“…These data agree with previous studies on G/BBB syndrome; however, the results indicate that most of these values are determined by the cleft. According to Akarsu-Guven et al (2015), individuals with BCLP in prepubertal, pubertal, and postpubertal stages have more retruded mandible, similar to the present results. This sample also exhibited greater lingual inclination of maxillary and mandibular incisors for BCLP and G/BBB groups.…”

“…The present findings only showed smaller airway space at the level of the posterior nasal spine in individuals with nonsyndromic cleft lip and palate, similar to the results of Akarsu-Guven et al (2015). Many factors could influence the airway space, including age and gender (Akarsu-Guven et al, 2015).…”

“…Concerning the growth pattern, there was a statistically significant increase in the y-axis in Opitz G/BBB compared with BCLP, in agreement with Brooks et al (1992), indicating a vertical growth pattern, different than the brachycephalic pattern reported by Opitz (1987). The present findings are in contrast with Akarsu-Guven et al (2015). This result should be interpreted with caution because the other growth pattern measurements were not consistent.…”

Objective: To compare the cephalometric characteristics of patients with and without Opitz G/BBB syndrome type I. Design: Cross-sectional, case–control study. Setting: Tertiary cleft center in Brazil. Participants: Eighteen individuals with Opitz G/BBB syndrome with complete bilateral cleft lip and palate (BCLP), compared to 18 individuals with nonsyndromic complete cleft lip and palate and 18 individuals without malformations, matched for gender and age. Interventions: Pretreatment lateral cephalograms of all patients were manually traced and digitized for achievement of linear and angular measurements. Main Outcome Measures: Analysis of variance or Kruskal-Wallis followed by Tukey tests were used for intergroup comparisons at a significance level of P < .05. Results: Individuals with Opitz G/BBB syndrome exhibited alterations in SNGn, P-Co, and N’-Pr/Po-Or that were not attributable to BCLP. Co-Go, Sella-Nasion-Supramentale, ANB (maxillo-mandibular relationship), and anterior nasal spine-posterior nasal spine (ANS-PNS)/U1A-U1T were significantly different in both G/BBB and BCLP groups compared to control, but not different between G/BBB and BCLP groups. Anterior nasal spine-posterior nasal spine/Go-Gn, ANS-PNS, V-Upper pharyngeal wall, and U-lower pharyngeal wall were different in nonsyndromic BLCP compared to nonsyndromic controls and Opitz G/BBB group. Conclusion: Patients with Opitz G/BBB syndrome exhibited some unique cephalometric alterations compared to patients with nonsyndromic complete BCLP and controls.

“…No significant differences of these measurements were found in both mandibular deviated group and control group. Similarly, MM 45 , FMA 46 and SN-MP 47 showing the vertical skeletal pattern, were no significant differences between mandibular deviated group and control group. According to vertical measurements, no subject with severe mandibular hypodivergency or hyperdivergency was included in the sample, because this aspect can influence airway dimensions, as described by Joseph et al .…”

The purpose of this study was to investigate the relationship between bilateral differences of upper airway and mandibular morphologic patterns in subjects with skeletal Class III mandibular deviation. 47 skeletal Class III (ANB < 0°) adult patients with and without mandibular deviation were divided into 2 groups. Bilateral differences of minimum cross-sectional area, mean cross-sectional area, volume of subdivisions (nasopharynx, palatopharynx, glossopharynx, hypopharynx) were assessed paired t test. Stepwise linear regression analysis and Pearson correlation coefficients were computed between a significant pair of upper airway variables and a pair of mandibular deviation variables to examine the quantitative relationship between the upper airway asymmetry and mandibular deviation. The mean cross-sectional area and the volume of palatopharynx on the deviated side in mandibular deviated group was significantly smaller than non-deviated side. The asymmetry index of the palatopharyngeal volume showed significant correlations with CRA asymmetry (r = 0.49) and Ramus asymmetry (r = 0.54). However, in the glossopharyngeal and hypopharyngeal segment, the mandibular deviated group showed significant asymmetry, characterized by larger mean cross-sectional area and volume in deviated side. The asymmetry index of the glossopharyngeal volume and hypopharyngeal volume showed significant correlations with CRA asymmetry (r = 0.42), Me-s (r = 0.72) and Me-s (r = 0.67) respectively.

“…Los resultados obtenidos en el estudio que se presenta no resultaron coincidentes con los reportados por Velázquez et al (11) y Akarsu Guven et al, (12) los que hallaron que la clase esqueletal II resultó predominante en individuos con LPH; esos autores emplearon el método de Steiner en base al ángulo ANB, en contraste con el presente estudio donde se utilizó el de Jacobson, (10) el identifica la longitud de la base del cráneo y el efecto rotacional de los maxilares como posibles efectos negativos en el análisis de Steiner. (9) En relación con la discrepancia ósea existente entre personas con labio y paladar hendido observada por los autores, existen similitudes con los resultados obtenidos por Corbo et al (13) y Xu et al, (14) quienes a partir de un estudio de paladar hendido aislado a lo largo de distintas edades, manifiesta que dentro de la clase esqueletal todos los pacientes mostraron una retrusión maxilar a lo largo de la infancia, adolescencia y de igual forma en la edad adulta.…”

El trabajo investigativo buscó determinar las diferencias de tipo esqueletal y de inclinación dental que se exhibe comparando medidas cefalométricas de personas con labio y paladar hendido (LPH) y personas con ausencia de cualquier trastorno bucofacial. El estudio fue de tipo observacional, descriptivo y transversal utilizando radiografías laterales de cráneo archivadas en historias clínicas de 20 individuos con labio y paladar hendido frente a 20 individuos sin fisuras bucofaciales de entre 6 y 16 años de edad. Manualmente, se realizaron los análisis cefalométricos donde el 100% de los pacientes con labio y paladar hendido presentaron clase III esqueletal, en tanto que, los individuos sin fisuras abarcan el 50% en clase I, 35% clase II y 15% clase III. La inclinación dental preponderante para los individuos con labio y paladar hendido fue de proinclinación para el incisivo inferior y retroinclinación para el incisivo superior, en tanto, el grupo de control presenta mayor proinclinación en el incisivo superior y normo inclinación para el incisivo inferior. Se logró establecer diferencias estadísticamente significativas en la inclinación del incisivo superior del grupo de control y del grupo de estudio (p=0,002; t=3,25; gl=38), además, diferencias estadísticamente significativas entre la discrepancia ósea del grupo de control y del grupo de estudio (p=0,00; U=9).
