To the best of my knowledge, this is done in pediatric dept on children with very large extent of hyper or hypo telelorism and has about an error range of 3mm where the error range would still be an improvement compared to the excessively far set or close set distance of the eyes. However, this error range would be unacceptable for a cosmetic patient wanting a differential within 3mm either way.
There is a surgery where they can displace part of the LATERAL orbital rim with the lateral canthus still on it as to elongate the palpebral fissure length. However, that would not address a narrow (close set) distance between the eyes and of course, not the orbital box osteotomy.
I've never come across anyone actually having this done for adult cosmetics. Finding out which doctors did it could be done by researching which hospitals have good pediatric departments for cranio-facial deformities and getting the names of the doctors. Hypo or hypertelorism is often associated with other cranio facial deformities. However, I would speculate that a request to any of the doctors who performed this would be returned by a 'no'. A 3mm differential which is about the error range of the surgery would negate a cosmetic request because a cosmetic request would be one where 3mm BEYOND the cosmetic request would be unacceptable. Not to mention the RISKS associated with the surgery.
I tend to think that people DO look into it as a possibility, track down names of cranio-facial docs in pediatric departments who do it and just find out the answer is 'NO'. The pursuit ENDS
That said, do you have any reason to believe that anyone around here who is non-clinically deformed, has actually had the orbital box osteo for the small mm differentials associated with cosmetic complaints?
