Aesthetics / Re: Opinions on my plan
« Last post by kavan on Today at 10:36:06 AM »The primary culprit behind 'chimp lip' is the linear advancement which is sometimes done for sleep apnea surgery, when someone's bite is right such that both jaws can be advanced equally as ONE COMPLEX to correct the apnea. The term 'linear' advancement refers to along the line of orientation or angle of inclination the maxilla already has relative to a horizontal plane. So, linear advancement implies NO ROTATIONS are done which could be done for advancement to take place over a more aesthetically favorable orientation. For example, when insurance is paying for the surgery, they prioritize the extent the mandible needs to be advanced to correct the airway. But the maxilla has to 'go along with the ride' by the same amount WHETHER OR NOT it would look better when advanced LESS. In general, what a good handful of these 'chimp lip' cases have in common is that the advancement takes place over an UNFAVORABLE inherent orientation of the jaws and no rotations are done to mitigate over advancement. So, what ever amount the lower jaw needs to be advanced to OPEN THE AIRWAY is going to be the same for both jaws and in terms of 'aesthetics', yes, that could resolve to 'over advancement'; the type that is associated with chimp lip. However, linear advancement does not predict that someone will get a chimp lip out of that.If the person just happens to have a favorable rotational orientation to the jaw complex and just happens to need BOTH jaws advanced EQUALLY by the same amount the airway needs to be open, then the aesthetic outcome would tend to be favorable.
In order to PREDICT chimp lip or some uncanny valley result, the ORIENTATION of the maxilla along with a lot of other factors would have to be taken into account. It should be inherently obvious that an actual PLAN you get from the surgeon is a better source of information than people warning you about 'chimp lip'. You don't know what they are taking into account (and they probably don't know either) or if they are in the capacity to predict that your maxillary advancement will result in unfavorable nose changes. For all we know, they could be looking at sleep apnea (insurance) cases and drawing conclusions from that.
Again, what other people say base on cases/people OTHER than YOURS/YOU in terms of unfavorable predictions are neither here nor there as being reliable sources of information directly applicable to you and most CERTAINLY NOT more reliable than a displacement proposal that actually SHOWS you a good approximation of the profile contour change.
You have a displacement proposal right in front of you. Do, you see anything about it that depicts or predicts 'chimp lip' ('monkey muzzle')? Yes___ No___
Is the maxillary advancement the SAME as the lower jaw advancement? Yes___ No___
So, what is it about this plan that looks anything like a 'monkey muzzle' that could substantiate warnings you might have read/heard about?
As to your concern that the surgeon wants to bring your maxilla out further than the nasion, the surgeon is taking into consideration the hooked 'stick-out' you have to the bony nose bridge. So, that resolves to a good aesthetic judgement with aim of giving you a better stream lined 'slope' to the nose. The slope of the nose bridge is somewhat high due to the hooked bony 'stick-out' of the nose bone.
In closing, there is NOTHING in your plan that warrants WORRY about monkey muzzle or unfavorable nose changes providing you OPEN your EYES and LOOK at it.
