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...

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

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.

Here we demonstrate a method for inducing and recording the progress of a delayed type-hypersensitivity (DTH) reaction in the rat ear. This is followed by a demonstration of the preparation of rat ear tissue for two-photon imaging of the effector / memory T cell response.
FAQs
Reimplantation is considered when an existing AUS no longer provides a safe or reliable continence result. The stated triggers include infection, urethral erosion, mechanical damage, and loss of effectiveness. These causes represent different failure problems, but each can make continued reliance on the implanted system unsuitable. Identifying the reason for failure helps frame revision as both device restoration and complication management.
The three AUS components must function as a coordinated pressure system. The cuff provides urethral compression, the balloon regulates pressure, and the pump changes the cuff state during voiding. A problem in any component can disrupt the sequence that supports continence or urination. During reimplantation, restoring this coordinated system is therefore central to recovering the intended device function.
Scar tissue is a major consideration because reimplantation takes place in tissue altered by the earlier implant or its complication. The overview specifically identifies scar management as part of this specialized revision procedure. Addressing that tissue context matters for restoring the system while also attempting to reduce the chance of additional complications. The procedure is consequently more complex than simply supplying a new device.
Infection and erosion are clinically important reasons for AUS reimplantation because they involve more than loss of mechanical performance. Infection indicates a device-related complication, while erosion means the cuff has affected urethral tissue. Mechanical damage and ineffectiveness instead emphasize system failure or inadequate continence. Distinguishing these problems gives revision a different purpose: managing the complication as well as addressing urinary leakage.
Reimplantation may replace a failed system or restore an AUS after a complication, but the objective is not limited to inserting hardware. The procedure must account for the underlying reason for failure, the condition of surrounding tissue, and the need to limit further complications. Its intended outcome is improved continence through a functioning system, while recognizing that revision occurs in a more challenging surgical setting.
The main clinical context is stress urinary incontinence in men, particularly when it follows prostate surgery and an earlier AUS requires revision. In this setting, reimplantation offers a way to pursue continence after infection, erosion, mechanical damage, or declining effectiveness has compromised the original result. Its relevance lies in combining continence treatment with management of a failed or complicated implant.
