Abstract

Background

Successful management of facial allotransplantation (FAT) requires planning and overcoming a long list of obstacles, not least among them, the restoration of the donor cadaver (DC).

Methods

We present an innovative single step facial reconstruction technique for the DC using light-curing material, which would simplify the infrastructure needs and optimize the time and cost associated with the traditional facial restoration techniques described in the literature to date. Simultaneously, we developed a study based on the creation of 7 facial masks over a male caucasian formoldehyde preserved cadaver head to evaluate the production time of the mask, likeness to the original face, temperature and adaptation of the mask to the defect.

Results

We found an average time for the adjustment of light-curing resin sheets (LCR) over the DC of 5 mins, 4 mins for the photopolymerization, 16.4 mins for cosmetic adjustment and application over facial defect, with a global average time of 25.4 mins. In all cases, the likeness to the original was good, and the average temperature over the donor area was 19.8 ºC. The adaptation of the mask to the facial defect was accurate in all cases.

Conclusions

This one-step technique proposed for facial restoration in the donor cadaver present a shallow learning curve, and low-cost with accurate and predictable results.
