Department of Oculoplastic, Orbital and Lacrimal Surgery, Aichi Medical University Hospital, Nagakute, Japan.
Purpose: To describe a technique using retroauricular scalp graft for eyebrow reconstruction, along with problems encountered and countermeasures in treatment.
Methods: We present a patient with eyebrow loss following resection of a malignant schwannoma. We initially covered the defect from the upper eyelid to the eyebrow area with artificial dermis for hemostasis and to increase the granulation of the graft bed.

The hair follicle is a complex of mesenchymal and epithelial cells acquiring different properties and characteristics responsible for fulfilling its inductive and regenerative role. The epidermal and dermal crosstalk induces morphogenesis and maintains hair follicle cycling properties. The hair follicle is enriched with pluripotent stem cells, where dermal papilla (DP) cells and dermal sheath (DS) cells constitute the dermal compartment and the epithelial stem cells existing in the bulge region exert their regenerative role by mediating the epithelial-mesenchymal interaction (EMI).

Tissue engineering utilizing hydrogel scaffolds in combination with exogenous stem cells holds significant potential for promoting wound regeneration. However, the microenvironment provided by existing skin tissue engineering scaffold materials is often inadequate. Herein, we demonstrate an enzyme-crosslinked hyaluronic acid hydrogel to provide a growth microenvironment for exogenous bone marrow mesenchymal stem cells and promote acute wound healing.

Keratinocyte carcinomas (KCs) are commonly located on the scalp and often treated with excision with peripheral and deep en face margin assessment (PDEMA), with Mohs micrographic surgery (MMS) being the most frequently used method. Resection of these malignancies results in wounds with a wide variety of sizes, ranging from small, sub-centimeter defects, to extensive, nearly complete scalp defects. MMS is often the preferred treatment for tumor resection and margin clearance, as it allows for maximal healthy tissue preservation and has the lowest recurrence rates.
