“…Several previous studies have found that patients with large ANB angles have a reduced PAS compared with control subjects. [10][11][12] In addition, maxillomandibular retrognathia appears to be a contributing factor related to airway constriction. 13 Tangugsorn et al 1 demonstrated that patients with severe sleep apnoea compared with non-severe sleep apnoea tended to display increased maxillo-mandibular retrognathism and a reduced airway space as a result.…”

Background: The use of Twin Block therapy is a well-accepted functional treatment option for the correction of a Class II malocclusion. In addition to skeletal and dental changes, its use may also promote changes in airway structure and dimension, including the size of the posterior airway space (PAS). This may be of importance in reducing the risk of developing obstructive sleep apnoea syndrome (OSAS). Materials and methods: Sixteen ( 16) subjects (eight females and eight males) underwent treatment of a Class II division 1 malocclusion via the use of a Sydney Bonded Twin Block (SBTB) appliance followed by full fixed orthodontic therapy (FFOA). Pretreatment (T1), post-twin block (T2) and post-fixed appliance (T3) lateral cephalograms were taken and skeletal and soft tissue landmarks were hand traced. A pairwise comparison was used to assess whether there were any significant differences in the cephalometric variables between each phase of treatment (T1, T2, T3). Results: The skeletal variables SNB and ANB revealed a significant change between T1-T2 (p < 0.01). The sagittal size of the nasopharynx (RPAS) also recorded a significant change between T1-T3 (p < 0.05). There was no significant change in the PAS at any stage of treatment. There was an average reduction in the ANB angle of 2° (p < 0.01) between T1-T3. Conclusions: There was no significant change in the size of the PAS following SBTB treatment. However, an increase in RPAS was recorded following SBTB treatment which continued to improve during FFOA therapy.

El objetivo del presente estudio fue comparar mediante radiografías cefalométricas, una muestra de adolescentes mestizas con las medidas estandarizadas de caucásicos de Ricketts, utilizado como patrón y determinar si hay diferencias significativas entre los valores encontrados. La población se basó en mujeres adolescentes del nivel secundario del colegio Rosa de Santa María del distrito de Breña, entre 11 a 16 años de edad. De la cual se escogió una muestra por conveniencia de 32 alumnas, con características del mestizaje peruano según patrones antropológicos. Se consideraron características extraorales e intraorales para la selección de la muestra, se utilizó el equipo de radiografía cefalométrico y una cámara fotográfica SRL para obtener un registro fotográfico de las características faciales. Los resultados fueron procesados usando el paquete estadístico SPSS v.17, expresando los resultados bajo medidas descriptivas y utilizando la prueba estadística Z para encontrar diferencias al 95% de confianza. Se concluyó que estas diferencias se hacen más evidentes en los siguientes valores: línea estética “E” 0,5 mm, ángulo ínter incisivo 124°, punto “A” a la línea N-Pg hasta en 4 mm, longitud anterior de la base craneal 56 mm, lo cual confirma la hipótesis que sí hay diferencias significativas entre la muestra de mestizas peruanas con las del grupo caucásico de Ricketts.
