%X Background The bone graft for the alveolar cleft has been accepted as one of the essentialtreatments for cleft lip patients. Precise preoperative measurement of the architecture andsize of the bone defect in alveolar cleft has been considered helpful for increasing the successrate of bone grafting because those features may vary with the cleft type. Recently, somestudies have reported on the usefulness of three-dimensional (3D) computed tomography(CT) assessment of alveolar bone defect; however, no study on the possible implication of thecleft type on the difference between the presumed and actual value has been conducted yet.We aimed to evaluate the clinical predictability of such measurement using 3D CT assessmentaccording to the cleft type.Methods The study consisted of 47 pediatric patients. The subjects were divided according tothe cleft type. CT was performed before the graft operation and assessed using image analysissoftware. The statistical significance of the difference between the preoperative estimationand intraoperative measurement was analyzed.Results The difference between the preoperative and intraoperative values were -0.1¡À0.3cm3 (P=0.084). There was no significant intergroup difference, but the groups with a cleftpalate showed a significant difference of -0.2¡À0.3 cm3 (P<0.05).Conclusions Assessment of the alveolar cleft volume using 3D CT scan data and image analysissoftware can help in selecting the optimal graft procedure and extracting the correct volumeof cancellous bone for grafting. Considering the cleft type, it would be helpful to extract anadditional volume of 0.2 cm3 in the presence of a cleft palate.
