Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA This video describes the examination of the ear, beginning with a review of its surface and interior anatomy (Figure 1). The cartilaginous auricle consists of the helix, antihelix, earlobe, and tragus. The mastoid process is positioned just behind the earlobe. The slightly curving auditory canal ends at the tympanic membrane, which transmits sound...

Acute brain trauma is a severe injury that has no adequate treatment to date. Multiphoton microscopy allows studying longitudinally the process of acute brain trauma development and probing therapeutical strategies in rodents. Two models of acute brain trauma studied with in vivo two-photon imaging of brain are demonstrated in this protocol.

FAQs
The injury pathway depends on the exposure: excessive noise, rapid pressure changes, head injury, and certain medications can affect inner-ear structures through different circumstances. Despite these differences, damage may disrupt sensory hair cells or their neural connections, impairing the transmission of auditory or vestibular signals. Recognizing the exposure pattern helps clinicians interpret subsequent hearing or balance problems.
Sensory hair cells and their neural connections are essential links in transmitting auditory and vestibular information. When either is injured, signals may no longer be conveyed normally, even if the original exposure has ended. This disruption explains why affected patients can experience hearing loss, tinnitus, dizziness, or vertigo, and why functional limitations may persist.
The symptoms depend on which inner-ear functions are disrupted. Problems involving auditory signaling may appear as hearing loss or tinnitus, while disruption of vestibular signaling may produce dizziness or vertigo. Because hearing and balance functions can be affected separately or together, a patient may show an isolated sensory complaint or a combination that limits everyday function.
Evaluation should include timely audiologic and vestibular assessment because inner ear trauma can disturb hearing, balance, or both. Audiologic assessment addresses auditory function, while vestibular assessment addresses balance-related effects. Considering both domains helps characterize the patient’s functional impairment and provides information needed to guide subsequent medical or rehabilitative management.
Assessment findings help guide medical or rehabilitative management rather than relying only on the reported exposure. The approach must account for whether the main functional problem involves hearing, balance, or both, and whether limitations persist. This distinction supports a more appropriate response to the patient’s specific impairment and helps address ongoing effects on daily function.
Prevention is particularly relevant in occupational, military, emergency, and clinical settings, where recognized causes such as excessive noise, rapid pressure changes, head injury, or medication-related effects may be encountered. Applying prevention strategies in these environments can reduce the likelihood of exposure-related inner-ear damage and help limit later hearing, balance, or functional problems.
