Comprehensive Cleft Care in a Nine-Year-Old With Unilateral Cleft Lip and Palate Using Coffin Spring Expansion and Surgical Intervention.

Cleft lip and palate (CLP) represent a common congenital defect, which needs a multidisciplinary team approach for satisfactory aesthetic and functional correction. Transverse discrepancies are among the major problems in CLP cases, and maxillary expansion has been used to correct skeletal and dental transverse discrepancies between the mandible and maxilla. During the long period, many types of expansion protocols have been cited in the literature. This report presents the treatment of a nine-year-old patient with unilateral CLP and emphasizes the combination of orthodontic and surgical interventions. The maxillary expansion was achieved by Coffin spring, and then oronasal fistula closure surgery was done for both function and aesthetic purposes.
