Clinical Predictors of Pulsatile Tinnitus in Patients With Idiopathic Intracranial Hypertension: An Age-Matched Cohort Study.

INTRODUCTION: Pulsatile tinnitus (PT) occurs in many but not all patients with idiopathic intracranial hypertension (IIH). It is poorly understood why some patients with IIH develop PT, yet others do not. The purpose of this study was to determine if any clinical findings differ between those with and without PT in IIH, potentially shedding light on a pathophysiologic mechanism. METHODS: Age-matched cohort analysis of patients with documented IIH and presence or absence of PT was performed, collecting data including body mass index (BMI), blood pressure, visual acuity, cerebrospinal fluid (CSF) opening pressure, sleep apnea, migraines, and transient visual obscurations, among others. Independent-sample t test and χ2 test were used to analyze continuous and binary variables, respectively, with multivariate analysis conducted including variables statistically significant on univariate analysis. RESULTS: Eighty subjects with IIH met the inclusion criteria (40 PT+, 40 PT-). CSF opening pressure showed no significant difference between the two groups. The PT+ cohort was found to have an average BMI of 45.1 kg/m 2 , which was significantly higher than the PT- group (37.7 kg/m 2 ; p = 0.0023). PT+ pulse pressure (60.1 mm Hg) was also significantly higher than the PT- group (51.6 mm Hg; p = 0.019). PT+ patients were also significantly more likely to have sleep apnea ( p < 0.001) and migraines ( p = 0.0036). Multiple logistic regression revealed an adjusted odds ratio of 13.9 for sleep apnea, 4.1 for migraines, and 1.01 for every increase in unit of BMI. CONCLUSION: Among patients with IIH, presence of PT is associated with higher BMI and pulse pressure, and increased incidence of sleep apnea and migraines. Given no significant difference in CSF pressures between the two groups, PT may not be a product of increased disease severity but may be related to sequelae of obesity, such as increased pulse pressure and sleep apnea.

Comparing surgeon perception to publicly reported data using NSQIP.

Background: Past studies have demonstrated that surgeons' perceptions of their own postsurgical complications may not be accurate. The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database is a nationally validated, risk-adjusted, outcomes-based program created to measure and improve the quality of surgical care. Using information acquired through survey data, the purpose of this study is to determine how surgeons' perceptions of their own postoperative complications rates compare to the NSQIP database that tracks these outcome metrics. Hypothesis/purpose: We hypothesize that surgeons underestimate their rates of morbidity, readmission, and reoperation within thirty days postoperatively when compared to NSQIP data. Study design: Data elements such as perceived morbidity, readmission, and reoperation were collected through surveys distributed at a large level one trauma center. Survey respondents were asked how their rates compared to their peers and physician survey responses were then compared to institutional NSQIP data. Results: 87.5% of surgeons underestimated their rates of morbidity, 35.4% underestimated their rates of readmission, 22.9% underestimated their rates of reoperation. When comparing themselves to their departmental averages, 57.78% accurately estimated their morbidity rates, 75.56% accurately estimated readmission rates, and 86.67% accurately estimated reoperation rates. Conclusion: Surgeons are poor predictors of individual 30-day postoperative complication rates including morbidity, readmission, and reoperation. However, surgeons are more accurate in estimating these same outcomes when asked to compare to the average of their department.

A Novel Approach to Improving Post-Operative Pain and Minimizing Opioid Consumption After a Hip Arthroscopy.

Background: There have been many different approaches to controlling pain in patients undergoing hip arthroscopy. These include medications, nerve blocks, and intra-articular injections among many others. We introduced a combination of a pre-operative pericapsular nerve group (PENG) block, and intra-operative pericapsular injection of BKK (bupivacaine, ketamine, and ketorolac). Methods: Patients undergoing primary hip arthroscopy were identified. There were three patient cohorts based on type of anesthesia: general anesthesia only (GA), general anesthesia and a pericapsular Marcaine injection (GA/Marcaine), or GA with pre-operative PENG block and an intraoperative BKK pericapsular injection (GA+PENG/BKK). Data collected included post-operative pain scores in the PACU (Post-Anesthesia Care Unit), time spent in the PACU, inpatient opioid consumption (both PACU and inpatient), and outpatient opioid prescriptions filled. Results: 20 patients received GA, 11 patients received GA/Marcaine, and 20 patients received GA+PENG/BKK. The GA+PENG/BKK group had average PACU pain score of 3.9 out of 10 compared to 7.7 in the GA group (p<.001) and 6.6 in the GA/Marcaine injection group (p=.048). The GA+PENG/BKK group had shorter mean PACU times than either other group (p<.001). The GA+PENG/BKK also consumed less opioids than the GA or GA/Marcaine groups in the PACU (p<.001), and in the total inpatient stay (p=.002, p=.003), as well as outpatient (p=.019, p=.040). Conclusion: In patients undergoing a hip arthroscopy, performing a pre-operative PENG block and intra-operative BKK pericapsular injection will result in decreased postoperative pain, PACU time, and inpatient and outpatient opioids compared to general anesthesia only and general anesthesia with intracapsular Marcaine.

