ABSTRACT
Background. The study aimed to compare the airway morphology and hyoid bone position in children undergoing adenoidectomy or adenotonsillectomy with healthy individuals with no skeletal problems in similar age and development period. Methods. The subjects in the study were divided into three groups. These groups were defined as those having undergone adenoidectomy (53 children), those having undergone adenotonsillectomy (48 children), and the systemically healthy control group (63 children). Seventeen pharyngeal airway, nine hyoid, and four area measurements were used in the cephalometric radiographs of the children in all the groups. One-way analysis of variance was used to evaluate the children in each group. In addition, Tukey tests were used for a bilateral comparison of significant parameters. The results were considered statistically significant at P<0.05. Results. The mean age of 164 patients in the study group was 12.76±2.85 years. The vertical airway length significantly decreased in the adenotonsillectomy group compared to other groups, while the epiglottic pharyngeal length significantly increased in the former than in the latter (P<0.05). The area measurements showed that although the oropharynx area significantly increased in the adenotonsillectomy group compared to other groups, the hypopharynx and total area measurements were significantly different compared with the control group (P<0.05). No statistically significant difference was found between the three groups in all measurements of the hyoid bone position (P>0.05). Conclusion. The study showed that adenotonsillectomy operations caused more increases in the oropharynx and hypopharynx parts of the pharyngeal airway. Adenoidectomy and adenotonsillectomy operations did not contribute significantly to the hyoid bone position.
ABSTRACT
OBJECTIVE: To compare pharyngeal airway dimensions and hyoid bone position in different craniofacial growth patterns. METHODS: In total, 611 patients divided into 9 subgroups were compared according to malocclusion classification and vertical growth pattern, and these subgroups were compared in terms of pharyngeal airway and hyoid measurements. A two-way ANOVA test was used to compare the findings of the subgroups. RESULTS: No significant difference was found for the pharyngeal measurements between the groups (p>0.05). The vertical airway length (PNS-Ep) was significantly shorter in the Class III malocclusion group (p<0.05) and in the hypodivergent group (p<0.05). No statistically significant difference was found between any subgroups in any measurements of the position of the hyoid bone (p>0.05). CONCLUSION: The pharyngeal airway dimensions and hyoid bone position are similar among individuals in the sagittal direction. The vertical airway length is significantly shorter in Class III and hypodivergent individuals.

ABSTRACT
Abstract The aim of the study is to evaluate pharyngeal airway dimensions and hyoid bone position according to different Class II malocclusion types in Turkish population. Materials and Methods: The retrospective clinical study consisted of patients divided into 3 subgroups with skeletal Class II malocclusion. A total of 221 individuals (131 females and 90 males) were included in the study. Individuals with skeletal Class II malocclusion were divided into three subgroups as maxillary prognathia, mandibular retrognathia and combined. In the cephalometric analysis; 8 nasopharyngeal, 7 oropharyngeal, 2 hypopharyngeal, 9 hyoid measurements and 4 area measurements were used. The distribution of sex and growth-development stages of the patients were compared with the Pearson chi-square test. One-way ANOVA was used to evaluate patients. Tukey Post-Hoc tests were used for bilateral comparisons for significant parameters. SPSS package program was used for data analysis. Results were considered statistically significant at p0.05). When the position of the hyoid bone was evaluated, a statistically significant difference was found between the three groups in the measurements of Hy-Pg (mm) (p<0.05). Conclusion: Linear and areal nasopharyngeal airway dimensions are similar in subgroups of Class II malocclusions, while the distance of the hyoid bone from the pogonion is less in the mandibular retrognathia group.
Resumen El objetivo del estudio es evaluar las dimensiones de las vías respiratorias faríngeas y la posición del hueso hioides según los diferentes tipos de maloclusión de clase II en la población turca. Materiales y métodos: El estudio clínico retrospectivo consistió en pacientes divididos en 3 subgrupos con maloclusión esquelética de Clase II. Un total de 221 individuos (131 mujeres y 90 hombres) fueron incluidos en el estudio. Los individuos con maloclusión esquelética de Clase II fueron divididos en tres subgrupos como prognatismo maxilar, retrognatismo mandibular y combinados. En el análisis cefalométrico se utilizaron 8 medidas nasofaríngeas, 7 orofaríngeas, 2 hipofaríngeas, 9 medidas hioides y 4 medidas de área. La distribución del sexo y las etapas de desarrollo del crecimiento de los pacientes se compararon con la prueba de chi cuadrado de Pearson. Se utilizó un ANOVA unidireccional para evaluar a los pacientes. Las pruebas Tukey Post-Hoc se usaron para comparaciones bilaterales de parámetros significativos. El programa del paquete SPSS se usó para el análisis de datos. Los resultados se consideraron estadísticamente significativos a un nivel de significación p0.05). Cuando se evaluó la posición del hueso hioides, se encontró una diferencia estadísticamente significativa entre los tres grupos en las mediciones de Hy-Pg (mm) (p<0.05). Conclusión: Las dimensiones de las vías respiratorias nasofaríngeas lineales y areales son similares en los subgrupos de maloclusiones de Clase II, mientras que la distancia del hueso hioides al pogonion es menor en el grupo de retrognacia mandibular.
