Objective: Cochlear implantation (CI) is an electronic device that converts mechanical sound energy into electrical signals and transmits it directly to the cochlea, allowing sound perception. These implants were applied to patients with severe sensorineural hearing loss who did not or had little benefit from the conventional hearing devices. This study aimed to investigate behavioral problems, find related factors, and determine the relationship between behavioral problems and parents' attitudes in children with CI. Methods: The investigation involved the participation of fifty individuals, comprising 26 males and 24 females, between 4 and 18 years, with a mean age average of 4 +/- 1.56 without any neurological and developmental problems. Inclusion criteria required a minimum of one year post-CI follow-up and a corresponding minimum duration of one year utilizing CI. Achenbach's Child Behavior Checklist (CBCL) assessed behavioral aspects. Categories of Auditory Performance II (CAP) and The Speech Intelligibility Rating Scale (SIR) scales were employed to evaluate auditory performance and speech intelligibility. Parental attitudes were gauged using the Parent Attitude Research Instrument (PARI). The selection of fifty patients was accomplished through a simple random sampling technique, with no considerations for gender or social status differences during case selection. Results: The patients who applied the CI bilaterally were more successful than the one-sided. The success rate of patients who had comorbidities was statistically significant. Aggressive behavior was less in patients operated on before age 4. There are no differences between the relations of friend circle, art, and sports-interested patients. For CAP II and SIR, there is a moderate statistical significance between the duration of use and CAP. CAP scores were analyzed high in patients who used the device for over six years. There is a moderate statistical significance between CAP and SIR correlation. Our research found a statistically significant decrease in all behavioral scales when comparing preoperative and postoperative scores. Although there was only a non-significant decrease in the delinquent behaviors score, a decrease was still observed. There were significant changes in males but no significant difference based on gender in our study. Conclusion: The findings imply that implementing cochlear implants in younger children might yield even greater advantages. Our research adds to the expanding collection of evidence endorsing CI as a viable therapeutic choice for youngsters with hearing impairments, underscoring the necessity for continued investigations within this domain.

(2019) Tokat, Taskin; Catli, Tolgahan; Bozkurt, Ergun Basaran; Atsal, Gorkem; Muderris, Togay; Olgun, Levent; 31846909
OBJECTIVES: 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.

(2022) Atsal, Gorkem; Demir, Emine; Yildirim, Oben; Edizer, Deniz Tuna; Olgun, Levent; 34690315
We aimed to evaluate whether the nasal septum deviation affects the development of sinonasal structures. Patients who had undergone paranasal sinus computed tomography (PNS-CT) imaging due to nasal obstruction were divided into 3 groups according to the septal deviation angle; group I: 0 degrees to 9 degrees, group II: 10 degrees to 15 degrees, and group III: >15 degrees. The features of sinonasal structures were recorded when evaluating PNS-CT. There were totally 234 patients, 119 patients in group I, 68 in group II, and 47 in group III. On the opposite side of the deviation, keros 3 was significantly more in group III (P < 0.001). Although the incidence of concha bullosa and agger nasi cell were not affected by the degree of deviation (P > 0.05), the incidence of Haller and Onodi cells were significantly higher in group III (P < 0.001). In addition, all cells were observed more in the opposite side of the deviation in each group (P < 0.001). Maxillary sinus retention cysts and hypoplasia of maxillary and frontal sinuses, as an indicator of the low pneumatization of the sinuses, are seen more on the same side of nasal septum deviation, increasing with the degree of deviation increases (P < 0.001). Nasal septum deviation affects the development of sinonasal structures by affecting the pneumatization. Preoperative PNS-CT evaluation is important in order to be aware of the situations that we may encounter during surgery and to provide adequate treatment.
Sinonasal inverted papilloma: Recurrence, surgical management, and mini review
(2021) Olgun, Levent
Objective: Sinonasal inverted papilloma (SIP) has a high rate of recurrence and a potential to be transformed into a malignant disease, hence surgery is the treatment of choice. In this study, we aimed to identify the preoperative features of patients diagnosed with SIP and discuss treatment options, recurrence rates, and postoperative clinical outcomes. Methods: Twenty-six patients who were diagnosed with SIP between 2010 and 2014 in a training and research hospital were included in the study. Their charts were reviewed retrospectively. The complaints at admission, findings of anterior rhinoscopy, nasal endoscopy, and radiological examinations were recorded along with histopathological features. Different surgical treatment modalities and recurrence rates were analyzed regarding tumor characteristics and postoperative outcome. Results: The average postoperative follow-up was 32.1 +/- 20 months. According to Krouse classification, 15 (57.7%) patients were staged as T3, eight (30.8%) were T2, and three (11.5%) were T1. Endoscopic sinus surgery was performed in 21 patients. Medial maxillectomy via lateral rhinotomy (classical technique) was performed in five patients. Two patients (7.7%) who had endoscopic surgery had a recurrence of SIP; however, the rate was not statistically significant when compared with that of patients who underwent the classical technique. Histopathological examination revealed chronic rhinosinusitis with nasal polyposis (19.2%), squamous metaplasia (3.8%), and squamous cell carcinoma (7.7%) concurrent with SIP. Conclusion: Endoscopic surgery should be the first choice for the treatment of SIP. It may be combined with classical methods in some patients with advanced stage disease, especially when the tumor spreads to areas that are difficult to reach. Following surgical intervention, the patients should be followed carefully to identify recurrence or malignant transformation as early as possible.

(2020) Catli, Tolgahan; Tokat, Taskin; Bozkurt, Ergul Basaran; Adibelli, Zehra Hilal; Ergun, Ugurtan; Altas, Enver; Olgun, Levent; 32283908
Background/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.

(2022) Tokat, Taskin; Catli, Tolgahan; Bozkurt, Ergul Basaran; Olgun, Levent; 35193846
BACKGROUND: 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.
