“…The use of a SUP registration as the baseline measure for change in head and cervical spine added further strength to the experimental design as this posture is highly reproducible and ensures that not only the head but also the cervical spine is in the natural position [15,21]. In the SUP the reproducibility of both cranio-cervical [17] and pharyngeal/hyoid measures [9] is highly reliable.…”

Difficulty with singing is a rare but important complication following cervical spine surgery but there is little objective information regarding the cervical and head postural changes taking place during singing. The aim of this study was to identify postural changes in the cranio-cervical region associated with the demands of voice production in professional opera singing. The two Roentgen-cephalograms, one of which are taken whilst performing a specified singing task were taken from 18 professional opera students, 12 females (mean age 20.86 ± 3.07 years) and six males (18.66 ± 1.36 years). A paired t test compared mean cranio-cervical postural and pharyngeal/hyoid variables between the two registrations (P = 0.05). The association between the craniocervical postural variables and the pharyngeal/hyoid region in each registration position was examined using Spearman's rank correlation coefficient. In singing, the position of the atlas with respect to the true vertical (P \ 0.001), the axis (P \ 0.001) and the C4 vertebra both with respect to the horizontal (P \ 0.001), and the axis with respect to the cranium (P \ 0.001), were all significantly different to those at rest. Of the cranio-cervical postural variables in the singing registration, the angles measuring positional change of the atlas and C4 relative to the true horizontal were shown be significantly related to an increased pharyngeal airway space at the C3 level (P \ 0.01). An appreciation of the requirement for the cervical spine to undergo postural change during professional opera singing has relevance to the potential impact on voice quality in professional opera singers should they undergo cervical spine surgery.

“…However, the absence of a direct relationship between the cause of respiratory obstruction and its effect on craniofacial growth (Paskay; Adamidis & Spyropoulos; Cheng et al, 1988;Malkoc et al; has led to considerable controversy in the literature. The most widely accepted theory is that tonsil hypertrophy, which leads to pharyngeal obstruction, causes mouth breathing (Paskay), with the child altering the position of the orofacial muscles and of the mandible.…”

“…Perfect sealing of the oral cavity, contraction of the masseter muscle which helps the dental occlusion, necessary for swallowing, was observed in normal swallowing. Lip incompetence and effort on the perioral muscles to help swallowing, and, in some cases, spilling of content from the labial commissure and interposition of the tongue to help incompetent lip sealing have been observed in adapted swallowing (Peng et al, 2003(Peng et al, , 2004Bertolini et al;Malkoc et al).…”

“…Recent studies have evaluated airway space and hyoid bone position in month breathing and obstructive sleep apnea (OSA) (Malkoc et al, 2005;Machado Júnior & Crespo, 2010;Kikyo et al, 1999;Bibby, 1984). Although there is a close relationship between swallowing and breathing are no studies that relate to atypical swallowing radiographic anatomy of the airway space and its possible correlation with the radiographic position of the hyoid bone.…”

evaluation of the airway space and hyoid bone in children with atypical deglutition: correlations study. Int. J. Morphol., 30(1):341-346, 2012. SUMMARY:Although there is a close relationship between swallowing and breathing are no studies that relate to atypical swallowing radiographic anatomy of the airway space and its possible correlation with the radiographic position of the hyoid bone. The aim was to evaluate the possible correlation with the radiographic position of the hyoid bone and airway space in lateral radiographs of children with atypical deglutition. Using cephalometric analysis on lateral teleradiographs, the distances of H-MP (hyoid to mandibular plane) and H-T (hyoid to tuber) were Spearman's correlation analysis was performed with PAS (airway space) in two groups: the experimental group with atypical deglutition and the control group normal deglutition. Both groups included subjects in mixed dentition stage. The variable T-H had statistically significant correlation with PAS (0.0286) and the variable MP-H had significant correlation with variable PAS (0.0053). Our results show that advanced positive correlation of the radiographic position of the hyoid bone to the airway space only in the group of normal swallowing. The lower airway in patients with atypical swallowing, causing changes in tongue posture which leads to change in the position of the hyoid bone.

CONTEXT AND OBJECTIVE: Although there is a close relationship between swallowing and breathing, there are no studies evaluating the radiographic anatomy of the airway and its possible correlation with the radiographic position of the hyoid bone. The aim of this study was to evaluate the possible correlation of the radiographic position of the hyoid bone and airway space (PAS) in lateral radiographs on children with atypical deglutition, in comparison with those with normal swallowing. DESIGN AND SETTING: Cross-sectional analytical study with control group in a public university. METHODS: Using cephalometric analysis on lateral teleradiographs, the distance from the hyoid bone to the mandibular plane (MP-H) and the distance from the hyoid bone to the tuber (T-H) were correlated with the PAS measurement (airway) in two groups: 55 teleradiographs in the experimental group (with atypical deglutition) and 55 teleradiographs in the control group (normal deglutition). Both groups included subjects at the mixed dentition stage. RESULTS: The variable T-H presented a statistically significant correlation with PAS (0.0286) and the variable MP-H had a significant correlation with the variable PAS (0.0053). This positive correlation was significant only in the control group and not in the group with atypical swallowing. CONCLUSIONS: There was a positive correlation between the MP-H and PAS measurements and between the T-H and PAS measurements only in the group with normal swallowing. These correlations were not observed in the group with atypical swallowing.RESUMO CONTEXTO E OBJETIVO: Embora haja estreita relação entre respiração e deglutição, não existem estudos que avaliem a anatomia radiográfica de via aérea e sua possível correlação com a posição radiográfica do osso hioide. O objetivo deste estudo foi avaliar possível correlação da posição radiográfica do osso hioide e do espaço aéreo na radiografia lateral de crianças com deglutição atípica quando comparada com aquelas com deglutição normal. TIPO DE ESTUDO E LOCAL: Estudo transversal analítico com grupo controle em universidade pública. MÉTODOS: Por meio de análise cefalométrica em telerradiografias laterais, foi correlacionada a distância do osso hioide ao plano mandibular (MP-H) e do túber ao osso hioide (T-H) com a medida do espaço da via aérea (PAS) em dois grupos: 55 telerradiografias do grupo experimental (com deglutição atípica) e 55 telerradiografias do grupo controle (deglutição normal). Ambos os grupos incluíram indivíduos em fase de dentição mista. RESULTADOS: A variável T-H apresentou correlação estatisticamente significativa com PAS (0,0286) e a variável MP-H teve correlação significativa com a variável PAS (0,0053). Esta correlação positiva foi significativa apenas no grupo controle e não no grupo de deglutição atípica. CONCLUSÕES: Há correlação positiva entre as medidas MP-H e PAS e entre as medidas T-H e PAS somente no grupo de deglutição normal. Estas correlações não foram observadas no grupo de deglutição atípica.I DDS. Researcher,
