USING MODEL 3D TO PLANNING OF CRANIOPLASTY IN CHILDREN WITH CRANIOSYNOSTOSIS

Introdução

Craniosynostosis or premature closure of cranial sutures is a early fusion of one or more cranial sutures, leading to cranium’s inappropriate growth, which can to lead to increased intracranial pression and further neurologic, cognitives and visual disfunctions. Corrective surgery is complex because of anatomy’s details of each patient’s brain, so, neurosurgeons look methods safer to planne surgery. The model 3D perhaps be underlying piece to search these aspects.

Objetivo

To show advantages and disadvantages of use of model 3D in surgery of cranioplasty in children with craniosynostosis.

Método

The research was carried out from 2022 to 2023, and 17 children underwent cranioplasty to correction of craniosynostosis, which, four were carrier of complex craniosynostosis, two carrier of some syndrome and two with no syndrome. The preoperative period was carried out with the aid of three-dimensional molds, made of different low-cost materials, printed from digital models of computed tomography scans of the skull with three-dimensional reconstruction. The molds were used for individual anatomic study of each patient, to carry out planning of surgery and to make markings for surgical planning, which were used as a basis for markings on the patient.

Resultados

The time average of surgery was nearly 266 minutes in single craniostenosis and 440 minutes in complex craniostenosis. Surgery time is very important because costs, risk of infection at the surgery site, and present anesthetic time with direct relationship with length of procediment. In spite of use of models in overall types of craniosynostosis, there was most expressive decreasing of length in cranioplasties of complex craniosynostosis. The fact that soft parts are not represented in the models has great advantage of visualizing bony anatomical frame, however, it ruled out the possibility of anatomical study of soft parts. The models used by our team are considerably less expensive than more complex models, so there isn`t an excessive impact on the cost of the procedure, nevertheless, they have the disadvantage because don`t reproduce the physical characteristics of human bone or allow their use to simulate the procedure on the part, being used only for making markings and visual studies.

Conclusão

Use of model 3D was most useful to conduction of cranioplasty surgery, mainly in children with complex craniostenosis.
