Abstract (original English)

Objective To present a child with cochlear nerve deficiency (CND) who received simultaneous bilateral simultaneous auditory brainstem implants (BS-ABI) and subsequently presented with bilateral cerebrospinal fluid (CSF) leaks unresponsive to standard treatments. To propose a novel rigid retrosigmoid cranioplasty for treating and preventing CSF leaks in children at high risk for this complication. Patient A 3.5-year-old child with CND, vertebral defects, anal atresia, cardiac defects, tracheo-esophageal fistula, renal anomalies, and limb abnormalities, coloboma, heart defect, atresia choanae, retarded growth and development, genital abnormality, and ear abnormality, Arnold Chiari malformation, previous treated tracheo-esophageal fistula underwent BS-ABI. Postoperatively, the child had recurrent bilateral retroauricular fluid collections. A standard revision procedure revealed breaches in the dural closure, migration of the auditory brainstem implantation (ABI) receiver stimulator on both sides and was unsuccessful in stopping the leak. Interventions Bilateral repair with free fat grafting filling the craniectomy space and two absorbable meshes of poly-L-D-lactic (PLDL) acid stabilized with PLDL pins on the surrounding cranium, one to stabilize the fat graft and one to fix the ABI receiver stimulators inside the subperiosteal pockets. Main outcome measure CSF leak recurrence, pos