Magnetic Resonance Imaging Findings in Idiopathic Intracranial Hypertension With and Without Pulsatile Tinnitus: An Age-Matched Cohort Study.

OBJECTIVE: Many but not all patients with idiopathic intracranial hypertension (IIH) have pulsatile tinnitus (PT). However, little is known about why some patients with IIH develop PT and others do not. The purpose of this study was to determine if any of the classic magnetic resonance imaging (MRI)-detectable markers of IIH differ between patients with and without PT, thereby shedding light on potential pathophysiology. METHODS: A retrospective age-matched cohort study of patients with documented IIH (diagnosed by neuro-ophthalmologist) was performed. All patients had MRI performed around the time of diagnosis. MRIs were assessed for 16 variables known to be associated with IIH (e.g., pituitary displacement/empty sella, optic nerve tortuosity, transverse sinus stenosis, inferior cerebellar tonsils, arachnoid granulations, slit-like ventricles) by two blinded neuroradiologists. All binary variables were analyzed via χ2 test with Yates correction, or Fisher exact when appropriate. Continuous variables were analyzed via Student t test. Inter-rater reliability for binary variables was assessed by Cohen κ . For continuous variables, intraclass correlation coefficient was calculated. RESULTS: Forty age-matched patients with IIH met the inclusion criteria (20 with PT, 20 without PT). For all known binary MRI findings associated with IIH, there were no statistically significant differences between groups. Likewise, there were no statistically significant differences for continuous variables. CONCLUSIONS: The classic MRI findings associated with IIH do not differ between patients with and without PT, suggesting that systemic (rather than localized intrinsic or extrinsic) factors may play a critical role in the pathophysiology.

The Lasting Impact of the COVID-19 Pandemic on Surgical Key Indicator Cases for Otolaryngology Residency Education.

OBJECTIVES: Early on during the COVID-19 pandemic, the US Centers for Medicare & Medicaid Services (CMS) and other government as well as medical institutions recommended that surgeons postpone nonessential surgeries. The aim of our study is to examine the impact of the COVID-19 pandemic on otolaryngology surgical training by evaluating changes in surgical volumes through various time points relative to the height of the pandemic. METHODS: We performed a retrospective review of all surgical cases performed by the Otolaryngology-Head and Neck Surgery department at a tertiary care academic center from 3 time periods: July 1st, 2018, to June 30th, 2019; July 1st, 2019, to June 30th, 2020; and July 1st, 2020, to June 30th, 2021. RESULTS: From the 2018-19 period to the 2020-21 period, the total number of overall cases decreased by 9.9%, from 2386 to 2148 cases. During this same time duration, the number of key indicator cases decreased by 13.4%, from 1715 to 1486 cases. Relative to other cases, ethmoidectomy, rhinoplasty, and stapes/OCR cases decreased the most during the 2019-20 period by 41.9%, 41.8%, and 29.5%, respectively. From the 2018-19 period to the 2020-21 period, thyroid/parathyroid cases decreased the most by 35.4%. Only ethmoidectomy and oral cavity cases showed increases during this period at 9.7% and 24.4%, respectively. CONCLUSIONS: Although case volumes have stayed relatively constant, key indicator case volumes at the present tertiary care academic center have not yet fully recovered from the COVID-19 pandemic. Efforts must be made to determine how this has impacted residency surgical education.

Return to Football after a Cervical Disk Arthroplasty: A Case Report.

Introduction: Symptomatic cervical spine disk hernations in high-level athletes are traditionally treated with anterior cervical disk fusion (ACDF) after failed conservative management. Unfortunately, an ACDF comes with decreased mobility and only a return to sport 73.5% of the time. In high-level athletes, mobility and range of motion can be critical to their long-term success. This case report will discuss the successful treatment of a C6-C7 disk herniation with a cervical disk replacement (CDR). Case Report: This is a 23-year-old football player whom had a left paracentral C6-C7 disk herniation causing foraminal stenosis. He had significant triceps muscle wasting and weakness and he was not able to participate in football secondary to his symptoms. After failing 6 weeks of conservative, he underwent a CDR. At 8 weeks postoperatively, he was cleared for football and return to sport without complications. Conclusion: The CDR provides high-level athletes the ability to return to contact sports safely. In this unique case, we present a division one football player with a symptomatic cervical herniated disk that was treated with a CDR and return to sport without any limitations or complications. The CDR was able to treat symptoms, improve strength and motion, and ultimately allow the player to return to football. More studies need to be performed, but ultimately CDR in athletes can get them back on the field, improve their cervical range of motion, and decrease their risk of adjacent segment disease in the long run when compared to the cervical fusion.
