[Histologic and anatomic correlation of the infraorbital region]

The infra-orbital area has not been well studied although it represents an interesting area in plastic surgery because of its implication in malarplasty reduction or transplantation for facial tissue repair. This work comprises an anatomic dissection layer by layer and a histologic study describing the various structures of this area. It was performed on 10 heads taken from cadavers (mean age 70 years old). The anatomic and histologic study found four layers: a subcutaneous fat layer, a muscular layer, a deep fat layer and a deep muscular layer. The superficial fat layer constitutes the convexity of the cheek and can be removed in plastic surgery reduction or reconstituted after atrophy following nasolabial musculo cutaneous flaps.
