Otorhinologic Disorders in 22q11.2 Deletion Syndrome

Area of Science:

• Genetics
• Otolaryngology
• Immunology

Background:

• 22q11.2 deletion syndrome is associated with various health issues.
• Otologic and sinonasal diseases are common but not well-characterized in this population.
• Understanding these conditions is crucial for timely diagnosis and management.

Purpose of the Study:

• To investigate the incidence and natural history of otologic and sinonasal diseases in children with 22q11.2 deletion syndrome.
• To identify common pathogens and surgical interventions for these conditions.
• To explore potential links with immunodeficiency.

Main Methods:

• Retrospective case series of children diagnosed with 22q11.2 deletion syndrome (including DiGeorge and velocardiofacial syndromes).
• Review of medical records for otologic/rhinologic diagnoses, surgeries, and laboratory findings.
• Analysis of 128 patients meeting inclusion criteria.

Main Results:

• High incidence of recurrent acute otitis media (42.2%) and chronic otitis media with effusion (28.9%).
• Significant rates of tympanostomy tube placement (38.3%) and adenoidectomy (29.7%).
• Methicillin-resistant Staphylococcus aureus and Streptococcus pneumoniae were common pathogens.

Conclusions:

• Otologic disease affects about half of children with 22q11.2 deletion syndrome, frequently needing surgery.
• Immunodeficiency did not correlate with increased risk of otologic/sinonasal disease in this cohort.
• Further research with larger cohorts is needed to explore immunodeficiency's role.
