ABSTRACT: OBJECTIVE: To evaluate the effects of otitis media with effusion on surgical parameters, patient safety, perioperative and postoperative complications. METHODS: Total 890 children who underwent cochlear implantation between 2006 and 2015 were included. The ages ranged from 12 months to 63 months (mean: 32 months). The patients were divided into two groups according to the presence or absence of otitis media with effusion; otitis media with effusion group and non-otitis media group. RESULTS: Of 890 children, 105 had otitis media with effusion prior to surgery. In non-otitis media with group, there were 785 children. The average duration of surgery was 60min (ranged from 28 to 75min) in non-otitis media group, and 90min (ranged from 50 to 135min) in otitis media with effusion group (p<0.05). Granulation tissue and edematous middle ear and mastoid mucosa were observed in all cases of otitis media with effusion during the surgery. There was no significant difference between the complications of groups with or without otitis media with effusion (p>0.05). In 5 of 105 patients, there was a ventilation tube inserted before cochlear implantation, which did not change the outcome of implantation. CONCLUSION: There is no need for surgical treatment for otitis media with effusion before implantation since otitis media with effusion does not increase the risks associated with cochlear implantation. Operation duration is longer in the presence of otitis media with effusion. However, otitis media with effusion leads to intraoperative difficulties like longer operation duration, bleeding, visualization of the round window membrane, cleansing the middle ear granulations as well as mastoid and petrous air cells.

2 Article Recovery of Tinnitus and Sensorineural Hearing Loss Due to Lysis of Arachnoid Adhesions in the Posterior Cranial Fossa: Is There a Novel Etiology in Neurotological Disorders? 2017

Cevizci, Raşit / Dilci, Alper / Tekin, Ahmet Mahmut / Bayazıt, Yıldırım. ·Clinic of Ear Nose Throat and Head Neck Surgery, İstanbul Medipol University, İstanbul, Turkey. alperdilci@yahoo.com. ·J Int Adv Otol · Pubmed #28816700.

ABSTRACT: We reported the recovery of sensorineural hearing loss and tinnitus in a 22-year-old man after complete removal of intracranial portion of jugular foramen schwannoma via the retrosigmoid approach. The aim of this case report was to present the excision of a large jugular foramen schwannoma via the retrosigmoid approach and to describe the improvement of sensorineural hearing loss related to arachnoid inflammations due to chronic arachnoiditis after suboccipital craniectomy. The recovery of sensorineural hearing loss and tinnitus after release of arachnoid adhesions may indicate the clinical significance of these adhesions or arachnoiditis, which should also be considered and investigated in the etiology of other neurotological diseases.

4 Article Comparison of Carina active middle-ear implant with conventional hearing aids for mixed hearing loss. 2016

Savaş, V A / Gündüz, B / Karamert, R / Cevizci, R / Düzlü, M / Tutar, H / Bayazit, Y A. ·ENT Clinic,Silvan State Hospital,Diyarbakır,Ankara,Turkey. · Department of Audiology,Faculty of Medicine,Gazi University,Ankara,Turkey. · Department of Otolaryngology,Faculty of Medicine,Gazi University,Ankara,Turkey. · Department of Otolaryngology,Faculty of Medicine,Medipol University,Istanbul,Turkey. ·J Laryngol Otol · Pubmed #26991874.

ABSTRACT: OBJECTIVE: To compare the auditory outcomes of Carina middle-ear implants with those of conventional hearing aids in patients with moderate-to-severe mixed hearing loss. METHODS: The study comprised nine patients (six males, three females) who underwent middle-ear implantation with Carina fully implantable active middle-ear implants to treat bilateral moderate-to-severe mixed hearing loss. The patients initially used conventional hearing aids and subsequently received the Carina implants. The hearing thresholds with implants and hearing aids were compared. RESULTS: There were no significant differences between: the pre-operative and post-operative air and bone conduction thresholds (p > 0.05), the thresholds with hearing aids and Carina implants (p > 0.05), or the pre-operative (mean, 72.8 ± 19 per cent) and post-operative (mean, 69.9 ± 24 per cent) speech discrimination scores (p > 0.05). One of the patients suffered total sensorineural hearing loss three months following implantation despite an initial 38 dB functional gain. All except one patient showed clinical improvements after implantation according to quality of life questionnaire (Glasgow Benefit Inventory) scores. CONCLUSION: Acceptance of Carina implants is better than with conventional hearing aids in patients with mixed hearing loss, although both yield similar hearing amplification. Cosmetic reasons appear to be critical for patient acceptance.

