A transpetrosal approach allowed cochlear sensor implantation to detect residual hearing. An enlarged retrosigmoid approach then allowed subtotal microsurgical removal of the lesion; consequently, the authors illustrate the technical nuances of an auditory brainstem implant (ABI). One month after surgery, the ABI was successfully switched on, giving back hearing perception to the patient.<\/jats:p>\n \n The video can be found here:\n https:\/\/stream.cadmore.media\/r10.3171\/2021.7.FOCVID2188<\/jats:ext-link>\n <\/jats:p>","DOI":"10.3171\/2021.7.focvid2188","type":"journal-article","created":{"date-parts":[[2021,10,1]],"date-time":"2021-10-01T09:30:03Z","timestamp":1633080603000},"page":"V16","source":"Crossref","is-referenced-by-count":1,"title":["Removal of Koos IV acoustic neuroma and auditory brainstem implant in NF2 patient"],"prefix":"10.3171","volume":"5","author":[{"given":"Maria Rosaria","family":"Scala","sequence":"first","affiliation":[{"name":"Department of Pediatric Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pietro","family":"Spennato","sequence":"additional","affiliation":[{"name":"Department of Pediatric Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio Della","family":"Volpe","sequence":"additional","affiliation":[{"name":"Otology and Cochlear Implant Unit, Santobono-Pausilipon Children\u2019s Hospital, Naples;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Santoro","sequence":"additional","affiliation":[{"name":"Neurofibromatosis Referral Centre, Department of Woman, Child and General and Specialized Surgery, University of Campania \u201cLuigi Vanvitelli,\u201d Naples; and"},{"name":"Departments of Physical and Mental Health, and Preventive Medicine, University of Campania \u201cLuigi Vanvitelli,\u201d Naples, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefania","family":"Picariello","sequence":"additional","affiliation":[{"name":"Neurofibromatosis Referral Centre, Department of Woman, Child and General and Specialized Surgery, University of Campania \u201cLuigi Vanvitelli,\u201d Naples; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alfonso Maria","family":"Varricchio","sequence":"additional","affiliation":[{"name":"Otology and Cochlear Implant Unit, Santobono-Pausilipon Children\u2019s Hospital, Naples;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Ruggiero","sequence":"additional","affiliation":[{"name":"Department of Pediatric Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serena","family":"d\u00e9 Santi","sequence":"additional","affiliation":[{"name":"Department of Pediatric Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Cinalli","sequence":"additional","affiliation":[{"name":"Department of Pediatric Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"5","key":"b1","series-title":"Pediatr Blood Cancer","doi-asserted-by":"publisher","first-page":"e28228","DOI":"10.1002\/pbc.28228","article-title":"Bevacizumab for NF2-associated vestibular schwannomas of childhood and adolescence","volume":"67","author":"Renzi S","year":"2020","unstructured":"Renzi S, Michaeli O, Salvador H, Bevacizumab for NF2-associated vestibular schwannomas of childhood and adolescence.
