title: External device for tissue expansion: clinical evaluation of the skin extender.
abstract: Tissue expansion is a well known way of repairing soft tissue defects. However, traditional tissue expanders have certain disadvantages such as the need for repeated outpatient visits for the filling of the expander and a long period of time required before the final result is achieved. A series of other devices have recently been developed. We have evaluated one of these, a skin extender developed by Blomqvist and Steenfos, in 10 lesions of the extremities in nine adult patients. The defects ranged from 3.5-10 cm wide and the extenders were inserted under local anaesthesia. The patients were taught how to tighten the extenders themselves, so there was no need for repeated visits to the outpatient department. Nine of the 10 defects were excised within 14 days; the remaining one developed a wound infection. The results show that this skin extender is a simple, fast, and economical device for repairing soft tissue defects, and in certain cases it is more suitable than a traditional tissue expander. Its major drawback is unsightly scars in the normal skin beside the previous defect.
