Insights
Pediatric vocal fold paralysis has varied causes. Left-sided paralysis often stems from cardiovascular issues, while bilateral cases are linked to congenital malformations, with both showing poor prognosis.
Area of Science:
- Pediatric Otolaryngology
- Pediatric Pulmonology
- Pediatric Cardiology
Background:
- Vocal fold paralysis (VFP) in children presents unique diagnostic and management challenges.
- Understanding the specific etiologies and clinical features is crucial for effective patient care.
Purpose of the Study:
- To investigate the causes and clinical characteristics of VFP in pediatric patients.
- To offer insights for improved diagnosis, treatment, and prognosis.
Main Methods:
- Retrospective analysis of 207 children diagnosed with VFP.
- Inclusion of follow-up data to assess outcomes.
Main Results:
- Left-sided VFP (151 cases) primarily caused by pulmonary arterial hypertension.
- Bilateral VFP (43 cases) associated with respiratory issues and congenital tracheoesophageal malformations.
- Right-sided VFP (13 cases) linked to intracranial lesions (8 cases) or idiopathic (2 cases).
Conclusions:
- Cardiovascular diseases are the leading cause of left-sided VFP.
- Congenital tracheoesophageal malformations are the primary etiology for bilateral VFP.
- Neoplastic and central nervous system lesions are key causes of right-sided VFP, with poor prognosis for bilateral and right-sided VFP.
Abstract:
Objective: To investigate the etiology and clinical characteristics of vocal fold paralysis in children. To provide useful information for diagnosis, management and prognosis in the clinical work. Methods: Two hundred and seven children with vocal fold paralysis in Children's Hospital of Fudan University were retrospectively studied, and followed-up. Results: All the patients had hoarseness.151 cases had vocal paralysis in the left side and the main etiology was pulmonary arterial hypertension.43 cases had bilateral vocal paralysis and all of them had respiratory problems.The main etiology were congenital tracheoesophageal malformations.13 cases had vocal paralysis in the right side.In terms of etiology, 8 cases were related to intracranial lesions, 2 cases were idiopathic. Conclusions: The main etiologies of left vocal fold paralysis were cardiovascular diseases, and bilateral vocal paralysis were congenital tracheoesophageal malformations.The main etiologies of right vocal fold paralysis were neoplastic and central lesion.The prognosis of bilateral vocal fold paralysis and right vocal fold paralysis was poor.
