Abstract
An improved dissecting technique in which a balloon dissector having a predetermined inflated size and shape is placed between two naturally occurring layers and then the balloon's envelope is inflated to its full size to force these layers apart. The inflatable balloon is preferably inserted through an incision and is enclosed in a sheath which is removed prior to expansion of the envelope. Once the layers have been so separated, the balloon is deflated and extracted (either by pulling on the fill tube or by reinsertion into the protective sheath). Monitoring of the envelope's positioning is done through either endoscopic monitoring at the surgical site, or using a radiation imaging apparatus (available when the envelope has been treated to be radiopaque). Since the envelope has a predetermined inflated size and shape, the dissection is ideal for such applications as where the entire forehead is to be dissected for a browlift, or to dissect in preparation for breast augmentation.
