AbstractObjective:We report the case of a successful cochlear implantation in a patient with severe cochlear hypoplasia.Case report:The outcome of cochlear implantation is generally less favourable for patients with cochlear hypoplasia than for those with a normal cochlear structure. In the reported patient, part of the electrode array was inserted into the internal auditory canal. Nevertheless, the benefits following cochlear implantation seemed to outweigh the risks for this patient.Conclusion:Cochlear hypoplasia is not necessarily a contraindication for cochlear implantation.

AbstractObjective:To report a series of pitfalls and complications in a case of cochlear implantation.Method:Case report.Results:An 11-year-old boy affected by auditory neuropathy underwent cochlear implantation. Intra-operative assessment was apparently consistent with correct insertion of the electrode array into the cochlea. However, subsequent high resolution computed tomography revealed that the entire electrode array was curled up within the vestibule. Revision surgery was complicated by cerebrospinal fluid leakage. A straight probe was repeatedly inserted into the internal auditory canal, before conversion to a canal wall down procedure and appropriate positioning of the electrode array.Conclusion:In this case, mild anteriorisation of the facial nerve created an awkward insertion angle for the electrode array via the retro-facial route, which may have triggered the described series of adverse events.

Cavernous haemangiomas are rare lesions of the cerebello-pontine angle that can mimic the more commonly occurring vestibular schwannoma. A case report involving a patient with a cavernous haemangioma of the internal auditory canal (IAC) highlights this as a diagnostic possibility for lesions of the IAC by comparing and contrasting the clinical and radiological findings with the more commonly occurring vestibular nerve and facial schwannomas.Symptoms such as hearing loss and facial paralysis that are disproportionate to the size of the lesion or fluctuate with hormonal changes such as those seen in pregnancy are suggestive of haemangioma. Radiological imaging demonstrating a lesion enchancing with gadolinium and containing areas of calcification is also suggestive of haemangioma. It is important to consider the possible diagnosis of haemangioma as early recognition of this entity may improve the chances of preserving the functional integrity of the facial nerve.
