Fascial layers of the scalp. A study of 48 cadaveric dissections.

The arrangement and structure of the fascial layers of the scalp were studied in 48 red neoprene latex-injected cadavers with the aid of an operating microscope. The galea aponeurotica was continuous with a superficial temporal fascia. Deep to the galea, the subaponeurotic connective tissue was bilaminar. There was an outer, vascular, areolar layer, and an inner, avascular, membranous layer. Underlying the temporalis muscle, the pericranium was thinner and more adherent than elsewhere with no subpericranial tissue.
