Chin implant on a convex chin? (Photo)

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

Achieving better facial balance will come from chin augmentation not a rhinoplasty. Chin augmentation can be done by an implant or sliding genioplasty, each with their own advantages and disadvantages. The labiomental fold is always at risk for slight deepening as it is a fixed structure while the chin point changes underneath it as it moves forward.

 The photographs demonstrate an overly projecting nose, and an under projecting chin. The rhinoplasty procedure can address  shaving down a small nasal dorsal hump, narrowing the bridge, de-projecting the nose and narrowing the tip as necessary. The chin is significantly  recessive, and a chin implant will help significantly with facial balance and proportions, especially in relationship to the overly projecting nose. Chin implants are manufactured in a variety of sizes and shapes, which is best determined at the time of examination and consultation with your surgeon. Chin implants by themselves can be placed through a submental approach under local anesthesia. The rhinoplasty and chin implant combination are both performed under general anesthesia as an outpatient procedure. For many examples and more information about this combination, please see link below

Yes, you are a candidate for a chin implant.  Your chin is quite small.  To achieve facial harmony, you need to balance the lower half of your face.  A chin implant will project the chin forward to balance the face.   You can have a rhinoplasty to refine your nose, which would help with facial harmony.  This can be performed in the same operation as the chin implant.  

If you have a class 1 occlusion you are not a candidate for jaw surgery. Options for increased chin projection are an implant or osseous genioplasty. Each procedure has advantages and disadvantages. Your nose looks pretty good to me.

I think you don't need a rhinoplasty.A chin implant will do the trick and will not expect it to deepen the sulcus. In fact it may efface some of the sulcus.