5 Article Management of children with auditory neuropathy spectrum disorder (ANSD). 2016

Gökdoğan, Çağıl / Altınyay, Şenay / Gündüz, Bülent / Kemaloğlu, Yusuf Kemal / Bayazıt, Yıldırım / Uygur, Kemal. ·Gazi University Hospital, Department of Audiology, Ankara, Turkey. Electronic address: cagilgokdogan@gmail.com. · Gazi University Hospital, Department of Audiology, Ankara, Turkey. · Gazi University Hospital, Department of ENT-HNS, Ankara, Turkey. ·Braz J Otorhinolaryngol · Pubmed #26781981.

ABSTRACT: INTRODUCTION: ANSD is a challenging problem. OBJECTIVE: To present our experience on management of the children with ANSD with respect to clinical data. METHODS: This retrospective study included all children younger than 16 years of age who applied to the department between 2005 and 2013 (with the exception of newborn hearing screening NHS referrals). The data were derived from pure tone, OAEs and ABR tests, and further medical risk factors of the subjects were evaluated. RESULTS: ANSD was recognized in 74 ears of 40 children (B/U: 34/6) among 1952 children with SNHL (2.04%) detected among 9520 applicants to the department (0.42%). The clinical tests revealed that hearing loss greater than 15dB was present in both ears of 38 cases. The degree of hearing loss was profound in 48% children, severe in 12% children, moderate in 28% children, mild in 10% children and normal in 5% children. ABRs were absent/abnormal in 37/3 ears and CMs were detected in all. Acoustic reflexes were absent in all ears. Rehabilitation was managed by CI and hearing aids in 15 and 23 cases, respectively. FM system was given to two cases displaying normal hearing but poor speech discrimination in noisy environments. CONCLUSION: ANSD is a relatively challenging problem for the audiology departments because of its various clinical features and difficulties in management. Our patients with ANSD most commonly displayed profound hearing loss. The number of overlooked cases may be minimized by performing ABR and OAE in every case referred with the suspicion of hearing loss.

6 Article Auditory brainstem implant in postlingual postmeningitic patients. 2016

Bayazit, Yildirim / Kosaner, Julie / Celenk, Fatih / Somdas, Mehmet / Yilmaz, Ismail / Altin, Gokhan / Cevizci, Rasit / Yavuz, Haluk / Ozluoglu, Levent. ·Department of Otorhinolaryngology, Medipol University Faculty of Medicine, Istanbul, Turkey. · MEDers Speech and Hearing, Istanbul, Turkey. · Department of Otorhinolaryngology, Faculty of Medicine, Gaziantep University, Gaziantep, Turkey. · Department of Otorhinolaryngology, Faculty of Medicine, Erciyes University, Kayseri, Turkey. · Department of Otorhinolaryngology, Faculty of Medicine, Baskent University, Adana, Turkey. · Department of Otorhinolaryngology, Faculty of Medicine, Baskent University, Ankara, Turkey. ·Laryngoscope · Pubmed #26485185.

