Any options to make my chin not stick out from my profile view when smiling? (photos)

It is a tempting and easy fix just merely shave the chin edges with a
burr, very accessible technically and very little training is needed.
However under no circustances I do support or recommend (neither practice,
obviously) the chin "shaving" with a burr, which is what you seem to
have interest in. Chin burring is easy, needs little or no planning, can be
done with a submental incision and requires very little skills or
calculations, however has major and unacceptable downsides:
-flattens
and deletes the natural chin prominence, its dome, and commonly makes
the labiomental fold disappear or close to be deleted
-forces to
total dettachment of mentalis rhape, otherwise full countur to burr the
chin is unfeasible, leading to a flaccid, droopy, hollow and unestable
chin, which commonly ends in droopy chin, double chin or jowls and
double chin increase or formation, requiring reoperation
-makes impossible versatile manuvers like horizontal width reduction and other multidimensional modifications
I understand you want a reduction in your chin, which is a very
common request in the office among osseus genioplasty patients, like is my
case and experience after decades performing this procedure. Viewing
your images your diagnosis is of an oversized chin with this
disaggregated technical assessment:
-very slight anterior excess / prominence
-moderate vertical excess
-significant horizontal width excess and too masculine square shape
Should you be my patient I'd have you know the former conditions and suggested
a multidimensional osseous reduction genioplasty, consisting in a
series of precision cuts on the chin bone based on a meticulous preop
radiologic planning as per your cephalometry. The plan would be:
-oblique
up-down + rear-forwad osteotomy with the preop planned angle on the
prominent chin with a subsequent resection of a same-angle slice of bone
as per preop calculations; this would provide both anterior
deprojection/reduction and vertical shortening in the agreed amount
-the
horizontal width excess and the square look is addressed cutting a chip
of cubic bone in the very right center of the split chin portion, as
per preop planning
-final assemble is made with steel wiring so
that stabilization and mounting the puzzle is achieved, creating a three
dimensional reducion genioplasty effect (many cases personally done
like this) in the preoperatively agreed and planned grade, still
preserving the round shape and the nicely shaped chin prominence, making
a good facial balance, without chin droopiness, without double chin or
jowls formatio/increase, thanks to NOT DETTACHING the mentalis muscles
and the soft chin apart from the osseous chin, this is a FUNDAMENTAL
care that HAS TO be taken whenever you perform genioplasties, keeping
the tendinuous rhaphe of the mentalis muscles attached to the severed
and split chin bone fragment, not doing so creates chin flaccidity, chin
droopiness, double chin and formation/increase of double chin and
jowls.
If you wish better grounded opinion well lit, focused and
standard images have to be assessed: frontal, both lateral and both
oblique views.
Feel free to request any additional information from me.

Ask your orthodontist if you are a class III malocclusion. Many times a protruding chin is the result of mandibular excess. If so, an osteotomy to reduce the mandible is indicated. If that's not the case, a chin reduction would be the procedure of choice. If you are interested, make sure you discuss these issues with your orthodontist as well as a board certified maxillofacial surgeon. Best of luck!
