OBJECTIVES: Inner ear malformations, particularly incomplete partition type I, are well-recognised risk factors for cerebrospinal fluid leakage, which may result in recurrent meningitis.
METHODS: We present a case series of three paediatric patients with incomplete partition type I malformation who experienced an intra-operative cerebrospinal fluid 'gusher' during cochlear implantation and subsequently developed meningitis due to contralateral cerebrospinal fluid leakage from a stapes footplate fistula. Detailed clinical assessments, radiological findings and surgical management are described.
RESULTS: In all three cases, the initial suspicion of a cerebrospinal fluid fistula was directed towards the implanted ear. However, radiological evaluation and intra-operative findings confirmed a stapes footplate fistula in the non-implanted ear. Surgical closure was achieved using temporal fascia and fibrin glue. In one case, subtotal petrosectomy was required because of persistent cerebrospinal fluid leakage.
CONCLUSION: In patients with incomplete partition type I malformations undergoing cochlear implantation, contralateral cerebrospinal fluid fistula should be considered in the differential diagnosis of post-operative meningitis.
