Hello and thank you for your question. It is hard to determine what the elevation is by just looking at pictures. One possibility may be that the filler migrated or perhaps too much filler was placed or a simple bad filler placement. If this is the situation, depending on the filler that was used, you may be able to get it dissolved.
Another possibility on a worst case scenario, may be that the filler was injected into a vessel that helps with draining fluid from the facial area. This is why it is important that you should consult with an expert to be completely sure of what the situation is, as opposed to just having more filler added.
