Velopharyngeal function in cleft patients undergoing maxillary advancement.
Maxillary advancement may result in movement of the posterior border of the hard palate with its soft palate attachment, which may cause impairment of velopharyngeal (VP) function. We examined VP function before and after Le Fort I osteotomy in 15 cleft lip and palate patients. The extent of maxillary advancement was measured by means of standard cephalometric radiographs taken before and after the operation. VP function was evaluated in terms of perceptual speech assessments, pressure-flow data and nasalance scores preoperatively and 2, 6 and 12 months after the operation. The results showed that maxillary advancement resulted in impairment of VP function in 4 (27%) of the patients.

Velopharyngeal function in association with artificial obstruction of the nose: a videonasendoscopic study.
Artificial obstruction of the nose can make the nasal cavity a cul-de-sac resonator, which has clearly audible consequences. The present study compares videonasendoscopic views of the velopharyngeal mechanism in test words uttered with the nose open and obstructed in 20 subjects with a Pierre Robin sequence and in 6 subjects without this sequence. A velopharyngeal flap was constructed on 12 subjects. Videonasendoscopic findings were assessed by 3 judges with acceptable agreement. The results indicated that impairment of velopharyngeal function occurred significantly more often in subjects with a velopharyngeal flap. This was attributed to aerodynamic reasons. Clinical implications of the results are discussed.

Finnish children in foster care: evaluating the breakdown of long-term placements.
Save the Children studied risk factors associated with placement disruption or breakdown in cases where long-term foster care was intended. Before their placement in 180 foster families, most of the 234 children studied (75%) had experienced neglect. The followup time after initial placement averaged four years and two months. Achieving long-term beneficial foster care placement of children of varied ages and experiences with abuse and neglect, involved considering the needs of the foster parents who may or may not have their own children or other children in their care. Some children were reunified with their parents; careful evaluation is needed before such reunion.

Correlation between speech outcome and cephalometric dimensions in patients with diastrophic dysplasia.
Diastrophic dysplasia (DTD) is a recessively inherited form of osteochondrodysplasia, presenting with disproportionate short stature and multiple orthopedic problems. The clinical oral manifestations include either cleft palate or submucous cleft palate in at least half of the patients. Histological studies have shown alterations in growth plate, articular, laryngeal, tracheal, and ear cartilages. Mutations in the DTDST gene, which codes for the sulphate transporter membrane protein, are responsible for the disease. Thirty-three patients were studied for speech characteristics and their correlation with cephalometric dimensions. Hyponasality was observed in 13 and misarticulation of /R/, /S/, or /L/ sounds in 17 of the 33 patients. Neither of these correlated with the occurrence of palatal deformities. Hyponasality was atypical and did not correlate with the obtained nasalance scores. Cephalometric measurements reflecting the size of the orofacial area of the vocal tract were short in the DTD patients compared with those in the healthy controls. The specific speech characteristics in DTD probably result from both the altered size and shape of the vocal tract and the structural and functional abnormalities of the laryngeal and tracheal cartilages.
