Abstract
A review of the hospital records from the Department of Surgery of the Royal Frederiks Hospital in Copenhagen when S. A. V. Stein was in charge (1844–1854) has disclosed descriptions of two operations which add further to the picture of Stein's creative talents in the field of Lip-flap plasty. In one operation, performed in 1848, Stein reconstructed the columella by means of a bi-pedicled flap from the philtrum of the upper lip. In the second operation (1852), he devised the single-pedicled, triangular, full-thickness lip flap which was later named after Robert Abbe.
