Remove the scalp by making an incision in the midline from the nasion to the external occipital protuberance. Next, make a coronal incision from the vertex of the skull to a point just above each ear.

Reflect each flap of the scalp inferiorly . Within the posterior skin flaps, identify the occipitalis muscle [cross-section].

The scalp is composed of five layers. The mnemonic "SCALP" is useful in identifying these layers:
Within the anterior flap (if present), identify
the fibers of the frontalis muscle. Identify the galea aponeurotica [frontal section] which connects the occipitalis muscle with the frontalis muscle.
