Objective: Rudimentary otocyst (RO) is characterized by an otic capsule without an internal auditory canal, which is considered a contraindication to cochlear implantation (CI). In this study, we were the first to report two patients with ROs who underwent CI.
Patient: Two patients (18 months old and 2 years old) presenting with bilateral congenital hearing loss were diagnosed with ROs.
Intervention: CI was performed. The transmastoid slotted labyrinthotomy approach was used with customized MED-EL electrode arrays.
Main Outcome Measures: Categorical auditory performance, infant-toddler meaningful auditory integration of sound, the speech intelligibility rating, and meaningful use of speech scale.
Results: Both children could understand common phrases and had intelligible, connected speech 2 years after CI.
Conclusion: With proper indication, surgical approach and postoperative training, a child with an RO may benefit from CI.
