DİJİTAL PANORAMİK GÖRÜNTÜLERDE UZAMIŞ STİLOİD PROSES PREVALANSI VE STİLOİD PROSES UZUNLUĞUNUN YAŞ VE CİNSİYETLERE GÖRE DEĞERLENDİRİLMESİ

Amaç: Bu çalışmanın amacı seçili bir hasta grubuna ait panoramik görüntülerde uzamış stiloid proses (USP) prevalansının belirlenmesi ve hastaların stiloid proses (SP) uzunluğunun yaş ve cinsiyetlere göre dağılımının değerlendirilmesidir. Gereç ve yöntem: Ağız Diş ve Çene Radyolojisi Anabilim Dalına müracaat eden 16-60 yaş aralığında 200 hastanın (100 kadın, 100 erkek) dijital panoramik görüntüleri veri tabanından elde edilerek çalışma gru- bu oluşturuldu. Bireyler yaşlarına göre 5 gruba ayrıldı ve her grupta eşit sayıda hasta olacak şekilde görün- tüler sistemden rastgele seçildi. Her panoramik görün- tü üzerinde sağ ve sol taraf SP uzunluğu CliniView programında cetvel aracı kullanılarak ölçüldü. Uzunluk ölçümünde SP’nin temporal kemikten ilk ayrıldığı yer ile en uç noktası referans noktalar olarak belirlendi. Uzunluğu 30 mm’den fazla olan ölçümler USP olarak kabul edildi. Elde edilen veriler SPSS 17.0 programına aktarılarak gruplar arası istatistiksel karşılaştırma yapıldı. Bulgular: USP prevalansı %15 olarak bulundu. USP görülen hastaların 18’inin erkek (%60), 12’sinin (%40) kadın olduğu tespit edildi. Sol SP uzunluğu ortalama 24,64 ± 4,83 mm, sağ SP uzunluğu ortalama 24,35 ± 4,84 mm olarak ölçüldü. Cinsiyetler ve yaş grupları için ölçüm değerlerinde istatistiksel olarak anlamlı fark bu- lunmadı (p> 0,05). SP uzunluğunun yaş ile anlamlı korelasyon göstermediği tespit edildi. Sonuç: Seçili hasta grubunda USP prevalansı ve orta- lama SP uzunluğu değerleri literatürde bildirilen değer aralığında saptanmıştır. Ayrıca SP uzunluğunun yaşa ve cinsiyete bağlı anlamlı fark göstermediği tespit edilmiştir. Çalışma sonuçlarının doğruluğu daha geniş çalışma popülasyonunda ve farklı görüntüleme yön- temleri kullanılarak araştırılmalıdır.Anahtar Kelimeler: Stiloid proses, Eagle sendromu, temporal kemik, panoramik görüntüTHE PREVALANCE OF ELONGATED STYLOID PROCESS IN DIGITAL PANORAMIC IMAGES AND EVALUATION OF STYLOID PROCESS LENGHT ACCORDING TO GENDERS AND AGE GROUPS Aim: The purpose of the present study is to determine the prevalence of elongated styloid process (ESP) and investigate the distribution of styloid process (SP) length according to genders and age groups in digital panoramic images of a selected patient population. Materials and Methods: A total of 200 panoramic images of patients (100 females, 100 males) aged between 16-60 years were selected from the database of Oral and Maxillofacial Radiology Department. Patients were equally divided into five groups according to their ages. Length of right and left SPs were measured on digital panoramic images by an oral and maxillofacial radiologist using ruler tool in CliniView software. The point where the SP first separated from the temporal bone and the most apical point of SP were identified as reference points for measurements. SP measuring more than 30 mm was considered elongated. Obtained variables were entered SPSS 17.0 software for statistical analysis of measurements. Results: Prevalence of ESP was found to be 15%. Among patients with ESP 18 (60%) were male and 12 (40%) were female. Mean length of SP was 24,64 ± 4,83 mm on left side and 24,35 ± 4,84 mm on right side. There was no significant difference between genders and age groups for SP measurements (p>0,05). Moreover, there was no significant correlation between age of the patients and SP length. Conclusion: The ESP prevalence and mean SP length measurements in the selected patient group were in the range of reported values in the literature. Also, it was determined that the SP length does not differ significantly depending on gender and age. The accuracy of the study results should be furtherly investigated in the larger study population with different imaging modalities.Keywords: Styloid process, Eagle’s Syndrome, temporal bone, panoramic image
