Vocal cord paralysis: radiologic observations in 21 infants and young children
Insights
Vocal cord paralysis or paresis is more common in infants and children than previously thought. Over half of cases are transient, highlighting the importance of recognizing early diagnostic signs.
Area of Science:
- Pediatric Otolaryngology
- Pediatric Radiology
Background:
- Vocal cord paralysis or paresis in pediatric patients is often considered rare.
- Accurate diagnosis is crucial for timely intervention and management.
Purpose of the Study:
- To evaluate the incidence and nature of vocal cord paralysis or paresis in infants and children.
- To assess the role of radiographic and fluoroscopic examinations in the initial diagnosis.
Main Methods:
- Direct laryngoscopic examination was used for diagnosis in 34 infants and children.
- Radiographic and fluoroscopic examinations were performed in 21 of these children prior to laryngoscopy.
Main Results:
- Vocal cord paralysis or paresis was diagnosed in 34 pediatric patients over 4 years.
- Radiologists initially suggested the diagnosis in over half of the cases examined radiographically.
- More than 50% of the diagnosed vocal cord dysfunctions were transient.
Conclusions:
- Vocal cord paralysis or paresis is not as rare in pediatric populations as previously reported.
- Radiographic and fluoroscopic findings can suggest the diagnosis, aiding early supportive therapy.
- Transient vocal cord dysfunction is common in this age group.
Abstract:
The diagnosis of vocal cord paralysis or paresis was made on direct laryngoscopic examination in 34 infants and children during the past 4 years. Twenty-one of the children were first examined radiographically and fluoroscopically, and the initial diagnosis of cord paralysis was suggested by the radiologist. Our experience suggest that vocal cord paralysis or paresis in an infant or young child is not the rare entity previously reported. In more than half of the children the vocal cord dysfuction was of a transient nature. Awareness of the radiographic and fluoroscopic signs that suggest the diagnosis will aid in the early institution of appropriate supportive therapy.
