    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.

    Two Case of Rhino-Orbito-Cerebral Mucormicosis Developed After COVID-19 Infection
    (2021) Demiroglu, Yusuf Ziya; Odemis, Ilker; Oruc, Ebru; Ozer, Fulya; Ulas, Burak; Canpolat, Emine Tuba; Yalcin, Cigdem; Sanli, Ozlem Oguc; 0000-0003-2638-0163; 0000-0001-5381-6861; 0000-0003-2638-0163; 0000-0002-6099-4786; 34666667; AAG-2486-2022; ABC-1809-2020; AFK-3690-2022
    Coronavirus 2019 (COVID-19) infection causes excessive cytokine response and a decrease in cellular immune response and this increases susceptibility to fungal co-infections. Mucormycosis is a rare, life-threatening invasive fungal infection. In this report, two cases who developed rhino-orbito-cerebral mucormycosis shortly after having COVID-19 infection were presented. The first case was a 68-year old woman who admitted to our clinic with orbital cellulitis in her left eye and had a known diagnosis of asthma and rheumatoid arthritis. She was diagnosed with COVID-19 pneumonia 40 days ago, stayed in the intensive care unit for a long time, and received pulse steroid (1000 mg methylprednisolone), interleukin-1 (IL-1) inhibitor (anakinra) and broad-spectrum antibiotic treatments together with antiviral therapy during this period. The second case was a 63-year-old male patient with known diabetes mellitus, hypertension and retinitis pigmentosa, with a history of hospitalization in the intensive care unit due to COVID-19 pneumonia 20 days ago and received pulse steroid therapy during this period. He admitted to our clinic with the complaints of droopy right eyelid, swelling, nausea and vomiting. In both cases, paranasal sinus tomography findings were consistent with invasive sinusitis. Functional endoscopic sinus surgery was performed immediately in less than 16 hours from the first admission in both cases. Histopathological examination of the both cases revealed results consistent with mucormycosis. Mucorales spp. was isolated in sinus tissue culture of the second case taken during the operation. Both of the patients received liposomal amphotericin B. First case died on the 19th day of the treatment. Second case was discharged with full recovery after nine weeks of treatment. The suppression of cellular immunity during the COVID-19 infection, and the use of steroids and interleukin inhibitors in the treatment of severe cases may increase secondary invasive fungal infections. Therefore, clinicians should more frequently consider possible fungal infections in patients with COVID-19.

    Evaluation of the possible effect of magnetic resonance imaging noise on peripheral hearing organ with the otoacoustic emission
    (2020) Turay, Cevahir Bulut; Ozer, Fulya; Yildirim, Tulin; 0000-0001-5381-6861; 0000-0002-8453-6069; 32629148; ABC-1809-2020; AAJ-2445-2021
    Purpose: The aim of this study is to evaluate the effect of noise produced by magnetic resonance imaging (MRI) device on hearing by using objective and subjective audiological assessments. Methods: A total of 38 patients between the ages of 18 and 50 without hearing loss, and had performed MRI for brain, head, neck or cervical imaging were included in this prospective clinical study. Pure tone audiometry, speech audiometry, high frequency audiometry, transient evoked otoacoustic emissions (TEOAE) and distortion product otoacoustic emission (DPOAE) were performed before and after MRI. Results: There was no statistically significant difference in TEOAE, pure tone audiogram, high frequency audiogram and speech audiogram thresholds. In DPOAE, the median value before and after MRI at the frequency of the left ear at 4.0 kHz was 13.6 (8.5-19.9) and 15.7 (8.9-20.7) SNR respectively (p > .05). The median value before MRI at the right ear 4.0 kHz frequency was 14.1 (9.1-20.5) SNR, whereas the median value after MRI was 13.2 (8.8-19.8 SNR (p = 0,03). There was no statistically significant difference in other frequencies in DPOAE. Conclusions: This is the first objective study that examines the MRI noise on speech audiometry and otoacoustic emission together. However, the effect of MRI noise on hearing pathway is still doubt. Based on the difference at 4 kHz frequency on DPOAE; on-earphones may not sufficiently protect the patients from the MRI noise and this issue should deserve further research.

    A Rare Diagnosis in the Neck During Childhood: Congenital Chondrolipoma
    (2017) Ozer, Fulya; Bal, Nebil; 0000-0001-5381-6861; 24715556; ABC-1809-2020
    Chondrolipomas are mesenchymal tumors that found as mature cartilage tissue in a fat tissue. A 2-year-old boy was seen with a complaint of a mass of the neck. On physical examination of the child, there was a one-centimeter mass above the sternocleidomastoid muscle on the lateral neck. Pathological examination of this mass after excision was reported as chondrolipoma. Chondrolipomas are seen mostly in the breast and in the adult. They are rare tumors of the head and neck area and seen mostly the in oral cavity here. This is the first case of chondrolipoma with this age and localization combination in the literature. Chondrolipoma should therefore also be considered in the differential diagnosis of congenital masses located at lateral cervical area.
