Full-thickness crescentic advancements
Large wounds of the central or off-center upper lip can be repaired by a modification of the crescentic advancement flap. If the wound is of modest size and is off center, a unilateral crescentic advancement can suffice. The wound is squared off and excised full thickness to the gingival sulcus. The excision is carried around the ala laterally as a partial-thickness excision that preserves neurovascular integrity. The mucosa is incised as well, allowing for sufficient flap mobility. The lower portion of the wound is closed as a wedge with reapproximation of all lamellae; the upper portion is closed as a
crescentic advancement.4,22 If the wound is large and central in location, bilateral rotations may be performed23 with crescents around each nasal ala. Large wounds of the central upper lip can be repaired in this manner, with preservation of neurovascular anatomy and functional restoration of the oral sphincter.
