Background: To examine the changes in pharyngeal airway dimension and hyoid bone position with the effect of rapid maxillary enlargement during the treatment of skeletal Class II malocclusion with functional appliances.
Methods: Patients with skeletal Class II malocclusion were divided into two groups; Group 1 consisted of 25 patients (8 males, 17 females) with a mean age of 11.41±1.13 who treated with twin-block appliance with rapid maxillary expansion appliance and Group 2 who only received twin-block therapy consisted of 25 patients (12 males, 13 females) with a mean age of 11.92±0.65. In this study, 11 angular and 3 linear measurements were used for skeletal evaluation of maxillary and mandibular on cephalometric X-rays of initial and intermediate records of 50 patients and 13 linear measurements were performed for pharyngeal airway evaluation.
Results: According to the intra-group t test results, in skeletal evaluation of the maxillary and mandibular, 8 angular and 2 linear measurements for group 1, 9 angular and 2 linear measurements for group 2, in pharyngeal evaluation all measurements of group 1 and 11 linear measurements for group 2 were significant differences (P < .05). According to the intergroup t test results, there were significant differences in skeletal assessment and pharyngeal airway evaluation (P < .05).
Conclusion: While the contribution of RME to the increase of pharyngeal airway dimensions was shown, the effect of the functional appliances on this region is greater.

İskeletsel Sınıf II Tedavisinde Hızlı Üst Çene Genişletmesinin Hava Yolu Boyutlarına Etkisi

Amaç: Bu çalışmanın amacı, iskeletsel Sınıf II maloklüzyona sahip hastaların tedavisinde kullanılan fonksiyonel apareyler sırasında hızlı üst çene genişletmesinin, farengeal hava yolu boyutlarına ve hyoid kemiğin pozisyonundaki değişimlere etkisinin değerlendirilmesidir.
Gereç ve Yöntemler: İskeletsel sınıf II maloklüzyona sahip hastalar iki gruba ayrıldı; Grup 1 hızlı üst çene genişletmesi ile birlikte twin blok tedavisi gören yaş ortalaması 11,41±1,13 olan 25 hastadan (8 erkek,17 kız) ve Grup 2 sadece twin blok tedavisi gören yaş ortalaması 11,92±0,65 olan 25 hastadan (12 erkek, 13 kız) oluşmaktadır. Çalışmamızda, 50 hastanın başlangıç ve ara kayıt sefalometrik röntgenleri üzerinde alt ve üst çeneye ait iskeletsel değerlendirme için 11 açısal 3 çizgisel ölçüm, farengeal havayolu değerlendirmesi için 13 çizgisel ölçüm gerçekleştirildi. İstatistiksel analiz için grup içi bağımlı örneklem t testi, gruplar arası bağımsız örneklem t testi kullanıldı.
Bulgular: Grup içi bağımlı örneklem t testi sonuçlarına göre alt ve üst çeneye ait iskeletsel değerlendirmede grup 1 için 8 açısal 2 çizgisel ölçümde, grup 2 için 9 açısal 2 çizgisel ölçümde, farengeal havayolu değerlendirmesinde grup 1 için kullanılan tüm çizgisel ölçümlerde, grup 2 için 11 çizgisel ölçümde anlamlı fark bulundu(p < 0,05). Gruplar arası bağımsız örneklem t testi sonuçlarına göre iskeletsel değerlendirmede farengeal havayolu değerlendirmesinde anlamlı farklılıklar bulundu(p < 0,05).
Sonuç: Gruplar arası değerlendirmede üst ve orta farengeal hava yolu boyutlarında istatistiksel olarak fark saptandı. Hızlı üst çene genişletmesi uygulanmış fonsiyonel aparey tedavisi, farengeal hava yolu ve hyoid kemiğin pozisyonunu daha fazla etkilemektedir.
