Skin Expander for Scalp Reconstruction: Reappraisal of a Reconstructive Procedure for Aplasia Cutis Congenita.

Purpose: Aplasia cutis congenita (ACC) is a heterogeneous group of congenital disorders characterized by the absence of epidermis, dermis, appendages, subcutaneous tissue, and bone. The aim of the study is to describe a clinical report of ACC of the scalp treated with skin expanders.

Clinical Report: In October 2019, a 16-year-old female patient underwent scalp expansion with 2 rectangular devices (150 and 250 cm3; Radovan Mentor-Johnson&Johnson). The inflation started 30 days after surgery and continued once every 7 to 10 days to gain 10% of overexpansion. After 3 months, the patient underwent the second surgical step with the expanded scalp transposed to close the defect. Clinical examination 6 months after surgery revealed an acceptable cosmetic result with a hidden surgical scar and hair growth in the previous area of frontoparietal alopecia.

Conclusion: Skin expander for the reconstruction of extensive ACC defects of the scalp is a valid procedure.
