Information on treatment and surgery

Re-operative orthognathic surgery

It is essential for re-operative orthognathic surgery to be performed by a surgeon with abundant experience and the knowledge to choose the most appropriate surgical method. This is to minimize any chance of side effects and an unnatural and/or dysfunctional result.
Orthognathic surgery is a highly delicate and difficult procedure that cuts facial bones for adjustment. It is therefore crucial that sufficient planning and surgical procedure is completed by an experienced surgeon, preventing imperfect surgery which leads to unsatisfactory results. In the case of unsatisfactory results, the patient may be required to undergo surgery again but this would be more difficult than the first. Re-operative orthognathic surgery is a complex and even more difficult procedure than the first surgery. It involves proficiency, with no room for error as the surgeon is required to operate on severely damaged anatomical structures and soft tissues. The bone fastening method is the most important aspect towards the end of the surgery and cannot be perfectly achieved without sufficient experience in re-operative procedures. At Zeah Dental Hospital, 3D CT image is used to thoroughly diagnose the problems of the previous surgery. Oral and maxillofacial specialists, cosmetic surgeons and anesthetists collaborate to formulate the most appropriate surgical method and to ensure that the procedure is safe and successful, there are safe surgery and pain management protocols in place.

    Dr. Young Ho Kang (Chairman)

Not all hospitals that can perform orthognathic surgery can provide re-operative orthognathic surgery.

All re-operative orthognathic surgery requires proficient surgical and anatomical knowledge as it is more challenging and complex. This re-operative procedure aims to minimise further damage on surrounding tissues to ensure satisfactory results aesthetically and functionally and eliminating the possibility of another operation or relapse.
