Dr. Yonghae Seong

Dr. Yonghae Seong is the Head Surgeon at GNG Hospital, a comprehensive 13‑floor medical facility in Seoul that integrates plastic surgery and otolaryngology services. With over 17 years of clinical experience, he holds dual board certification in both otolaryngology and plastic surgery, a rare combination that uniquely qualifies him to address both the aesthetic shape and functional performance of the nose. He specialises in functional rhinoplasty and cosmetic nasal reshaping, combining procedures such as septoplasty, turbinate correction, and sleep apnea treatment with aesthetic refinement. His core philosophy is that a beautiful nose must also function perfectly, so every procedure improves breathing, airflow, and nasal health alongside appearance. This integrated approach has made GNG Hospital a leading destination for patients seeking safe, balanced, and long‑lasting results, serving both Korean and international clients.
