What kind of procedure/procedures do you recommend to create more distance between neck and chin? (photo)

The rhinoplasty procedure would involve shaving down the hump and de-projecting the nose.   A chin implant can be inserted at the same time through a sub mental approach to give more projection to the chin area. Chin implants are manufactured in  a variety of sizes and shapes which is best determined at the time of consultation. Sub mental liposuction below the chin area would help accentuate the results of the chin implant. 

  The best result will probably be obtained by chin augmentation and neck lift to improve the angle.Find a board certified plastic surgeon who performs hundreds
of chin implants, neck lifts, and facial procedures each year. Then look at the
plastic surgeon's website before and after photo galleries to get a
sense of who can deliver the results. Kenneth Hughes, MD Los Angeles, CA

Unfortunately, without seeing your entire face and neck in a picture, it is difficult to give advice.  However, the side view suggest that you may have a small chin, such that either a chin implant or bony genioplasty would be helpful.  Perhaps consider sending in a full photo.
