“…US uses reflected sound as an imaging tool, which has been applied to visualize temporal relationships between movement patterns of oral and pharyngeal structures in fetal swallowing [Petrikovsky et al, 1996;Miller et al, 2003Miller et al, , 2006Grassi et al, 2005], premature infants [Miller and Kang, 2007], young infants [Bosma et al, 1990], and in older children and adults [e.g., Shawker et al, 1984;Fanucci et al, 1994;Yang et al, 1997].…”

Assessment of infants and children with dysphagia (swallowing problems) and feeding disorders involves significantly more considerations than a clinical observation of a feeding. In addition to the status of feeding in the child, considerations include health status, broad environment, parent-child interactions, and parental concerns. Interdisciplinary team approaches allow for coordinated global assessment and management decisions. Underlying etiologies or diagnoses must be delineated to every extent possible because treatment will vary according to history and current status in light of all factors that are often interrelated in complex ways. A holistic approach to evaluation is stressed with a primary goal for every child to receive adequate nutrition and hydration without health complications and with no stress to child or to caregiver. Instrumental swallow examinations that aid in defining physiological swallowing status are needed for some children. Successful oral feeding must be measured in quality of meal time experiences with best possible oral sensorimotor skills and safe swallowing while not jeopardizing a child's functional health status or the parent-child relationship.

“…The few studies dealing with this topic have focused on the sonographic appearance of the fetal upper airways as obtained by means of two-dimensional ultrasound (Cooper et al, 1985;Wolfson and Laitman, 1990;Richards and Farah, 1994). More recently, the introduction of high-resolution sonography combined with spectral and colour Doppler techniques has allowed a precise description of the behavioural patterns of the upper respiratory tract with regard to respiration, swallowing and phonetics in the human fetus (Isaacson and Birnholz, 1991;Petrikovsky et al, 1996;Ló pez Ramó n y Cajal, 1996;Kalache et al 1997a). Among other things, these studies have shown that the anatomical shape of the upper airway might be influenced by these different functions.…”

Ultrasound measurements of the diameter of the fetal trachea, larynx and pharynx throughout gestation and applicability to prenatal diagnosis of obstructive anomalies of the upper respiratory-digestive tract

The purpose of the present study was to obtain normative data for the fetal upper respiratory tract by using high‐resolution ultrasound techniques. Furthermore, we wanted to test the potential utility of the resulting normograms in diagnosing obstructive lesions of the trachea and oesophagus. Sonographic measurements of the diameters of the trachea, larynx and pharynx were obtained at well‐defined planes from a prospective cross‐sectional sample of 198 normal patients of known gestational age between 15 and 40 weeks' gestation. All measurements were performed during fetal apnea and in the absence of swallowing. The same measurements were also obtained from two cases with laryngeal atresia and three cases with oesophageal atresia, all of which were diagnosed prenatally. The data obtained were plotted on the constructed normograms. In normal fetuses approximately linear relationships existed between tracheal, laryngeal and pharyngeal diameter, on the one hand, and gestational age, on the other, with the measurements correlating significantly (p<0·0001) with gestational age. The linear regression coefficients (r2) for the tracheal, laryngeal and pharyngeal diameters were 0·66, 0·55 and 0·32, respectively. The 95 per cent prediction limits were also calculated. In fetuses with laryngeal atresia only the tracheal diameter was significantly higher as compared with that of normal fetuses. Data of the fetuses with oesophageal atresia showed that there were no changes in the upper airway anatomy. Our study provides normative data for the upper respiratory tract. In the prenatal diagnosis of obstructive neck anomalies the usefulness of the data would seem to be limited to those affecting the respiratory tract. Among the structures measured, only the trachea may prove to be of clinical significance. Copyright © 1999 John Wiley & Sons, Ltd.

Detailed assessment of the larynx is not easy because of its complex structures and the associated technical difficulties. We performed sonography in multiple planes to assess the laryngeal anatomy and movements of a fetus with laryngeal atresia. The distended trachea ended abruptly with an echogenic non‐structured larynx which showed shallow rapid “flutter‐like” movements and up and down but not adduction‐ abduction movements during swallowing. Shadowing from the chin could be reduced by scanning through fluid in the oral cavity or between the transverse processes of vertebrae in a coronal plane.
