Conventional reconstructive procedures for face and scalp reconstruction fall short of aesthetic and functional goals because of the unique quality and quantity of facial and scalp soft tissue. The purpose of this cadaver study was to demonstrate the feasibility of a flap design for full face and scalp composite tissue allotransplantation, without cutaneous facial scars. Six fresh human cadavers were dissected with sagittal scalp and mucosal incisions for full face and scalp harvest without cutaneous facial incisions. Sub-galeal and sub-SMAS dissection allowed for inclusion of the external carotid and internal jugular systems. Time of facial-scalp flap harvesting, length of the arterial and venous pedicles, length of sensory nerves (that were included in the facial flaps) and approximate surface area of the flaps were measured. Three of six flaps were transferred to recipient cadavers and the time of transfer was recorded. As a proof of concept, the external carotid arteries of one of six cadavers was flushed to remove clots and perfused with a radio-opaque latex polymer, Microfil (Flow Tech Inc.), to study flap perfusion by X-ray imaging. In the donor cadaver, the mean harvesting time of the total facial-scalp flap was 105 ± 19 minutes. The mean length of the supraorbital, infraorbital, mental and great auricular nerves were 1.3 ± 0.2, 1.3 ± 0.1, 1.3 ± 0.1, and 4.8 ± 0.6 cm, respectively. The mean length of the external carotid artery and external jugular vein were 8.7 ± 0.3 and 9.2 ± 0.4 cm, respectively. The approximate area of the harvested flap was 1063 ± 60 cm2. In preparation for full face and scalp allotransplantation in humans, this study has demonstrated the feasibility of a full face and scalp flap without visible facial incisions.
