Getting deep plane facelift & neck lift, do I also need a chin implant? (Photos)

I would agree with your surgeon that a chin implant would help with overall facial balance. The procedure will not drastically change your appearance but a nice look to your jawline.

For unique cases where a variety of modalities could be used to treat the condition, I would suggest an in-person or virtual consultation to develop a custom and effective treatment plan. It is difficult to precisely define the best option without collecting the same information. I suggest reaching out to an expert for a consultation with surgical and non-surgical methods to get a comprehensive option. Best, Dr. Emer.

It appears that small chin implant would further enhance your neck angle and overall balance. Hope that this helps.

First of all, make sure that you have the necessary comfort level with the Surgeon that you are choosing. However, based on the photos, a small chin implant should enhance our result and is a good idea if performed correctly. I recommend that you discuss this again with your Surgeon if you have any doubts.

I understand your concerns about the recommended chin implant. A customized chin implant designed specifically for your needs can indeed enhance your overall look and improve your jawline.
Unlike standard "small, medium, or large" implants, a custom implant ensures a precise fit and addresses your unique facial features, providing a more natural and harmonious result.You can expect a balanced and aesthetically pleasing outcome by combining the facelift and neck lift with a custom chin implant. The custom implant will complement the other procedures, enhancing the contour of your jawline and harmonizing your facial features.
If you decide not to proceed with the chin implant, it may not necessarily diminish the final results of the facelift and neck lift. However, incorporating the customized chin implant into the overall treatment plan can maximize the potential of the surgery and achieve a more comprehensive and refined transformation.

Your photographs are rather limited, but it does appear that you have a recessive chin, therefore, a chin implant would be of some benefit to give you a better jawline results from your face and neck lift procedure.
