[Feeding, eating, and swallowing disorders in infants and children : An overview]

Swallowing is a dynamic process that requires more than 30 muscles in the recruitment/coordination of the lips, tongue, palate, pharynx, larynx and esophagus. The eating and swallowing procedure is learned in sensitive or critical periods: when a certain degree of maturation has been achieved, the appropriate stimulus permits a certain milestone of development to occur. The swallowing procedure occurs in three main stages oral, pharyngeal, and esophageal. Therefore, swallowing disorders may present in any, some, or all of these stages in addition to feeding problems. Adult dysphagia, or difficulty swallowing, has long been reported in the literature. Infants and children also experience feeding disorders and swallowing problems, either because of developmental disorders, syndromes, behavioral or neurological conditions, respiratory problems, and/or gastroesophageal reflux, eosinophilic esophagitis or anatomical deficits. Feeding problems or dysphagia are seen in up to 25% of all children; approximately 40% of prematurely born infants have swallowing disorders, up to 64-78% with developmental disorders and up to 99% with cerebral palsy. Diagnostic options include health status, broad social environment, parent-child interactions, and parental concerns. Evaluation of dysphagia and feeding disorders involves a multifactorial approach. Imaging studies may include videofluoroscopy and/or fiberoptic evaluation of swallowing (FEES). 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. An interdisciplinary team approach enables coordinated global assessment and therapy planning.
