In short. Revision is not a repeat of the first operation. It is planned after three months, it is often harder, and the honest question is what went wrong.
Key points
- Sometimes the best revision is removal rather than exchange.
- An implant that has caused repeated problems, or that the patient no longer wants, can be taken out.
- The contour returns close to the original, and for some patients that is a better result than another attempt at augmentation.
Most chin augmentation patients never need a revision. When one is needed, it is a different operation from the first, planned with different constraints, and it is worth understanding why before agreeing to it. This guide is about the decision, not the technique.
Why revisions happen
The common reasons are a change in projection that the patient did not expect, asymmetry that became visible once swelling settled, displacement of the implant, infection, and dissatisfaction with the shape rather than the size. Less commonly the implant becomes visible or palpable at an edge, or the bone beneath it changes shape over time.
The three-month rule
No responsible revision is planned before about three months. Before that point the tissue is still adapting, apparent asymmetries often resolve, and operating on unsettled tissue can produce a worse result than the one being corrected. The waiting period is not a delay tactic; it is part of the operation.
Is the problem the implant, the plan or the healing?
This is the first question a revision consultation should answer. If the original plan was wrong, exchanging the implant at the same size will not help. If the implant moved, the pocket and fixation need addressing rather than the implant alone. If healing produced asymmetry, the tissue rather than the implant may be the target. Getting this wrong is how patients end up with several operations.
What revision can and cannot fix
Revision can usually correct size, projection, position and asymmetry, and it can remove an infected or displaced implant. It cannot reliably undo changes in the soft tissue envelope, restore sensation that has not returned, or remove a scar. Patients sometimes expect revision to deliver the face they originally imagined; the honest position is that it aims at a specific, definable correction.
Removal is a legitimate outcome
Sometimes the best revision is removal rather than exchange. An implant that has caused repeated problems, or that the patient no longer wants, can be taken out. The contour returns close to the original, and for some patients that is a better result than another attempt at augmentation.
Planning the second operation
A revision plan should state what is being corrected, what will be done differently, what the recovery will be, and what happens if it does not work. It should also be clear about who performs it. There is a reasonable argument that the original surgeon carries responsibility for a revision unless the relationship has broken down, and that is worth raising directly.
Seek care before the planned review if
- The chin becomes red, hot, swollen and painful, or you develop a fever.
- The implant feels as though it has moved, or the chin changes shape suddenly.
- You develop numbness, weakness of the lower lip, or difficulty speaking or swallowing.
Frequently asked questions
How soon can a revision be considered?
Not before about three months. Before that the tissue is still adapting, the apparent problem may resolve on its own, and operating on unsettled tissue risks making the result worse rather than better.
Is revision more difficult than the first operation?
Usually yes. Scar tissue, an existing capsule around the implant and altered anatomy all make the dissection less predictable, and the range of achievable outcomes is often narrower than it was the first time.
Can an implant simply be removed?
Yes, and it is a legitimate outcome rather than a failure. Removal restores something close to the original contour, though the soft tissue does not always return exactly to its pre-operative state.
Risks & Limitations
- Infection, bleeding or a collection around the implant, which may require drainage or removal of the implant.
- Numbness or altered sensation of the chin and lower lip; usually temporary, occasionally permanent.
- Displacement, asymmetry, or a change in the shape of the bone beneath the implant over time.
- Scarring is permanent, whether the incision is placed inside the mouth or in the shadow under the chin.
- Dissatisfaction with the result, which may lead to a second operation; revision is not planned before about three months.
- No outcome can be guaranteed. Results vary with anatomy, healing and time.
When to Seek Care
- Severe pain out of proportion to the procedure, rapidly increasing swelling, or swelling much worse on one side.
- Fever, spreading redness, warmth or discharge from the incision.
- Difficulty breathing or swallowing, or weakness of the lower lip that is getting worse.
- New or worsening numbness weeks after surgery rather than steady improvement.
- An injury to the chin, or an implant that feels as though it has moved.
