Unilateral common cavity deformity: Recurrent meningitis due to insufficient newborn hearing screening

Area of Science:

• Otolaryngology
• Pediatric Infectious Diseases
• Medical Diagnostics

Background:

• Newborn hearing screening protocols may miss unilateral hearing loss, delaying diagnosis of underlying pathologies.
• Undetected hearing impairment can increase the risk of severe infections, particularly in infants.
• Common cavity deformity is a congenital inner ear malformation that can lead to hearing loss.

Observation:

• A case of recurrent Streptococcus pneumoniae meningitis in an infant with unilateral common cavity deformity is presented.
• The infant's left ear hearing loss was diagnosed late due to inadequate newborn hearing screening.
• The underlying pathology was confirmed only after the second episode of meningitis.

Findings:

• Delayed diagnosis of unilateral hearing loss, associated with common cavity deformity, contributed to recurrent meningitis.
• Surgical intervention (subtotal petrosectomy) was unsuccessful and led to a subsequent meningitis episode.
• The case underscores the link between congenital cochlear malformations, hearing loss, and infectious risks.

Implications:

• Emphasizes the critical need for comprehensive newborn hearing screening to identify all cases of hearing impairment.
• Highlights the importance of accurate diagnosis and appropriate management of cochlear malformations to prevent serious complications.
• Stresses the necessity of refined surgical techniques for treating inner ear malformations to avoid adverse outcomes.
