I mentioned moving the lateral orbital rim since you are talking about an osteotomy!! An osteostomy is a bony cut + movement! Plus you said the lateral orbital rim is moved in this "palpebral fissure osteotomy". Of course, once you're talking about osteotomies + moving the orbital rim whereas now you are simply referring to a canthoplasty you will cause a lot of confusion. Canthoplasty = soft tissue manipulation, not an osteotomy (=bony cut+movement)



Yes sure you can get a canthoplasty, but mind you: that's an entirely different procedure than any osteotomy obviously. Plus: you can seriously mess up your eyes with this. A canthopexy can be reversed, in a canthoplasty the canthal tendon is cut! This is permanent, and you thus permanently change the lateral structures of your eyes. No opthalmologic surgeon will be able to ever reverse that anymore. If any surgeon wants to mess up your young eyes with a canthoplasty that doesn't sound right to me.



That most people would have similar eyeball sizes is simply incorrect: please post your studies. Again: sure you can get a canthoplasty to lengthen your eyes, but it is not an osteotomy, my previous post was based upon your own reference to an osteotomy in which the lateral orbital rim is moved. A canthoplasty will permanently alter your canthal tendon, no way back anymore.



My point was that there would be no need for this osteotomy if it only produced the same outcome as a lateral canthoplasty which is done routinely for cosmetic reasons - however you are probably right in pointing out that the lateral canthal tendon may not be reattached with this ostetomy and that it is probably premature to speak of an ostetomy as not being a safer and more practical alternative. However, there is no use in speculating about this without further knowledge of the precise aesthetic consequences of the ostetomy v. canthoplasty. My instinct tells me that movement of the lateral orbital rim outward will offer space for the eyeball to set itself further in that direction. This doesn't seem impossible based on what Sinn said about being able to manipulate soft tissue during a mod lf3 to widen the IPD by up to 6mm. But again, no use in speculating at this moment and I may be completely wrong.As for the eyeball size - I have read material on it in the past, I haven't found the studies just now but here's the encyclopaedia brittanica's entry: "The dimensions of the eye are reasonably constant, varying among individuals by only a millimetre or two; the sagittal (vertical) diameter is about 24 millimetres (about one inch) and is usually less than the transverse diameter."Also it's well known that aging eyes appear smaller because they are propped up by less soft tissue behind the eyeball - which is to say that eyeball size is often a function of a set of visual illusions related to eyeball prominence, and there is no reason to suggest that other factors that influence orbital positioning do not contribute to that visual illusion.In any case, this procedure exists, it's "feasible", and it has the ability to elongate the palpebral fissure. That is why I made this thread, and that is how it stands.
