Hi Elli. Thank you for your Question.Although many surgeons prefer the inframammary incision, current literature on incisions shows that the complication rates is the same among both transaxillary and inframammary incisions.The best incision should minimize scarring, allow safe pocket creation and safe implant insertion.The incision site is a decision that should be based on your preference along with your surgeon’s skillset in the particular incision. Your surgeon may recommend one incision over another depending on the incision’s ability to allow appropriate insertion of the implant while controlling surgical variables and reducing contamination and bleeding.With regards to the transaxillary incision, it is best for patients who have concerns for scars, who have sufficient breast tissue and normal breast shape, and who have a small areola (dark region around the nipple), or requires a small silicone or saline implant.Pros of the transaxillary (Arm pit) incision:No scars will exist on the breastThere is less trauma to surrounding breast tissues while dissecting an implant pocketIt allows surgeons to achieve hemostasis (blood-less dissection) thereby preventing hematoma where blood accumulates in the tissuesGiven optimal skill sets, you can place all types’ implants precisely into the surgical pocket.Cons of the transaxillary (arm pit) incision:If reoperations are required, an additional incision using the inframammary or periareolar approach is required to optimize control and accuracyThe axillary approach is not good for patients with tuberous breasts, constricted breasts, or with severe sagging.This approach can have an increased risk for implant malposition in the upper pole of the breast because of poor visualization of the inframammary fold.Great caution is required to prevent trauma to lymphatic vessels which are part of our immune systemYou can only do behind the muscle implant placement In many aspects, the inframammary approach surpasses the other incision locations and is best suited for patients who have a small areola (dark pigmented skin around the nipple), patients with breast sagging, and those who require large volume implants or form-stable implants. Compared to the under the armpit incision, the inframammary incision (under the breast) allows direct vision, less trauma to breast tissue, easier and precise pocket dissection, and undamaged insertion of the implants.Bottomline: Incision site depends on your scar preference, your implant size, and surgeon’s preferenceIt would be best to consult with a board-certified plastic surgeon.Hope this helps.
