Insights
Obstructive sleep apnea syndrome (OSAS) in children often has unusual causes beyond tonsilar hypertrophy. Identifying these rare etiologies is crucial for effective, individualized treatment.
Area of Science:
- Pediatrics
- Otolaryngology
- Sleep Medicine
Background:
- Obstructive sleep apnea syndrome (OSAS) is a prevalent chronic condition in children characterized by airway obstruction.
- While tonsillar hypertrophy is the most common cause, approximately 20% of pediatric OSAS cases involve other underlying factors.
Observation:
- This paper highlights two pediatric cases of OSAS with uncommon etiologies: respiratory dystonia and supraglottic stenosis.
- These cases underscore that OSAS can arise from diverse structural and neuromotor issues beyond adenotonsillar enlargement.
Findings:
- Adenotonsillectomy is the standard treatment, but it may not address the root cause in all pediatric OSAS patients.
- Detailed etiological investigation by Ear, Nose, and Throat (ENT) specialists is essential for accurate diagnosis.
Implications:
- Individualized treatment plans based on specific etiologies are necessary for optimal outcomes in pediatric OSAS.
- Recognizing less common causes of OSAS can improve diagnostic accuracy and therapeutic success in affected children.
Abstract:
Obstructive sleep apnea syndrome is a chronic condition of airway obstruction, common in children, with known clinical consequences. The etiology of OSAS in children stems from a combination of obstructing structural factors and neuromotor factors. In children, tonsilar hypertrophy accounts for this condition in most cases, however, in about 20% of the cases, other causes are involved. For the treatment of apnea in children, adenotonsillectomy is the most commonly performed procedure, though we should indicate the treatment according to its underlying cause. The aim of this paper is to highlight other possible apnea etiologies, contributing to appropriate diagnosis and treatment. We present two cases of patients with apnea of unusual origin: one of respiratory dystonia and another of supraglottic stenosis as the causative factor of obstructive sleep apnea. In conclusion, we emphasize the need for the ENT to perform detailed research on the etiology of apnea, for individualized treatment.

Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
