Objective: This study investigated the impact of different local corticosteroid applications on impedance measurements in patients with cochlear implants. Methods: The study was designed as a controlled, randomized, and prospective study in which 34 consecutive patients who had undergone cochlear implant surgery were divided into three groups. The first group received intracochlear dexamethasone, in the second group the middle ear cavity was filled with dexamethasone, and the third group did not receive dexamethasone. Intraoperative, postoperative 1st week, 1st month, 3rd month, 6th-month neural response telemetry, and impedances were measured. The measurements were compared by electrode groups representing the different regions of cochlea like basal (1–7), middle (8–13), and apical (14–22) regions. Results: The intergroup analysis showed no statistically significant differences in impedance measurements of the basal, middle, and apical regions (p>0.05). However, the impedances were lower in the two dexamethasone groups, especially in the basal and middle parts. Sixth month impedances were also lower in the dexamethasone groups. There was apparent stability in the impedance of the basal region with the intracochlear application during the first week. Conclusion: Local dexamethasone applications had a potentially positive impact on the impedance of the basal and middle regions. Patients had lower impedances than the control group during follow-up and at the endpoint. The increase in the apical region may indicate that dexamethasone was not reaching the apical zone in local applications.

Objective: We aimed to adapt the Facial Nerve Grading System 2.0 (FNGS 2.0) to Turkish and to investigate the validity and the reliability of the Turkish version.Methods: The original FNGS 2.0 was translated into Turkish and validated by international standards. Six Turkish physicians, three specialists and three residents, independently rated the videos, two times each, of 40 adult facial palsy patients. Inter-rater and intra-rater reliability were assessed using the intraclass correlation coefficient (ICC) and Cronbach’s alpha coefficient. As another indication of reliability, “generalizability” was also evaluated. For all analyses, a p value of

Objective: To adapt an objective surgical assessment tool (OSATS) for adenotonsillectomy/tonsillectomy to Turkish.Methods: A prospective longitudinal validation study was planned. Adenoidectomy items were added to the tonsillectomy OSATS. Data were collected from 80 real-time observed surgical performances. To examine interrater reliability, 25 performances were simultaneously scored by two evaluators. In total, 105 test forms were filled, and reliability and validity studies were conducted.Results: Regarding reliability, Cronbach's alpha values were found to be >0.95, indicating very high internal consistency. For interrater reliability, a statistically significant positive correlation was found between the two evaluators’ task-specific checklist (TSC) (p=0.0001; r=0.969) and global rating checklist (GRC) (p=0.0001; r=0.957). Between the TSC and GRC, there was a statistically significant positive correlation (p=0.0001; r=0.951). A model was developed using the generalizability theory, and the highest variances belonged to surgical processes. Regarding validity, the trainers’ scores were significantly higher than the trainees’ scores (p=0.0001). As surgical experience increased, both the TSC and the GRC scores significantly increased (p=0.0001). A trainee’s first-ever 34 adenotonsillectomy performances were scored. A scatter plot of the obtained data showed that the trainee had gained more scores as the number of operations increased.Conclusion: The results indicate that adenotonsillectomy OSATS is a reliable and valid tool for the assessment of residents’ surgical skills. This is the first OSATS developed for adenotonsillectomy in the Turkish literature. It is ready to be used in the operating room to provide constructive feedback and monitor the development of trainees’ surgical skills in adenotonsillectomy.

Objective:To demonstrate the histopathological effects of the long-term use of cromolyn sodium on healthy rat nasal mucosa using the light microscope.Methods:The animals were grouped according to the intranasal administered agents: first group (n=10), intranasal 10 µL saline administration; second group (n=10), intranasal 10 µL cromolyn sodium with the help of a micropipette for one month duration.Results:When we assessed mucosal edema and increased goblet cell number, there were no statistical differences between control and study groups (p>0.05). However, the assessment of decreased epithelial thickness and squamous metaplasia between control and study groups revealed significant differences (respectively: p=0.001, p=0.001; p

Pilonidal sinus is a cronic disease of sacrococcygeal area that is created by mixing “pilus” which is meaning bristle and “nidus” which is meaning nest in Latin. Although it is most frequently seen at sacrococcygeal area; it’s also seen at axilla, inguinal area, umblicus, neck, scalp and betveen fingers. In this case 18 years old female patient that came to us with puffiness behind ear for the last 6-7 month is presented. In the preoperative survey there was a hyperemic, soft, mobile, painless mass at the right postauricular area. That mass is excised totally under general anesthesia. It’s reported pilonidal sinus after histopathologyc investigation. The patient did not have any trouble in postoperative period. Case is discussed by the side of location in the light of past literatures.
