This video and protocol demonstrate how to implant a glass-covered cranial window in rodents. These preparations can be used for chronic in vivo two-photon imaging of the neocortex over time scales of months. It may also be used for other types of imaging, including optical intrinsic signal imaging.

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN 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,...

Rodent Stereotaxic Surgery

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...

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.
FAQs
Two-dimensional radiographs provide projected views useful for evaluating jaw relationships, while computed tomography and cone-beam computed tomography display anatomy in three dimensions. The three-dimensional perspective can show skeletal form, asymmetry, airway-related structures, and the location of vital anatomical landmarks more comprehensively. Using these complementary views helps clinicians analyze facial and dental relationships before corrective jaw surgery.
Interpretation focuses on malocclusion, skeletal asymmetry, dental and skeletal relationships, airway-related structures, and nearby vital anatomical landmarks. These findings connect the patient’s functional or facial concerns with the anatomy that may be repositioned during surgery. Identifying their location supports safer planning and helps clinicians anticipate how jaw movement could affect facial relationships and surgical access.
Cephalometric analysis provides a structured way to assess facial and jaw relationships within the digital imaging record. Virtual surgical planning then uses that analyzed anatomy to model corrective jaw repositioning before the operation. Together, these tools translate diagnostic findings into a planned surgical arrangement and can support clearer communication among clinicians involved in treatment.
Digital imaging data can support virtual surgical planning, which establishes the intended repositioning of the jaws. From that plan, clinicians can design patient-specific guides or splints matched to the individual anatomy and planned correction. These devices help transfer the preoperative plan to the surgical setting, supporting more predictable jaw repositioning than relying only on generalized planning information.
The workflow begins with diagnostic image acquisition using two-dimensional radiographs, computed tomography, or cone-beam computed tomography, depending on the information required. Clinicians then review dental, skeletal, soft-tissue, airway-related, and landmark anatomy, perform cephalometric analysis when appropriate, and use the findings for virtual planning. The resulting plan may guide splint or guide design.
Shared digital images and virtual plans give clinicians a common representation of the patient’s anatomy and intended jaw movements, improving communication during treatment planning. The same imaging-based framework also supports evaluation after surgery by allowing clinicians to assess the resulting jaw and facial relationships. In medicine and oral and maxillofacial surgery, this comparison helps judge treatment outcomes.
