Introducción: Analizar y describir las características óseas en pacientes con defectos óseos cráneo-faciales complejos, utilizando un software de reconstrucción tridimensional. Determinar la utilidad y aplicabilidad en el planeamiento y tratamiento quirúrgico de los pacientes. Métodos: Se realizó muestreo poblacional de pacientes con defectos óseos cráneo-faciales complejos tomando datos de historia clínica y tomografías computarizadas, determinando las características físicas y densitométricas de los huesos y realizando el análisis diagnóstico y planeación de tratamiento. Se realizó recolección de datos y posterior análisis usando el software Stata 12.0, cuantitativo y cualitativo, demostrando significancia estadística con prueba de chi2. Resultados: Se recolectó información de 50 pacientes de los cuales el 70% correspondían a hombres, la edad promedio fue de 37 años, la causa más frecuente fue traumática secundaria a accidente de tránsito, el hueso comprometido en la mayoría de los pacientes fue la mandíbula y el tamaño del defecto llego a ser hasta de 234 mm. El análisis de los pacientes con software de reconstrucción tridimensional permitió crear un algoritmo de enfoque diagnóstico y tratamiento. Se muestran algunos casos. Conclusiones: La utilidad de la implementación de tecnología CAD/CAM en el manejo de reconstrucciones óseas cráneo-faciales está demostrada, representan un alto costo para el paciente y el sistema de salud. Es posible mediante la implementación de software gratuitos y el trabajo multidisciplinario con servicios como biomedicina, diseño industrial e ingenierías, aplicar esta tecnología en pacientes, aprovechando sus beneficios en la reconstrucción de defectos complejos así como disminuyendo sus costos
Introduction: Multiple technologies help the development of reconstructive surgical procedures in craniofacial surgery, Surgeon's perception of this type of diagnostic and treatment aids has not been widely studied. Methods and Materials: A workflow is proposed for the management of craniofacial bone defects, then the results are showed to the staff in charge for the treatment of these patients. A survey was subsequently applied, evaluating the degree of satisfaction and perception the perception of the staff regarding applicability, usefulness, impact on different process factors of treatment. Descriptive analysis was performed. Results: 30 people were interviewed: specialists, residents of surgical specialties, general practitioners, medical students. The majority did not have experience with CAD / CAM technology (77%), but considered useful (67%), the considered disadvantages were: technical difficulty, administrative procedures to access, costs, lack of information, need for specific training. The benefits were: Improvement in diagnosis and treatment accuracy, specificity, help in planning, innovation, and versatility. Discussion: Tools such as 3D printing, CAD / CAM technology, facilitate the process of anatomical understanding, planning of the surgical procedure and execution of surgery, implementing the Survey in our service we could show that the perception of the majority of the participants agrees with these data, where the impact and utility of the application of this technology in the treatment of patients is evident, both for graduate surgeons and those in training. Conclusions: The application of technologies in the practice of medicine is useful, facilitates the technical execution of the procedure precision, reduces surgical time and costs. Information and studies that evaluate the surgeon's perception regarding the applicability of CAD / CAM technology in the treatment of craniofacial bone defects are not enough, which represents a novelty of our study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
