5 - Scalp
Published online by Cambridge University Press: 20 October 2009
Summary
The scalp represents one of the most homogenous and least complex anatomic regions of the head and neck. However, its unique characteristics and subtleties make reconstruction both challenging and rewarding. The broad, inelastic nature of the galea aponeurotica, which encompasses the scalp as a tendonlike sheath under constant tension, lends the scalp its less mobile characteristic. The anatomy is unlike any other, providing both benefits and drawbacks during reconstruction. Primary closures, flaps, and grafts may all be utilized to reconstruct the scalp, though their application can be very different when compared to other parts of the face. As such, and in comparison to facial skin, extensive undermining is often necessary during scalp reconstruction. The scalp is comprised of five layers: skin, subcutaneous connective tissue, galea, subaponeurotic loose areolar tissue, and pericranium. Scalp laxity can vary by age, location, and from person to person. Scalps in infants, for example, are quite loose and mobile. As one ages, this changes dramatically. The crown of the scalp usually is the least mobile, whereas the peripheral scalp is more distensible.
