Background: The accurate knowledge of the three–dimensional
properties of the missing bone is necessary for the
reconstruction of bony craniofacial deformities as a result of
cancer procedures.
Aim: The objective of this study is to evaluate the accuracy
of post-operative three-dimensional computerized tomography
by overlapping it with previous planned one.
Patients and Methods: The study was conducted on 20
patients presented to The Plastic Surgery Department at Sohag
University Hospital, and at Maxillofacial Department Nasser
Institute and private clinic (IDC) between May 2021 and May
2022. Virtual planning programs were used for preoperative
assessment and planning as: Memics Medical 21, 3-matic
medical 13 and proplan program.
Result: Regarding our finding, we included two categories,
1st category was craniofacial implant (12) 60% and 2nd
category was 8 (40%) orthognathic surgeries. In implant
category, 9 cases had accuracy ranged from 97 to 98.8% and
3 cases had accuracy ranged from 83.5-86%. In orthognathic
category, 8 cases had accuracy ranged from 97.8 to 99% and
2 cases had accuracy ranged from 75.6 to 76.9%.
Conclusion: This prospective cohort study shows that
virtual surgical planning significantly yielded satisfactory
outcomes, alongside negligible three-dimensional deviation
postoperatively in patients who needed craniofacial surgeries.
This indicates CAD/CAM allows for faster surgery, greater
aesthetics, and may be accomplished for the same price as
traditional techniques.
