要旨

Background:

Improved surgical techniques for OSIA-bone conduction implant placement are needed to enhance comfort, sound localization, and cosmetic outcomes, especially for patients transitioning from Bone-Anchored Hearing Systems (BAHA).

Methods:

A case study at a tertiary center used a novel "upside-down" OSIA 300 implantation with a "lazy-S" incision. The actuator and coil were repositioned closer to the ear canal to improve performance, while the incision reduced skin tension and enhanced cosmesis. Outcomes assessed included surgical complications, patient comfort, and sound localization.

Results:

The modified technique achieved implantation without intraoperative or postoperative complications. Patients reported greater comfort, improved sound localization, and favorable cosmetic results.

Conclusions:

The "upside-down" OSIA 300 approach with a "lazy-S" incision simplifies surgery and enhances comfort, localization, and cosmetic outcomes, offering benefits for patients converting from BAHA systems.

Screw: Problem Solving

Screw: Problem Solving

In mechanical engineering, the interaction between a threaded screw shaft and a plate gear involves analyzing the resisting torque on the plate gear that can be overpowered when a specific torsional moment is applied to the shaft. To better comprehend this concept, consider a generic situation with a threaded screw shaft with a given mean radius and lead and a plate gear with a specified mean radius. The coefficient of static friction between the screw and gear is also provided.
To evaluate the...

Moments of Inertia for an Area about Inclined Axes

Moments of Inertia for an Area about Inclined Axes

In physics and engineering, understanding the moments of inertia for a given area with asymmetrical mass distribution is critical for proper design and analysis. When considering an arbitrary coordinate system, the moments of inertia can be obtained by integrating the moment of inertia for an infinitesimal area element.

Extraction: Advanced Methods

Extraction: Advanced Methods

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Design Example: Traverse Angle Computations

Design Example: Traverse Angle Computations

Traverse angle computations are a critical component of surveying, used to compute the internal angles within a closed traverse. A traverse consists of a series of connected lines forming a closed loop, often used for land boundary delineation or mapping. Calculating the internal angles ensures accuracy in the traverse geometry and is essential for checking survey data integrity.The process begins with known azimuths and bearings of the traverse sides. Internal angles at each vertex are...

Horizontal Curve: Problem Solving

Horizontal Curve: Problem Solving

A horizontal curve is characterized by its radius, intersection angle, and stationing of key points. In this case, the radius is 400 meters, and the angle of intersection is 30 degrees, with the station of the point of curvature (P.C.) at 0 + 150 meters. The goal is to determine the station values at the point of intersection (P.I.), point of tangency (P.T.), and midpoint of the curve, as well as the length of the long chord.The process begins with calculating the tangent distance (T) and the...

Inclination of a Line

Inclination of a Line

The inclination of a line describes its angle of tilt with respect to the horizontal axis. While a line itself is an abstract object with no thickness, its orientation on the Cartesian plane is determined by its slope, which reflects how steeply it rises or falls. The inclination angle, always measured counterclockwise from the positive x-axis, varies between zero and π radians for nonhorizontal lines. This angle directly relates to the slope, providing a geometric interpretation of the...
