Objectives Here we present the audiometric outcomes of patients undergoing vestibular schwannoma resection and cochlear implantation. We additionally reviewed preoperative audiometric and radiological data, with the aim of developing a new scoring system to identify suitable patients for this treatment course. Methods After translabyrinthine vestibular schwannoma resection, cochlear nerve conduction was evaluated using intraoperative electrically evoked brain stem response audiometry. Patients with positive results received a cochlear implant. We evaluated the preoperative audiometric results, and vestibular schwannoma size and extension, to develop a new scoring system to identify patients with higher likelihood of nerve integrity after tumor removal and subsequent cochlear implantation. Results Seventeen patients with unilateral sporadic vestibular schwannomas underwent translabyrinthine resection, of whom ten received a cochlear implant. Ten patients are daily cochlear implant users. The mean word recognition score ss 28% at 65 dB, and 52% at 80 dB. Nine of the ten patients have open-set speech understanding. All patients whose vestibular schwannoma did not make contact with the modiolus were able to receive a cochlear implant, compared to none of the patients with modiolus infiltration. Tumor size alone did not predict the probability of sparing the cochlear nerve. Conclusions Simultaneous translabyrinthine vestibular schwannoma excision and cochlear implantation based on intraoperative electrically evoked brain stem response audiometry measurements is a good option for hearing rehabilitation. Preoperative exact assessment of the vestibular schwannoma extension, audiometric testing, and promontory stimulation electrically evoked brain stem response audiometry could improve preoperative patient selection and predict the possibility of cochlear implantation.

Hearing Outcomes

Objectives: Historically, eventual loss of cochlear nerve function has limited patients with neurofibromatosis type 2 (NF2) to auditory brainstem implants (ABI), which in general are less effective than modern cochlear implants (CI). Our objective is to evaluate hearing outcomes following ipsilateral cochlear implantation in patients with NF2 and irradiated vestibular schwannomas (VS), and sporadic VS that have been irradiated or observed. Methods: Multi-center retrospective analysis of ipsilateral cochlear implantation in the presence of observed and irradiated VS. MESH search in NCBI PubMed database between 1992 and 2019 for reported cases of cochlear implantation with unresected vestibular schwannoma. Results: Seven patients underwent ipsilateral cochlear implantation in the presence of observed or irradiated vestibular schwannomas. Four patients had sporadic tumors with severe-profound contralateral hearing loss caused by presbycusis/hereditary sensorineural hearing loss, and three patients with NF2 lost contralateral hearing after prior surgical resection. Prior to implantation, one VS was observed without growth for a period of 7 years and the others were treated with radiotherapy. Mean post-operative sentence score was 63.9% (range 48-91) at an average of 28 (range 2-84) months follow up. All patients in this cohort obtained open set speech perception. While analysis of the literature is limited by heterogenous data reporting, 85% of implants with observed schwannomas achieved some open set perception, and 67% of patients previously radiated schwannomas. Furthermore, blending literature outcomes for post implantation sentence testing in quiet without lip-reading show 59.0 ± 35% for patients with CI and observed tumors and 55.7 ± 35% for patients with radiated tumors, with both groups ranging 0 to 100%. Conclusion: This retrospective series and literature review highlight that hearing outcomes with CI for VS patients are superior to those achieved with ABI. However, important considerations including imaging, delayed hearing loss, and observation time cannot be ignored in this population.

Cochlear implantation (CI) has become an option for the treatment of hearing loss after translabyrinthine resection of vestibular schwannomas. The surgical video presents the case of a 67-year-old male who had translabyrinthine resection of vestibular schwannoma with simultaneous CI and closure with a hydroxyapatite (HA) cement cranioplasty. HA cement cranioplasty can be utilized in place of abdominal fat graft for the closure of translabyrinthine approaches with similar efficacy and complication profile. To the authors’ knowledge, this is the first reported case of a simultaneous CI and translabyrinthine resection of vestibular schwannoma with HA cement cranioplasty.

This study examines the assumptions underlying the scoring system of the Arizona Articulation Proficiency Scale: Revised. Twenty-one children between the ages of four years two months and six years 11 months were administered the Arizona Articulation Proficiency Scale: Revised and the Screening Deep Test of Articulation. The subjects' performance on the two tests was compared for the phones: [s], [l], [r], [t∫], [θ], [∫], [k], [f], and [t]. Results suggested that 1) the production of most sounds in only two contexts does not necessarily reflect the accuracy of production of those sounds in other contexts, and 2) for the sounds tested, the weightings assigned on the basis of their frequency of occurrence rather than the frequency with which they were misarticulated overestimated the extent of many articulation errors.
