Crescentic advancement flap
Crescentic advancement flap
The crescentic advancement flap is a simple, yet powerful, variation of a unilateral advancement flap. Traditionally used along the alar crease and nasofacial sulcus, this technique is frequently employed for modestly sized nasal sidewall defects. This permits the surgeon to effectively hide incision lines in cosmetic subunit boundaries, andโimportantlyโas the curved crescents of tissue lengthen, this approach may obviate the need for dog-ear removal as well (Fig. 21-20).
Figure 21-20. A crescentic advancement flap is designed to close an operative wound adjacent to the nasal ala with the upper and lower limbs of the advancement falling along the nasofacial sulcus, alar crease, and nasolabial fold. The design is simple in appearance but deceptively complex. As the flap advances, the shorter crescentic limbs stretch out to meet their destination and dog ears are not produced. Crescentic modification of a bilateral advancement flap may avoid the need for the removal of standing tissue cones.
