Summary
Partial arytenoidectomy in standing horses effectively treated recurrent laryngeal neuropathy (RLN). This standing surgery offers an alternative to general anesthesia, with most horses returning to athletic use.
Area of Science:
- Veterinary Surgery
- Equine Internal Medicine
- Respiratory Diseases in Horses
Background:
- Recurrent laryngeal neuropathy (RLN) is a common cause of upper airway obstruction in horses.
- Surgical intervention is often required to improve airflow.
- Traditional surgical methods typically require general anesthesia.
Purpose of the Study:
- To evaluate the efficacy and outcomes of partial arytenoidectomy performed on standing, sedated horses.
- To assess the safety and feasibility of this standing surgical approach for RLN treatment.
Main Methods:
- A retrospective study of 14 adult horses diagnosed with unilateral or bilateral RLN.
- Horses underwent unilateral partial arytenoidectomy while standing under sedation and local anesthesia.
- Data collected included signalment, endoscopic findings, prior treatments, and surgical outcomes.
Main Results:
- The procedure was successfully completed in all 14 horses without general anesthesia.
- Nine horses returned to athletic use with improved respiratory noise; two returned with reduced noise.
- Complications included granulomas in three horses, necessitating tracheostomy in two.
Conclusions:
- Partial arytenoidectomy in standing, sedated horses is a viable surgical option for RLN.
- This technique can be considered an alternative to general anesthesia, potentially reducing surgical risks.

Sometimes waves do not seem to move; rather, they just vibrate in place. Unmoving waves can be seen on the surface of a glass of milk kept in a refrigerator, which is one example of standing waves. Vibrations from the refrigerator motor create waves on the milk that oscillate up and down but do not seem to move across the surface. These waves are formed or created by the superposition of two or more identical moving waves in opposite directions. The waves move through each other, with their...

Electromagnetic waves can be reflected; the surface of a conductor or a dielectric can act as a reflector. As electric and magnetic fields obey the superposition principle, so do electromagnetic waves. The superposition of an incident wave and a reflected electromagnetic wave produces a standing wave analogous to the standing waves created on a stretched string.

1.5K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

The starting point for expressing the modes of standing waves is understanding the boundary conditions that the waves must follow. The boundary conditions are derived from the physical understanding of how the standing waves are sustained, that is, how the vibrating particles of the medium behave at the boundaries imposed on them.
For a tube open at one end and closed at the other filled with air, the modes are such that there is always an antinode at the open end and a node at the closed end....

A close look at earthquakes provides evidence for the conditions appropriate for resonance, standing waves, and constructive and destructive interference. A building may vibrate for several seconds with a driving frequency matching the building's natural frequency of vibration; this produces a resonance that results in one building collapsing while the neighboring buildings do not. Often, buildings of a certain height are devastated, while other taller buildings remain intact. This...

Unless individual gases chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each gas in a mixture exerts the same pressure that it would exert if it were present alone in the container. The pressure exerted by each individual gas in a mixture is called its partial pressure.
