Excerpt from Surgical Treatment, Vol. 2 of 3: A Practical Treatise on the Therapy of Surgical Diseases for the Use of Practitioners and Students of Surgery In the treatment of injuries and diseases of the scalp, there are certain peculiarities of structure to be considered. The scalp is loosely connected to the bone by elastic connective tissue, which renders it freely movable and easily detached, excepting in infancy and old age. Its blood supply is so rich that healing is easily secured. The chief arteries are the supraorbital, temporal, and occipital, and m making large flaps these vessels should be considered. The capillaries, anastomosing venules, and arterioles are so numerous as to give the scalp almost an angiocavernous or spongy character. The veins communicate through the minute openings in the skull with the intracranial vessels so freely that infections in the scalp always threaten the venous sinuses of the brain. The structure of the scalp is so firm and so related to the vessels that when the latter are divided they do not collapse but their mouths tend to remain open and bleed. The lymphatics empty into the lymph chains of the neck. The nerve supply is largely sensory, giving rise often to neuralgias if irritated by scar tissue. The motor nerves are to the occipitofrontalis, temporal, and small muscles of the ear. The nerve to the frontalis from the facial should be guarded from injury. The external periosteum of the skull has the power to generate bone even in adults. It is adherent with especial firmness at the suture lines. The deepness of the hair follicles and glands of the scalp renders perfect cleansing by mechanical means impossible. Iodin 1n alcohol or other penetrating antiseptic solution must be used for cleansing. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
