Summary

Autologous hair transplantation involves follicle extraction, trimming, and implantation. Follicle trimming improves efficiency and postoperative appearance, resulting in the discarded tissue known as hair follicle-derived microtissue (HFMT). In a clinical case, HFMT homogenate was applied to the FUE donor area wound, resulting in reduced pain, relief from itching, and faster healing compared to conventional treatment. This study aims to compare the effects of HFMT on FUE donor area wound healing.

Detailed description

The process of autologous hair transplantation involves three steps: FUE follicle extraction, follicle trimming, and follicle implantation. The purpose of follicle trimming is to improve the efficiency of follicle implantation and enhance the immediate postoperative aesthetic appearance. Therefore, during the follicle trimming process, the sebaceous glands and above-mentioned epidermis, partial dermis tissue, and surrounding tissue of the follicles are usually separated and discarded, and the remaining follicle tissue is implanted into the recipient area. The investigator collectively refers to the discarded tissue as hair follicle-derived microtissue (HFMT). In a clinical case, The investigator accidentally discovered that if the HFMT obtained from the follicular unit extraction (FUE) method was collected, cut into pieces, and made into tissue homogenate, and then the HFMT homogenate was used to cover the FUE donor area wound, the patient reported reduced postoperative pain and some relief from skin itching. Additionally, compared to conventionally treated wounds, the wound in the donor area healed faster. Based on these findings, this study aims to compare the effects of HFMT on the healing of FUE donor area wounds.

• Wound Heal

Interventions

Type	Name	Description
OTHER	HFMT cell suspension	Perform FUE autologous hair transplantation on the patient according to the guidelines and standard procedures. During the procedure, a hollow punch is used to individually punch out follicular units from the donor area. The epidermis, some dermis tissue, sebaceous glands, and surrounding tissue of the follicular units are separated and removed before the remaining follicular tissue is implanted into the recipient area. The separated tissue is trimmed with surgical scissors to create a cell suspension. After completion of the procedure, the HFMT cell suspension is evenly applied to the treatment group surface. Double vaseline gauze is used to cover all donor areas and is then wrapped with sterile dry gauze with moderate pressure.
OTHER	Mupirocin ointment	the Minoxidil ointment is evenly applied to the control group surface.
