SSNHL is likely associated with vascular insufficiency; however, no study has evaluated the relationship between dehydration and SSNHL. Objective: This study aimed to investigate the role of dehydration in the development and prognosis of sudden sensorineural hearing loss. Study Design: Retrospective case-control study. Setting: Secondary referral hospital. Patients and Interventions: This was a comparative study that compared dehydration parameters between healthy subjects without SSNHL (n = 94) and patients with SSNHL (n = 94). The study also evaluated the effect of dehydrated conditions on the prognosis of SSNHL. Main Outcome Measures: We compared dehydration parameters, such as the blood urea nitrogen-to-creatinine ratio (BUN/Cre) and plasma osmolality (Posm), between matched healthy subjects without SSNHL and patients with SSNHL. To evaluate the effect of dehydrated conditions on the SSNHL prognosis, the SSNHL patients were divided into 2 groups based on the cutoff value obtained from the receiver operating characteristic analysis: hydrated (n = 50; BUN/Cre <21.4) and dehydrated (n = 44; BUN/Cre ≥21.4) groups. Subsequently, the severity and prognosis of SSNHL were analyzed. Results: The dehydration parameters, BUN/Cre and Posm, were significantly higher in patients with SSNHL than in healthy subjects. The initial hearing levels and SSNHL grades were worse in the dehydrated group than in the hydrated group. Moreover, a dehydrated condition (BUN/Cre ≥21.4) was associated with a poor SSNHL prognosis in all models of the multiple logistic regression analysis. Conclusions: The dehydration parameters of BUN/Cre and Posm were higher in patients with SSNHL than in healthy subjects. Additionally, a dehydrated condition (BUN/Cre ≥21.4) was an independent prognostic factor for SSNHL. Level of evidence: Level 4.","PeriodicalId":74382,"journal":{"name":"Otology & neurotology open","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136360532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients: A 64-year-old woman presented with right-sided aural fullness, pulsatile tinnitus, and intermittent otalgia. Interventions: CT and MRI were performed without contrast and suggested an osseodestructive, lytic bone lesion. An excisional biopsy was performed, showing granulomatous infiltration suggestive of osseous sarcoidosis. Main Outcome Measures: Removal of mass and resolution of symptoms. Results: Initial findings from patient imaging suggested a lytic bone lesion. An excisional biopsy was required for diagnosis and was performed with little patient morbidity. Biopsy findings showed granulomatous infiltration suggestive of osseous sarcoidosis. Osseous involvement of sarcoidosis is a rare manifestation and typically occurs secondary to other disease manifestations. After the removal of the mass and a short unrelated course of steroids, the patient’s symptoms resolved. Conclusions: Sarcoidosis should be added to the differential diagnosis of lytic bone lesions in the temporal bone.","PeriodicalId":74382,"journal":{"name":"Otology & neurotology open","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135255372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Study design and setting: Retrospective study in a tertiary referral center. Patients: Fifty-one VS patients were included (34 females;17 males), aged from 41 to 78 years treated exclusively with SRS. Intervention: Vestibular function was assessed before SRS and with median time interval of 14 (FU1) and 25 (FU2) months after treatment. Vestibular evaluation included: history, clinical vestibular examination, videonystagmography, head impulse test (v-HIT) and cervical vestibular evoked myogenic potentials (c-VEMPS). Results: Before SRS, caloric testing (Caloric) was impaired in 77%; after treatment, in 92% (FU1) and 77% (FU2). Lateral HIT was decreased in 22% before SRS, in 39% at FU1 and FU2. C-VEMPS were absent in 50% before SRS, in 76% at FU1 and, FU2. Before SRS, no statistically significant association was found between asymptomatic and symptomatic patients with respect to the results of Caloric, v-HIT and c-VEMPS. This lack of association was also seen after SRS, at FU1 and FU2. Conclusion: Our study showed that the impairment of the vestibular function might be attributed to the VS itself as well as to the radiation of the inner ear during SRS. The lateral SSC at low frequencies and the saccular function seem to be more involved with the time.","PeriodicalId":74382,"journal":{"name":"Otology & neurotology open","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135255223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This raises the question of how we developed our ideas about vestibular migraine and how these ideas shape how we treat it. This review walks through the history of how our conceptualization of migraine and vestibular symptoms evolved, starting with clinical observations in ancient times, inclusion under the umbrella of Meniere’s disease, and then separation from Meniere’s disease with its own identity. Tradition, clinical observations, and diagnostic criteria developed by professional societies have played prominent roles in building our current concept of vestibular migraine. A review of the ideas that have shaped our current conception of vestibular migraine may help us to see which ones have stood the test of time and which ones should continue to evolve.
