Blunt dissection
Blunt Dissection
Blunt dissection is a surgical technique where the tissues are separated along natural lines of cleavage by means of a blunt instrument or finger. This method is often used to reduce the risk of injury to delicate structures and to control bleeding.
Pronunciation
The term is pronounced as /blʌnt dɪˈsɛkʃən/.
Etymology
The term "blunt dissection" is derived from the English words "blunt" meaning "not sharp" and "dissection" which comes from the Latin "dissecare" meaning "to cut apart".
Procedure
Blunt dissection is performed by inserting a blunt instrument or finger into the tissue plane and applying lateral pressure to separate the tissues. This technique is often used in surgeries involving the gastrointestinal tract, respiratory system, and cardiovascular system.

Advantages and Disadvantages
Blunt dissection has the advantage of being less likely to cause injury to delicate structures such as blood vessels and nerves. However, it may be more time-consuming than sharp dissection and may not be suitable for all types of surgery.
