A tissue expansion device can be implanted temporarily beneath skin of a patient and removed upon predetermined expansion of overlying tissue. The device can include an expandable shell having a smooth or glossy outer surface and an injection port. The expandable shell can form an expandable chamber and have an anterior portion and a posterior portion. The injection port can be coupled to the anterior portion of the shell and be in fluid communication with the chamber and configured to permit injection of fluid into the chamber from a hypodermic needle. The device can have a plurality of tabs coupled to the posterior portion of the shell having one or more colors or attributes. The device can also include an orientation indicator visible along the anterior portion of the shell for assisting a clinician and orienting the device during the implantation procedure.
