Blunt dissection
Blunt dissection describes the careful separation of tissues by fingers or convenient blunt instruments during many diverse surgical procedures. Blunt dissection has not changed significantly in centuries and requires great skill, can be tedious, nerve-wracking, and risky. Repairs are often required. Blunt dissection is contrasted to sharp dissection, the practice of slicing through tissues with scalpels, scissors, electrosurgery, or other advanced technologies usually employing heat. New devices are expected to soon make blunt dissection safer, faster and easier.
==Use in pneumothorax==
It is one method employed prior to the insertion of a chest drain following a pneumothorax. Following incision above the rib (to avoid the neurovascular bundle), blunt dissection of the subcutaneous tissue, external, internal and innermost intercostal muscles allows access to the pleura.〔(BTS guidelines for the insertion of a chest drain )〕 Indeed, blunt dissection is now considered the favoured approach for the insertion of large bore chest tubes since it results in fewer complications.〔Haggie JA. Management of pneumothorax: chest drain trocar is unsafe and unnecessary. BMJ1993;307:443. IV〕