ABSTRACT: OBJECTIVES/HYPOTHESIS: The aim of this study was to evaluate outcomes of postlingual postmeningitic patients who received an auditory brainstem implant (ABI). STUDY DESIGN: Retrospective analysis was performed on postlingual postmeningitic patients with bilateral profound sensorineural hearing loss who underwent ABI between the years 2007 and 2014 METHODS: All patients were postlingually deaf due to cochlear ossification as a consequence of bacterial meningitis. The patients received a MED-EL or Neurelec ABI. All patients were operated on at different hospitals by the same primary surgeon. The patients were tested using Ling 5 sound detection, sound field implant thresholds between 250 Hz and 6 kHz, and 6 to 12 choice closed-set word and sentence tests. RESULTS: Nine patients with postmeningitic cochlear ossification received an ABI. Five of nine ABI users (55.5%) wear their audio processors (AP) most of the time. Four (44.5%) with no perceivable benefit have become nonusers. Three of the five consistent ABI users reported good benefit. The other two ABI users who do wear their APs do not respond to sound in daily living but reported benefits such as "feeling sound" in a good way. CONCLUSIONS: In this study, five of nine patients (55.5%) with bilateral ossified cochlea had some degree of benefit from their ABI. An ABI may be useful in hearing restoration in postlingual patients with bilateral ossified cochlea due to meningitis. However, poor results may be related to side effects, which may necessitate deactivation of electrodes, long duration of auditory deprivation, or impairments in the auditory neural structures as a result of meningitis.

ABSTRACT: OBJECTIVE: To evaluate the results of delayed cochlear impantion performed in childhood and puberty in the light of speech language pathology assessments. METHODS: Totally 49 children with prelingual profound hearing loss were included in the study. All children received a cochlear implant between the ages of 5 and 19 years (Group 1 aged between 5 and 9 years, group 2 aged between 10 and 14 years, group 3 aged between and 15 and 19 years). The MAIS, MUSS and PLS-4 scores of children were evaluated one month before, and one year and two years after the operation. The descriptive statistics included several independent variables; age of implantation; gender; trade name of the implant; preoperative duration of hearing aid use; preoperative special education, family support and additional handicap. These variables were categorical variables. We used repeated measures analysis of variance to test improvements in MAIS, MUSS and PLS scores, and whether this improvement depend on the independent variables. In addition, we also tested the interaction between time and the independent variables. RESULTS: The preoperative MAIS, MUSS and language scores were significantly higher in older children compared to younger children (p<0.01). After two years these scores were similar between the all age groups (p>0.4). There was a significant age and time interaction (p=0.005). That is, improvement continued in all age groups in a parallel way and group 2 reached to the level of group 1 after two years. However, group 3 almost reached to a plateau level after two years. The family support was associated with the MAIS, MUSS and language scores of the patients (p=0.01), and there was a family support-time interaction (p<0.0001). In group 1 and 2, the way of communication shifted from total communication (lip reading, sign language, auditory) to auditory-verbal communication in a significant number of the patients (p<0.01). However, that change in the way of communication was not statistically significant in group 3 (p>0.05). CONCLUSION: The decision of delayed cochlear implantation in children can be made in the light of following parameters. A good family support is most important. The patients must be wearing hearing aids regularly since early childhood, and preferably use the auditory verbal communication. Evaluation of the patient with MAIS, MUSS and PLS is important to understand the level of receptive and expressive communication level.

ABSTRACT: Ethnic-specific differences in minor allele frequency impact variant categorization for genetic screening of nonsyndromic hearing loss (NSHL) and other genetic disorders. We sought to evaluate all previously reported pathogenic NSHL variants in the context of a large number of controls from ethnically distinct populations sequenced with orthogonal massively parallel sequencing methods. We used HGMD, ClinVar, and dbSNP to generate a comprehensive list of reported pathogenic NSHL variants and re-evaluated these variants in the context of 8,595 individuals from 12 populations and 6 ethnically distinct major human evolutionary phylogenetic groups from three sources (Exome Variant Server, 1000 Genomes project, and a control set of individuals created for this study, the OtoDB). Of the 2,197 reported pathogenic deafness variants, 325 (14.8%) were present in at least one of the 8,595 controls, indicating a minor allele frequency (MAF) > 0.00006. MAFs ranged as high as 0.72, a level incompatible with pathogenicity for a fully penetrant disease like NSHL. Based on these data, we established MAF thresholds of 0.005 for autosomal-recessive variants (excluding specific variants in GJB2) and 0.0005 for autosomal-dominant variants. Using these thresholds, we recategorized 93 (4.2%) of reported pathogenic variants as benign. Our data show that evaluation of reported pathogenic deafness variants using variant MAFs from multiple distinct ethnicities and sequenced by orthogonal methods provides a powerful filter for determining pathogenicity. The proposed MAF thresholds will facilitate clinical interpretation of variants identified in genetic testing for NSHL. All data are publicly available to facilitate interpretation of genetic variants causing deafness.

