tangential excision
Pronunciation: tan-JEN-shal
Surgical technique removing thin layers of burned tissue sequentially until viable tissue is reached.
Full Definition
Tangential excision is a surgical technique that involves the sequential removal of thin layers of burned tissue using a dermatome or knife until viable, bleeding tissue is encountered. This approach preserves maximal amounts of viable tissue while ensuring complete removal of necrotic material. The technique is particularly useful for deep partial-thickness burns where the depth of injury is uncertain. Tangential excision typically results in better functional and cosmetic outcomes compared to fascial excision but requires more surgical expertise.
Usage
Usage note: Describes surgical approach, not depth of injury; contrast with fascial excision.
