The length of the chin needs to be considered in every patient considering liposuction of the neck, and likewise every patient considering a chin implant needs to be evaluated for excess fat under the chin. A double chin will make a chin look shorter than it really is, and a short chin will make the neck look heavier than it really is.
Most often, one of these problems is more profound than the other. But in many situations there is both a small chin as well as excess neck fat. For these patients these procedures can safely be done concurrently for an even better improvement in their appearance.
