Question 1: What is the most common cause of conductive hearing loss in children?
- Otosclerosis
- Otitis media with effusion (glue ear) (Correct answer)
- Cholesteatoma
- Presbycusis
Correct answer: Otitis media with effusion (glue ear)
Otitis media with effusion ('glue ear') is the leading cause of conductive hearing loss in pediatric patients due to Eustachian tube dysfunction.
Question 2: According to EHDI/JCIH guidelines, by what age should newborn hearing screening be completed in the US?
- 3 months
- 6 months
- 1 month (before hospital discharge) (Correct answer)
- 12 months

- Usher syndrome
- Pendred syndrome (Correct answer)
- Waardenburg syndrome
- Branchio-oto-renal syndrome
Correct answer: Pendred syndrome
Pendred syndrome is an autosomal recessive disorder caused by SLC26A4 mutations, presenting with sensorineural hearing loss and thyroid goiter with normal vestibular function.
