Bilateral Reverse Yu Flap for Upper Lip Reconstruction After Oncologic Resection

“…For larger resections, a more-sophisticated reconstruction technique is required to avoid significant distortion of the lip. 5,6 A unilateral crescentic perialar advancement flap is suitable for resections of up to one-third of the upper lip, whereas a bilateral procedure is needed in moreextensive reconstructions. 4,5 This flap can also be used in lateral defects that include the commissure in a single-stage procedure and is then known as Abb e-Estlander.…”

“…5,6 A unilateral crescentic perialar advancement flap is suitable for resections of up to one-third of the upper lip, whereas a bilateral procedure is needed in moreextensive reconstructions. 1,4,6 All of these flaps produce some level of microstomia. This is an advancement-rotational flap that allows labial continuity in a single surgical procedure and preserves sensitivity and motor function.…”

“…5 A Karapandzic reverse flap can be used for defects involving more than one-third of the lip. [4][5][6][7][8] In 1989, Yu described a new flap for lower lip reconstruction after oncologil resections. 4,5,7,8 The reverse Gillies flap is a single-stage rotationaladvancement flap also used for large upper lip defects.…”

“…It can produce denervation, which is usually temporary. 1,4,6 All of these flaps produce some level of microstomia. Crescentic perialar advancement, reverse Karapandzic, and reverse Gillies flaps produce rounded commissures, so these techniques have the disadvantage that a second-stage commissuroplasty is almost always necessary to ensure mouth opening.…”
