“…22 Maxillary expansion does not only correct the posterior crossbite, which improves the skeletal and dental transverse relationships, but it was reported also to increase the pharyngeal airway volume which improves the respiratory capacity improving both breathing and speech. 7,23,24 BAMP was first introduced by Hugo de Clerck as an alternative for facemask therapy for the correction of maxillary deficiency. 8,9 Recent studies investigated its effects in patients with CLP and it proved to be an effective treatment modality.…”

Objective: To assess three-dimensionally (3D) the short-term effects of Bone-anchored maxillary protraction (BAMP) with and without maxillary expansion on the oropharyngeal airway volume in patients with surgically repaired complete unilateral cleft lip and palate (UCLP).Material and methods: Twenty growing Class III maxillary deficient patients (mean age 10.8±1.2) with complete UCLP were treated with BAMP protocol. The cone-beam computed tomography scans that were taken before start of treatment and after 9-months of treatment were retrieved from the archive of the Orthodontic Department, Ain Shams University. Patients were divided into two groups: Group I were treated with BAMP alone. Group II were treated with BAMP preceded by maxillary expansion. The oropharyngeal airway volume was measured before treatment and after 9 months. Statistical analysis was carried to find the difference between the two groups. Results:The results showed no significant change in the oropharyngeal airway volume in Group I treated with BAMP alone. On the other hand, a significant increase in the oropharyngeal airway volume was observed in group II in which BAMP was preceded by maxillary expansion. Conclusion:BAMP protocol alone was not able to produce significant change in the oropharyngeal airway volume in patients with complete UCLP. However, when it was preceded by maxillary expansion, a significant increase in the oropharyngeal airway volume was observed.

“…Adenoid hypertrophy was clinically evaluated using the adenoid-to-choanal opening ratio as a percentage, divided into three groups: groups 1-3 represented adenoid tissue occupying more than 50%, 50-75%, and more than 75%, respectively. (29) According to Rana et al (25) assessment methods, we had calibrated the orientation of the images by using (26) the manual option in the Dolphin imaging program. The midsagittal plane from Ricketts's analysis was adjusted in the frontal plane as illustrated in Figure 3.…”

“…Using Dolphin 3D analysis, the clinician measured the volume and the most constricted axial area of the upper pharyngeal airway (25) , employing the same anatomical landmarks as in 2D images as illustrated in Figure 4 and To ensure accuracy and minimize errors in measurement and digital programming, each value was measured three times, and the mean was calculated. Intra-examiner Additionally, an independent sample t-test was used to assess mean differences between the UCLP and non-cleft groups.…”

“…(20,21) Muntz et al, (1) Oosterkamp et al, (22) and Celikoglu et al (23) explained that cleft patients have a smaller pharyngeal airway size and volume compared to normal children. However, controversially, Ceilo et al (24) and Rana et al (25) found no difference in the upper pharyngeal airway between normal and abnormal children. Several studies have been conducted to evaluate the upper pharyngeal airway in an upright position (25,26) , while sleep problems are typically identified during sleep or in the supine position.…”

Objectives: This study aimed to evaluate differences in the upper pharyngeal airway morphology between Thai children with repaired unilateral cleft lip and palate (UCLP) and Thai non-cleft children. Methods: This prospective study used cone beam computed tomography (CBCT) and polysomnography (PSG) studies. The subjects were 34 children with UCLP (21 males and 13 females; mean age 8.94±1.87); and 32 non-cleft children (20 males and 12 females; mean age 10.03±1.91). The Dolphin imaging software measured the volume and the most constricted cross-sectional airway (version 11.7 premium). Results: An independent sample t-test showed that the differences between groups were significant. The means of oropharyngeal (p=0.003), hypopharyngeal (p=0.020), and total volume (p=0.013) in UCLP children were lower than those in non-cleft children. Furthermore, the most constricted axial area of the oropharyngeal airway in UCLP children was narrower than that in non-cleft children (p=0.004). Conclusions: The volume and most constricted axial area of the upper pharyngeal airway in Thai UCLP children were significantly smaller than those in Thai non-cleft children
