Inner ear malformations (IEMs) present significant challenges for cochlear implantation (CI), particularly the common cavity deformity, in which the cochlea and vestibule merge into a single space. Surgical and audiological outcomes in such cases depend on accurate electrode placement, nerve integrity, and tailored surgical strategies....

This single case report documents a feasible surgical strategy for bilateral CI in common cavity deformity; not practice-changing but useful as a reference technique for rare complex cases.
Common cavity deformity is among the most challenging inner ear malformations for cochlear implantation, and documented bilateral implantation strategies using custom electrodes are scarce, making this case a small but meaningful addition to the surgical literature.
- 01Pediatric patient with common cavity inner ear deformity received sequential bilateral cochlear implants.
- 02Transmastoid labyrinthotomy approach was used instead of the conventional cochleostomy route.
- 03Custom-made electrode arrays were required due to the abnormal inner ear anatomy.
- 04Case report level evidence; findings cannot be generalized beyond this single patient.
- 05Demonstrates proof-of-concept for bilateral implantation in severe cochlear malformation.
Sequential bilateral cochlear implantation via transmastoid labyrinthotomy with custom electrodes is feasible in a pediatric patient with common cavity deformity.
