Abstract		Objectlve: The purpose of this study was to test the hypothesis that, with the use of preoperatlve treatment, the dimensions of the upper part of the oral cavity of an infant with unilateral cleft Iip and palate (UCLP) become more similar to those of a nonclett infant. Design: This was a retrospective study of upper dentar casts taken at birth and prior to Iip repair at 6 months of age. A treated group, an untreated group, and a group of noncleft contemporaries were compared cross-sectionally and longitudinally. Models were analyzed by the trigonometric method. Setting: The study was performed at a maxillofacial center servicing a population of two million. Participants: The treated group consisted of 24 babies born after 1990 with UCLP that started presurgical treatment within 20 days of life. The untreated group consisted of 25 randomly selected UCLP casts taken at birth and 25 casts taken just before lip surgery. The noncleft group consisted of 25 fullterm infants whose mothers participated in the longitudinal growth study. All participants belonged to the same ethnic group. Interventions: Presurgical treatment consisted of the babies constantly wearing a thin, passive acrylic plate mimicking the normal palate and a slim adhesive tape fixed to the lip segments to bring them slightly together. Results: The upper oral cavity in a newborn with UCLP was significantly larger than in a noncleft infant, the only exception being in the sagittal dimension. After presurgical treatment, the upper oral cavity was remodeled and slightly enlarged; there was a lesser difference from the noncleft at 6 months than at birth. The cleft in the alveolus reduced significantly, and the position of the incisive point improved. The group without presurgical treatment had no remodeling, and the growth dynamlcs were similar to the noncleft so that the dimensional differnces from the normal remained the same as at birth.
