코성형 (ko-seonghyeong) is the everyday Korean word for rhinoplasty — literally “nose shaping.” The term covers both functional and aesthetic nasal surgery, from bridge augmentation to tip refinement to septoplasty.
In clinical practice, Korean surgeons distinguish between augmentation rhinoplasty (building up the bridge, most common among East Asian patients) and reduction rhinoplasty (narrowing or refining a larger nose, more common in Western patients). The specialization in augmentation is one reason international patients seek Korean surgeons specifically.
