The Guide for the Care and Use of Laboratory Animals1 dictates that rodent survival surgery be performed aseptically. Aseptic technique utilizes specific practices that minimize the contamination of the surgical site, including patient preparation, surgeon preparation, sterilization of instruments and other supplies, and the use of a clean and controlled environment. Presurgical planning,...

The present protocol describes a step-by-step guide for the complete endoscopic removal of epitympanic cholesteatoma with different techniques for cholesteatoma dissection and bone removal for...

Redo foregut surgery is associated with increased patient morbidity and presents a technical challenge for the surgeon. We describe our approach and considerations when performing a redo hiatal hernia repair to provide a guide for other surgeons and improve patient...

Before attempting surgery, a new surgeon should have training in basic surgical techniques and concepts. This article will present basic surgical considerations with an emphasis on...

The monitoring of extracellular neurotransmitter levels in distinct brain regions of freely moving animals offers insights on the link between neurotransmitter release and behavior. In vivo microdialysis coupled with electrochemical detection provides excellent anatomical and chemical resolution; and information on how basal neurotransmission is altered by pharmacological or physiological manipulations.

Stereotaxic (or stereotactic) surgery is a method used to manipulate the brain of living animals. This technique allows researchers to accurately target deep structures within the brain through the use of a stereotaxic atlas, which provides the 3D coordinates of each area with respect to anatomical landmarks on the skull. After the skull is exposed, anesthetized animals are mounted on a specialized instrument known as a stereotaxic frame, which enables the precise placement of experimental...
