Lymphatic Malformations

Abstract

Lymphatic malformations, classified as one of vascular malformations, are not neoplastic lesions. A particular care must be paid to minimize damage to the surrounding structures and functions. Preoperative diagnostic imaging should be used to determine whether total resection of the mass is feasible. Multiple surgeries may be frequently required to achieve complete resection of the lesion. Cautions must be taken for preserving the nerves and blood vessels especially when displaced by the huge mass. Try best to excise the mass completely; however, sacrifice of important neurovascular structures must be avoided. Partial excision would be suggested; if the dissection proves difficult involving the vital structures, unroofing should be performed by partially excising the walls of the mass to open up the remaining larger lymphatic vesicles. A closed suction drainage would be necessary even if complete excision of the mass appeared grossly evident.
