Item Effects of Surfactant on Biofilm Formation on Silicone Nasal Splints(2015) San, Turhan; Ertugay, Omer Cagatay; Catli, Tolgahan; Acar, Mustafa; Ertugay, Cigdem Kalaycik; Dag, Ilknur; Cingi, Cemal; 24874588Biofilms are sessile communities of bacteria embedded in self-produced extracellular polysaccharide matrix and are considered to be responsible for bacterial infections in humans. Topical surfactant use on silicone nasal splints may have a preventive effect on biofilm formation. The objective of this study is to investigate the effect of surfactant-containing nasal solutions on biofilm formation over the surface of silicone nasal splints. Forty patients were randomized after septoplasty to receive surfactant-containing saline solution (group 1) or saline without surfactant (group 2). At the postoperative 48th, 72th and 96th hours, pieces of splint samples were taken and prepared for scanning electron microscopic evaluation. Biofilm formation was observed in 3, 6 and 14 of 20 samples in group 1 (surfactant used) and 3, 14 and 20 of 20 samples in group 2 (control) at 48th, 72th and 96th hours, respectively. Biofilm formation incidences of groups at 48th hour were similar (p > 0.05), whereas it was significantly lower at group 1 regarding 72th and 96th hours (p < 0.05). Surfactant-containing nasal solutions have an inhibitory effect on biofilm formation over the surface of silicone nasal splints especially after 48 h. Surfactant-containing nasal solutions may have an important role in nasal septal dressing in the future.Item Parents' View on Quality of Life after Cochlear Implantation in Children with Auditory Neuropathy(2019) Tokat, Taskin; Catli, Tolgahan; Bozkurt, Ergun Basaran; Atsal, Gorkem; Muderris, Togay; Olgun, Levent; 31846909OBJECTIVES: The aim of this study is to evaluate the quality of life in pediatric patients with auditory neuropathy according to the perspective of their parents after cochlear implantation. MATERIALS and METHODS: The pediatric patients, who underwent cochlear implantation with the diagnosis of auditory neuropathy at Izmir Bozyaka Training and Research Hospital ENT Clinic between January 1997 and May 2017, were included to the study. "Parents' Perspective tonnaire" developed by Nottingham Pediatric Cochlear Implant Programme was used in the study. The questionnaire was composed of 11 subscales and 58 questions in total. RESULTS: The study included 26 pediatric patients (14 female, 12 male) who used cochlear implant for at least 1 year. The mean age of patients was 10.91 +/- 3.85(4.3-17.3 years old) and implantation age varied between 14 months and 80 months. (median; 35.65 +/- 20.03 months). Patients who attended school had more self-confidence, and also those having implant use over 6 years had a better self confidence and social relationship. CONCLUSION: Cochlear implantation not only improves the ability of hearing but also provides development of speech and language skills and therefore enhancing the patient's quality of life. From the perspective of parents, the use of cochlear implant in the children with auditory neuropathy improves the quality of life in many different ways. The perspective of parents can provide a multidimensional evaluation about the child's progress, therefore, it should be taken into consideration by the staff in implant centers.Item Surgical considerations and audiological results of cochlear implantation in patient with otosclerosis(2020) Catli, Tolgahan; Tokat, Taskin; Bozkurt, Ergul Basaran; Adibelli, Zehra Hilal; Ergun, Ugurtan; Altas, Enver; Olgun, Levent; 32283908Background/aim: To emphasize the role of cochlear implantation (CI) in the auditory rehabilitation of patients with otosclerosis (OS) and share our surgical experiences on this rare group of patients. Materials and methods: Retrospective analysis of the patients who have a diagnosis of otosclerosis and implanted between January 1998-May 2019 was performed. Preoperative and postoperative clinical, radiological, audiological and surgical findings are presented. Results: Among 2195 patients who have been implanted in our institution, 12 (0.54%) met the diagnostic criteria of OS according to their preoperative (clinical, radiological, audiological) and peroperative (surgical) findings. Electrode insertion was performed via "round window membrane and cochleostomy" in 8 and 4 patients, respectively. No major complications occured. All patients showed satisfactory performances by means of audiometric scores postoperatively. Nonauditory stimulation (NAS) which manifested as "facial twitching" was a challenging problem in one patient during the surgery and subsided after the operation. Conclusion: Our experience on CI in patients with OS revealed that the implantation was a relatively safe procedure and had satisfactory impact on audiological performances.Item Surgical Methods and Auditory Outcomes of Cochlear Implantation in Cochlear Ossification(2022) Tokat, Taskin; Catli, Tolgahan; Bozkurt, Ergul Basaran; Olgun, Levent; 35193846BACKGROUND: The aim of this study was to evaluate the surgical and auditory outcomes of cochlear implantation in patients with cochlear ossification. METHODS: This study comprised 54 patients with cochlear ossification who underwent cochlear implantation in the cochlear implant center of a tertiary care hospital between January 1998 and May 2019. Clinical data were evaluated including surgical findings and audiological performances. The auditory outcomes of the implanted patients were assessed through the Categories of Auditory Performance-II test and Speech Intelligibility Rating test, respectively. The outcomes of patients with cochlear ossification were compared with those of 54 patients selected for the control group who underwent implantation with no cochlear ossification. RESULTS: Auditory outcomes were comparable between the study group and the control group. The control group obtained significantly higher scores than those of the study group when compared using the Categories of Auditory Performance-II test and Speech Intelligibility Rating test batteries. Patients with meningitis produced poorer outcomes within the group comparisons of the study group. None of the patients experienced surgical complications. The extent of ossification was analyzed in terms of its effectiveness on audiological performance. Patients with complete ossification had significantly lower Categories of Auditory Performance-II and Speech Intelligibility Rating test scores. CONCLUSION: Cochlear implantation is a safe and beneficial procedure, even in patients with cochlear ossification. The ossified cochlea may require varied drill techniques beyond traditional implantation surgery for the insertion of the electrode array. It is, however, still difficult to predict audiological outcomes in patients with cochlear ossification.
