Objectives:
To evaluate videofluoroscopic swallow study (VFSS) findings in infants with dysphagia and without prior diagnoses, and to characterize the outcomes and any diagnoses that follow.
Methods:
A chart review of all pediatric patients who received a VFSS at a tertiary children's hospital from November 2008 to March 2017 was performed.
Results:
There were 106 infants (57 males and 49 females) with 108 VFSS. VFSS was normal in 18 (16.98%) infants. Regarding airway protection, 50 (47.17%) infants had laryngeal penetration, and 8 (7.55%) had tracheal aspiration; 3 (2.83%, 37.5% of all aspirators) exhibited silent aspiration. Of the 75 infants with minimum 2-year follow-up, 35 (46.67%) had no sequelae of disease and received no diagnoses. The most common diagnoses and pathologic sequelae were gastroesophageal reflux (n = 18, 24.00%), asthma (n = 8, 10.67%), laryngomalacia (n = 6, 8.00%), and tracheomalacia (n = 4, 5.33%), all consistent with United States pediatric data on prevalence. All infants (n = 51) with follow-up for dysphagia had resolution of symptoms within 9 months from VFSS order date.
Conclusions:
Otherwise healthy infants may show signs of dysphagia and not develop later illness. Parents can thus be counseled on the implications of dysphagia in a previously healthy infant. Our findings provide comparative statistics for future research in pediatric dysphagia.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
