TANTALUM has proved to be most satisfactory in the closure of cranial defects, as evidenced by the increasing amount of literature on the subject. Tantalum is nontoxic, noncorrosive, inert in tissue, nonabsorbable, and malleable, and is therefore desirable material for alloplastic grafts. This metal has been used with increasing frequency in reparative and restorative surgical procedures about the head and elsewhere in the body. Its value in the reconstruction of traumatic defects involving the periorbital structures and frontal sinuses was demonstrated by Turner1 in a group of 6 patients, though Conley2 had previously described its use in a patient with a postoperative defect in this region. Turner noted that small defects in the supra-orbital ridge resulted in disproportionate deformity, and, while the supraciliary arch could be spared in elective surgical procedures, this was not always possible in the extensive comminuted fractures of traumatic lesions. He used tantalum to repair the defect with excellent cosmetic result in the series reported. Tantalum has been used in similar cases at the Cleveland Clinic.
A man, aged 24, was admitted to the Cleveland Clinic on September 9, 1947. He had been in an automobile accident on August 31, 1947, when the car in which he was riding struck a tree. He was thrown from the back seat to the front and knocked unconscious for five or ten minutes. The right eye was swollen shut for three or four days, and when it opened the eye was turned downward and outward. He had. . .
