Dermabrasion by diamond fraises revolving at 85,000 revolutions per minute.

Use of a high-speed, air-driven turbo-grinder equipped with diamond fraises that revolve at 85,000 revolutions per minute has improved results in dermabrasions on the face by, it is estimated, 50%. Dermabrasions have been done with this turbo-grinder for scarring from acne, actinic damage, syringomata, lesions of adenoma sebaceum and some other facial conditions. The rapid evaporation, nonimflammability, nonnarcotic, and excellent freezing properties of Freon 12 eliminate the necessity for auxiliary cooling fans. It is thought too that the incidence of secondary infections and keloids have been decreased by use of an ointment of erythromycin (1%) topically during the healing period.
