Amaç: Dudak damak yarıklı bireylerde yumuşak doku kalınlıklarının değerlendirilmesi. Gereç ve Yöntemler: Retrospektif olarak yapılan bu çalışmaya, yaşları 16-18 arasında değişen toplam 70 birey dâhil edilmiştir. Tek taraflı dudak damak yarığı olan toplam 35 bireyin (ortalama yaş 16,8±3,5 yıl) dudak ve damak yarık operasyonları tamamlanmıştır. Yaş ortalaması 16,9±3,2 yıl olan 35 adet Angle Sınıf I kapanışa sahip birey ise kontrol grubu olarak değerlendirilmiştir. Çalışmada yer alan bireylere ait sefalometrik filmler üzerinde 13 adet referans noktasından yararlanılarak yumuşak doku kalınlıklarına ait toplam 9 adet ölçüm Dolphin Imaging Software Version 11.7 (Dolphin Imaging, California, ABD) yazılımı üzerinde gerçekleştirilmiştir. Elde edilen sonuçların değerlendirilmesinde Student t-testi kullanılmıştır. Bulgular: (A-A') kalınlığı (mm), (ULI-ULA) üst dudak kalınlığı (mm), (LLS-LLA) alt dudak kalınlığı (mm), (B-B') kalınlığı (mm) kontrol grubundan istatistiksel olarak anlamlı olacak şekilde az çıkmıştır (p<0,01, p<0,05). (Gl-Gl') yumuşak doku glabella kalınlığı (mm), (Na- Na') yumuşak doku nasion kalınlığı (mm), (Pog-Pog') yumuşak doku pogonion kalınlığı (mm), (Gn-Gn') yumuşak doku gnathion kalınlığı (mm), (Me-Me') yumuşak doku menton kalınlığı (mm) ise kontrol grubu ile benzerlik göstermektedir. Sonuç: Dudak damak yarıklı bireylerde, erken dönemde uygulanan primer cerrahi işlemler ve uygulanan farklı cerrahi teknikler; maksiller gelişimi ve yumuşak doku kalınlıklarını etkilemekte olup, bu durum ortodontik ve/veya ortognatik cerrahi tedavi planlamasında dikkate alınması gereken önemli bir durumdur. Ancak primer cerrahi işlemlere bağlı oluşan skar dokusunun etkisi dışında, dudak damak yarıklı bireylerde büyüme ve gelişimin normal bireylere göre geride olmasının nedenlerini saptamak için 'longitudinal' olarak planlanması gereken daha ayrıntılı çalışmalar gerekmektedir.

Objective: Evaluation of soft tissue thickness in individuals with cleft lip and palate. Material and Methods: A total of 70 individuals aged 16-18 years were included in this retrospective study. Cleft lip and palate operations and orthodontic treatments of 35 individuals (mean age 16.8±3.5 years) with unilateral cleft lip and palate were completed. 35 individuals with Angle class I occlusion with a mean age of 16.9±3.2 years were considered as the control group. Utilizing 13 reference points on the cephalometric films of the individuals included in the study, a total of 9 measurements of soft tissue thickness were performed on Dolphin Imaging Software Version 11.7 (Dolphin Imaging, California, USA). Student t test was used to evaluate the results obtained. Results: (A-A') thickness (mm), (ULI-ULA) upper lip thickness (mm), (LLS-LLA) lower lip thickness (mm), (BB') thickness (mm) found statistically significantly less (p<0.01, p<0.05) from the control group. (Gl-Gl') Soft tissue glabella thickness (mm), (Na-Na') soft tissue nasion thickness (mm), (Pog-Pog') soft tissue pogonion thickness (mm), (Gn-Gn') soft tissue gnathion thickness (mm), (Me-Me') soft tissue mentone thickness (mm) are similar to the control group. Conclusion: Primary surgical procedures and different surgical techniques applied in the early period in individuals with cleft lip and palate affects maxillary development and soft tissue thickness and this is an important condition that should be taken into account in orthodontic and/or orthognathic surgery treatment planning. However, apart from the effect of scar tissue due to primary surgical procedures, more detailed studies that need to be planned longitudinally are required to determine the reasons behind growth and development in individuals with cleft lip and palate compared to normal individuals.
