Background and Objectives: This study aimed to comprehensively assess the factors influencing hearing ability in patients with vestibular schwannoma, focusing on tumor size, location, primary complaint, and contralateral hearing threshold.Subjects and Method This was a retrospective analysis of 50 patients diagnosed with vestibular schwannoma by magnetic resonance imaging (MRI) at Nowon Eulji Medical Center. Tumor size and location were evaluated using a 3-T MRI system, and pure-tone threshold and speech discrimination were retrieved. To investigate the relationship between tumor size and hearing, we conducted a multiple regression analysis with several variables, including tumor size, tumor location, patient age, and gender. Results: When patients were categorized into groups according to their primary complaint at initial presentation, no significant differences were observed in pure tone thresholds but different speech discrimination were detected among the groups. When patients were classified according to the tumor location, the extrameatal group exhibited lower pure-tone thresholds and higher speech discrimination scores than the intrameatal group. Multiple regression analysis indicated that differences in pure tone thresholds and speech discrimination scores between affected and unaffected sides were more pronounced in cases with smaller tumor sizes and extrameatal tumor locations, emphasizing the greater impact of location over size. Conclusion Using both tumor size and location, it is possible to predict the differences in pure-tone thresholds and speech discrimination between the affected and unaffected sides. Extrameatal invasion of the tumor appears to be the most important factor among them.

Background: Increasing longevity has caused the very old population to become the fastest-growing segment. The number of centenarians (over 100 years old) is increasing rapidly. Fractures in the elderly lead to excessive medical costs and decreased quality of life with socioeconomic burdens. However, little research has thoroughly examined the functional outcomes and mortality of hip fractures in centenarians. Methods: This is a retrospective observational study. Sixty-eight centenarian hip fracture patients were admitted to the 10 institutions from February 2004 to December 2019. Fifty-six patients with 1-year follow-up were finally included. The following data were obtained: sex, age, body mass index, Charlson comorbidity index value on the operation day, Koval’s classification for ambulatory ability, type of fracture, the time interval from trauma to surgery, American Society of Anesthesiologists grade, surgery-related complications, and duration of hospital stay. Postoperative Koval’s classification (at 1 year after surgery) and information about death were also collected. Multivariate analysis was performed to analyze the risk factors affecting mortality 1 year after surgery. Results: Mortality rates were 26.8% at 6 months and 39.3% at 1 year. The 90-day mortality was 19.6%, and one of them (2.1%) died in the hospital. The 1-year mortality rates for the community ambulatory and non-community ambulatory groups were 29% and 52%, respectively. Only 9 (16.1%) were able to walk outdoors 1 year after surgery. The remaining 47 patients (83.9%) had to stay indoors after surgery. Multivariate analysis demonstrated that the pre-injury ambulatory level (adjusted hazard ratio, 2.884; p = 0.034) was associated with the risk of mortality. Conclusions We report a 1-year mortality rate of 39.3% in centenarian patients with hip fractures. The risk factor for mortality was the pre-injury ambulatory status. This could be an important consideration in the planning of treatment for centenarian hip fracture patients.
