It is difficult to tell for sure from your post whether or not you have breast implants, however, it seems as though the problem you describe has been there all along from the time you developed breasts since you state that that you have "never had a gap" between your breasts. I like your description of the "telophase stage!" In any case, what your are describing is probably a condition called "symmastia," in which the breasts approximate too closely, or sometimes touch, in the midline. Sometimes the attachments of the tissues below the skin to the underlying rib cage and sternum are also very weak, and if the breasts place enough tension on those tissues, they can distract the tissues away from the deeper structures, thereby causing a "webbed" appearance and blunting the normal cleavage. Depending upon whether you already have implants, or simply have congenital symmastia - something you were born with - will dictate how it might be corrected. In cases with implants, the solution may be to reposition the implants and reinforce the pockets around them to keep them from returning to the midline, and if there aren't implants, the solution may be to reinforce the attachments of the overlying tissues to the deeper structures to create more definition to the inner breasts and cleavage. Without any further details or an exam, it is not possible for me to offer more details than this about what such a procedure may entail. I suggest that you visit with a couple or a few board certified plastic surgeons who have extensive experience in breast surgery of all types, and preferably in correcting symmastia, so that you can be properly evaluated and all of your options can be explained to you. In addition to being certified by the American Board of Plastic Surgery, your surgeon should also voluntarily participate in the Maintenance of Certification program administered by that board. This is the best way to know that your surgeon not only has the best training and experience for the procedure, but that he or she has maintained currency in the certification requirements as opposed to practicing on a "lifetime" certificate which has only been reviewed once at the beginning of his or her career. For more information on this you can visit ABplsurg.org or ABMS.org. Good luck.
