ObjectiveTo develop a preoperative planning method using augmented reality (AR) of a specific surgical procedure: fetoscopy for myelomeningocele repair.MethodsImaging data were acquired of a pregnant woman at 27 weeks of gestation whose fetus was diagnosed with myelomeningocele. The patient was identified as a candidate for fetoscopic repair of the spine defect, and an AR application for mobile device simulation was developed. The virtual customized model was created by analysis of the presurgical magnetic resonance imaging. A real-time AR interface was developed by using an application that enhanced the anatomical aspects of both mother and fetus.ResultsA virtual model for planning fetoscopy repair for myelomeningocele was developed. Preoperative and postoperative procedures were successfully carried out, emphasizing the beneficial role of the AR application. The use of the AR model allowed the multidisciplinary team to engage in discussion to determine the appropriate surgical approach. It also allowed a clearer explanation of the procedure to the parents enabling a better understanding of the parents regarding specifics characteristics of their baby's spine defect.ConclusionsThis new preoperative platform using a virtual model represents an important tool to improve patient's comprehension, multidisciplinary discussion, and surgical planning. In addition, it can be used worldwide as a teaching tool in the fetal surgery field.Copyright © 2021 Elsevier Inc. All rights reserved.
