The keyhole method is a type of chest reconstruction top surgery which involves a small incision along the border of the areola, through which the surgeon carefully removes the chest tissue..This procedure involves very minimal scarring. It creates a small scar up to half the length around the areola border. There is no excess skin removed at all in this procedure, and therefore it is only available to patients with minimal chest tissue and relatively elastic chest skin—thus, only about 5% of the population are good candidates for this type of surgery
The surgeon first makes an incision alongside the areola, and cuts through the top of the chest tissue, leaving behind a uniform layer of thickness of fat beneath the skin that matches the thickness of the surrounding chest. The surgeon then removes the unwanted chest tissue. . All chest tissue is sent off to a pathologist to check for cancer, though actually finding any is extremely rare.
Once the chest tissue is removed, the surgeon may perform liposuction along the borders of the tissue excision to provide a smooth and uniform result.
Often, the surgeon places a drain and then closes the incision. The drain is usually in place for about seven days after surgery and is then removed.
After the procedure, the patient may experience significant numbness of the chest. Sensation usually returns with time, often ultimately feeling the same as before surgery.
