I see your motivations being based on logistics (i.e. time windows) and while I see where you're coming from, I ought to provide additional info that you may or may not have considered:
If you do a procedure so close together, then you really won't see your
final results until you are back in the States. This isn't so bad other than the reality that follow-up appointments are
almost always inevitable to correct minor irregularities. While Dr.
Oates is a talented and experienced practitioner, the odds of you having a picture-perfect result are rare.
The reason for this is that the filler being employed (namely
Ellanse) creates
Girth through a mechanism known as neocollagenesis. In small volumes (like when applied to the face with as little as 1 or 2 mL's), it's often a non-issue. However, when injecting 10-25 mL's in the penis, the variation in collagen growth becomes more apparent. An analogy would be your fingernails, how some grow faster than others. With higher volumes of
Ellanse, you'll begin to see minor variations where some areas have more collagen & inflammation than others.
That's why we occasionally read terms like "nodules," "ridges," and "asymmetry," because they are associated with these types of fillers (namely
Ellanse and
PMMA).
This is also why it is important to see an experienced practitioner (like Dr.
Oates, and those linked in the Directory Listing), because they'll keep these irregularities to a minimum via craftsman injection technique -- but the fact remains that no matter how skilled the Doctor or how high quality the filler, there is a degree of uncertainty with respect to your body's response to a foreign object/material/filler.
So that is all to say that if you needed
Revision, you'd have to visit Australia AGAIN, which is no short hike. For this reason, I'm surprised you haven't considered
Avanti Derma or
Androfill for the purposes of
Ellanse. Yes, they don't have the 2-3 week separation allowance (minimum 6 weeks I believe), but if you factor in the likelihood if requiring some kind of touch-up work in the future, this 2-3 week window becomes far less significant in the grand scheme of things.
That is just my advice, in the end Dr.
Oates is the only Doctor I'd recommend in the whole of Australia so you aren't necessarily making a mistake by seeing him, I'm only pointing out that if logistics are your end-goal, you may want to put in perspective the possibility (if not outright inevitability) of future visits (for
Revision and/or additional
Girth).
