(DERMAN MEDICAL PUBL, 2018-01-01) Mutlu, Ahmet; Iseri, Mete; Durgut, Merve; Topdag, Murat; Erdogan, Selvet; Ozturk, Murat
Aim: Cochlear implantation (CI) is a commonly performed procedure for severe to profound deafness in patients. It has been widely used for this purpose, and it becomes more complicated than expected for new institutes. In this report, we aimed to discuss the patient features, surgery indications, results of the CI surgeries in the experience of a single center. Material and Method: We retrospectively analyzed 65 patients who were underwent CI in a tertiary hospital. Hearing loss etiologies, hearing results and postoperative complications were assessed. Results: Sixty-five patients were evaluated within in two groups as 0-6 years-old and over 7 years-old. Twenty-nine patients were placed in 0-6 years-old group, and 36 patients were placed in over 7-years-old group. In 0-6-years-old group
Expansion to the Motion Sickness Susceptibility Questionnaire-Short Form: A Cross-Sectional Study
(KOREAN AUDIOLOGICAL SOC, 2022-01-01) Ugur, Emel; Konukseven, Bahriye Ozlem; Topdag, Murat; Cakmakci, Mustafa Engin; Topdag, Deniz Ozlem
Background and Objectives: The primary objective of this study is to investigate the necessity of questioning virtual reality systems in the motion sickness susceptibility questionnaire (MSSQ)-short form. The secondary objective of this study is to determine the validity and reliability of the Turkish version of the MSSQ-short form, with proven validity and reliability. Subjects and Methods: In the questionnaire form, for which expert opinion was obtained to maintain linguistic equivalence, the virtual reality items were added to the questionnaire. The questionnaire was then administered to 297 individuals. The results were statistically analyzed with and without these virtual reality items for validity and reliability. Results: After the addition of the virtual reality items, the reliability of the questionnaire was found to be quite high (Cronbach's alpha r=0.912). The norm values between the original MSSQ-short form (12.9 +/- 9.9) and the Turkish MSSQ-short form (13.8 +/- 12.9) were found to be consistent. Conclusions: Motion sickness symptoms can occur not only during movement, but also with indirect stimulus. Our findings suggest that adding virtual reality items to the original form is important in long term practical applications. Our results show that the Turkish version of the original questionnaire is quite reliable. Submission of the MSSQ-short form in Turkish will be useful for documentation and will also encourage further research in this area.
The Healing Effects of Autologous Mucosal Grafts in Experimentally Injured Rabbit Maxillary Sinuses
(KOREAN SOC OTORHINOLARYNGOL, 2016-01-01) Topdag, Murat; Kara, Ahmet; Konuk, Esma; Demir, Necdet; Ozturk, Murat; Caliskan, Sebla; Topdag, Deniz Ozlem; Ulubil, Arif; Keskin, Ibrahim Gurkan; Iseri, Mete
Objectives. Healing processes of the nose and paranasal sinuses are quite complex, and poorly understood. In this study, we aimed to compare the effect of mucosal autologous grafts on the degenerated rabbit maxillary sinus mucosa with spontaneous wound healing. It is hypothesized that mucosal grafts will enhance ciliogenesis and improve the morphology of regenerated cilia. Methods. Ten female New Zealand rabbits were included in the study. They underwent external maxillary sinus surgery through a transcutaneous approach. A total of 20 maxillary sinuses were randomly divided into 2 groups: `spontaneous healing group' and `autologous graft group.' The animals were sacrificed at the 14th day after the surgery. Scanning electron microscope (SEM), and light microscope were used for the evaluation. Results. Cellular composition of the graft group is better than the spontaneous healing group. The graft group had larger areas covered with ciliary epithelium than the spontaneous healing group, and the mean length of the cilias were also longer. Additionally, there were wider cilia with abnormal morphology areas in the spontaneous healing group. Conclusion. In our opinion, covering of the denuded areas with a graft improves re-epithelization, and may prevent the early complications after sinus surgeries.
