What to explore at GNG Hospital
GNG combines cosmetic rhinoplasty and ENT care, including septal surgery, contracted-nose reconstruction and revision for nasal obstruction. Dr. Yong-Hae Seong’s background includes Catholic University medical education and Internship and residency at Gangnam St. Mary’s Hospital. Ask which proposed steps address appearance and which address obstruction, with an explanation of why each is needed. For a contracted nose or persistent obstruction after surgery, bring previous operation details and ask how they affect the graft and reconstruction options. A useful question to bring to your appointment is: “Which functional and cosmetic procedures are actually included in my plan?” Also ask: “Who is my operating ENT surgeon and what relevant cases can I review?”

Clinic medical team
Do-Jin Hyun
Sleep Medicine Doctor
Dr. Do-Jin Hyun’s GNG biography focuses on sleep medicine. It records medical and doctoral study at the Catholic University of Korea, internship at St. Mary’s Hospital, residency at Gangnam St. Mary’s, and an associate professorship. A polysomnography technologist credential is also reported. His individual service record includes septal surgery, but the reviewed material does not establish cosmetic rhinoplasty as his principal role. He should therefore be distinguished from surgeons specifically profiled for aesthetic nasal reshaping.
Training, appointments & professional background
- Catholic University medical and doctoral education
- Residency at Gangnam St. Mary’s Hospital
- Sleep-medicine focus and polysomnography credential reported
