Aim: To evaluate the effect of blast injury on the otologic and hearing state over time.
Setting: Otology unit of a tertiary referral center.
Methods: Seventy-three patients aged 16 to 73 years who sustained physical trauma from an explosion underwent otologic and audiologic examination 3-4 months and one year later.
Results: At the first examination, high-frequency sensorineural hearing loss was detected in 57 patients (78%), mixed hearing loss in 13 (19%), and low-tone conductive hearing loss in two (3%). Conductive hearing loss had improved by one year, while the cochlear hearing loss, in most cases, did not. Only 7% of the patients with tinnitus reported improvement after one year.
Conclusions: The permanent otologic damage caused by blast injury cannot be determined before one year after the traumatic event.

Background: Childhood hearing loss (CHL) is a condition that can have a variety of causes, including genetic and environmental and its prevalence is thought to be high in Saudi Arabian population mainly due to consanguineous unions. This systematic literature review aims to conclude the prevalence of hereditary hearing loss and its risk factors among the Saudi population.

Postoperative dizziness after cochlear implant surgery: can it be caused by air?

Department of Otorhinolaryngology, Medical Center - University of Freiburg, Faculty of Medicine, University of Freiburg, Freiburg, Germany.
Objectives: Multiple studies have described the onset and variable incidence of postoperative acute vertigo following cochlear implant (CI) surgery. However, postoperative imaging has not yet been specifically evaluated with special focus on vertigo. The aim of this study is to assess the incidence and causes of new-onset, acute postoperative vertigo following CI surgery using cone beam computed tomography (CBCT).

Attempts to treat mouse models of DFNB1 with AAV vectors mediating nonspecific expression have not substantially restored function, perhaps because inappropriate expression in hair cells and neurons could compromise their electrical activity.

The defining feature of -SWN is the presence of bilateral vestibular schwannomas (VSs), which grow over time and can result in irreversible sensorineural hearing loss, significantly affecting the quality of life for those affected. At present, there are no FDA-approved medications specifically for treating VS or related hearing loss.
