Abstract

Background: Rapid maxillary expansion (RME) is commonly used in treatment of maxillary constriction. The aim of this study was to evaluate changes in the nasopharyngeal area after RME treatment. Methods: RME group was consisted of 20 patients (12 girls and 8 boys, mean age, 12.34±1.26) who had bilateral transversal constriction. These patients treated by full coverage acrylic bonded appliances. Twenty patients (13 girls and 7 boys, mean age, 12.68±1.15) who had no sagittal and transversal direction anomalies were evaluated as control group. Patients and control subjects’ records were selected our clinic archives. Assessments of the patients were made with cephalometric measurements that were recorded at the beginning and at the end of treatment. Paired samples and independent sample t-tests were used for statistical comparison. Results: After RME treatment, adenoidal area, aerial area and total area were increased significantly in comparison with pretreatment levels (P < 0.05). Compared to control group, it has been found that adenoidal area and total area were increased in the study group (P < 0.05), but increase in aerial area was not significant (P > 0.05). Conclusion: RME affects nasal airway positively and it causes to a significant increase in nasopharyngeal area.

Özet

Amaç:Hızlı üst çene genişletme (HÜÇG) işlemi üst çene darlıkların giderilmesinde yaygın olarak kullanılır. Bu çalışmanın amacı HÜÇG tedavisi sonrası nazofarengeal alandaki değişimleri değerlendirmektir.Gereç ve Yöntemler:Çalışma grubu çift taraflı transversal darlığa sahip 20 hastadan (12 kız ve 8 erkek, ortalama yaş, 12.34±1.26) oluşturuldu. Bu hastalar tüm dişleri kaplayan akrilik aparey ile tedavi edilmiştir. Kontrol grubu için ise sagittal ve transversal yön anomalisi olmayan 20 birey (13 kız ve 7 erkek,ortalama yaş, 12.68±1.15) seçildi.Hastalar ve kontrol grubu kayıtları klinik arşivimizden seçildi. Değerlendirmeler tedavi başında ve sonunda kaydedilen sefalometrik ölçümlerle yapıldı. İstatistiksel karşılaştırma için, bağımlı ve bağımsız örnek t-test leri kullanıldı.Bulgular:Tedavi sonucunda, tedavi öncesine kıyasla, adenoidal alan, aerial alan ve toplam alan anlamlı derecede artmıştır (P < 0.05). Kontrol grubuyla karşılaştırıldığında çalışma grubunda, adenoidal alan ve toplam alanda artış bulunmuştur (P < 0,05), fakat aerial alandaki artış istatiksel olarak anlamlı değildir (P > 0,05).Sonuç:HÜÇG tedavisi nazofarengeal hava yoluna pozitif etki eder ve nazofarengeal alanda anlamlı derecede artışa sebep olur.
