“…Their word identification scores changed due to their chronological age, duration of ABI use, and cognitive development. Results of speech recognition skills are also similar to those of other studies [14,[16][17][18][19] . Open-set sentence recognition is improved in 12 of the children.…”

“…All children used their ABI regularly on a daily basis, and similar to the findings in the literature, they were found to develop awareness toward environmental sounds and speech sounds after 1-month to 3-month intervals [11][12][13][14] . Functionality of auditory perception skills was mostly evaluated with MAIS/IT-MAIS in researches; however, in our research, FAPCI was conducted to determine auditory functioning and compared with normally hearing population.…”

“…These children scored more than 50%, and three children communicated via telephone. Sanna et al [14] reported a 12-yearold girl with ossified cochlea who had improved open-set sentence recognition with lip-reading. Also, Colletti and Shannon [16] notified the results of 20 ABI users; according to their findings, 65% of the non-tumor patients had improved open-set speech perception skills.…”

OBJECTIVE:The aim of this study is to describe the rehabilitative outcomes of pediatric auditory brainstem implant (ABI) users in the Department of Otolaryngology in the Hacettepe University. It was a retrospective study, and all patients' files were reviewed. MATERIALS and METHODS:The data was collected from 41 children who were fitted with ABI between 2005 and 2013. Inclusion criteria for children in our study are profound, congenital bilateral sensory-neural hearing loss with anomalies (such as cochlear, labyrinthine, and cochlear nerve aplasia) and more than one year of auditory experience with ABI. Post-meningitis patients and neurofibromatosis type 2 (NF2) patients were excluded. Auditory perception was evaluated using the Meaningful Auditory Integration Scale (MAIS), Functioning after Pediatric Cochlear Implantation (FAPCI) instrument, Categories of Auditory Performance (CAP), and Children's Auditory Perception Skills Test in Turkish (CIAT). Speech intelligibility was categorized with speech intelligibility rating (SIR), and language development was assessed using the Test of Early Language Development-Third Edition (TELD-3) and Manchester Spoken Language Development Scale (MSLD). RESULTS:All patients gained basic audiological functions and were able to recognize and discriminate sounds by the third month of ABI surgery. According to the duration of ABI use and learning skills, patients revealed development from word identification to sentence recognition level in a wide spectrum. CONCLUSION:Preliminary results indicate that all children have gained basic auditory perception skills. On the other hand, language and speech development data were varying among children. Additional handicaps seemed to slow down progression. Secondary improvement was seen at psychosocial areas with respect to behavioral and social adjustment as well as eagerness to start communication.

“…In our sample, the presence of hearing thresholds corresponding to mild hearing loss and even normal thresholds in some frequencies suggest the patients were able to perceive many sounds in the environment, including high frequencies, showing that the ability to perceive environment sounds and perform speech recognition assisted by lip reading can be restored with this type of implant 8,9 . Although the outcomes provided by the auditory brainstem implants were compared against those of one-channel cochlear implants 10 , the early free field audiometry test results were positively surprising, mainly in terms of patient compliance and daily use of the hearing aid.…”

Audi tory Brainstem Implants were developed to partially restore the hearing capabilities of patients without cochlear nerves bilaterally. Aim: this paper aims to discuss the clinical and surgical findings of four ABI patients. Materials and method: four patients diagnosed with bilateral schwannomas received auditory brainstem implants (ABI) and had one of their tumors resected in the same surgical procedure. Clinical aspects, surgical technique, anatomic landmarks, and outcomes were analyzed. Results: the anatomic landmarks were identified in all four patients in relation to the foramina of Luschka. Two patients had CSF leaks. The electrodes were well positioned and hearing sensation was good enough to allow for sound recognition and assist patients perform lip reading. Conclusion: the outcomes observed in our patients were quite encouraging and offer great perspectives for those suffering from deep bilateral deafness and impaired central auditory pathways.Keywords: surgery, auditory brain stem implantation, neurofibromatosis type 2, results.original article Rev Bras Otorrinolaringol 2008;74(5):647-51.

“…Functional results show great variability; from noise perception only to useful speech discrimination in audiovisual mode in a few patients so far. Since the early trials by Hitselberger and House in 1979, as reported by Edgerton et al 13 and Hit sel berger et al, 21 profound improvements in implant array, technology, and speech processing strategies 65 have brought about useful improvement in functional outcome, 4,8,9,17,23,29,31,32,37,42,43,45,46,48,58,59 but still results remain less favorable than in cochlear implants or auditory brainstem implants (ABIs) in patients without NF2. 8 Visionindependent speech perception is not generally achieved.…”

Object Patients with bilateral auditory nerve destruction may perceive some auditory input with auditory brainstem implants (ABIs). Despite technological developments and trials in new stimulation sites, hearing is very variable and of limited quality. The goal of this study was to identify advantageous and critical factors that influence the quality of auditory function, especially speech perception. Methods The authors conducted a prospective study on ABI operations performed with the aid of multimodality neuromonitoring between 2005 and 2009 in 18 patients with neurofibromatosis Type 2. Outcome was evaluated by testing word recognition (monotrochee-polysyllabic word test at auditory-only mode [MTPa]) and open speech perception (Hochmair-Schulz-Moser [HSM] sentence test), both in pure auditory mode. The primary outcome was the HSM score at 24 months. The predictive meaning of general clinical data, tumor volume, number of active electrodes, duration of deafness, and early hearing data was examined. Results In 16 successful ABI activations the average score for MTPa was 89% (SD 13%), and for HSM it was 41% (SD 32%) at 24 months. There were 2 nonresponders, 1 after radiosurgery and the other in an anatomical variant. Direct facial nerve reconstruction during the same surgery was followed by successful nerve recovery in 2 patients, with a simultaneous very good HSM result. Patients' age, tumor extension, and tumor volume were not negative predictors. There was an inverse relationship between HSM scores and deafness duration; 50% or higher HSM scores were found only in patients with ipsilateral deafness duration up to 24 months. The higher the deafness sum of both sides, the less likely that any HSM score will be achieved (p = 0.034). In patients with total deafness duration of less than 240 months, higher numbers of active electrodes were significantly associated with better outcomes. The strongest cross-correlation was identified between early MTPa score at 3 months and 24-month HSM outcome. Conclusions This study documents that open-set speech recognition in pure auditory mode is feasible in patients with ABIs. Large tumor volumes do not prevent good outcome. Positive preconditions are short ipsilateral and short bilateral deafness periods and high number of auditory electrodes. Early ability in pure auditory word recognition tests indicates long-term capability of open speech perception.
