I was wondering what the average cost of a rhinoplasty and chin implant combination would be? (Photo)

Fees for rhinoplasty and chin augmentation including the fee for the implant, surgeon, surgical facility, anesthesia, and post operative care will depend on the city and surgeon. With that said it's best to set up a few consultations with different surgeons and make an informed decision based on their experience and speciality in the field. View their before and after photos to see what the outcome could potentially be.

I made a computer morph of your nose, and an animation of the morph, to show the changes that are possible for your nose in truly expert hands.I brought the tip of your nose back closer to your face. When that happens, as you'll see best in the animation, the lip comes back a little, too. A projecting nose pulls the top of the upper lip up onto the bottom of the nose.I also lowered the bump on the bridge, and actually, I raised the tip a bit, too, but it's hard to see: when you lower a bump and deproject a tip, it makes the nose *look* longer, so we raise the tip to compensate.Your chin isn't really all that weak, and besides, your chin is strong in its *vertical* height, so we don't want it too far forward: it might look to strong -- and besides, when the nose comes back toward the face, the chin looks stronger anyway. Perhaps the smallest chin implant, but no more.
You should understand that the changes I demonstrated in the morph require advanced techniques, techniques that most plastic surgeons cannot handle.  Be sure to read the section in the "Web reference" link on how to stay out of trouble while searching for a rhinoplasty surgeon, and how to tell whether your primary surgeon should be performing your revision. You should only have surgery if you are able to make yourself very confident in your surgeon's skills.
I'd love to hear what you think of the morph. Did it seem to address your main concerns? Would you like me to draw in the chin?
Your nose is also a good example of why computer imaging is mandatory in rhinoplasty. You need to know exactly what the surgeon is planning to accomplish -- what features he thinks he can change, and by how much he thinks he can change them. When you see his goals, you'll know whether he has an eye for a beautiful nose, and whether he shares your opinion of what constitutes a beautiful nose. You'll also know whether the changes he proposes are enough to be meaningful to you, and whether he understands your wishes enough to address all of your priorities. But remember, you're not hiring him for his skills with the computer. The doctor must then show you his before and after photos to prove that he can actually accomplish what he draws on the computer.
In your case in particular, you need to find a surgeon who understands all of the issues I mentioned, and how they fit together, and who can actually accomplish them in surgery. 

I can certainly see how rhinoplasty and chin implantation would be helpful in achieving better facial balance. It's hard to give an exact quote without know more about your treatment plan, but I am able to give that after individually assessing your concerns. You can contact my office via my DrLamperti.com website to set up an office consultation or virtual consultation.In the meantime you can learn more about combining chin augmentation with rhinoplasty at my web reference link below.

 The photograph demonstrates an overly projecting nose and an under projecting chin for which a rhinoplasty and chin implant would be an excellent combination to help with facial balance and proportions. A closed rhinoplasty approach can accomplish decreasing the overall projection of the nose, shaving down the dorsal hump, narrowing the bridge line, and refining the tip, with all the incisions placed on the inside of the nose. An open Rhinoplasty with an incision across the columella is not necessary. A small silastic chin implant can help augment the chin forward to help with facial proportions, especially with respect to the overly projecting nose. Chin implants are manufactured in a large array of sizes and shapes, and are usually placed through an incision underneath the chin. The cost of a rhinoplasty and a chin implant is directly related to the amount of time it takes to perform both procedures in a formal operating room, time monitored by a physician anesthesiologist under general anesthesia, and the surgeon's fee for performing both procedures in addition to all of the post operative follow-up appointments for one year. Digital computer imaging performed in the office setting would also be helpful to understand what can be accomplished with both procedures on your face. For more information, many before-and-after examples of this combination and our current price list, please see the link and the video below

Thanks for adding your photo.  It is hard to know if you would benefit from a chin augmentation form the photo but you would be a good candidate for a reduction rhinoplasty. 
A cosmetic rhinoplasty costs between $6000 and $7000 in the Seattle area depending upon what needs to be done and the type of anesthesia. One of the ways to get the cost of both procedures for your area is right her on RealSelf.  Just type in the procedure and you rarea in the search bar and a map with the costs paid by other RealSelf patients should come up.  The cost can be higher in certain areas and if you have special problems that will require more time and work to accomplish the look you want. It can also be lower in some areas. Be sure to look carefully at your surgeon’s before and after photos, especially the photos of any redo’s. Quality revision results are one of the great ways to determine if the surgeon you are considering does great work. Many will talk about experience and numbers but a quick look at any posted revision rhinoplasties tells you much more about the quality of their work.

I hope that helps.

Best regards.

Average cost you should expect to pay is around $10-11K.
From your pictures you appear to be a great candidate for it. You have a beautiful face and bringing the nose and chin into better relationship will augment your beauty. Looks like you need a very conservative chin implant though. Be careful. Best of luck.
