The Dermisgraft Epithelialization and Late Scar Healing

University Hospital, Linkoeping23 enrolled

Overview

Study Synopsis Title; The dermis graft: epithelialization and late scar evaluation A Clinical Prospective multicenter trial Objectives; The objective of this study is to compare a dermal graft with a conventional split thickness skin graft regarding healing quality and scarring. Design; the study is a prospective, controlled clinical multicenter trial. Study population; Atleast 20 burn patients (18-80 years) with a full thickness burn that requires permanent skin cover. Time plan; Enrollment will continue until atleast 20 patients have been included and completed the study.

Background: Donor site morbidity is a major concern such as wound healing disturbances, hypertrophic scarring and hypo-/hyperpigmentation. The dermal graft technique is an alternative to the standard split-thickness skin graft (STSG) technique to minimize donor site morbidity. Immediate cover of the donor site after harvest leaving a non-exposed wound is a big advantage. The aim of the study was to compare the functional and aesthetic outcome between two treatment methods (dermal graft with STSG). Methods: From February 2017 to December 2020, 21 patients received a dermis graft and a regular split-thickness skin graft in a prospective randomized study design. The recipient and the donor site were compared separately regarding healing time, scarring and patient subjective satisfaction. All sites (both donor and recipient) were analyzed histologically regarding remodeling and scar formation.

Interventions

Skin transplantation to heal burn injuriesPROCEDURE

The study compare two different treatment modalities, STSG (split-thickness skin graft) versus dermis graft after excision of devitalized/necrotic tissue. A dermatome will be used for graft harvest.

Outcomes

Primary Outcomes

Healing time

Recipient sites are to be assessed regarding healing (re-epithelization) at each site (donor respective recipient). Healing will be assesed in days after surgery.

Time frame: 4 weeks

Aesthetic outcome

The aesthetic appereance regarding scarring will be assessed. A MPA580 cutometer will asses the viscoelasticity in the skin and POSAS will asses the appereance of the scar objectively as subjectively. R0 and R2 will be used as variables evaluating firmness and elasticity. POSAS will be analysed accoring to a scoring system (0-10 and 0-60).

Time frame: 12 months
