Perialar semilunar advancement flap for the reconstruction of nasal sidewall defects: Our experience

Generally accepted approaches to reconstruction of nasal sidewall include advancement flaps from adjacent reservoirs, namely, cheek advancement flap, nasal dorsum advancement flap, nasal island pedicle flap, and perialar crescentic advancement flap, as well as more laborious and two-stage regional flaps such as glabellar or frontal transposition flaps or even skin grafts, with the latter compromising the aesthetic result given the mismatch in skin texture and color. [...]the defect is closed exaggerating the depth on the alar side in order to recreate the alar-facial groove [Figure 2]. The risk of compromising the valve function of the nose is theoretically low since there is no interference with the nasal tip or ala, but it could potentially result from disturbing the position or angulation of the free alar margin, which could be overcome by placing the tension of the suture of the alar groove in a horizontal plane.
