(2016) Bayazit, Yildirim; Kosaner, Julie; Celenk, Fatih; Somdas, Mehmet; Yilmaz, Ismail; Altin, Gokhan; Cevizci, Rasit; Yavuz, Haluk; Ozluoglu, Levent; https://orcid.org/0000-0003-3320-204X; https://orcid.org/0000-0002-2150-0237; 26485185; F-6315-2015; AAI-8020-2021
Objectives/HypothesisThe aim of this study was to evaluate outcomes of postlingual postmeningitic patients who received an auditory brainstem implant (ABI). Study DesignRetrospective analysis was performed on postlingual postmeningitic patients with bilateral profound sensorineural hearing loss who underwent ABI between the years 2007 and 2014 MethodsAll 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. ResultsNine 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. ConclusionsIn 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.

Cochlear Implant Failure in the Pediatric Population
(2021) Ozer, Fulya; Yavuz, Haluk; Yilmaz, Ismail; Ozluoglu, Levent N.; 0000-0003-3320-204X; 34551468; F-6315-2015
Background and Objectives: In cochlear implant (CI) surgery, the results and causes of revision and reimplantation may guide surgeons in establishing surgical protocols for revision surgery with safe audiological outcomes. The aim of this study was to review our experience in terms of etiology, surgical strategy, and hearing outcomes in pediatric patients who underwent CI removal and reimplantation. Subjects and Methods: All patients received implants of the same brand. Pre and postoperative Categories of Auditory Performance score and aided free-field pure tone audiometry thresholds were noted. In vivo integrity tests were performed for each patient and the results of ex vivo tests of each implant were obtained from manufacturer. Results: A total of 149 CIs were placed in 121 patients aged <18 years. The revision rate in children was 6.7% (10/121 children). Six patients had a history of head injury leading to a hard failure. The causes of reimplantation in others were soft failure (n=1), electrode migration (n=1), infection (n=1), and other (n=1). All patients showed better or similar postreimplantation audiological performance compared with pre-reimplantation results. Conclusions: It is very important to provide a safe school and home environment and educate the family for reducing reimplantation due to trauma. Especially for active children, psychiatric consultation should be continued postoperatively.

This paper examines the reports on the selection criteria and the post-operative performance of 25 children implanted with the Neurelec Digisonic SP. This study reported benefits from Neurelec Digisonic SP cochlear implant in auditory and speech perception outcomes. There has been a lack of studies into the additional factors such as level of the mothers' education and bilingualism, which is a factor that may have a significant effect on the success of cochlear implantation. This paper examines the reports on the reasons for the differences in performance and the post-operative performance of 25 children implanted with the Neurelec Digisonic SP. Meaningful Auditory Integration Scale and Meaningful Use of Speech Scale questionnaires were used just before 3, 6, 12, and 18 months following implantation. Electrode array was inserted without difficulty in all cases, with no complications to date. This is a retrospective and cross-sectional study and all the data were collected between March 2010 and December 2012. Auditory performance improved over time for up to 12 months after implantation. Our experience indicates that the Neurelec Digisonic SP cochlear implant system in children under the age of two is relatively safe and reliable. The Neurelec Digisonic SP device surgery can be performed without complications. Auditory performance results support the effectiveness of early implantation. These important findings further support the importance of professionals working very closely with parents or especially mothers and enhancing their involvement in achieving therapy goals to develop auditory skills and speech in young children following cochlear implantation.
Tracheoesophageal Puncture Closure with Annular Mucosal Flap
(2021) Yavuz, Haluk; Vural, Omer; 0000-0003-3320-204X; 0000-0001-7157-0850; 33544436; F-6315-2015; AAJ-1454-2021
Background To present an effective and easily applicable method for tracheoesophageal puncture (TEP) closure by using a localized annular flap instead of bulky and distant flaps. Methods The medical records of patients who underwent TEP closure surgery with the annular mucosal flap technique between July 2012 and August 2018 were retrospectively reviewed. Fistula size, indication for closure, duration of surgery, radiotherapy status, and surgery results were analyzed. Results We have used our technique in nine patients. No postoperative bleeding, wound infection, esophageal stenosis, and tracheostoma stenosis occurred. In all these patients except one, successful closure was achieved. None of the patients had a recurrence of the TEP. Conclusion The annular mucosal flap technique for TEP closure is easy and quick to apply. The patient's oral feeding at the sixth hour after procedure without using a nasogastric tube makes the technique preferable as a priority.
Transoral Approach to the Giant Deep Lobe Parotid Gland Pleomorphic Adenoma
(2021) Yavuz, Haluk; Vural, Omer; 0000-0003-3320-204X; 0000-0001-7157-0850; 33464770; F-6315-2015; AAJ-1454-2021
Parapharyngeal space tumors are rare tumors that make up about 0.5% to 1% of all head and neck neoplasms. The majority of parapharyngeal space tumors, which are usually benign, consist of salivary gland tumors and neurogenic tumors. Although the transcervical, transparotid or transmandibular approach is generally preferred for the excision of these tumors, the transoral approach, which is more advantageous in terms of cosmetics and function, can be applied in selected cases. This article presents a case in which the giant pleomorphic adenoma originating from the deep lobe of the parotid gland is removed by transoral approach.
