Temporoparieto-Occipital and Temporoparieto-Occipitoparietal Scalp Flaps
T. R. VECCHIONE
The following four chapters (Chapters 4-7) describe a series of techniques for restoration or transfer of hair-bearing skin about the scalp. These flaps have found their greatest usefulness in treating acquired baldness. They are most helpful with the adjunctive insertion of microvascular grafts, as well as the use of additional free multiple and single hair-bearing grafts.
In the treatment of frontal or frontoparietal alopecias, the temporoparieto-occipital flap is the method of choice, since it provides enough hair to cover the alopecic area up to the contralateral region (1, 2, 3, 4, 5, 6). The flap can be extended if necessary as the temporoparieto-occipitoparietal scalp flap (7, 8, 9).
These flaps have the valuable advantage that the donor area is closed by approximation of its edges, at the expense of a large retroauricular advancement flap.

When the alopecia affects the frontal area (Figs. 4.1 and 4.2), only one flap will be required to close the defect. If the alopecia also involves the parietal region, a second flap from the contralateral zone is placed behind the first one a month later.
When a large area of central alopecia cannot be covered completely, an extended flap (Figs. 4.3 and 4.4) can be used not only to cover part of the defect, but also to help camouflage the remaining defect with an appropriate hairstyle.
