“…Unfortunately, many of these studies incorporated a range of TBI categories from mild to severe and may have included patients with temporal bone fractures. TBI can occur in mild, moderate, and severe forms, and nonspecific inclusion of patients with all types of TBI without discussion of temporal bone fracture makes interpretation and generalization of these studies challenging …”

“…TBI can occur in mild, moderate, and severe forms, and nonspecific inclusion of patients with all types of TBI without discussion of temporal bone fracture makes interpretation and generalization of these studies challenging. 14,[41][42][43] Beyond the civilian literature, research has been completed in military personnel who sustained blast-related TBI and/or acoustic trauma. Hearing loss and tinnitus are the two most prevalent service-connected conditions in this sample population.…”

Objectives/Hypothesis Few studies have specifically addressed auditory complaints in patients with nonblast mild traumatic brain injury (mTBI). Herein, we aimed to investigate auditory symptoms in patients following mTBI using patient‐reported outcome measures. Study Design Retrospective analysis of prospectively collected data in a tertiary‐care hospital. Methods The patients included those with mTBI (cases) and those without mTBI (controls). Individuals (≥18 years old) with and without mTBI were screened. Exclusion criteria included history of otologic disorders, blast injury, or occupational noise exposure. Primary outcomes included the Hearing Handicap Inventory for Adults (HHIA), Tinnitus Handicap Inventory (THI), and Hyperacusis Questionnaire (HQ). Secondary outcomes included subjective auditory complaints. Results From September 2017 to September 2018, 52 patients with mTBI and 55 controls met inclusion and exclusion criteria. The mean time between mTBI and survey intake was 70.6 months. The mean age and gender were 51.5 years old and 73% female in the mTBI group, and 46.1 years old and 56.3% female in the control group (P = .112 and P = .105, respectively). Patients with mTBI reported hyperacusis (67.3% of all mTBI patients), hearing loss (61.5%), and tinnitus (61.5%), compared to 8.3%, 12.7%, and 16.4%, respectively, for control subjects (P < .0001). The mean HHIA score in the mTBI group was 38.3 versus 8.5 in controls (P = .002). The mean THI score was 27.4 in the mTBI group and 3.1 in controls (P < .0001). The mean HQ score was 26.5 in mTBI group and 7.3 in controls (P = .001). Conclusions Auditory symptoms and associated handicap were common in patients with nonblast mTBI compared to age‐matched controls. Findings have implications for the pathophysiology and management of symptoms in this patient population. Level of Evidence 3 Laryngoscope, 130:761–767, 2020

“…Schuknecht's above-mentioned study with cats confirmed the most common hearing loss to occur was a sensorineural hearing loss with notching at 3–8 kHz—quite similar to what is seen with occupational noise-induced hearing loss. A recent review of the Taiwan National Health Insurance Database of 553,286 TBI patients, compared to 1.1 million patients without TBI, demonstrated a 2.125x increased risk of hearing loss among the TBI patients ( 8 ). The most common source of trauma was a motor vehicle accident.…”

Post-concussive Dizziness: A Review and Clinical Approach to the Patient

Dizziness is a frequent complaint after head trauma. Among patients who suffer a concussion (mild traumatic brain injury or mTBI), dizziness is second only to headache in symptom frequency. The differential diagnosis of post-concussive dizziness (PCD) can be divided into non-vestibular, central vestibular and peripheral vestibular causes with growing recognition that patients frequently exhibit both central and peripheral findings on vestibular testing. Symptoms that traditionally have been ascribed to central vestibular dysfunction may be due to peripheral dysfunction. Further, our ability to test peripheral vestibular function has improved and has allowed us to identify peripheral disorders that in the past would have remained unnoticed. The importance of the identification of the peripheral component in PCD lies in our ability to remedy the peripheral vestibular component to a much greater extent than the central component. Unfortunately, many patients are not adequately evaluated for vestibular disorders until long after the onset of their symptoms. Among the diagnoses seen as causes for PCD are (1) Central vestibular disorders, (2) Benign Paroxysmal Positional Vertigo (BPPV), (3) Labyrinthine dehiscence/perilymph fistula syndrome, (4) labyrinthine concussion, (5) secondary endolymphatic hydrops, (6) Temporal bone fracture, and (7) Malingering (particularly when litigation is pending). These diagnoses are not mutually exclusive and PCD patients frequently exhibit a combination of these disorders. A review of the literature and a general approach to the patient with post-concussive dizziness will be detailed as well as a review of the above-mentioned diagnostic categories.

The NHI program covers 99.9% of the 23.74 million people residing in Taiwan [ 5 , 6 ].

The aim of study is to investigate the risk of developing acquired cholesteatoma and external auditory canal (EAC) stenosis after traumatic brain injury (TBI) from the Taiwan National Health Insurance Research Database (NHIRD). Each subject was individually traced from their index date to identify those who received a diagnosis of acquired cholesteatoma and EAC stenosis. Cox regression analyses were applied to determine the risk of TBI-related acquired cholesteatoma and EAC stenosis. The follow-up data collected over 10 years were obtained from the TBI and comparison cohorts, of 455,834 and 911,668 patients, respectively. Multivariate analysis demonstrated that TBI significantly increased the risk of cholesteatoma (adjusted hazard ratio (HR), 1.777; 95% confidence interval (CI), 1.494−2.114, p < 0.001) and EAC stenosis (adjusted (HR), 3.549; 95% (CI), 2.713−4.644, p < 0.001). In our subgroup injury analysis, falls had the highest associated risk (4.308 times), followed by traffic injuries (66.73%; 3.718 times that of the control group). Otolaryngologists should not neglect the clinical importance and carefully investigate the possibility of subsequent cholesteatoma and EAC stenosis, which leads to hearing impairment in patients with TBI. Our research also shows the important role in preventing TBI, especially as a result of traffic injuries and falls.
