You may have been told that sub-glandular is a good option for you because with less tissue (muscle) covering the implant, the implant's round or teardrop shape might show through better, (giving form to an otherwise shapeless breast). However, the downside with subglandular & less tissue covering (no muscle to cover the implant) is threefold:1--there is a reported higher rate of capsular contracture-- the thick scar that forms around some implants, making them feel firm and potentially distorting them. 2--Since your breasts are small and without much gland and fat to cover the implant, you need all the coverage you can get. Without the muscle overlying the implant, the edges might show through, making the contours less soft, and potentially exposing some rippling as time goes on. 3-- with less covering, the implant will feel less soft. Having that extra layer of muscle over top gives another layer of soft natural tissue to mask what might otherwise feel firm and unnatural. So, in the end, it's about covering the implant as best possible to make it look soft, feel soft, and lower the rate of capsular contracture and surgical revisions. For you, as best I can tell without examining you, I'd recommend a shaped "gummy bear" implant placed under the muscle. That will give you the shape you're looking for but the coverage you need. Hope this helps. Good luck!
