Tissue expansion is of value in the repair of some defects produced by
Mohs micrographic surgery. In particular, defects of the nose, forehe
ad, temple and scalp as well as extensive defects in other areas may r
equire expansion. Tissue expansion should be considered prior to Mohs
micrographic surgery in these cases. Intraoperative and rapid expansio
n are useful adjuncts to other repair options. Complications of expans
ion are frequent and must be anticipated.
