The Effects of Le Fort I Osteotomy on Velopharyngeal Function in Cleft Patients

Maxillary retrusion is a common problem in patients with a cleft lip and palate (Semb and Shaw, 1996). The Le Fort I osteotomy is commonly used for the correction of maxillary deformities in cleft and noncleft patients. The need for a Le Fort I osteotomy varies according to the cleft type. In recent literature, the lowest frequency found for a Le Fort I osteotomy was 13% and was performed for an isolated cleft palate (CP) (Antonarakis et al., 2015), whereas patients with a unilateral cleft lip and palate (UCLP) or a bilateral cleft lip and palate (BCLP) exhibited higher frequencies of 40% to 76.5% (Daskalogiannakis and Mehta, 2009; Heliövaara and Rautio, 2011; Heliövaara et al., 2013).
