“…Because CBCT has been shown to be a reliable method for assessing dehiscences and fenestrations, we decided to use these images in cleft patients, a technique that has not been reported previously. Consistent with previous studies 4,5,[18][19][20][21][22][23][24] showing the high reliability of CBCT for 2-D and 3-D measurements, agreement was 100% for the detection of dehiscences and fenestrations. Although Sun et al 12 reported that this method might overestimate the actual measurements, the technique was reported to have the highest sensitivity and diagnostic accuracy for detecting various periodontal defects.…”

“…Their results are consistent with those of the present study, in which the dehiscence rate for centrals on the cleft site was significantly higher than that in the control group (43.2% and 13.7%, respectively). In a study 22 that analyzed these defects in different sagittal malocclusion groups, the incidences of fenestrations for maxillary central incisors were 23.1% in Class I, 18.5% in Class II, and 21.1% in Class III malocclusion patients. In another study 9 that evaluated these defects according to vertical growth patterns, the presence of fenestrations for the same tooth were similar in hyperdivergent (21.1%) and normodivergent (22.4%) groups.…”

Objective: To evaluate the presence of dehiscence and fenestration defects around anterior teeth in the cleft region and to compare these findings with the noncleft side in the same patients using cone beam computed tomography (CBCT). Materials and Methods: CBCT scans of 44 patients (26 males, 18 females; mean age, 14.04 6 3.81 years) with unilateral cleft lip and palate (UCLP) were assessed to define dehiscences and fenestrations of the anterior teeth in both cleft and noncleft sides of the UCLP patients and a control group of noncleft patients (51 patients; 21 males, 30 females; mean age, 14.52 6 1.16 years). Data were analyzed using Pearson's x 2 and Student's t-test. Results: The prevalence of dehiscences at the maxillary central incisors, lateral incisors, and canines teeth were 43.2%, 70.6%, and 34.1% on the cleft side and 22.7%, 53.1%, and 27.3% on the noncleft side of UCLP patients, and 13.7%, 7.8%, and 13.7% in controls, respectively (statistically no difference between the sides of cleft patients). The cleft patients had a statistically significantly higher prevalence of dehiscences than did the controls on both the cleft and noncleft sides (P , .05), except for the maxillary central incisors. Fenestrations for these teeth were significantly more common on the cleft side in UCLP patients compared with controls (P , .05), whereas the difference for maxillary lateral incisors was not statistically significant. Conclusions: Patients with UCLP showed a higher prevalence of dehiscence and fenestration defects around the maxillary anterior teeth. (Angle Orthod. 2016;86:431-436.)

“…This is in agreement with a previous study where the posterior wall of the pharynx was used to delineate the posterior airway margin. 27 Anteriorly, superiorly and inferiorly, identification of the pharyngeal airway margins is much more complicated owing to the close association with mobile soft tissues. 30,36,37 However, hard-tissue points that can be used to develop margins that approximated the softtissue boundaries are easily identifiable ( Table 2).…”

Objectives: Recently, studies have performed three-dimensional analyses of upper airways in children. However, there was a lack of airway delineation according to anatomical boundaries and/or easily mobile soft-tissue landmarks were used. The aim of the present study was to define new upper airway margins in children on CBCT according to anatomical bony landmarks and to validate the method. Methods: 25 scans were randomly selected from a larger database containing CBCT scans of children prior to orthodontic treatment (14 girls and 11 boys; mean age, 10.9 ± 2.5 years). Scans were evaluated by two observers. Specific head positioning and virtual orientation protocols were adopted and greyscale thresholding was established for each patient. Volume and minimum cross-sectional area of the oropharynx were calculated. Intra-and interobserver reliability were assessed by reassessment of the CBCTs 2 weeks later. Results: The new airway margins were defined superiorly by a line passing through the palatal plane (anterior nasal spine to posterior nasal spine) extending to the posterior wall of the pharynx, inferiorly by a line passing from the anterosuperior edge of C4 to menton, anteriorly by a line passing from the soft palate to menton, posteriorly and laterally by the respective pharyngeal walls. Method error for airway volume and minimal cross-sectional area was #2.00%, and intra-and interobserver reliability ranged from 0.99 to 1.00. Conclusions: The proposed protocol utilizes easily identifiable bony landmarks to delineate the upper airway on cone beam scans of children and was found to be reliable and reproducible.

Objectives/Hypothesis Individuals with orofacial clefts often experience respiratory problems because of nasopharyngeal abnormalities. Pharyngeal airway morphology is thought to differ among the various cleft types. We measured three‐dimensional (3D) airway volume using cone‐beam computed tomography (CBCT) analysis to evaluate and compare pharyngeal airways in Japanese preschoolers with and without orofacial clefts. Study Design Retrospective case‐control study. Methods We enrolled 83 subjects (37 boys, 46 girls; mean age = 4.66 ± 0.56 years) with nonsyndromic orofacial clefts and 16 noncleft healthy subjects (seven boys, nine girls; mean age = 5.30 ± 0.52 years) as controls. The subjects were divided into five groups. Four groups were based on the cleft type: isolated cleft palate, unilateral cleft lip and alveolus), unilateral cleft lip and palate, and bilateral cleft lip and palate. The fifth group included the noncleft controls. All subjects were examined with CBCT, and the 3D airway volume was measured. We analyzed group differences statistically using analysis of covariance with the Bonferroni post hoc pairwise comparison tests for the corrected means. Results Compared with the noncleft group, each cleft group exhibited significantly decreased total and nasal airway volumes and increased superior and inferior pharyngeal airway volumes. The differences were all statistically significant. Conclusions Our findings suggest that anatomical differences exist in pharyngeal airway volumes among various cleft groups and in those without a cleft.
