METHOD FOR TREATING CANCER OF THE LOWER LIP Russian patent published in 2006 - IPC A61B17/24 

FIELD: medicine, oncology.

SUBSTANCE: one should cut a skin-muscular flap from buccal external side being 1.0 cm larger against the half of defect's length, moreover, at the side with intact mouth angle one should form a stump of red border of the lower lip due to through incision. For covering internal defect's side one should cut horizontal rectangular mucous-muscular flaps from buccal internal side with foundation facing the mouth of excretory duct of parotid salivary gland. Flaps should be mobilized at the level of surface muscular fibers of buccal muscle being adjacent to mucous membrane. Then it is necessary to dissect a triangular skin-fatty flap in mental area at foundation being equal to defect's length and the top being about 1.5-2.0 cm below mandibular edge. Defect's covering should be started from coinciding mucous-muscular flaps and then - skin- muscular ones. Then red border of lips should be formed. For this purpose, one should fulfill a through incision in intact mouth angle's area towards the upper lip by leaving 0.5 cm against the edge of red border. Prepared parts of the red border of lips should be replaced with their tops towards each other to be sutured together and layer-by-layer sutured up to replaced flaps. The innovation enables to increase flaps' mobility, develop the stump of red border of lips, create anatomical integrity of the lower lip, form angles of the mouth, prevent deformation in area of donor's channel and decrease post-operational complications.

EFFECT: improved cosmetic effect of operation.
