Silikon yüz protezlerinin deri ile renk uyumunun sağlanmasında dijital yöntemin görsel değerlendirilmesi
Abstract
Kulak,
göz, burun ve çevre dokularını da kapsayan defektler, kişileri toplum içine
çıkmaktan alıkoymakta ve bazen çok şiddetli psikolojik sorunlara yol
açmaktadır. Yüz protezleri; hastanın psikolojisinin iyileşmesine ve sosyal yaşama
katılmasına yardımcı olmaktadır. Doğal görünümün sağlanması için yüz protezinin
renk ve translüsensi özelliklerinin deriye benzer şekilde hazırlanması önemlidir.
Bu çalışmanın amacı silikon yüz protezlerinin deri ile renk uyumunun
sağlanmasında kullanılmak üzere yeni geliştirilen dijital bilgisayar destekli
sistemin görsel olarak değerlendirilmesidir.
Çalışmada
öncelikle “Referans renk” (RR) silikonlar oluşturuldu. Şeffaf haldeki silikon ilgili boyalar ile karıştırılarak 4 farklı
renkte silikon örnek hazırlandı. Her bir RR, sistemin spektrokolorimetre cihazı
ile ölçülerek elde edilen kod numarasının gösterdiği formülasyona göre renklendirildi.
“Sonuç renk” (SS) silikon olarak adlandırılan bu örneklerin RR ile benzerliği
22 mezuniyet sonrası doktora/uzmanlık eğitimi alan öğrenci tarafından görsel
olarak karşılaştırıldı. Elde edilen sonuçlar Ki-kare testi ile değerlendirildi.
Çalışmada
yüz protezlerinin deri ile renk uyumunun sağlanmasında kullanılan dijital
bilgisayar destekli sistemin sonuçlarının görsel olarak değerlendirilmesi
yaşları 24-32 arasında değişen (ortalama 27±2,3) toplam 22 doktora/uzmanlık
öğrencisi (17 kadın, 5 erkek) tarafından yapıldı. Değerlendirme sonuçları; 1.
Renk çifti için benzerlik puanının yeterli veya zayıf olduğunu, 2. 3. ve 4.
Renk çifti için benzerliğin genellikle yeterli ve iyi seviyede bulunduğunu
göstermektedir. Ki kare testi sonucunda
her bir renk çifti için verilen benzerlik puanlarının kadınlar ve erkekler
arasında anlamlı fark göstermediği gözlenmiştir (P>0,05).
Dijital
bilgisayar destekli sistem ile referans renkteki silikonların renginin taklit
edilerek sonuç renklerin elde edildiği çalışmamızda RR ve SR’lerin görsel
olarak karşılaştırması genellikle yeterli ve iyi düzeyde benzerlik ile
sonuçlanmıştır.

Visual Evaluation of Digital Method Used for Color Matching Between Silicone Facial Prostheses and Skin
Abstract
Auricular, nasal, orbital, and surrounding defects prevent people fitting into society
and sometimes cause psychological problems for the patients. Facial prostheses help
the patient to get better psychologically and join the social life. For natural
appearance, facial prostheses are required to be similar with surrounding skin with
regard to color and translucency. The aim of this study is the visual evaluation of
computer aided digital method used for color matching between silicone facial
prostheses and skin. In the study, first of all, “reference color” silicones were
formed. 4 different “Reference color” silicones were formed by mixing the paints
related to the silicone in the transparent form. Each reference color was measured
using the vehicle spectrocolorimeter of the system and a silicone coloring was
performed according to the code number given by spectrocolorimeter. These
silicones were labelled as “final color”. Similarity of each reference color and final
color silicone was assessed by 22 doctoral/speciality students visually. Data were
evaluated using Chi square test. Evaluation of digital method used for color
matching between silicone facial prostheses and skin were performed by a total of 22
doctoral/speciality students (17 women/5 men) whose ages were ranging between
24-32 (mean 27±2.3). Evaluation results; shows that similarity score for the first
color pair is enough or weak, for the second, third and forth color pair the similarity
is generally enough and satisfactory. As a result of Chi-square test, it was observed
that there were no meaningful difference between women and men given similarity
scores for each color pair (P>0.05). The results of the present study evaluating
computer aided digital method used for color matching between silicone facial
prostheses and skin revealed that visual similarity of reference color and final color
silicones were satisfactory or good.
