Breast augmentation also known as breast enlargement, breast enhancement or a boob job is one of the most popular aesthetic surgical procedures and for good reason. The results can be confidence-inspiring and truly transformative. The process involves the insertion of silicone implants into the chest which sit either on top of or below the pectoral muscle. The procedure is performed under ClearSleep anaesthesia and the most common surgical approach is via the inframammary fold or IMF. The periareolar and transaxillary approaches are much less commonly performed in the UK.