9 Article Transmastoid labyrinthectomy for disabling vertigo after cochlear implantation. 2014

Tutar, H / Tutar, V B / Gunduz, B / Bayazit, Y A. ·Otorhinolaryngology Head and Neck Surgery Department,Faculty of Medicine,Gazi University,Ankara,Turkey. · Audiology Department,Faculty of Medicine,Gazi University,Ankara,Turkey. ·J Laryngol Otol · Pubmed #25204744.

ABSTRACT: OBJECTIVE: To document the use of transmastoid labyrinthectomy in the treatment of disabling vertigo after unilateral cochlear implantation. METHODS: A 58-year-old man with severe-to-profound bilateral sensorineural hearing loss secondary to chronic otitis media underwent cochlear implantation in his right ear with a Pulsar Med-El device. The surgery was uneventful and the electrode was positioned correctly. He had episodic vertigo three months after implant surgery, and medical treatment and aggressive vestibular rehabilitation did not relieve the vertigo attacks. RESULTS: Right transmastoid labyrinthectomy was performed one year after cochlear implantation. The patient's symptoms were immediately relieved, and cochlear implant function was not adversely affected at follow up after three years. CONCLUSION: Transmastoid labyrinthectomy seems to be an effective, safe method for ablating the vestibular end organ after unilateral cochlear implantation.

10 Article Methods and preliminary outcomes of pediatric auditory brainstem implantation. 2014

Bayazit, Yildirim A / Kosaner, Julie / Cinar, Betul Cicek / Atac, Ahmet / Tutar, Hakan / Gunduz, Bulent / Altinyay, Senay / Gokdogan, Cagil / Ant, Ayca / Ozdek, Ali / Goksu, Nebil. · ·Ann Otol Rhinol Laryngol · Pubmed #24634154.

ABSTRACT: OBJECTIVE: The objective was to provide information about methods used and preliminary outcomes for pediatric ABI (auditory brainstem implant). STUDY DESIGN: An analysis of outcome was performed in children who received an ABI. METHODS: Twelve children received a MED-EL ABI system. Progress in audition and language was monitored through parental reports, questionnaires, profiles, and closed-set tests. RESULTS: The median number of active electrodes was 9 of 12. Seven of 12 users consistently respond to sound, and 5 of 12 do not. Highest performers can recognize words in small sets and have begun to use some words. CONCLUSION: Auditory brainstem implants appear to be beneficial for some pediatric patients who cannot benefit from traditional cochlear implant surgery. Benefits in the short-term can be recognition of environmental sounds, recognition of some words and very commonly used phrases, and the beginning use of words. Although some of our ABI users demonstrate no response to sound, they do want to wear their sound processors all waking hours. The cause of lack of response may be related to the second intervention, which might have led to displacement of the electrode array, or presence of additional handicaps or syndromes. However, the results are less than optimal. The relatively short postoperative follow-up duration is a considered weakness of this study.

11 Article Vibrant SoundBridge application to middle ear windows versus conventional hearing aids: a comparative study based on international outcome inventory for hearing aids. 2014

Atas, Ahmet / Tutar, Hakan / Gunduz, Bulent / Bayazıt, Yıldırım A. ·Audiology Unit, Cerrahpasa Faculty of Medicine, İstanbul University, İstanbul, Turkey. ·Eur Arch Otorhinolaryngol · Pubmed #23400404.

