Pediatric Otology and Neurotology
Hearing as a developmental emergency
In the first years of life, hearing loss is a time-sensitive problem because of language acquisition. Know the newborn hearing screening pathway: failed screen → rescreen → diagnostic ABR → intervention by 6 months. Distinguish conductive from sensorineural and know that otitis media with effusion is the most common cause of conductive loss in children. Tympanostomy tube indications: chronic OME with hearing loss, recurrent acute otitis media meeting criteria, and complications of AOM.
Concepts to master
Congenital hearing loss workup: genetics (GJB2, connexin 26), CMV testing, imaging (CT/MRI for cochlear anatomy, enlarged vestibular aqueduct), and ophthalmology/ECG for syndromes (Usher, Jervell-Lange Nielsen, Waardenburg). Cholesteatoma in children is more aggressive and recurrent than in adults; suspect with persistent otorrhea, retraction pocket, or conductive loss. Understand cochlear implant candidacy and the importance of early implantation for language outcomes. Vestibular complaints in children are underrecognized - migraine-associated vertigo is common; BPPV is less common than in adults. Facial nerve paralysis with otitis requires urgent evaluation.
Traps
Do not treat OME with antibiotics routinely; watchful waiting is appropriate for most. A child with a draining ear and a tube is not automatically infected - consider granulation or tube malfunction. Beware missing cholesteatoma behind a seemingly simple effusion. Also, an abnormal ABR in a child with a normal ear exam still requires full workup; do not assume it is transient.
Rule of thumb
Any child with persistent OME beyond 3 months with hearing loss or language delay is a tube candidate; otherwise observe and reassess.
Worked example
A 2-year-old with bilateral OME for 4 months, 30 dB conductive loss, and delayed expressive language: tympanostomy tubes are indicated because the effusion is chronic and there is documented impact on hearing/language.
