for these changes to fully develop, you should wait at least that long before considering any drastic facial feminization procedures. What won't change is your bone structure, including your hips, arms, hands, legs and feet."