ABSTRACT: In this study, we aimed to compare the outcomes of satisfaction of the patients who used hearing aids preceding the vibrant sound bridge (VSB) application on middle ear windows (14 oval window and 5 round window). Nineteen adult patients with conductive or mixed hearing loss were included in the study. All patients used behind the ear hearing aids on the site which was selected for VSB application. The patients used hearing aids for at least 3 months before the VSB operation. The floating mass transducer (FMT) was placed on one of the middle ear windows (oval or round) in VSB operation. The patients were evaluated with International Outcome Inventory for Hearing Aids (IOI-HA) preoperatively after at least 3 months trial of conventional hearing aid and postoperatively after 3 months use of VSB. No perioperative problem was encountered. The total score of IOI-HA was significantly higher with VSB compared with conventional hearing aids (p < 0.05). No statistically significant difference was found between the daily use, residual activity limitations, satisfaction, impact on others, quality of life between middle ear implant and hearing aid (p > 0.05). The IOI-HA scores were significantly higher with the middle ear implant than the conventional hearing aid regarding benefit and residual participation restrictions (p < 0.05). Although the scores for quality of life assessment was similar between VSB and hearing aid use, there was a superiority of VSB in terms of benefit and residual participation restrictions as well as overall IOI-HA scores as the FMT was placed on one of the middle ear windows.

12 Article The evaluation of hearing loss in children with celiac disease. 2013

Bükülmez, Ayşegül / Dalgiç, Buket / Gündüz, Bülent / Sari, Sinan / Bayazit, Yildirim Ahmet / Kemaloğlu, Yusuf Kemal. ·Afyon Kocatepe University, Faculty of Medicine, Department of Pediatrics, Afyonkarahisar, Turkey. aysegulbukulmez@yahoo.com ·Int J Pediatr Otorhinolaryngol · Pubmed #23137854.

ABSTRACT: BACKGROUND AND AIMS: Celiac disease (CD) is an autoimmune enteropathy. The disease may be presented with extraintestinal manifestations including neurological findings. Epilepsy and ataxia are well known neurological disorders in CD. But there are very limited numbers of reports on sensory-neural hearing loss in CD in the literature. The aim of this study was to investigate the hearing functions in children with newly diagnosed CD. MATERIALS AND METHODS: Ninety-seven (194 ears) [56 girls, 41 boys (age range: 1.5-17 years)] newly diagnosed celiac disease patients and 85 sex and age-matched controls (170 ears) were included in this study. Hearing function was assessed by pure-tone audiometry, speech audiometry, tympanometry and otoacoustic emissions measurements. RESULTS: No significant difference were found between the patients and control groups measurements including the pure-tone audiometry, speech audiometry, tympanometry and otoacoustic emissions No significant difference was found for pure-tone audiometry, speech audiometry, tympanometry and otoacoustic emissions measurements in celiac patients according to the Marsh-Oberhuber classification (P>0.05). CONCLUSIONS: Our results showed that hearing functions of children with newly diagnosed CD were similar to healthy controls.

13 Article Labyrinthotomy or vestibulotomy in anatomic and congenital variations of the oval window and facial nerve. 2012

Al-Mazrou, Khalid A / Bayazit, Yildirim A. ·Department of Otolaryngology, King Saud University and King Saud Bin Abdulaziz University for Health Sciences, Riyadh, Saudi Arabia. ·ORL J Otorhinolaryngol Relat Spec · Pubmed #23295314.

ABSTRACT: OBJECTIVE: To present the results of our experience with labyrinthotomy or vestibulotomy in cases where the oval window is blocked by the facial nerve and in the presence of bilateral congenital agenesis of the oval window, respectively. STUDY DESIGN: Retrospective analysis of the records of the patients operated in two different centers. METHODS: Between 2007 and 2012, 5 ears of 4 patients who were operated on in two different clinics with a presumptive diagnosis of otosclerosis were included in the study. There were 3 female patients and 1 male. The ages ranged from 10 to 26 (mean 19 years). All patients had unilateral conductive hearing loss except 1 (10-year-old girl or patient 1). Pure tone averages were calculated at the frequencies 0.5, 1, 2 and 4 kHz both pre- and postoperatively according to the Committee on Hearing and Equilibrium 1995 Guidelines for the Evaluation of Results of Treatment of Conductive Hearing Loss. All patients underwent a middle ear exploration and postoperatively the initial audiological examination was performed after 6 months. RESULTS: Retrospective analysis revealed that vestibulotomy or labyrinthotomy was performed in 5 ears of 4 patients. Postoperative dizziness was encountered in 2 patients who had vestibulotomy due to oval window agenesis, which ceased spontaneously at 1 month postoperatively. The perioperative period was otherwise uneventful. None of the patients had sensorineural hearing loss or deterioration of hearing. There was a significant improvement in hearing after the operation. A 28-dB improvement in the mean air conduction pure tone thresholds was achieved. CONCLUSION: Vestibulotomy and labyrinthotomy are safe and effective procedures in terms of hearing restoration, which can be applied in cases of congenital agenesis of the oval window or obstruction of the oval window by the facial nerve.

