Upper airway obstruction in children with Down syndrome

Area of Science:

• Pediatric Otolaryngology
• Genetics and Rare Diseases
• Respiratory Medicine

Background:

• Children with Down syndrome (DS) frequently present with upper airway obstruction (UAO).
• The multifactorial nature of UAO in DS poses significant management challenges.
• Understanding surgical outcomes is crucial for improving care in this population.

Purpose of the Study:

• To analyze the complex causes of upper airway obstruction (UAO) in children with Down syndrome.
• To evaluate the effectiveness of surgical interventions for UAO in this patient group.
• To identify factors associated with surgical outcomes in pediatric Down syndrome patients with UAO.

Main Methods:

• Retrospective chart review of 71 pediatric patients with Down syndrome and UAO over a 5-year period.
• Analysis of diverse obstructive problems including lymphoid hyperplasia, macroglossia, and stenosis.
• Surgical interventions ranged from tonsillectomy to tracheotomy, with outcomes assessed postoperatively.

Main Results:

• Of 55 surgical patients, 27 with mild symptoms improved significantly after tonsil/adenoid surgery.
• A subgroup of younger patients with severe, multifocal obstruction and cardiac disease experienced residual symptoms (39%) and tracheotomy dependence (4/28).
• Five deaths occurred, with three attributed to airway complications.

Conclusions:

• Upper airway obstruction in children with Down syndrome is often complex and multifocal.
• Significant residual symptoms post-surgery are common, highlighting the need for comprehensive evaluation.
• An individualized, multidisciplinary approach is essential for managing UAO in pediatric Down syndrome patients.
