“…Since different surgical techniques might result in different cephalometric outcomes (Tome et al, 2016), the samples were also matched based on the protocols of primary surgeries. Although skeletal effects resulting from orthopedic treatment are greater when performed after bone grafting (Zhang et al, 2018), the reason to choose patients without bone graft at the age of 9 to 12 years was based only on the fact that the number of patients in this situation was greater than those who underwent RME and MP treatment after bone grafting.…”

Objective: To evaluate the efficacy of rapid maxillary expansion (RME) and maxillary protraction (MP) in patients with unilateral complete cleft lip and palate (UCLP) using the Goslon yardstick index. Design: Retrospective study. Patients: Dental casts of 34 Goslon 3 (G3) and Goslon 4 (G4) patients treated with RME and MP were evaluated which composed the treated sample (S1). The dental cast were taken before the RME (T1) and immediately after the use of face mask for MP was suspended (T2). In order to verify the stability of the treatment, dental casts of 17 of these patients were evaluated 1 year after the treatment was finished (T3). For the control sample (S2), dental casts of 20 untreated G3 and G4 patients were evaluated. Results: At T2, 85.7% of study sample patients initially G3 and 70% of patients initially G4 obtained improvement in occlusal index. At T3, the majority of patients initially classified as G3 and G4 returned to the same classification as in the beginning of the treatment. The evaluation of the control sample showed that patients initially classified as G3, 55.6% continued at this initial index, and 44.4% had it worsened. Those initially G4, 100%, continued at this initial index. Conclusion: The immediate result of RME and MP was satisfactory, and despite the instability of these results, the outcome of this treatment option was better than the untreated sample.

“…Early alveolar bone grafting leads to more efficient application of orthopedic therapy in patients with clefts and concurrent maxillary hypoplasia. 25 However, treatment outcomes are invariably affected by patient responses to surgical intervention and treatment, as well as the reference points chosen by different investigators for angular and linear measurements. There is still no consensus on how the mandible will be affected long term by surgical, orthopedic, and orthodontic treatment in patients with CLP.…”

Objectives To examine the relationship between mandibular volume and craniofacial morphology in patients with cleft lip and palate using cone beam computed tomography (CBCT) and to compare these findings with control (noncleft) patients undergoing CBCT for other purposes during the deciduous dentition period. Materials and Methods Eighty-four patients were categorized into the unilateral cleft lip and alveolus (UCLA) group (n = 25; mean age, 4.60 ± 0.40 years), unilateral cleft lip and palate (UCLP) group (n = 23; mean age, 4.52 ± 0.39 years), bilateral cleft lip and palate (BCLP) group (n = 22; mean age, 4.54 ± 0.37 years), and control group without cleft (n = 14; mean age, 5.19 ± 0.52 years). Mandibular volume and craniofacial cephalometric measurements were obtained using CBCT. All measurements were assessed by analysis of covariance (ANCOVA) using Bonferroni post hoc pairwise comparison tests. Results ANCOVA revealed no statistically significant differences in mandibular volume among the groups. SNA° and ANB° were significantly larger in the UCLA and BCLP groups than in the control group. SN-MP° was smallest in the UCLA group. Co-A in the UCLP group was shorter than in the UCLA and BCLP groups. Go-Gn was shortest in the UCLP and BCLP groups compared with the control group. Conclusions Three-dimensional evaluation of craniofacial morphology using CBCT can provide valuable information on malocclusion and other dentoskeletal problems among patients with CLP.

“…Patients who had more than 4 mm of A point advancement were included in the experimental group, because this amount of advancement shows a therapeutic effect of one cusp width correction. Since less than 2 mm of A point advancement might be comparable to natural growth changes in patients with CLP, 21 these patients were included in the positive control group.…”

Effects of the long-term use of maxillary protraction facemasks with skeletal anchorage on pharyngeal airway dimensions in growing patients with cleft lip and palate

Objective To investigate the effects of the long-term use of a maxillary protraction facemask with miniplate (FM-MP) on pharyngeal airway dimensions in growing patients with cleft lip and palate (CLP). Methods The study included 24 boys with CLP (mean age, 12.2 years; mean duration of FM-MP therapy, 4.9 years), divided into two groups according to the amount of A point advancement to the vertical reference plane (VRP): Group 1, > 4 mm; Group 2, < 2 mm; n = 12/group. After evaluating the skeletodental and airway variables using lateral cephalograms acquired before and after FM-MP therapy, statistical analyses were performed. Results Group 1 showed greater forward and downward displacements of the posterior maxilla (posterior nasal spine [PNS]-horizontal reference plane [HRP]; PNS-VRP), greater increase in ANB, more forward tongue position (tongue tip-Pt vertical line to Frankfort horizontal plane), and greater increase in the oropharynx (superior posterior airway space [SPAS]; middle airway space [MAS]) and upper nasopharynx (PNS-adenoid2) than did Group 2. While maxillary advancement (A-VRP and PNS-VRP) correlated with increases in SPAS, MAS, and PNS-adenoid2, downward displacement of the PNS (PNS-HRP) correlated with increases in SPAS, MAS, PNS-adenoid1, and PNS-adenoid2, and with a decrease in vertical airway length (VAL). Mandibular forward displacement and decrease in mandibular plane correlated with increases in MAS. Conclusions FM-MP therapy had positive effects on the oropharyngeal and nasopharyngeal airway spaces without increases in VAL in Group 1 rather than in Group 2. However, further validation using an untreated control group is necessary.
