“…Anegawa et al 28 reported that extension and flexion of the cervical spine relative to the head posture was found in connection with a change in the PAS. They stated that there was a high level of correlation between the results of posterior rhinoscopy and radiographic cephalometrics in the assessment of soft pharyngeal tissues.…”

Background/purpose: The purpose of the study was to evaluate the vertical and sagittal maxillomandibular relationship and differences in the natural head posture related to posterior airway changes in complete denture wearers using cephalometric radiographs. Materials and methods: Thirty-five complete denture wearers were evaluated cephalometrically at 3 stages. Cephalograms exposed in the natural head position at rest without a prosthesis (T 0 ), at rest with complete dentures (T 1 ), and in centric occlusion (T 2 ). Various postural and morphological landmarks were individualized on the radiographs. Results: Changes in the occlusal vertical dimension were associated with statistically significant alterations in head posture; from T 0 to T 1 extension of the head, from T 1 to T 2 flexion of the head, and cranial extension between T 2 and T 0 were significant (P < 0.001). Posterior airway dimensions significantly decreased from T 0 to T 1 and T 1 to T 2 (P < 0.001). The analysis of repeated measurements and Friedman tests were used to compare differences, and P values of <0.05 were considered significant. Conclusion: Airway protection maintenance with extension and flexion of the head is vital because any rehabilitation involves the head and neck region. Correlation coefficients indicated significant changes in dynamic measurements of the natural head position related to complete dentures. Immediate head extension and alterations of posterior airway dimensions were observed following airway obstruction because of the insertion of complete dentures.

“…Other studies have demonstrated that cephalic posture directly influences the diameter of the pharyngeal airway 7 , generates changes in cervical muscle tension 8 , and can affect respiratory support and voice quality 5 ; a correlation has been reported between the cranio-cervical posture pattern and the abovementioned factors. Cuccia and Caradonna 3 were able to conclude that dentofacial alterations can modify cephalic posture and demonstrate that nasal obstruction induces anomalous head extension, which represents a functional adaptation that facilitates oral respiration.…”

Purpose: the objective of this study was to establish an associative factor that connects the morphology of the skull -cervical system with the articulatory intelligibility level of speech in young subjects. Methods: cross-sectional study. It considered a sample of 42 university students from a universe of 140, both male and female, without morbid background and of an age range in between 18 and 21 years. Evaluated aspects: a) articulatory intelligibility by the diadochokinetic periodic variation coefficient, b) traditional static postural parameters using the photogrammetric method and c ) cephalic postural pattern by lateral cephalometric radiograph Results: 36 subjects with adequate intelligibility and 6 having altered intelligibility where cervical antero--posterior skull rotation variable showed statistically noteworthy differences ( p = 0,009 ) in between the group with normal intelligibility compared to the group with impaired intelligibility. The linear regression analysis showed that subjects with posterior rotation of head on neck show more variability in the syllabic emission of speech diadochokinetic performance (Sq r lineal = 0,128). Conclusion: it is established that cephalic position with subsequent posterior rotation of the head on the neck is associated with loss of speech intelligibility in the sample studied. Keywords: Articulation Disorders; Speech; Posture; Head; Neck RESUMEN Objetivo: el propósito de este estudio fue establecer un factor asociativo que relacione la morfología del sistema cráneo -cervical con el nivel de inteligibilidad articulatoria del habla en sujetos jóvenes. Métodos: estudio transversal, consideró una muestra de 42 jóvenes universitarios de un universo de 140, ambos sexos, sin antecedentes mórbidos y con un rango de edad entre 18 y 21 años. Se evalúo: a) inteligibilidad articulatoria mediante el coeficiente de variación periódica diadococinética, b) parámetros posturales estáticos tradicionales mediante método fotogramétrico y c) patrón postural cefálico mediante radiografía cefalométrica lateral. Resultados: se encontraron 36 sujetos con inteligibilidad adecuada y 6 alterada, donde la variable rotación cráneo cervical antero-posterior presentó diferencias estadísticamente significativas (p= 0,009) entre el grupo con inteligibilidad normal respecto al grupo con inteligibilidad alterada. El análisis de regresión lineal evidenció que sujetos que presentan rotación posterior de cabeza sobre cuello presentan mayor variabilidad en la emisión silábica del rendimiento diadocinético del habla (Sq r lineal = 0,128). Conclusión: se establece que la postura cefálica con presencia de rotación posterior de la cabeza sobre el cuello se asocia a la pérdida de inteligibilidad del habla en la muestra estudiada.
