Abstract

Aim: The aim of this retrospective study was to evaluate the changes in maxillary arch parameters and symmetry after nasoalveoler molding in unilateral total cleft lip and palate infants. Material and Method: For this purpose, 5 female and 10 male infants 5-75 days previously treated with nasoalveoler molding were included. Strip bands were used in all cases together with the molding appliances. Infants were checked weekly until cleft segments were closed completely. Pretreatment and post molding photographs and casts were obtained. Amount of cleft, transversal distance of cleft, anterior and posterior arch widths, anterior and total arch lengths and asymmetry index were calculated on the study models. Paired t test was used to investigate whether there are any differences statistically between the pretreatment and posttreatment mean values, while Wilcoxon sign test was used in terms of differences between the median values. Results: Cleft widths decreased and cleft segments were closed each together after nasoalveoler molding in all cases. Anterior arch width did not show any significant change while posterior arch width increased statistically significant 2 mm . Anterior arch length decreased with a mean of 1,8 mm, while total arch length did not show any changes. The change of asymmetry index was found statistically significant. Conclusion: Cleft segments were aligned properly after nasoalveoler molding therapy and an improvement was obtained in arch symmetry

Nasoalveolar molding uygulanan unilateral dudak damak yarıklı bebeklerde ark boyutlarının ve ark asimetrisinin değerlendirilmesi

Abstract

Amaç: Bu retrospektif çalışmanın amacı unilateral total dudak damak yarıklı bebeklerde nazoalveoler molding sonrası maksiller ark parametrelerindeki ve simetrideki değişiklikleri incelemektir. Materyal ve Metod: Bu amaçla çalışmaya daha önce nazoalveoler molding tedavisi görmüş; 5 kız, 10 erkek bebek 5-75 günlük dahil edilmiştir. Tüm bebeklere nazoalveoler molding apareyi ve strip bantlar uygulanmıştır. Yarık segmentler birleşinceye kadar bebekler her hafta kontrol edilmiştir. Başlangıç ve nazoalveoler molding sonrası model ve fotoğrafları elde edilmiştir. Modeller üzerinde, başlangıç ve molding sonrası yarık ve transversal yarık uzaklığı miktarları, anterior ve posterior bölge ark genişlikleri, anterior ve total ark uzunlukları ve asimetri indeksi hesaplanmıştır. Başlangıç ve bitiş ortalama değerleri arasında istatistiksel olarak anlamlı fark olup olmadığı Bağımlı t testiyle araştırılırken, ortanca değerler yönünden farkın önemliliği Wilcoxon işaret testiyle incelenmiştir. Bulgular: Yarık hattı tüm vakalarda küçültülmüş ve segmentler birbirine tamamen yaklaştırılmıştır. Anterior bölge ark genişliği önemli bir değişiklik göstermezken, posterior bölge ark genişliği istatistiksel olarak önemli ölçüde artış göstermiştir 2 mm . Anterior ark
