dissection

Examples of dissection in the following topics:

• Marfan Syndrome

  • Sometimes, no heart problems are apparent until the weakening of the connective tissue in the ascending aorta causes an aortic aneurysm or aortic dissection; a surgical emergency.
  • An aortic dissection is most often fatal and presents with pain radiating down the back, giving a tearing sensation.
  • If the dilation of the aorta progresses to a significant diameter aneurysm, causes a dissection or a rupture, or leads to failure of the aortic or other valve, then surgery becomes necessary.
  • A micrograph of an aorta with an obvious dissection.

• Defining Anatomy

  • Surface anatomy (or superficial anatomy) is the study of external anatomical features without dissection.
  • This field has moved from examination of animals and cadavers through invasive dissection to the technologically complex techniques developed in the 20th century, such as non-invasive imaging and radiology.
  • Medical and dental students also learn through the dissection and inspection of cadavers.

• Tonsillectomy

  • Removal is typically achieved using a scalpel and blunt dissection or with electrocautery; In some cases, harmonic scalpels or lasers are used.

• Anatomy of the Digestive System

  • Upon gross dissection, the duodenum may appear to be a unified organ, but it is often divided into two parts based upon function, arterial supply, or embryology.

• Anatomical Position

  • Dissection of cadavers was one of the primary ways humans learned about anatomy throughout history, which has tremendously influenced the ways by which anatomical knowledge has developed into the scientific field of today.

• Sacral and Coccygeal Plexuses

  • These two nerves sometimes arise separately from the plexus and, in all cases, their independence can be shown by dissection.

• Mechanisms of Hormone Action

  • As a result, hormonal signaling is elaborate and hard to dissect.

• Organization of Motor Neuron Pathways

  • A deep dissection, lateral view of a brainstem.

• Pericarditis

  • The diagnostic test for cardiac tamponade, is trans-esophageal echocardiography (TEE) although trans-thoracic echocardiography (TTE) can also be utilized in cases where there is a high suspicion of aortic dissection and high blood pressure, or in patients where esophageal probing is not feasible.

• Rhinoplasty

  • Except for the columellar incision, the technical and procedural approaches of open rhinoplasty and of closed rhinoplasty are similar, yet the closed rhinoplasty procedure features reduced dissection (cutting) of the nasal tissues (no columellar incision), decreased potential for the excessive reduction (cutting) of the nasal-tip support, reduced post-operative edema, decreased visible scarring, decreased iatrogenic (inadvertent) damage to the nose by the surgeon, increased availability for effecting in situ procedural and technical changes, palpation that allows the surgeon to feel the interior changes effected to the nose, shorter operating room time and quicker post-surgical recovery and convalescence for the patient.
