“…[1][2][3][4][5] Previous studies on airway morphology of patients with Class III malocclusion have been focused on the change of airway dimension after treatment with protraction headgear, 6 mandibular setback, 7,8,9 or bimaxillary surgery. 10 Ritcher et al 11 reported two cases of obstructive sleep apnea syndrome found in asymmetrical patients, indicating that upper airway obstruction could exist in patients with mandibular asymmetry.…”

Objective: To compare the three-dimensional (3D) morphology of the upper airway in skeletal Class III patients with and without mandibular asymmetry and to investigate the possible underlying correlations between the morphology of the upper airway and mandibular deviation. Materials and Methods: Cone-beam computed tomography images of 54 subjects with skeletal Class III malocclusion (ANB angle 0.48, Wits À5.58) were taken and 3D upper airway models were reconstructed using Dolphin 3D software. According to the distance (d) from symphysis menti to the sagittal plane, all subjects were divided into a symmetry group (d 2 mm) and an asymmetry group (d ! 4 mm). Based on the severity of mandibular deviation, the asymmetry group was divided into subgroup I (4 mm d ,10 mm) and subgroup II (d ! 10 mm). Cross-sectional linear distances, areas, and volumetric variables of the upper airway were measured in the 3D airway model. Results: Width of the inferior limit of the glossopharynx (P3W), cross-sectional area of the anterior limit of the nasal airway (P5S), and height of the glossopharynx (GPH) in the asymmetry group were significantly larger than in the symmetry group. As for subjects with severe mandibular deviation in subgroup II (d ! 10 mm), volume of the glossopharynx (GPV), total volume of the pharynx (TPV), length of the inferior limit of the velopharynx (P2L), and ratio of length to width of the inferior limit of the velopharynx (P2L/P2W) showed significantly negative correlations with mandibular deviation (r . 0.7, P , .05). Conclusions: In Class III subjects with severe mandibular asymmetry, the pharyngeal airway showed a tendency toward constriction and presented a more elliptical shape as mandibular deviation became more severe (P , .01).

ÖZET Amaç: Bu kesitsel çalışmanın amacı ebeveynlerin pediatrik uyku apnesi ile ilgili bilgilerini ve ortodontistin bu hastalığın teşhis ve tedavisindeki yeri ile ilgili fikirlerini değerlendirme-ktir. Gereç ve Yöntem: Pediatrik uyku apnesi hakkındaki farkın-dalık ve görüşleri ölçmek üzere tasarlanmış bir anket, çocuklarının ortodontik tedavisi için bir üniversite ortodonti kliniğine başvuran uygun örneklem grubu ebeveynlere uygulandı. Elde edilen veriler ortalama ve sıklıkları içeren tanım-layıcı istatistikler ile analiz edildi. Demografik değişkenler ile sorgulanan bilgi maddeleri arasındaki korelasyonlar Pearson ki-kare testi kullanılarak incelendi. Bulgular: Anket toplam 260 ebeveyn tarafından cevaplandı. (Ortalama yaş: 40,7±6,6 yıl, 169 kadın, 91 erkek). Ebeveynlerin çoğu, diş hekimleri ve ortodontistlerin tıbbi hastalık riskleri yönünden çocuklarında değerlendirme yapmasının çok önemli olduğu görüşündeydi (sırasıyla %76,5 ve %76,2). Ebeveynler aynı zamanda ortodontistin çocuklarını uyku apnesi riski yönünden değerlendirmesini isteyeceklerini (%92,7) ve eğer ortodontist yönlendirirse uyku apnesi açısından değerlendirilmek üzere çocuklarını doktora götüreceklerini (%97,5) belirttiler. Çoğu ebeveyn pediatrik uyku apnesi hakkında temel düzeyde bir bilgiye sahip olmasına rağmen, bu hastalığın etyolojisi, semptomları, teşhisi, sonuçları ve tedavileri hakkında bilgileri yoktu. Artmış eğitim seviyesi, pediatrik uyku apnesi hakkındaki bilgi düzeyi ile anlamlı düzeyde ilişkiliydi (p<0,05). Sonuç: Sonuçlar ortodonti kliniğine başvuran ebeveynlerin çocuklarının uyku apnesi yönünden incelenmesine olumlu baktığını göstermiştir. Ancak bilgi düzeylerinin düşüklüğü, ebeveynler arasında pediatrik uyku apnesi farkındalığını arttırmak için eğitsel yöntemlerin geliştirilmesi gerekliliğini ortaya koymuştur.

Materials and Methods: A questionnaire designed to evaluate awareness and views about pediatric sleep apnea was given to a convenience sample of parents visiting a university clinic for the orthodontic treatment of their children. Data were analyzed using descriptive statistics including means and frequencies. Pearson's chi-square statistics were used in order to determine the correlation between knowledge items questioned and demographic variables. Results: The survey was completed by 260 parents (mean age: 40.7±6.6 years, 169 female, 91 male). The majority of parents thought it was very important for dentists and ortho-ÖZGÜN ARAŞTIRMA

“…In severe conditions, children with OSAHS may have retarded growth and development, craniofacial abnormalities (Flores-Mir et al, 2013), cognitive impairment, and cardiovascular system diseases (Bhattacharjee et al, 2009) because of nocturnal recurrence of apnea and hypopnea and a more frequent and persistent reduction of SpO 2 during the rapid eye movement phase of sleep. The classical risk factor for OSAHS in normal weight children is enlargement of the adenoids and tonsils, which differs from that in adult patients.…”

ABSTRACT. The purpose of this study was to investigate the changes in the humoral and cellular immunity of children with obstructive sleep apnea-hypopnea syndrome and hypertrophy of tonsils before and after plasma-mediated temperature-controlled radiofrequency ablation treatment. Fifty-seven children suffering from obstructive sleep apnea-hypopnea syndrome and with hypertrophy of tonsils were enrolled in this study. Thirty-seven children were grouped in the partial tonsillectomy group and 20, in the tonsillectomy group. The levels of CD3 + , CD4 + , CD8 + , and CD4 + /CD8 + were measured for cellular immunity, and the levels of IgG, IgA, and IgM were measured for humoral immunity. Blood samples were collected before and 1 and 3 months after the operation. The IgG, IgA, and IgM levels in the tonsillectomy group were significantly decreased 1 month after the operation, and recovered to the normal levels within 3 months of the operation (P < 0.05). However, the levels of IgG, IgA, and IgM in the partial tonsillectomy group decreased slightly, without a significant difference (P > 0.05). The cellular immunity of the 2 groups was not statistically different pre-and post-operation (P > 0.05). The results from the present study indicate that partial tonsillectomy by plasmamediated temperature-controlled radiofrequency ablation did not impact on the humoral and cellular immunity of children.
