Mohs micrographic excision
Pronunciation: MOZE my-kroh-GRAF-ik ex-SIZH-un
A specialized surgical technique used in burn reconstruction where tissue layers are excised and examined microscopically in real-time to achieve precise margins while preserving healthy tissue.
Full Definition
Mohs micrographic excision, when applied to burn surgery, represents an adaptation of the dermatologic technique for precise tissue removal during burn reconstruction procedures. This method involves systematic layer-by-layer excision of scar tissue with immediate frozen section examination to ensure complete removal of abnormal tissue while maximizing preservation of healthy surrounding structures. The technique is particularly valuable in complex burn reconstruction around critical anatomical areas such as the eyelids, nose, and hands where tissue conservation is paramount. Unlike traditional burn excision methods, Mohs technique allows real-time histologic verification of clear margins, reducing the need for subsequent revision surgeries. The procedure requires specialized training and close collaboration between the burn surgeon and dermatopathologist.
Usage
Usage note: Named after Dr. Frederic Mohs. Capitalize 'Mohs' as it's a proper noun. Distinguish from standard Mohs surgery used for skin cancer.
