#MondaYmaging: seminari d'imatge mèdica | Assessment of physiological bone resorption of secondary alveolar bone graft by low-dose CT in patients with unilateral cleft lip and palate
Speakers:
Marta Gómez Chiari and Martí Engli Rueda, IRSJD investigators
Summary
Cleft lip and palate is the most frequent congenital craniofacial malformation (1:700 RN), and it is accompanied by other congenital deformities such as dental anomalies, facial hypoplasias and functional alterations, making its treatment complex and multitemporal. A fundamental part of the treatment is the alveolar graft for the reconstruction of the maxillary defect, providing continuity in the arch and supporting the nose.
Thanks to the introduction of 3D planning, operating room time has been substantially reduced, and has allowed us to optimize the calculation of the amount of bone from the iliac crest to be extracted, allowing less invasive surgeries and faster postoperative evolution. . The post-surgical evaluation at 4-6 months tells us about the success of osseointegration, as well as the physiological loss of the graft.
We are currently working on a project on the calculation of the physiological loss of the secondary alveolar graft, analyzing the tendency of bone resorption of the graft under normal conditions, to calculate the percentage of expected physiological loss, as well as its directional gradient; these factors probably influence the time of pre-surgical planning, and which are currently not assessed using 3D methods, to determine the type of graft, location and percentage of overcorrection necessary.
