345 Plastic Surgery
Verified116, Bongeunsa-ro, Gangnam-gu, Seoul (Eunseong Building 3F, 7F)
Overview
1 / 10
345 Plastic Surgery (삼사오성형외과) is a Gangnam plastic surgery clinic near Sinnonhyeon Station specializing in facial contouring and aesthetic surgery. Its name reflects the three fundamental facial shapes the clinic builds from — triangle, square and circle.
The clinic is led by two chief surgeons who deliberately pair "bone" (skeletal) and "soft tissue" (muscle, fat, skin) expertise: Dr. Park Jong-lim, a facial-bone specialist with 10,000+ surgeries and ~26 years of experience, and Dr. Han Gyu-nam, a soft-tissue and lifting specialist with ~19 years. Together the team reports 15,936+ combined surgeries (as of 2026).
Services span facial contouring, two-jaw surgery, lifting and anti-aging, rhinoplasty, eyelid surgery, breast surgery and body contouring, with an in-house dermatology clinic for medical recovery. Operating rooms are documented via CCTV with on-site board-certified anesthesiologists, and the clinic emphasizes natural results that age gracefully over time.
Our Core Values
Bone + Soft-Tissue Together
345\'s defining approach pairs a facial-bone specialist with a soft-tissue specialist, so contour is created from both the skeleton and the overlying muscle, fat and skin — producing natural results without excessive bone reduction.
Built on Three Shapes
The clinic\'s philosophy holds that every face is built on triangle, square and circle. Surgery is planned around these fundamentals to create balance that ages gracefully over time.
Experience & Volume
With 15,936+ combined surgeries and chief surgeons of ~26 and ~19 years, complex contouring and revision cases are handled with depth of experience.
Safety Systems
CCTV-documented operating rooms, on-site board-certified anesthesiologists and advanced diagnostic imaging support a safety-first surgical environment, backed by long-term follow-up care.
