Maxillary Expansion Using Transpalatal Distraction in Patients with Unilateral Cleft Lip and Palate

Abstract

Surgically assisted rapid palatal distraction osteogenesis using a transpalatal distractor results in a high rate of success in correcting maxillary transverse width discrepancies and dental crossbite and offers a harmonious maxillary arch shape in patients with unilateral cleft lip and palate.

A systematic review of the effects of bone-borne surgical assisted rapid maxillary expansion

“…Thirteen publications fulfilled all inclusion criteria (Matteini and Mommaerts, 2001;Pinto et al, 2001;Neyt et al, 2002;Gerlach and Zahl, 2003;Ramieri et al, 2005;Koudstaal et al, 2006a,b;Hansen et al, 2007;Scolozzi et al, 2007;Seitz et al, 2007Seitz et al, , 2008Tausche et al, 2007Tausche et al, , 2008.…”

“…The procedure for retaining the achieved expansion after removal of the distractor was not reported in nine studies (Matteini and Mommaerts, 2001;Pinto et al, 2001;Neyt et al, 2002;Gerlach and Zahl, 2003;Ramieri et al, 2005;Koudstaal et al, 2006a,b;Scolozzi et al, 2007;Seitz et al, 2008).…”

“…Report of treatment related difficulties i.e., appliance failure, surgical complications (Neyt et al, 2002;Gerlach and Zahl, 2003;Ramieri et al, 2005;Koudstaal et al, 2006a,b;Scolozzi et al, 2007;Seitz et al, 2008). Dental and periodontal side effects (Ramieri et al, 2005).…”

“…Modifications of the Glassman approach were vertical corticotomy of the piriform aperture (Gerlach and Zahl, 2003;Tausche et al, 2007), midpalatal dysjunction (Pinto et al, 2001;Ramieri et al, 2005;Koudstaal et al, 2006a,b;Seitz et al 2008), pterygoid and midpalatal dysjunction (Matteini and Mommaerts, 2001;Gerlach and Zahl, 2003), or a unilateral approach in cleft lip and palate patients (Ramieri et al, 2005;Koudstaal et al, 2006b;Scolozzi et al, 2007).…”

“…In the anterioreposterior direction the distractors were either placed at the level of the maxillary second premolar (Pinto et al, 2001;Gerlach and Zahl, 2003;Ramieri et al, 2005;Scolozzi et al, 2007;Tausche et al, 2007;Seitz et al, 2008) or at the level of the fist molar (Matteini and Mommaerts, 2001;Gerlach and Zahl, 2003;Ramieri et al, 2005).…”
