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...

Canalostomy for Local Drug Delivery into the Inner Ear of an Adult Mouse

2025
This video showcases canalostomy, a procedure that allows local drug delivery into the inner ear of a mouse through the semicircular canal with minimal damage to hearing and vestibular function. This method enables the inoculation of viral vectors, pharmaceuticals, and small molecules into the mouse's inner ear.
FAQs
The affected structure and cause of disease guide treatment selection. Damage centered on the tympanic membrane may call for tympanoplasty, while disrupted sound transmission through the ossicles may require ossiculoplasty. When diseased tissue and chronic infection are involved, mastoidectomy may be considered. Matching the procedure to the anatomy helps target the abnormality while preserving useful middle ear function.
Improving Eustachian tube ventilation can support the middle ear environment when inadequate ventilation contributes to related disorders. This approach differs from directly repairing the tympanic membrane or reconstructing the ossicles because it addresses pressure and ventilation rather than structural sound transmission alone. The goal is to create conditions that support healing, reduce persistent inflammation, and improve middle ear function.
These procedures target distinct components of disease. Tympanoplasty repairs the tympanic membrane, ossiculoplasty reconstructs or replaces ossicles to improve sound transmission, and mastoidectomy removes diseased tissue when infection or related disease requires it. Because hearing loss and chronic infection can arise from different abnormalities, the procedures may be selected individually or combined according to the patient's anatomy and condition.
Planning begins by relating the patient's hearing loss, chronic infection, or other disorder to the involved anatomy. Surgeons then determine whether treatment should remove diseased tissue, repair the tympanic membrane, reconstruct the ossicles, improve Eustachian tube ventilation, or use a combination of these approaches. Protecting the inner ear remains an important consideration while addressing the primary problem.
Mastoidectomy may be selected when diseased tissue or chronic infection is a central concern, rather than when the main abnormality is limited to the tympanic membrane or ossicles. In that setting, removing affected tissue can help control the disease process. Tympanoplasty or ossiculoplasty may instead be more appropriate when the principal goal is repairing a membrane or restoring sound transmission.
Evaluation can focus on whether the operation controlled inflammation or infection, improved sound transmission, and supported hearing rehabilitation. Outcomes depend on the original cause and the structures treated, so anatomic repair and functional hearing may both matter. Protecting the inner ear is also relevant because successful treatment should address the middle ear disorder without creating additional harm to inner ear function.
