Initial cleft severity and maxillary growth in patients with complete unilateral cleft lip and palate

Preoperative Cleft Lip Measurements and Maxillary Growth in Patients With Unilateral Cleft Lip and Palate

“…The fact that cleft lateral lip height and transverse width were inversely correlated in our sample explains why both of these measurements displayed associations with maxillary length. From the other studies that examined maxillary length in relation to initial cleft severity (Table 5), four were in line with our results (Peltom¨aki et al, 2001;Honda et al, 2002;Liao and Mars, 2005;Liao et al, 2010), while five did not find significant associations (Suzuki et al, 1993;Nakamura et al, 2005;Chiu et al, 2011;Tomita et al, 2012;Wiggman et al, 2013). Maxillary protrusion was also found to be partly dependent on cleft severity as defined by preoperative cleft lip measurements in this study.…”

“…Both cleft lateral lip height and transverse width were found to be correlated with maxillary protrusion. Among the other studies examining cephalometric variables representing maxillary protrusion (Table 5), four found positive associations with initial cleft severity (Peltom¨aki et al, 2001;Liao and Mars, 2005;Liao et al, 2010;Doucet et al, 2014), while Chiu et al (2011) found an association with alveolar but not basal maxillary protrusion. On the other hand, five studies found no such associations (Nakamura et al, 2005;Meazzini et al, 2008Meazzini et al, , 2011Tomita et al, 2012;Wiggman et al, 2013).…”

“…This highlights the importance of establishing a precise initial evaluation of the malformation to avoid comparing different entities and making flawed assumptions (Meazzini et al, in press). Cleft subtypes within a population could be established using clinical criteria, such as cleft lip hypoplasia (Cosman and Crikelair, 1965;Boorer et al, 2011), cleft palate severity (Suzuki et al, 1993;Peltom¨aki et al, 2001;Chiu et al, 2011), or nasolabial deformity (Lindsay and Farkas, 1972;Fisher et al, 2008).…”

“…Several studies have suggested that patients with more severe palatal or alveolar clefts or greater palatal tissue deficiency exhibit less favorable maxillary growth and poorer dental arch relationships (Schwartz et al, 1984;Suzuki et al, 1993;Peltom¨aki et al, 2001;Honda et al, 2002;Liao and Mars, 2005;Liao et al, 2010;Chiu et al, 2011;Chiu and Liao, 2012;Hsieh et al, 2012;Tomita et al, 2012). However, other studies do not support this idea (Johnson et al, 2000;Meazzini et al, 2008Meazzini et al, , 2011Reiser et al, 2010;Wiggman et al, 2013).…”

Presurgical Cleft Lip Anthropometrics and Dental Arch Relationships in Patients with Complete Unilateral Cleft Lip and Palate

“…Liao et al (2010) cephalometrically determined that patients with a large cleft at the time of palate repair have a shorter and more retrusive maxilla by 9 years of age than those with a small cleft. Also using cephalometric radiographic data, Chiu et al (2011) demonstrated that a large cleft at birth increases the tendency for maxillary retrusion. On the other hand, using the GOSLON yardstick on dental study models, Hsieh et al (2012) found that patients with CUCLP who have wide initial clefts are more likely to develop poor dental arch relationships by age 5.…”
