Who was the first to advocate including the palatal periosteum in flaps used to repair cleft palate?
A. von Langenbeckvon Langenbeck. Dieffenbach was the first to repair the defect in the bone of the hard palate in 1826 by performing an osteotomy on the palatal bones and shifting a composite flap of bone and mucosa medially but von Langenbeck saw the potential of including just periosteum with mucosal flaps and designed a special elevator to achieve this end. He presented his modification of Dieffenbach’s method in 1861 in Berlin.
