The charts and records of 350 cases of harelip and cleft palate have been reviewed. These cases were selected because, with the exception of 4 which were added to make an even number, the data are recorded by the classification and plan (figs. 1 and 2) suggested a number of years ago by Dr. John Staige Davis and myself.
This classification is based on a series of congenital clefts which involve the face and jaw. The condition of the alveolar process, i.e., whether it is normal or cleft, is emphasized to the point that it is the deciding factor in describing the cases. Three main groups naturally follow: Group I. prealveolar cleft; Group II, postalveolar cleft, and Group III, alveolar cleft. Thus new terms of description are evolved to designate the case as a whole.
