I think you need a new surgeon and a re operation to achieve the results you desire. Tertiary rhinoplasty is a difficult operation and the fees are higher...
I agree with the idea of adding fillers and the root of the nose (Apex), above the bump. Further lowering the bump (hump-like) will make your nasal bridge look more curved and the procedure will be more invasive.
Based on your limited photos and your concerns, you appear to have a small profile bump after your nasal bones were rasped. You may have a straight profile restored by adding filler above your bump. In our practice we prefer to use Silikon-1000, an off-label filler for permanent results.
Hope this helps you.
It appears that you have some fullness of the dorsum. After a dorsal hump (bump) has been reduced, there can be slight residual fullness. In the few months following surgery, this may be due to swelling or excessive scar tissue. However, at 8 months following a revision with rasping to reduce the dorsum, this remaining fullness may be due to the underlying cartilage still being to prominent and, if so, will likely not improve with time. You should follow-up with your surgeon for reevaluation to see what the issue is and what options there are to improve it.
