Hearing head injury

The acute and long-term consequences of mild traumatic brain injury (mTBI) are far reaching. Though it may often be overlooked due to the now expansive field of research dedicated to understanding the consequences of mTBI on the brain, recent work has revealed that substantial changes in the vestibulo-auditory system can also occur due to mTBI. These changes, termed "labyrinthine" or "cochlear concussion", include hearing loss, vertigo, and tinnitus that develop after mTBI in the setting of an intact bony labyrinthine capsule (as detected on imaging)...

Modifiable risk factors for dementia remain prevalent in Ireland. A detailed examination of barriers to risk reduction behaviours in an Irish context has heretofore been lacking. Many existing studies examining barriers to brain health behaviours fail to examine how they might vary across different modifiable risk factors. This study undertook a detailed assessment of barriers to individual risk reduction behaviours. As existing research suggests that barriers may vary across sociodemographic factors, we sought to investigate the distribution of barriers across age, gender, educational status, and household income...

BACKGROUND: Abusive head trauma (AHT) is a major cause of traumatic brain injury in infancy. This exploratory study compared standardized developmental assessment versus functional outcome assessment between 18 months and 5 years of age following AHT in infancy. METHODS: Observational cross-sectional study after surviving AHT in infancy. Seventeen children between 18 months and 5 years of age underwent clinical examination, developmental assessment using the Schedule of Growing Skills II (SGS II) and functional assessment using the Glasgow Outcome Scale-Extended Pediatric Revision (GOS-E Peds)...

UNLABELLED: Trauma to the ear is typically attributed to its location in the craniofacial skeleton. TM is prone to rupture, tear, or perforation when traumatized. Etiological factors may be classified according to the pathogenetic mechanisms (air-pressure change, heat, solids, water pressure). MATERIALS & METHOD: This is a prospective study of 70 patients with traumatic tympanic membrane perforation between January 2019 and December 2022. Inclusion and exclusion criteria applied and results interpreted...

This case report is a follow up of a patient with traumatic brain injury (TBI) post road traffic accident; hearing loss, speech understanding difficulty and tinnitus being the main complaints. CT scan showed brainstem contusion. The diagnosis of retro-cochlear pathology was arrived at after using a test battery approach.

OBJECTIVE: The present study investigated the epidemic of tinnitus in college-aged young adults. Our first objective was to identify health conditions associated with tinnitus in young adults. The second objective was to evaluate the predictive utility of some known risk factors. STUDY DESIGN: A cross-sectional design was used to investigate the prevalence and risk factors for tinnitus. SETTING: A questionnaire was distributed, reaching out to a large college-aged population...

AIMS: Radiation-induced sensorineural hearing loss (RISNHL) is one of the major side effects of radiotherapy (RT) for head and neck cancers. Currently, no effective clinical treatment or prevention is available for RISNHL. This study thus aimed to investigate the cochlear pathology so that the underlying mechanisms of RISNHL may be elucidated, consequently paving the way for potential protective strategies to be developed. RESULTS: Functional and morphological impairment in the stria vascularis (SV) was observed after irradiation (IR), as indicated by endocochlear potential (EP) reduction, hyperpermeability and SV atrophy...

Auditory difficulties reported by normal-hearing Veterans with a history of blast exposure are primarily thought to stem from processing deficits in the central nervous system. However, previous work on speech understanding in noise difficulties in this patient population have only considered peripheral hearing thresholds in the standard audiometric range. Recent research suggests that variability in extended high-frequency (EHF; >8 kHz) hearing sensitivity may contribute to speech understanding deficits in normal-hearing individuals...

PURPOSE: Military risk factors such as blast exposure, noise exposure, head trauma, and neurotoxin exposure place Service members and Veterans at risk for deficits associated with auditory processing dysfunction. However, there is no clinical guidance specific to the treatment of auditory processing deficits in this unique population. We provide an overview of available treatments and their limited supporting evidence for use in adults, emphasizing the need for multidisciplinary case management and interdisciplinary research to support evidence-based solutions...

