Long-term effects of premaxillary setback on facial skeletal profile in complete bilateral cleft lip and palate.

The purpose of this study was to analyze the long-term effects of premaxillary setback in the surgical treatment of complete bilateral cleft lip and palate (C-BCLP). Roentgencephalograms at adolescence or early adulthood were available for 13 of our longitudinal C-BCLP patients who were treated with premaxillary setback and followed up with serial films since infancy. Six individuals had been subjected to early premaxillary setback to facilitate lip repair. Seven of the patients had had their premaxillae setback at a later age to correct a severe midfacial protrusion in the preschool years. Fourteen other C-BCLP patients, followed up and treated similarly except for the premaxillary setback, served as controls. The average long-term outcome of the setback surgery in both the early and late subgroups was retrusion of the midface and a slightly concave facial skeletal profile.

Multiple-abutment fixed partial dentures in maxillofacial prosthetics.

Ten patients were presented to illustrate multiple-abutment fixed partial dentures used in combination with auxiliary prosthetic attachments of a fixed or removable design to solve diverse problems encountered in the rehabilitation of congenital and acquired orofacial defects. While such fixed prostheses have high initial costs, their effectiveness and long-term cost-benefits suggest that, where appropriate, they represent optimum therapy that will prove most economical over the long term.

A simplified technique for fabricating a lightweight obturator.

Polyurethane foam was used as a core material in the fabrication of a lightweight obturator. This is a time-saving method of achieving a meaningful reduction in the total weight of a prosthesis while increasing strength and facilitating repair.

Bilateral congenital choanal atresia and absence of respiratory distress.

Bilateral congenital choanal atresia is considered a lethal congenital malformation in an obligatory nasal breathing neonate. Described herein are two cases of bilateral choanal atresia associated with craniofacial anomalies who did not present respiratory distress in the neonatal period. Our first patient had a complete unilateral cleft lip which facilitated oropharyngeal respiration. The second patient presented wory distress in the neonatal period by providing an oropharyngeal airway.

Cleft palate and congenital palatopharyngeal incompetency in mandibulofacial dysostosis: frequency and problems in treatment.

In a series of 25 cases of mandibulofacial dysostosis, 7 patients had isolated clefts of the palate, 1 had a complete unilateral cleft of the lip and palate, and 8 had congenital palatopharyngeal incompetency (CPI). The CPI appeared in four forms: (a) complete agenesis of the soft palate, (b) foreshortening of the soft palate associated with a submucous defect of the hard palate, (c) submucous defect of the hard palate with adequate palatal length but inadequate elevation in speech, and (d) lack of adequate palatal elevation in the absence of a submucous defect or reduced length of the soft palate. Inadequate velopharyngeal function, whether congenital or subsequent to palatal repair, may be masked by the presence of other speech problems in this syndrome, particularly by the "muffled" voice quality which appears to be associated with an elevated and retracted tongue posture. Both prosthetic and surgical treatment of inadequate velopharyngeal function are complicated in patients with MFD by other structural anomalies, particularly inadequate oral opening and constriction of the airway.

Two sisters with unoperated bilateral cleft lip and palate, age 6 and 4 years.

Two sisters with unoperated bilateral cleft lip and palate, aged 5 years 8 months and 3 years II months, are described. The degree of premaxillary protrusion in both was similar to that in unoperated infants. On the other hand, children operated in infancy showed less midfacial protrusion than the sisters following repair of their lips at a later age suggesting that the repaired lip has a long-acting effect in restricting growth of the premaxillary-vomerine complex. Later, forwards growth of the mandible and elongation of the face also serve to minimise the convexity due to the projecting premaxilla.

Training program in maxillofacial prosthetics for medical artists.

A program in maxillofacial prosthetics for medical artists was initiated at the University of Illinois Medical Center in 1966 as a joint enterprise of the Center for Craniofacial Anomalies of the Abraham Lincoln School of Medicine and the Department of Medical Art of the School of Associated Medical Sciences. In the intervening years, 25 medical artists have been graduated from the program. The general background of the trainees, the scope of their training, and their clinical contribution were discussed and illustrated.
