Objectives: Vitamin D deficiency as a risk factor of tinnitus has not been well known. We tried to evaluate the association between the serum 25-(OH) vitamin D levels and tinnitus among the Korean population to propose the possible role of serum vitamin D in patients with tinnitus., Methods: This cross-sectional study investigated the potential risk factors of tinnitus in relation to serum 25(OH)D levels within the Korean population. It encompassed a health interview, nutrition assessment, and a health examination. Data was sourced from the KNHANES V (2010-2012), conducted by the Division of Health and Nutritional Survey under the Korean Centers for Disease Control and Prevention (KCDCP). Participants were chosen from various sampling units categorized by geography, gender, and age group. The selection was facilitated through household registries using a stratified, multistage, clustered probability sampling approach., Results: Data of 16 408 subjects were collected in this study. There were significant differences in gender, economic status, educational level, and sun exposure duration between the tinnitus and non-tinnitus groups. Serum 25(OH) vitamin D level between hearing loss and normal hearing was also significantly different. The logistic regression models with serum 25(OH) vitamin D quartile and tinnitus as the dependent variable, which were controlled for age, sex, smoking status, BMI, diabetes, hypertension, sun exposure, regular exercise, income, and education, eventually demonstrated that serum vitamin D deficiency and low sun exposure duration significantly increased the risk of tinnitus development., Conclusion: This study demonstrated a significant association between serum vitamin D levels and tinnitus, driven by large epidemiological data. The results of our study provide baseline data for further research to investigate the role of vitamin D in the pathogenesis and management of tinnitus., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objective: Review of a sigmoid sinus diverticuli (SSDi) variants surgically managed with a novel technique using an inferior periosteal flap., Study Design: Case series., Setting: Tertiary referral center., Patients: Patients presenting with pulsatile tinnitus to a tertiary referral center between January 1, 2015, and June 31, 2021, who were diagnosed with SSDi variants on CT temporal bone and who received surgical management for these SSDi variants., Interventions: Obliteration of SSDi variants using a novel technique with an inferiorly based periosteal flap., Main Outcome Measures: Pure-tone audiometry, Tinnitus Handicap Inventory score, and visual analogue scale score for tinnitus severity (loudness, awareness, annoyance, and effect on life)., Results: Include statistical measures as appropriate., Conclusions: We would like to propose the use of an inferiorly based periosteal flap as an option for obliteration and concomitant hemostasis of more sizeable or complex (e.g., bifid) SSDi. Further study of this technique with a long-term follow-up will be needed to evaluate its long-term safety and efficacy., Competing Interests: Conflict of interest statement: The authors disclose no conflicts of interest., (Copyright © 2023, Otology & Neurotology, Inc.)
