One hindrance to the growing use of MRI among the cleft population is the presence of orthodontic appliances, which could result in image distortions and non-interpretability of MR images. This is particularly a challenge because individuals with cleft anatomy have a higher incidence of dental anomalies compared to the non-cleft population (Bohn, 1963; Jordan et al., 1966; Schroeder & Green, 1975). Dental anomalies are present in approximately 62% of patients with isolated cleft lip and 96.7% of patients with both cleft lip and palate (Vallino et al., 2008; Akcam et al., 2010). Previous MRI studies of the brain revealed that some appliances and dental materials cause image distortions which result in non-interpretability of MR images, while others do not interfere with visibility of desired structures (Fiala et al., 1994; Shafiei et al., 2003; Hubalkova et al., 2002; Beau, Bossard, & Gebeile-Chauty, 2015). Currently, it is not known which orthodontic appliances and materials hinder visualization of the velopharyngeal structures during an MRI. The purpose of this study is to evaluate the influence of common pediatric orthodontic appliances on VP MRI. Insights from this study will be useful in determining which patients undergoing orthodontic treatment are candidates for VP MRI. This study included nineteen participants undergoing orthodontic treatment. All participants were scanned in a 1.5-Tesla Siemens MRI machine in supine position, capturing 3D and 2D images at rest and during sustained phonation. Two of the commonly used MR sequences for the evaluation of the VP were compared. Two raters experienced in performing MRI evaluations of the velopharynx examined the MRI for distortion in 8 anatomical sites of interest. The results of this study demonstrate that some appliances such as hyrax palatal expanders and braces with stainless steel brackets are recommended for a VP MRI, while class II corrector springs are not recommended. The HASTE MRI sequence with 2D imaging techniques should be utilized, while FSE and 3D imaging techniques are not recommended. VP MRI of participants with orthodontic appliances is recommended for clinical cases when information about the LVP muscle length, LVP origin distance, and/or distance from velar knee to posterior pharyngeal wall needs to be obtained. Other forms of imaging, such as lateral cephalogram, should be utilized for this population to determine hard palate length, velar length, pharyngeal depth, and effective velar length. The presence of wire spring coils and molar bands are likely to not to interfere with the MRI evaluation. Findings from this study suggest that the presence of orthodontic appliances does not hinder visualization of all velopharyngeal structures during an MRI. Therefore, careful consideration must be made prior to disqualifying or recommending patients for VP MRI. The results of this study will be useful in determining which patients undergoing orthodontic treatment are candidates for VP MRI.Item Open Access Sensitivity to Pulse Phase Duration as a Marker of Neural Health Across Cochlear Implant Recipients and Electrodes(2021-02-08) Zhou, Ning; Dong, Lixue; Zhu, Zhen; Galvin, John, IIIItem Open Access Development of a Measure of Function Word Use in Narrative Discourse: Core Lexicon Analysis in Aphasia(2021-01) Kim, Hana; Wright, Heather Harris; Kintz, StephenItem Open Access Evaluation of the Symmetry of the Levator Veli Palatini Muscle and Velopharyngeal Closure Among a Noncleft Adult Population(2021-06) Tahmasebifard, Neda; Ellis, Charles; Rothermich, Kathrin; Fang, Xiangming; Perry, Jamie L.Item Open Access A Hybrid Machine-Learning-Based Method for Analytic Representation of the Vocal Fold Edges during Connected Speech(2021-01-27) Orlikoff, Robert F.; Yousef, Ahmed M.; Zacharias, Stephanie R.

Perceptual, instrumental (i.e., nasometry and aerodynamic pressure flow), and research MRI analyses were used during pre- and post-surgical time points at a university research clinic. Continuous positive airway pressure (CPAP) therapy was trialed following a failed surgery for residual VPD in the patient. Increases in velar length and thickness, and decreases in levator veli palatini muscle angle of origin and contraction were observed following the Furlow double-opposing Z-plasty surgery. Variable improvements in residual hypernasality following the home-based CPAP therapy protocol were observed.Item Open Access Normative Velopharyngeal Data in Infants: Implications for Treatment of Cleft Palate(2016) Schenck, Graham C.; Perry, Jamie L.; Fang, XiangmingIdentifying normative data related to velopharyngeal muscles and structures may have clinical significance for infants born with cleft palate, especially as they relate to selection of surgical intervention and post-surgical outcomes. Previous studies suggest that patients whose anatomy post-surgically is dissimilar to that of their normative counterparts are at risk for hypernasal speech. However, studies have not documented what constitutes “normal” anatomy for the clinically relevant population—that is, the infant population. The purpose of this study is to examine an MRI database (n = 29) related to normative velopharyngeal structures and provide a preliminary comparison to two selected patients with repaired cleft palate. Twenty-nine healthy infants between 9-23 months of age (Mean = 15.2 months) with normal craniofacial and velopharyngeal anatomy were recruited to participate in this study. Normative data were compared to two infants with repaired cleft palate between 13-15 months of age (Mean = 14 months). Quantitative craniometric and velopharyngeal measures from the sagittal and oblique coronal image planes were collected. Variables of interest included: levator muscle, velum, and craniometric measures. Females demonstrated significantly larger intravelar segments compared to males. White infants demonstrated significantly larger levator muscles compared to non-white infants. Infants with repaired cleft palate demonstrated increased overall levator muscle length and levator extravelar length compared to infants with normal velopharyngeal anatomy. Data from the present study provide a normative database for future investigators to utilize as a comparative tool when evaluating infants with normal and abnormal velopharyngeal anatomy.Item Open Access Nonliteral Language Processing Across the Lifespan(2021) Rothermich, Kathrin; Giorio, Cristal; Falkins, Sharon; Leonard, Lindsay; Roberts, AngelaItem Open Access Gender differences in aphasia outcomes: evidence from the AphasiaBank(2019-09) Wright, Heather Harris; Perry, Jamie L.; Fang, Xiangming; Ellis, Charles; Sharma, SaryuItem Open Access Nasometric Comparison Between Spanish-English Bilingual and English Monolingual Children(2019) Perry, Jamie L.Item Open Access Evaluating Nasalance Values Among Bilingual Mandarin–English Speakers(2019) Perry, Jamie L.; Pua, Eshan; Fang, Xiangming; Holt, YolandaItem Open Access World Cleft Coalition International Treatment Program Standards(2020) Perry, Jamie L.; Kassam, Serena N.Item Open Access Effective Velopharyngeal Ratio: A More Clinically Relevant Measure of Velopharyngeal Function(2020-11) Perry, Jamie L.; Fang, Xiangming
