“…12 PSO is often reasoned by the postulate that the tongue of CLP newborns needs to be trained to maintain a posture considered to be physiological in order to support normal language development: Based on sonography analyses of tongue movements and postoperative articulatory function in CLP children aged about 5 years, Suzuki et al concluded that those subjects could not create negative pressure in the oral cavity, regardless of previous presence or absence of an orthopedic plate. 25 This finding is confirmed by the results of our study (Table 3). However, they also reported an improvement in tongue dynamics during sucking and articulation in subjects treated by PSO, which was not substantiated by our results (Table 2-5).…”

Objective: To test the null hypothesis of no significant difference between intraoral pressure characteristics in infants with cleft lip and palate (CLP) with or without presurgical orthopedic (PSO) plates (groups CLP and CLP-PSO), compared with noncleft infants. Materials and Methods: Intraoral atmospheric pressure assessments were performed on 17 subjects with preoperative CLP (m/f, 11/6; mean/SD, 4.76/0.92 months) and a matched control group (n 5 24; m/f, 15/9; mean/SD, 4.88/0.9 months), for 200 seconds, simultaneously at the vestibulum (vestibular space [VS]) and at the palate (subpalatal space [SPS]), using a prepared pacifier connected to a digital manometer. Areas under the pressure curves (AUC), frequencies, durations, and magnitudes of swallowing peaks and pressure resting plateaus were compared between trial groups and locations (VS, SPS) using a two-factor analysis of variance for repeated measures, Kruskal-Wallis test, and Mann-Whitney U-test (a 5 .05). Results: The null hypothesis was rejected: Globally, there were statistically significant differences in intraoral pressure characteristics between groups CLP, CLP-PSO, and control (all P , .01), with significantly higher negative pressures (AUC) in the control subjects compared with those of CLP or CLP-PSO. There were significant effects by the location of pressure recordings (VS, SPS) and their interaction with all treatment groups. Differences between noncleft and CLP subjects were more pronounced in the VS than in the SPS. There was no significant effect by PSO. Conclusion: PSO does not improve deviated swallowing characteristics during suction in CLP infants. (Angle Orthod. 2016;86:315-323.)

“…When considering the treatment or prevention of palatalized articulation based on the findings of the present study, a presurgical orthopedic may play a role in improving abnormal morphology of the palate 19,20 . In our previous study on the incidence of palatalized articulation relating to treatment using a Hotz plate 21 , it was suggested that the Hotz plate improved abnormal palatal morphologies and might decrease the occurrence of palatal articulation.…”

Palatalized articulation is one of the major articulation disorders which patients with cleft palate face after palatoplasty. Various causal factors have been suggested to date, but the main cause remains poorly understood. To clarify the possible causes of palatalized articulation in speakers with cleft palate, three‐dimensional palatal morphology in patients with/without palatalized articulation in unilateral cleft lip and palate (UCLP) was analyzed. Twelve UCLP patients with palatalized articulation (P group) and 20 UCLP patients with normal articulation (N group) participated in the present study. Speech was assessed in the two groups at the age of about four. Dental casts of the maxilla taken at the same time were analyzed three‐dimensionally, and measurements in the horizontal, frontal, and sagittal planes were compared between patients with palatalized articulation and those with normal articulation. All dental casts were measured with a non‐contact 3D laser scanner and the 3D data were analyzed with 3D‐analyzing software. Our study demonstrated three major findings of palatal morphology in UCLP patients with palatalized articulation when compared with their non‐palatalized counterparts : 1) the posterior region of the palate was narrow in the horizontal plane, 2) asymmetry of the anterior palate was severe in the frontal plane, and 3) the palate was flat and shallow in the sagittal plane. These findings suggested that palate deformities can affect the lingual‐contact pattern, and may account for the backward movement of the articulation point.

“…4,5 Furthermore, continuous use of the HP until the time of palatoplasty seems to be effective for improving postoperative articulatory function. 6 Preoperative treatment with the HP causes the dimensions of the upper part of the oral cavity of an infant with unilateral complete cleft lip and palate (UCLP) to approach those of infants without a cleft. 7 Millard 8 also reported that presurgical orthopedics can be of great value in aligning the cleft alveolus, reducing the width of the cleft, and correcting the depression of the cleft alar base.…”

The Effect of Preoperative Use of an Orthopedic Plate on Articulatory Function in Children with Cleft Lip and Palate

Abstract: Continuous use of the OP up to the time of palatoplasty appeared to be effective for the postoperative articulatory function in children with complete cleft lip and palate. Inhibiting irregular movements of the tongue, the OP might assist in preventing "palatalized articulation."
