ABSTRACT
The following case report describes the expanding role of pediatric dentists in treating children with craniofacial pathology. Retinoblastoma is the most common intraocular malignancy in childhood and is approximately the tenth most common pediatric cancer in the United States. Treatment consists of enucleation, or removal of the entire globe followed by placement of orbital implants. Un-restored anopthalmic sockets exhibit growth retardation and can lead to facial disfigurement. Maxillofacial prosthetic (MFP) rehabilitation can be especially challenging in younger, pre-cooperative or behaviorally compromised children and requires the skills and participation of a pediatric dental specialist as part of the MFP team. The following case report involving a 3 yr-old girl with retinoblastoma describes such challenges. The objective of the maxillofacial prosthetic team was to provide custom-built, acrylic, bilateral ocular prostheses in as comfortable and atraumatic manner as possible. The case was a success and underscores the value of a multidisciplinary dental approach for the treatment of children with very special needs.

The purpose of this study was to clarify the differences in the nature of craniofacial growth between subjects with normal occlusion and patients with unilateral cleft lip and palate (CLP) in terms of the size, shape and principal growth direction of craniofacial skeleton using finite element method (FEM). Lateral cephalograms were taken of 40 subjects as normal group and 178 patients as CLP group. These subjects were divided into seven developmental ages of 4-, 6-, 8-, 10-, 12-, 14- and 18-year-old. For the finite element analysis, the craniofacial complex was discretized into seven structures or elements with three nodal points in each after tracing each lateral cephalogram on acetate paper. For each stage, the growth parameters in CLP group were compared to those in normal group. The growth of upper facial skeleton and maxillary complex was more remarkably inhibited in CLP than in normal group. Especially, the growth inhibition of posterior maxillary complex in a vertical direction was remarkable in CLP group at any ages. Difference in the size and shape of entire mandibular skeleton between CLP and normal groups was not apparent. It is suggested that grow timing and peak velocity, an essential and key determinant to the success in orthodontic treatment, have been clarified in this study more clearly than in previous studies. It is hopefully anticipated to explore some key determinants to predict individual growth of the craniofacial skeleton near future.
