Want a genioplasty but worried about chin being too narrow after.

Without an exam your question cannot be answered.  You will need to see an Oral/Maxillofacial surgeon to see if othognathic surgery, genioplasty or using an implant is best for your specific case. It should be noted that patients with severely weak jaws or abnormally functioning jaws may be better treated with other facial surgery (orthognathic surgery), although a chin augmentation may be an option at a later time. These patients should seek the advice of a plastic surgeon to determine which course is right for them. Here is some information to help you make this decision: Candidates for Chin Augmentation - Patients whose chin profiles are weak but have normally functioning jaws are candidates for Chin Augmentation. Many of these candidates have used injectable fillers in the past to strengthen the protrusion of their chins, but are looking for a permanent solution. If you are one of these patients, then you are a likely candidate for chin augmentation

There are two methods in a sliding genioplasty to ensure that not will not appear too narrow from the front view or even wider than it is now. One approach is to place a small anatomic chin implant in front of the chin bone at the time of bony advancement. The other approach is to split the downfractured chin segment in the middle and place an interpositional graft to widen it as it is being brought forward.

it is always important to consider the width of the chin and especially the way it blends into the back part of the jawline. Generally if you have a concern for a narrow chin, it may be that the jawline behind the chin is narrow too.  So one could augment the jawline when you do the genioplasty to blend both together and develop a proper jawline. Otherwise you risk having a chin which is disproportionate to the rest of the jawline. Best to consult a cosmetic Maxillofacial surgeon for full info.