PURPOSE: Traumatic Brain Injury (TBI) is a major cause of death and disability worldwide. Mounting evidence suggests that even mild TBI injuries, which comprise >75% of all TBIs, can cause chronic post-concussive neurological symptoms, especially when experienced repetitively (rTBI). The most common post-concussive symptoms include auditory dysfunction in the form of hearing loss, tinnitus, or impaired auditory processing, which can occur even in the absence of direct damage to the auditory system at the time of injury...

UNLABELLED: Purpose: To compare the two common approaches of cochlear implantations i.e., mastoidectomy with posterior tympanotomy approach (MPTA) and modified veria technique and to know whether veria technique and its later modifications are as efficacious as the classic approach in terms of duration of procedure, gain in hearing and acquisition and incidence of complications if any. Methods: A prospective comparative study was undertaken at a tertiary care teaching institute. 30 children were selected and randomised into 2 groups who then underwent surgery from the same surgeon after proper evaluation but with 2 different approaches...

Investigating the non-auditory effects of noise on humans has been of interest from different aspects. In this study, the relationship between noise-induced hearing loss (NIHL) and metabolic syndrome. This cross-sectional study was performed on 1380 male workers of one of the oil and gas companies in the south of Iran. The data was obtained via clinical examination and hearing status assessment to evaluate the metabolic syndrome and its components, intravenous blood samples were taken and tested according to NCEPATPIII criteria...

INTRODUCTION: Otomycosis is a fungus-causing superficial infection of the external auditory canal that is common in otolaryngology practice. Though it is a worldwide infection, but is more prevalent in warm and humid regions. There has been rise in the occurrence of otomycosis in the last few years because of the extensive usage of antibiotic eardrops. Other influencing reasons for the occurrence of otomycosis is swimming, an immunocompromised host (e.g.: DM, AIDs) pregnancy, post-canal wall down mastoidectomy, tympanic membrane perforation, hearing aids and self-inflicted injuries...

This study examined the difference in the dynamic visual acuity test (DVAT) between collegiate athletes who are deaf or hard-of-hearing (D/HoH) (n = 38) and university club-level athletes who are hearing (n = 38). Dynamic visual acuity was assessed using the Bertec Vision Advantage (Bertec® Corporation, Columbus, Ohio, USA). No statistically significant differences between athletes who are D/HoH and who are hearing were found in DVAT for leftward (χ2 = 0.71, p = 0...

BACKGROUND: Several treatments for traumatic facial paralysis have been reported, but the role of surgery is still controversial. CASE DESCRIPTION: A 57-year-old man was admitted to our hospital with head trauma due to a fall injury. A total body computed tomography (CT) scan showed a left frontal acute epidural hematoma associated with a left optic canal and petrous bone fractures with the disappearance of the light reflex. Hematoma removal and optic nerve decompression were performed immediately...

There is an increase of firework-related injuries in Germany at the turn of the year. With regard to hearing, a distinction is made between blast (BT) and explosion trauma (ET). The study examines the prevalence and characteristics of firework-related injuries and the impact of the COVID-19-pandemic pyrotechnic ban on New Year's Eve 2020/21 and 2021/22 compared to the 10-year period prior to the pandemic.A retrospective chart review of all patients who presented themselves with the diagnosis blast trauma (H 83...

Necrotizing enterocolitis (NEC) is a devastating condition of multi-factorial origin that affects the intestine of premature infants and results in high morbidity and mortality. Infants that survive contend with several long-term sequelae including neurodevelopmental impairment (NDI)-which encompasses cognitive and psychosocial deficits as well as motor, vision, and hearing impairment. Alterations in the gut-brain axis (GBA) homeostasis have been implicated in the pathogenesis of NEC and the development of NDI...

PURPOSE: Noise-induced hearing loss (NIHL) often results in impaired functional hearing and accidental injuries; thus, reducing military performance and endangering flight safety. While a few studies addressing laterality (left-right ear differences) and NIHL incidence between fixed-winged (jet-fighter) and rotary-wing (helicopter) aircrafts yielded inconsistent results, little is known about the NIHL profile among different types of jet-fighter pilots. This study aims to conduct a fine-grained examination of NIHL among Airforce jet pilots, with planned comparisons of laterality and aircraft type, along with the goal to compare the sensitivity of different hearing indices in predicting military pilot NIHL...
