Hello, the reason for the lump appearance on your forehead is not a cyst, it is the appearance of the forehead bone. This lump appearance can be adressed with a well-executed forehead bone rasping operation with the help of the technological method which provides the best results and the easiest recovery (not the classical method) by entering through an incision made from your hairline in the right hands. You can achieve the look you want with this operation, which is performed with the latest technology piezo technique. Piezo technology will protect your soft tissues and provide you with maximum recovery fastly. It allows you to have a very comfortable recovery period and return to your daily life immediately! You can visit the link below to learn more about the piezo technique. I recommend investigating the long-term outcomes of your surgeon. It is the best indicator of choosing a good surgeon for you. When researching your surgeon, please note whether all of their results are similar. Some surgeons copy their results to all their patients. If you see the same face lines in all of your surgeon's results, this is an indication that he or she did not tailor his results. Unfortunately, most surgeons give similar results and rarely perform personalized surgeries like me. One golden rule: Please do not have the surgery when you feel uncomfortable and in doubt with a surgeon you hesitate. The point to consider when looking for the best surgeon is the time between your surgeon's before and after photos. Postoperative photographs must be at least 1 year after the operation. Early results and intraoperative comparison photos are of no value. Secondly, make sure that you have a good communication with your surgeon and that he/she fully understands you. You can get more detailed information about me, ask all questions about your case and sending your photos to my assistants at the number on my profile (+90 539 204 40 90). You can also book an online consultation and discuss your problems with me. With all respect.
