Cleft lip and palate (CLP) are commonly occurring birth defects which occur due to failure of fusion of various developmental processes of the face, leading to a visible defect in the lip and palate. In severe cases, this defect may extend over the face, thus causing facial clefts. The present case of a 7-year-old girl is unique in the sense that she has right and left side facial clefts of different severity with bilateral accessory maxilla, extra set of dentition, unilateral CLP of the right side, and a double soft palate. Other less associated findings in the case are severe maxillary protrusion, complex open bite, downward and backward rotation of mandible, and incompetent lips with apparently no limb deformities. With some relevant data in hand, we present this case for various suggestions and best possible treatment plan.

OBJECTIVE: The objectives of this study were to evaluate linear and volumetric alveolar changes induced by nasoalveolar molding (NAM) in infants with complete unilateral cleft lip and palate (UCLP) and compare the maxillary dimensions after NAM with the normal dimensions in infants without clefts.
METHODS: A total of 26 infants with UCLP treated by NAM (mean age before and after NAM: 14.20 ± 8.09 days and 118.16 ± 10.06 days, respectively) comprised the treatment group, while 26 infants without clefts (mean age: 115.81 ± 8.71 days) comprised the control group. Changes in the maxillary dimensions following NAM were measured on three-dimensional models using Mimics software, version 17.0.
RESULTS: During NAM, there was a decrease in the cleft widths, maxillary arch depths, and rotation of the greater segment. While the anterior alveolar arch width exhibited a significant decrease, the posterior arch width was mostly maintained. There were no changes in the anterior vertical deviations of the alveolar segments. The alveolar crest lengths, arch circumference, and bilateral posterior volumetric measures exhibited an increase. After NAM, the anterior arch width was comparable between the treatment and control groups, whereas the posterior arch width and anterior vertical deviations were greater in the treatment group than in the control group. The maxillary arch depths, alveolar crest lengths, and maxillary volumes were smaller in the NAM group than in the control group.
CONCLUSIONS: During NAM in infants with UCLP, the cleft width and anteroposterior and transverse alveolar dimensions exhibited a decrease while the vertical dimensions were maintained. Compared with infants without clefts, those with UCLP treated by NAM exhibited sagittal and vertical alveolar growth deficiencies and tissue insufficiency.

This case report presents the management of a female patient with unilateral cleft lip and palate presenting with skeletal Class III malocclusion and a narrow upper dental arch with a midline deviation. The treatment plan involved asymmetric transverse distraction osteogenesis of the maxilla to make the upper dental midline coincident with the facial midline. After the treatment, a good facial profile and a close intercuspation of teeth were achieved. Occlusion remained stable with normal overjet and overbite after 2-year retention.
