What is considered a large breast implant? What is considered a wide chest? (photos)

Thank you for the good question.  Generally speaking, I do not think that it is helpful to individual patients to classify breast implants as "small or "large".  For example, 400 breast implants on a very petite patient may be too "large" whereas 800 cc breast implants on a bigger frame may be too "small". In other words, arbitrary statements such as "breast implants larger than 600 cc are considered large" are not helpful when it comes to clinical practice.
 What IS important: appropriate selection of breast implant size/profile to safely achieved patients aesthetic goals.  Ultimately, careful communication of your goals (in my practice I prefer the use of goal pictures, direct examination/communication in front of a full-length mirror, in bra sizers, and computer imaging) as well as careful measurements (dimensional planning) will be critical.
 Generally speaking, the best online advice I can give to ladies who are considering breast augmentation surgery ( regarding breast implant size/profile selection) is:1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. ***Ask to see lots of examples of his/her work.2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. 
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. For example, I have found that the use of words such as “natural” or "C or D cup" etc means different things to different people and therefore prove unhelpful.Also, as you know, cup size varies depending on him who makes the bra; therefore, discussing desired cup size may also be inaccurate. Again, the use of computer imaging has been very helpful during the communication process, in our practice.3. Once you feel you have communicated your goals clearly, allow your plastic surgeon to use his/her years of experience/judgment to choose the breast implant size/profile that will best meet your goals. Again, in my practice, this decision is usually made during surgery, after the use of temporary intraoperative sizers.I hope this (and the attached link, dedicated to breast augmentation surgery concerns) helps. Best wishes for an outcome that you will be very pleased with.

   High profile are taller and narrower implants when compared to moderate profile implants of the same volume.The decision is usually based on the patient breast dimensions, amount of breast that the patient can contribute to the projection and I also factor the patients desires. I try my best to also respect the skin quality and elasticity in order to prevent future drooping due to unnecessarily heavy implants.   over or under muscle doesn't dictate what size implant we can use.  The muscle coverage is helpful in very thin patients and seems to reduce capsular contracture according to some scientific studies. Under the breast tissue is the most natural feel and has a less chance of animation deformity when the pectoralis muscle contracts. In most instances only the top implant is covered by muscle and the reset of the implant ends up under the breast tissue.   What are the basic tips to know if I need a breast augmentation or breast lift? It all depends on the position of the nipple on the breast. The further down the nipple is in relation to the fold the more the chances are the patient needs a lift.Choose a board certified plastic surgeon who has done a ton of Breast Augmentation and has privileges to do this surgery at a local university hospital. This says his credentials have been checked out by fellow Drs. All surgeries carry risk, talk to your plastic surgeon and choose one wisely.Many surgeons, including myself, offer online virtual consultations where you send us your photos and we can estimate the cost. I, like many surgeons, also offer free consultations so that you can be examined and given the most accurate quote possible. Please be mindful that the in person physical exam is the most important and could potentially alter your treatment plan.