14 Article Functional outcomes of Vibrant Soundbridge applied on the middle ear windows in comparison with conventional hearing aids. 2012

Gunduz, Bulent / Atas, Ahmet / Bayazıt, Yıldırım A / Goksu, Nebil / Gokdogan, Cagıl / Tutar, Hakan. ·Audiology Unit, Faculty of Medicine, Gazi University, Ankara, Turkey. bulentgunduz4@gmail.com ·Acta Otolaryngol · Pubmed #23039370.

ABSTRACT: CONCLUSION: Vibrant Soundbridge (VSB) application to the middle ear windows yields better functional outcomes than conventional hearing aids. However, speech discrimination scores obtained with VSB and conventional hearing aids are similar. OBJECTIVE: To assess audiological outcomes of round and oval window applications of VSB in comparison with conventional hearing aids. METHODS: Nineteen adult patients were included in the study. The patients had mild to moderate, moderate or moderate to profound conductive or mixed hearing loss. During surgery the floating mass transducer (FMT) was placed on the round (n = 14) or oval (n = 5) window. After the surgery, audiometric evaluation and free field audiometric evaluation of both ears was carried out. RESULTS: The hearing thresholds in the low frequencies were not significantly different between the conventional hearing aids and VSB. The functional gains obtained with oval and round window approaches were similar except for 500 Hz. The hearing thresholds in the mid and high frequencies were significantly better with VSB than the conventional hearing aids. The functional gain in the low frequencies was not significantly different between VSB and conventional hearing aids. The functional gain in the other frequencies was significantly better with VSB than conventional hearing aids.

Karamert, Recep / Bayazit, Yildirim A / Altinyay, Senay / Yılmaz, Akın / Menevse, Adnan / Gokdogan, Ozan / Gokdogan, Cagil / Ant, Ayca. ·Department of Otolaryngology, Gazi University Faculty of Medicine,06510 Besevler, Cankaya, Ankara, Turkey. dr.recepkaramert@yahoo.com ·Int J Pediatr Otorhinolaryngol · Pubmed #21996152.

ABSTRACT: OBJECTIVE: To analyze the association of GJB2 gene mutations with cochlear implant performance in children. METHODS: Sixty-five consecutive children who underwent cochlear implantation due to congenital profound senseurineural hearing between 2006 and 2008 were included in the study. In children, GJB2 gene mutation analysis was performed. Their auditory performance was assessed using MAIS, MUSS and LittlEARS tests. RESULTS: Twenty-two of sixty-five patients GJB2 mutations, and 35delG was the most frequent mutation. No significant difference was found between the auditory performance of mutation positive and negative children after one year follow up (p>0.05). CONCLUSION: GJB2 gene mutations do not impact on the outcome of cochlear implantation.

ABSTRACT: OBJECTIVE: We aimed to present the complications of auditory brain stem implantations (ABI) in pediatric patients which were performed via retrosigmoid approach. METHODS: Between March 2007 and February 2010, five prelingually deaf children underwent ABI (Medel device) operation via retrosigmoid approach. All children had severe cochlear malformations. The ages ranged from 20 months to 5 years. The perioperative complications encountered in 2 patients were evaluated retrospectively. RESULTS: No intraoperative complication was observed in the patients. Cerebrospinal fluid (CSF) leakage was the most common postoperative complication that was seen in 2 patients. The CSF leak triggered a cascade of comorbidities, and elongated the hospitalization. CONCLUSION: Pediatric ABI surgery can lead to morbidity. The CSF leak is the most common complication encountered in retrosigmoid approach. The other complications usually result from long-term hospital stay during treatment period of the CSF leak. Therefore, every attempt must be made to prevent occurrence of CSF leaks in pediatric ABI operations.
