4 (SD = 2.6), and for the decrease in vigilance, it was 0.3 (SD = 0.5). When comparing the performance of adults and children, a statistically significant difference was observed for inattention ( p  = 0.000) and impulsivity ( p  = 0.001) error types, as well as in the total error score ( p  = 0.000) and in decreased vigilance ( p  = 0.0003). Conclusion  The performance of adults in the SAAAT differed from the children's parameters, since adults showed lower scores in all variables of the instrument.Introduction  Isolated nasal obstruction (INO) is a common complaint of multiple etiology. The preoperative evaluation of patients presenting with nasal obstruction and deviated nasal septum (DNS) does not typically include imaging. The benefits of performing computed tomography (CT) in the preoperative setting are inconclusive. Objective  Assessing the contribution of preoperative CT to the surgical treatment of non-sinusitis patients presenting with INO and DNS. Methods  A retrospective cohort study on patients referred to surgery for nasal obstruction due to DNS or turbinate hypertrophy between 2006 and 2015. Data was retrieved from patients' medical charts. The CT scans and clinical data were reassessed by a second surgeon blinded to the patients' clinical course. Results  Seventy of the 843 patients (8.06%) who underwent endoscopic sinonasal procedures during the study period had presented with INO and met the inclusion criteria. Thirty-eight (55.88%) of them underwent CT scans during their preoperative assessment. Modification of the initial preoperative planning based on the radiological findings was required in 32 cases (84.2%). When reassessed by a second blinded surgeon, 58% of cases required surgical modification rather than classical submucosal resection of nasal septum and turbinate reduction ( P  = 0.048). Conclusion  Computed tomography was found beneficial in the preoperative planning for patients with INO. The original surgical plan based upon physical examination findings was modified based on radiological findings in 84.2% of the patients.Introduction  The use of cochlear implants and hearing aids (bimodal) has been growing with the expansion of the indication for them, and it is important to ensure protocols so that there is a balance of the loudness regarding the two devices. Objective  To evaluate if the limited complex sounds present in the frequency bands of the current devices enable the balance of the loudness in adult users of bimodal stimulation, and to analyze if speech recognition improves after balancing. Methods  A prospective cross-sectional study with convenience sampling. The sample was composed of 25 adults who had used either a cochlear implant for at least 6 months or a contralateral hearing aid, with a mean age of 46 years. The balancing of the loudness was performed in an acoustic room with the computer's sound box (0° azimuth at 70 dB SPL). The instrumental sounds were filtered through eight different frequency bands. The patients used both hearing devices and were asked if the sound was perceived to be louder in one of the ears or centrally. The speech test was evaluated with sentence silence (65 dB SPL) and/or noise signal ratio of 0 dB/+ 10 dB in free field at 0° azimuth, before and after balancing. Results Out of the 25 patients, 5 failed to achieve balance at every tested frequency, and 3 achieved balance at almost every frequency, except 8 kHz. There was a significant difference between the speech recognition test only in silence before and after balancing. Conclusion Most patients achieved sound equalization at all evaluated frequencies under the complex-sound protocol. Additionally, most patients experienced improved speech recognition after balancing.Introduction  There are no definitive parameters to guide the etiology and severity of pediatric antrochoanal polyps. Objective  The aim of our study is to compare the values of blood cell distribution parameters in cases of pediatric antrochoanal polyps (ACPs) with those of the control group. These values may be guiding parameters in determining the etiology of ACPs and evaluating the severity of the disease and the risk of recurrence. Methods  Blood count values of patients operated for pediatric ACPs were retrospectively analyzed and compared with the data of the control group with the same age and gender distribution. The ACPs group was divided into subgroups in terms of inflammation, severity, and recurrence, and these subgroups were statistically compared as well. Results  When the ACP patient group and the control group were compared, there was no statistically significant difference between the two groups. When we compared the patients considering the CT findings, there was a statistically significant difference between the stage III patients and the control group in terms of mean platelet volume (MPV) and platelet-to-lymphocyte ratio (PLR) values ( p   less then  0.05 in both). Similarly, the MPV and PLR values were significantly higher in the recurrence patient group than in the control group. ( p   less then  0.05 in both). click here Conclusion  As a result of the data obtained, it can be suggested that inflammatory parameters in pediatric cases of ACPs vary in terms of recurrence and the severity of the disease.Introduction  Chronic otitis media (COM) with a central perforation or a concomitant cholesteatoma are both inflammatory lesions, however, with different etiologies. Both entities may present with an intact chain, and the final reconstruction is quite similar. Does it also apply for the hearing outcome? Objectives  In a retrospective analysis, we investigated the preoperative hearing and the final hearing outcome of two groups of patients those with COM and those with cholesteatoma, and compared various factors. Methods  Patients operated between 2010 and 2019 were entered prospectively into a research database, and the integrity of the ossicular chain, the extent of the cholesteatoma, and the findings on computed tomography (CT) scans were retrospectively analyzed and correlated to the final hearing outcome. Results  Out of 210 tympanoplasties for COM, 162 (80%) presented with an intact chain, and 85 (40%) ears could be analyzed. Out of 283 cholesteatoma surgeries, 53 (19%) ears presented with an intact chain.
