“…18 No differences were observed between RME and SME except for the capability of the quad-helix in promoting differential expansion in the anterior and posterior regions, and a shorter treatment time for the RME therapy. 18 Recently, Almeida et al 19 compared the skeletal effects of rapid and slow maxillary expansion in BCLP using pre-expansion and postretention cone-beam computed tomography (CBCT). Haas/Hyrax and Quad-helix type appliances similarly promoted significant increases in all the measured maxillary transverse dimensions at the premolar and molar regions.…”

Objective: To compare the dentoskeletal effects of rapid (RME) and slow (SME) maxillary expansion in patients with bilateral complete cleft lip and palate (BCLP). Materials and Methods: This was a secondary analysis of a previous randomized controlled trial (RCT). Forty-six patients (34 male, 12 female) with BCLP and posterior crossbite (mean age of 9.2 years) were randomly assigned to two study groups. Group RME comprised subjects treated with Haas/Hyrax expander. Group SME included patients treated with quad-helix appliance. Cone-beam computed tomography (CBCT) was performed before expansion (T1) and after appliance removal at the end of a 6-month retention period (T2) for a previous RCT that compared the transverse skeletal effects of RME and SME. CBCT-derived cephalometric images were generated and cephalometric analysis was performed using Dolphin Imaging Software (Chatsworth, Calif). Intergroup comparisons were performed using t tests (P < .05). Results: Baseline forms were similar between groups. No significant differences between RME and SME groups were found. Conclusions: Rapid and slow maxillary expansion produced similar sagittal and vertical changes in patients with BCLP. Both Haas/Hyrax and quad-helix appliances can be used in patients with vertical facial pattern. Clinical relevance: RME and SME can be equally indicated in the treatment of maxillary arch constriction in patients with BCLP.

Purpose:The aim of the current study was to evaluate the skeletal and dentoalveolar effects of rapid palatal expansion (RPE) in children with cleft lip and palate (CLP), ages 8 to 12 years treated with 2 expanders. Methods: Twenty Egyptian children with complete bilateral CLP exhibiting maxillary transverse deficiency were divided randomly into 2 groups according to the appliance used for expansion: (A) fan expander group. (B) hyrax expander group. Cone-beam computed tomography (CBCT) images were taken before and immediately after expansion procedure. Results: There was non-significant vertical movement of the maxilla for the 2 groups. On the transverse plane, there was more anterior expansion and posterior restriction for the fan group. However, the hyrax group showed significant posterior as well as anterior expansion. Both groups showed significant tipping between both sides posteriorly and anteriorly. Mandibular expansion was non-significant. Conclusion: Fan expander showed better results for children with cleft palate requiring anterior expansion only. Hyrax expander is better used for cases seeking for posterior and anterior expansion.(3160) Ahmed M. M. Sebaey, et al.

“…For this purpose, the maxillary expansion through Haas expander is one of main approaches used, aiming at reestablishing the transversal dimension of the maxilla, correcting the crossbite and to measure the cleft site [9,30]. Compared with the slow expansion, the rapid maxillary expansion results in a shorter treatment time [1].…”

Introduction: Cleft lip and palate (CLP) is the most frequent congenital malformation among the anomalies of the head and neck. The orthopedic/orthodontic treatment is included in the rehabilitation of these individuals, however there is no consensus in the literature regarding the ideal time for its beginning. Objective: To verify and characterize the profile of individuals with CLP treated at a reference hospital of the northeast of Brazil from 1998 to 2013 and its association with the beginning of the orthopedic/ orthodontic treatment. Material and methods: Through direct observation of medical records, panoramic radiograph, and study casts of 323 individuals, data regarding sex, cleft type, origin and age of beginning of the orthopedic/orthodontic treatment were surveyed and analyzed using the chi-square test, considering a 5% level of significance. Results: Most of the individuals had transforamen and the unilateral cleft was the most prevalent (p<0.05). Females were statistically more affected by post-foramen cleft and males by trans-foramen cleft (p<0.05). Most individuals with trans-foramen cleft and post-foramen cleft started the orthopedic/ orthodontic treatment between 8 and 12 years old (p<0.05). No statistically significant differences occurred relating the beginning
