Diagnostic Considerations

The diagnosis of Mondini deformity is confirmed with radiographs that demonstrate a cystic cochlear apex, minimal dilation of the vestibule, and an enlarged vestibular aqueduct. While most patients with congenital sensorineural hearing loss have incomplete partitioning, other etiologies to consider include the following:

  • Labyrinthine aplasia

  • Cochlear aplasia

  • Common cavity

  • Other types of Incomplete partitioning

  • Cochlear hypoplasia
