Hey guys. I was wondering why I had a deeper nasolabial fold on one side, and thought perhaps it was just due to my cheekbone being recessed on one side.
A smaller zygo on one side looks to be part of it.
However, it is also caused by a deep canine fossa on one side.
This is the canine fossa:
Here are a range of canine fossa, from shallow (left) to deep (right):
To see if one of my canine fossa were deeper, I took side screenshots of my cone beam CT and overlay them.
Flicking between them I could see the cheekbone was recessed and the canine fossa was deeper on the side with the more visible nasolabial fold:
Obviously for many people nasolabial folds are also caused by recessed maxilla. However, many people also have a recessed midface and relatively 'normal' lower maxillas.
This means the "solution" would be to augment the midface. You'd need custom implant/s that fill in the canine fossa, and small custom ones to augment cheekbones in a masculine/conservative way. Depending on the size of the implant, you may be able to do custom infraorbitals which extend down into the midface to fill the canine fossa. However, I know Eppley usually splits the lower midface and the eye area into two different regions and will put the lower implants in through orally, while the infraorbital goes in through the eye.
Some people also claim that shallow canine fossa correspond with cheek hollowing like this:
While deep fossa correspond with hollowing like this, however in many people they will just create nasolabial folds:
These two types of hollowing can also just be the result of lighting, because you see the two types of hollowing on the same model in different photos.
Several factors including cheekbones, canine fossa, and maxilla recession or recessed upper maxilla can cause nasolabial folds.
It seems depth of the canine fossa is a key part of this for many people, particularly those with relatively good lower maxilla but who have nasolabial folds.
