Summary
Mondini dysplasia can cause cerebrospinal fluid (CSF) otorrhea and recurrent meningitis in infants. Early diagnosis and surgical intervention, though with a 30% failure rate, improve outcomes and hearing habilitation.
Area of Science:
- Otolaryngology
- Pediatric Neurology
- Developmental Biology
Background:
- Mondini dysplasia is a congenital inner ear malformation.
- It is associated with cerebrospinal fluid (CSF) otorrhea and recurrent meningitis.
- Understanding its embryologic basis is crucial for diagnosis and management.
Observation:
- Three infants with this association were treated at Baylor College of Medicine.
- Thirty-nine similar cases have been previously reported.
- Clinical evaluation involves assessing recurrent meningitis and hearing impairment.
Findings:
- Brain-stem response audiometry and thin-cut computed tomography (CT) of temporal bones are key diagnostic tools.
- Surgical management, often involving stapedectomy and vestibule obliteration, depends on the ear's functional status.
- A 30% surgical failure rate exists after a single procedure.
Implications:
- Early identification and prompt surgical management of Mondini dysplasia reduce infant morbidity and mortality.
- Timely intervention facilitates early habilitation for children with congenital hearing impairment.
- This condition underscores the importance of a multidisciplinary approach in pediatric neuro-otology.
