Training and career
The clinic records internship and residency in oral and maxillofacial surgery at Samsung Medical Center from 2000 to 2004. His biography lists subsequent leadership of oral and maxillofacial surgery at Cheongju St. Mary’s Hospital, work at Wonjin and BK Plastic Surgery, founding Dacapo Oral & Maxillofacial Surgery Dental Clinic, and work at Shanghai Hankyung Hospital. His current profile identifies him as a board-certified oral and maxillofacial surgeon.
Why a chin patient may seek this assessment
Sinsa’s service information includes recessed chin or jaw, chin disproportion and facial asymmetry. Ask Dr. Jung whether the visible concern is isolated to the chin segment or relates to the position of the jaw and bite. If you have chewing difficulty, a history of orthodontics or trouble closing your lips comfortably, explain those issues before discussing a cosmetic design. They may change the evaluation and the range of suitable treatments.
Using imaging to understand the options
The clinic describes 3D-CT planning. Ask the surgeon to show the proposed chin change in relation to the lower jaw, nerve pathways and tooth roots. Clarify whether the operation changes only the outline or also changes the position of the tooth-bearing jaw. If orthodontics is part of the recommendation, discuss where that treatment would happen and how it would be coordinated across countries.
For an isolated chin operation, ask why that limited approach is appropriate. For a larger jaw operation, ask what functional problem it treats and why chin surgery alone would not address it. The scope of surgery should be linked to the diagnosis and your priorities.
Planning care in Changwon
The clinic is in Changwon rather than Seoul. Confirm the appointment address and arrange travel around the required local reviews. Ask who provides anesthesia and after-hours coverage, which records you should obtain before travel, and how postoperative imaging and dental follow-up will be organized. Before returning home, establish how Dr. Jung’s team will communicate with your local dentist or clinician if continuing treatment or an in-person review is needed.
Arrange a consultation with the named specialist
When contacting Sinsa Oral & Maxillofacial Surgery, request Dr. Ji-woong Jung by name and specify whether you want an initial assessment or a second opinion. Ask whether the first discussion will be with the surgeon or a coordinator, and whether the same clinician will explain the final plan after examining you. Bring a short list of changes you would like and features you want to preserve.
