While the metabolic syndrome (MetS) is a multifactorial disease that includes diabetes, hypertension, dyslipidemia, and obesity, which are known to be associated with SSNHL. Weather conditions have long been known to affect the SSNHL. This study aimed to make a clear connection between MetS, or weather conditions, and the severity and prognosis of SSNHL. 127 SSNHL patients have been divided into the MetS group and the non-MetS group, and the demographic and clinical characteristics of the 2 groups have been analyzed retrospectively. There were 52 (40.9%) patients in the MetS group, while there were 75 (59.1%) patients in the non-MetS group. The rate of vertigo, hypertension, diabetes, lower high-density lipoprotein cholesterol (HDL-C) levels, high triglyceride (TG), and body mass index (BMI) ≥25 (kg/m2 ) were significantly higher in the MetS group than those in non-MetS group. Vertigo, hypertension, and Mets were linked to the severity of hearing loss. The rate of complete recovery and partial recovery in the MetS group was clearly lower than that in non-MetS group. According to the multivariate analysis, MetS was significantly associated with a poorer prognosis of SSNHL; a high ambient temperature difference at onset and hypertension were correlated with a poor prognosis. These results demonstrate that the severity and prognosis of SSNHL can be influenced by the MetS. High ambient temperature differences at onset and hypertension were indicators of a poor prognosis for SSNHL.","PeriodicalId":94238,"journal":{"name":"The journal of international advanced otology","volume":"20 3","pages":"203-209"},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11232085/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142001657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to analyze combined intracranial injuries in relation to functional changes in the inner ear, including those of the contralateral ear, in patients with TB fractures. Ninety-four patients (mean age: 35.6 ± 18.7 years, M : F=67 : 27) diagnosed with unilateral TB fracture were included. Bone conduction (BC) threshold, word recognition score (WRS), and changes in vestibular function were compared based on intracranial injuries, focusing on the contralateral side. Various types of intracranial injuries were observed (67.9%). Among these, a significant association between traumatic brain injury (TBI) and otic capsule-violating fractures was noted. The BC threshold on the fractured side significantly deteriorated in patients with TBI. Additionally, a significantly worse BC threshold was confirmed on the contralateral side in patients with TBI, intracranial hemorrhage (ICH), and contrecoup injury. The follow-up BC threshold did not improve or differ, regardless of high-dose steroid administration. The initial WRS and canal paresis in the bithermal caloric test were not significantly different in the presence of each intracranial injury. Concurrent fluctuations in the pressure of the cerebrospinal fluid space and perilymphatic space were speculated to be the potential underlying mechanisms. A significantly worse BC threshold was confirmed on the contralateral side of patients with TBI, contrecoup injury, ICH, and on fracture sides of patients with TBI.","PeriodicalId":94238,"journal":{"name":"The journal of international advanced otology","volume":"20 3","pages":"210-215"},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11232058/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142001658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the ability of physicians to detect fixation suppression using a nystagmus simulation model.Methods: We used a nystagmus simulator to measure the accuracy of the nystagmus fixation suppression test. Fixation suppression was assessed randomly in 6170 trials by 20 otorhinolaryngologists and neurologists, segregated into 2 groups based on their neurootological experience, a beginner and an experienced group. The simulator presented random nystagmus slow velocity (SPV) reductions and presented 3 conditions with either changed nystagmus frequency, amplitude, or both.Results: The cutoff for the discernment of fixation suppression ranged from 1.2 to 14°/s nystagmus velocity difference. The more intense the baseline nystagmus was, the more difficult was the detection of fixation suppression. There was not significant difference (P >.05) in the cutoff values in the experts group compared to the novices for all 3 different conditions. Both, novices and experts, detected frequency changes easier than differences of the nystagmus amplitude. Test sensitivity was very low (19%-65%) for discernment of small nystagmus velocity differences of <2°/s by experts.Conclusion: In our study, there was no difference between experts and novices in detection of nystagmus suppression by visual fixation. The examiners could only detect large suppression effects at low-intensity baseline nystagmus. Overall, the sensitivity and accuracy of a clinical fixation suppression test is low and the assistance with a video-oculography device is highly recommended.","PeriodicalId":94238,"journal":{"name":"The journal of international advanced otology","volume":"20 3","pages":"241-246"},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11232042/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141918488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study aimed to determine if video head impulse testing may be used in such patients as a diagnostic tool. Symptom scoring and treatment efficiency in BPPV are essential parts of the process. Therefore, inventories like \"Dizziness Handicap Inventory\" may be useful in this regard.Methods: Patients with posterior and lateral canal BPPV were included. Video head impulse testing was performed prior to treatment and 1 week after treatment. Vestibuloocular reflex (VOR) gains were noted and compared to the opposite side. The presence of correction saccades was noted as well. Also, pretreatment and posttreatment Dizziness Handicap Inventory scores were compared.Results: Fifty-seven patients were diagnosed with posterior canal BPPV, and sixteen were with horizontal canal BPPV. In patients with posterior canal BPPV, there was no difference between the involved canal VOR gains and the other canals on the same side (P=.639). The involved horizontal canal did not differ from the opposite horizontal canal.

This study investigated the typical characteristics of HL and AR choices in patients diagnosed with IP-II and LVA.Methods: Patients with IP-II and LVA (n=55; 25 women and 30 men) were identified, and audiological evaluations were performed. The patient's demographic characteristics, the type and degree of HL, the AR method, age at diagnosis, and educational status were retrospectively compared.Results: The distribution of our 55 patients according to cochlear implants, hearing aids (HA), and bimodal applications was 29.1% (n=16), 43.6% (n=24), and 27.3% (n=15), respectively. Statistical analyses using chi-square tests found no significant differences in the incidence of dizziness/imbalance, tinnitus, HL progression, or the degree and onset of HL among the patients.Conclusion: The data revealed different audiological characteristics among patients with IP-II and LVA, as well as different AR solutions.
