Can a Lateral Osteotomy Be Reversed?

From the one photo you posted you appear to have collapse of the upper lateral cartilage. This is a common finding after dorsal hump removal, especially if a prophylactic spreader graft isn't placed.

Fortunately, this is something can can be addressed with revision rhinoplasty surgery. I would suggest you visit with a revision rhinoplasty specialist to examine your nose and give a full assessment of your options.

It is very difficult to reverse a lateral osteotomy.  The osteotomies can be reversed, however, you may end up with more of a flat top or square top nose known as an open roof deformity.  The best option is to perform medial osteotomies to open up the nasal dorsum and place extended spreader grafts in them to improve the width of the inverted V and pinched upper lateral cartilages.  This gives much better definition in dorsal aesthetic lines and reduces that pinched-in appearance.  

You don't give a timeframe for your surgery and your pictures are limited but do suggest some midvault collapse. This can be corrected with spreader grafts and if needed osteotomy and onlay grafts as well. Talk to your surgeon or see someone with extensive revision experience.
