Hearing loss following a head injury is common and well known. The numbers of road traffic accidents have increased recently, with minor head injuries being very common, and usually go unreported. Hearing loss after a minor head injury is often unnoticed. Available literature is limited in this regard. This study was done to assess hearing loss in patients with minor head injuries and to define its natural history and progression/regression by a serial assessment of hearing. This prospective study was done in the Department of Neurosurgery, AIIMS, Bhubaneshwar, Odisha, India, for a period of 24 months to look at the profile of hearing levels of patients presenting with history suggestive of minor head injury. This study has shown that some form of hearing loss is common after a minor head injury and should be evaluated in all patients to detect subclinical hearing loss. A significant number of patients having minimal or a mild degree of hearing loss, if managed properly, improve to preinjury status. Distortion product oto-acoustic emission testing should be used as the screening and follow-up tool. This study highlights the importance of hearing assessment in minor-head-injury patients and the prognosis of recovery as per the severity of hearing loss and head injury.

Sensorineural hearing loss (SNHL) is characterized by a compromised cochlear perception of sound waves. Major risk factors for SNHL include genetic mutations, exposure to noise, ototoxic medications, and the aging process. Previous research has demonstrated that inflammation, oxidative stress, apoptosis, and autophagy, which are detrimental to inner ear cells, contribute to the pathogenesis of SNHL; however, the precise mechanisms remain inadequately understood.

Background: Hearing loss (HL) is a common sensory disorder in humans. Studies on the relationship between arsenic, which is a highly toxic and widely distributed heavy metal with a health risk to humans, and hearing status in humans are contradictory and mostly focused on people living in arsenic-contaminated areas. This study investigated the association between urinary arsenic levels and hearing threshold shifts in the general population in the United States.

Autoimmune inner ear disease (AIED) is a rare condition characterized by immune-mediated damage to the inner ear, leading to progressive sensorineural hearing loss (SNHL) and vestibular symptoms such as vertigo and tinnitus. This study investigates the pathogenesis and therapeutic strategies for AIED through the analysis of three cases with different underlying autoimmune disorders: rheumatoid arthritis, relapsing polychondritis, and IgG4-related disease. The etiology of AIED involves complex immunopathological mechanisms, including molecular mimicry and the "bystander effect," with specific autoantibodies, such as those against heat shock protein 70 (HSP70), playing a potential role in cochlear damage.

Background: A vestibular implant can partially restore vestibular function by providing motion information through implanted electrodes. During vestibular implantation, various obstructions of the semicircular canals, such as protein deposits, fibrosis, and ossification, can be encountered. The objective was to explore the relationship between preoperative imaging and intraoperative findings of semicircular canal obstruction and to develop surgical strategies for dealing with obstructions of the semicircular canal(s) in patients eligible for vestibular implantation.

Article Synopsis
- Oral submucous fibrosis (OSMF) is a serious condition associated with areca nut chewing, linked to dental health and possibly hearing impairment, prompting a need for investigation into its effects on hearing.
- A systematic review of 1137 articles identified 18 studies showing a significant correlation between OSMF severity and hearing loss, particularly conductive hearing loss in advanced cases.
- The review highlighted that Eustachian tube dysfunction (ETD) often contributes to hearing issues in OSMF patients, emphasizing the importance of multidisciplinary management and early audiological screening for better patient outcomes.
