Cartilage graft on nose tip is bulky and uneven after revision rhinoplasty. Can it be removed and how long do I need to wait?

I am sorry to hear that you having a difficult time. Tip grafts are a great tool that can be used to modify the shape, projection, and rotation of the nasal tip. However, tip grafts also strengthen the nasal framework and can exert pressure on the overlying skin. When the skin is thin, visible edges and irregularities in the graft may become noticeable. If the graft projects too high above the other cartilages it can look odd and stiff, and is known as a "tombstone" deformity.  It is usually safe to remove the graft, however it is rarely necessary. The graft should be beveled to have soft smooth edges at all the contact points with the skin. The height and width of the graft can be modified also if needed. Finally, it is very helpful to cover the graft with a small piece of your own tissue (muscle or fascia) to provide a bit of cushion between the graft and your skin. I suggest that you return to your surgeon to politely discuss your concerns and find a suitable solution. My best.

Yes, the tip graft can generally be removed. That being said, there was probably a reason the surgeon placed it there in the first place. If it is removed with nothing else done, you may have an undesired outcome. I would either consult with your initial surgeon or find another surgeon who can evaluate you in person and discuss your options in depth. Best of luck
