tangential excision

Full Definition

A surgical debridement technique that involves the sequential removal of thin layers of burned tissue using specialized instruments such as the Weck knife or dermatome until healthy, bleeding tissue is encountered. This method preserves maximum viable tissue while ensuring complete removal of necrotic material, making it particularly useful for partial-thickness burns where some dermal elements may be salvageable.

Usage

Usage note: Distinguish from fascial excision, which removes tissue down to the fascial layer.
