Presurgical Infant Orthopedics Appliance in Complex Craniofacial Deformity Involving Complete Cleft Lip and Palate Patients: A Case Series

Tessier facial clefts are rare congenital abnormalities and among the most challenging deformities treated by craniofacial surgeons. Despite various surgical interventions, treatment outcomes remain limited, resulting in a higher burden of care and lower quality of life. PreSurgical Infant Orthopedics (PSIO) has shown benefits in cleft care, but its application to Tessier clefts is underreported. This report assesses the long-term surgical outcomes of 3 patients with Tessier clefts who underwent PSIO. The cleft width and premaxilla reduction were observed in all 3 patients.
