The complex procedure was carried out by leading consultant Mr Alan Parbhoo and his team to correct problems experienced by a young patient with a severe ‘dentofacial disproportion’ – a form of developmental growth disturbance which caused a significant facial deformity.
The deformity was clearly noticeable and the patient had difficulty eating as well as feeling insecure about his appearance, leading to the decision to seek expert assistance.
Typically, patients with conditions similar to these are treated with orthodontics (braces) and surgery.
Due to the complexity of the surgery, Mr Parbhoo took the decision to use computer aided surgical planning to successfully carry out the five and a half hour procedure.

Working closely with US based companies 3D Systems Inc and Stryker, the process to move the patient’s top jaw forward by 15mm while realigning the top teeth and transplanting bone from the hip, then moving the bottom jaw back, was practiced and demonstrated to the patient in virtual reality prior to surgery.
Mr Alan Parbhoo said: “This pioneering procedure was a major first and an outstanding achievement for all of those involved.
“The severity of this case led me to take the decision to involve US based companies 3D Systems and Stryker which specialise in virtual surgical planning. The ability to plan in advance and practice the procedure using virtual reality beforehand made the outcome highly predictable.
“Since the surgery, I have seen the patient several times. I am extremely pleased to see him making an excellent recovery. He is delighted with the results of the surgery.”
