Will a short butt crack effect your BBL results?

Dear Dreaming2Long,
it is hard to tell for sure without an examination. If you are considering surgery, I would suggest you consult a board-certified plastic surgeon. Only after a thorough examination, you will get more information and recommendations.

You are in good company with many others who had high hopes for BBL but instead received disappointing results (lumpiness, unevenness, lack of projection in the central and/or lower buttock, post-deflation sagging, etc.) as most of the fat melts away. It is not quite as much the quality of the doctor nor liposuction technique but rather the quality of the procedure that is a large part of the problem. Thus, going back for additional rounds of BBL most often produces the same disappointing results but at another financial loss.

Buttock implants, however, provide a more reliable, predictable, relatively safe, and permanent result, especially for adding projection to the buttock and often smoothing out lumpiness. When considering buttock implants make sure that the surgeon is going to be placing the implants within gluteus muscles , (a.k.a. “intramuscular pocket”), and that they are using anatomically correct, oval-shaped implants, such as Stanton Anatomic ®️ implants.
Please keep in mind that an extremely few number of board-certified plastic surgeons specialize in these buttock implants so be sure to consult with one that is reputable and experienced. Unfortunately you may have to travel long and far away from home to find this particular surgeon. Glad to help.

NO posted photos to determine if you can be "fixed":??? Best in person or virtual consult with..... Where were your previous surgeries (BBLs) done? Bet a clinic setting and not a private practice??

There are in the end only two variables to determine what cosmetic surgery results are going to look like.
Those two variables are the candidacy of the patient combined with the skill and experience of the surgeon.
You may or may not have been a good candidate and your surgeon may or may not have done a good job.
Without showing before and after pictures we can make an assessment on the outcome of your procedure.
For individuals who had more than one procedure we need to see before and after pictures of each of the procedures to give you a quality assessment.
If you don’t have before and after pictures then ask your surgeon to forward the ones they took.For a proper second opinion consultation I suggest scheduling those as in person consultations with local board-certified plastic surgeons who have experience with this procedure.
For a second opinion consultations patients should come prepared bringing with them all before and after pictures and copies of your operative report. These are all available from your previous surgeons offices if you request them.
Best,
