Orthognathic Surgery Consultations

Your initial Jaw Surgery Consultation

You will need a referral and have available x-rays (lateral ceph, OPG are minimum requirements) and if possible a current set of stone/plaster models of your teeth. At this appointment, you will meet Dr Lydia Lim and her staff. Dr Lim will take a full history and assess your face and bite. A preliminary treatment plan is recommended and Dr Lim will explain the details of surgery often using a powerpoint presentation on screen with images of surgical techniques and Dr Lim will also be able to illustrate the outcomes showing relevant clinical photographs of past patients. Photos are taken and x-rays scanned in for the possibility of computerized imaging and planning if appropriate to the patient. Often it may be possible to view a facial prediction before/after surgery for the individual patient using specialised computer software. Dr Lim will discuss the risks of surgery and answer any questions patients may have. Information brochures are issued as well as a detailed fee schedule. A report will be generated and sent to the orthodontist. Orthognathic surgery is a team approach and at the initial consultation a preliminary treatment plan is formulated but needs confirmation with the orthodontist. Often, further discussion between Dr Lim and the orthodontist is required to discuss the specifics of a case and may take place by phone, email or a face-to-face meeting. Once the plan is agreed upon , the patient starts the process of pre-surgical orthodontics which usually lasts approximately 12 months.


Surgical Work-up Appointment

This appointment is necessary for all jaw osteotomy patients. Dr Lim will perform detailed facial measurements, take facial and bite records, assess the stone models of the teeth, perform computerized x-ray analysis and planning, decide on the precise jaw movements required.


At this appointment, there is opportunity to ask questions and information will be given on how to prepare for surgery, what to expect, hospital details, and the recovery process including diet instructions, management of post-operative elastics, and a kit will be issued. Complications are again discussed and consent forms are signed. Blood tests are arranged.  It may be helpful to bring a support person who may assist in the recovery process.


Following the surgical work-up, Dr Lim will use the records she has taken and the surgical plan to proceed with the laboratory simulation and model surgery, to create surgical splints or templates for the operation.
