An envelope contains 60 pieces of paper on which groups A and B are written, and there are 30 pieces of each group in the envelope. Group A is assigned to the Mercedes surgery method and group B is assigned to the inverted V surgery method. Before performing the surgery, the surgeon takes out a paper from the envelope for each patient and the surgical method is selected based on the type of group, Blinding description: Before the operation, after choosing the type of operation, the surgeon and the researcher are aware of the type of operation, but after the surgery and subsequent examinations and data reporting, other residents of the center are used for examination, who are assigned a code for each type of operation. It is possible that only the researcher is aware of it. N/A Patients referred for abdominoplasty and breast reconstruction with abdominal flap. Intervention 1: Intervention group: In this group, the Mercedes surgical method is used, where a marking with methylene blue on the two lateral and upper wings between 0.5 and 1.0 cm from the central point is determined, and they form the "Y" suggested in this technique. At this point, the skin is cut above the Y mark. To prevent umbilical stenosis, two "cuts" are removed from the side flaps of the Y to allow the umbilical suture to fit better. Intervention 2: Control group: In this group, we use the inverted V surgery method, where the arms of the incision are approximately 1.5 to 2 cm and are separated by a distance of approximately 1.5 to 2.5 cm at the base. An inverted V-shaped skin flap is raised at a predetermined, palpated umbilical point. Yes - There is a plan to make this available What will be shared: The written informed consent form will be provided to the participants after the procedure and will be included in the thesis. We have also published it in the Pajuheshyar system The data of the study also includes the results of the variables, including the level of satisfaction with the form of not causing complications When: The consent form will be placed in the attachments section after the thesis is printed. Also, the data of the participants is included in the thesis To whom: All people who have access to the full text of the thesis Conditions: It can be modeled in similar studies Where to obtain: Email to the general supervisor of the thesis Dr. Vahab Rezaee vahab_rezaee@yahoo.com How to obtain: After sending the email to the general supervisor, the thesis can be received within 1 week Comments:
