Abstract

Objective: The aim of this study is to evaluate usefulness of results of measurements via computerized tomography of frontal sinus dimensions in sex determination.Materials and methods: In Bakırköy Training and Research Hospital, subjects who had performed maxillofacial computed tomography were included. Transvers diameters (width) were measured from axial images and anterior-posterior (depth) and cephalo-caudal diameters (height) were measured from sagittal reformatted images. Measurements were taken for both left and right frontal sinuses. The size of frontal sinuses on both sides were obtained using these parameters. These values were evaluated with independent t test. The variables were evaluated discrimination function analysis Results: 400 subjects were evaluated (200 males and 200 females) for the study (female/male: 200/200, mean age: 30.12 ± 10.2 years of age). All values for left and right transvers, cephalo-caudal and antero-posterior measurements showed significant differences between the sexes of the subjects. Males had significant increased values than females (p<0.001). In single discrimination analysis, the lowest accuracy rate was 55.5% for LH in males and 59.5% for RT in females. Highest observed accuracy rates were LAP (77.5%) and RAP (77%) in females and LAP (69%) in males. When, only the RAP and LAP values were added together, the accuracy rate was detected as 77.5% in females and 70.5% in males. If all measured values were included in the stepwise discrimination analysis, then the accuracy rate was detected as 80.5% in females and 71.5% in males.Conclusion: The frontal sinus morphometric studies, particularly in multicultural societies, can provide important data for research. The data will be useful for forensic specialists and anthropologists, as well as craniofacial surgeons and dentists who perform endoscopic and surgical procedures in related anatomical structures.

Özet

Amaç: Bu çalışmanın amacı, frontal sinüs boyutlarının bilgisayarlı tomografi ile yapılan ölçüm sonuçlarının, cinsiyetin belirlemesinde yararlılığını değerlendirmektir.Gereç ve Yöntem: Çalışmaya Bakırköy Dr. Sadi Konuk Eğitim ve Araştırma Hastanesi'nde maksillofasiyal bilgisayarlı tomografi çekimi yapılan olgular dahil edildi. Transvers çapları (genişlik; RT ve LT) eksensel görüntülerden, ön-arka (derinlik; RAP ve LAP) ve sefalo-kaudal çaplardan (yükseklik; RH ve LH) sagital yeniden biçimlendirilmiş görüntülerden ölçüldü. Hem sol hem de sağ frontal sinüsler için ölçümler yapıldı. Her iki taraf frontal sinüs boyutu bu parametreler kullanılarak elde edildi. Değerler bağımsız t testi ile., değişkenler diskriminant fonksiyon analizi ile değerlendirildi.Bulgular: Çalışma için 400 olgu değerlendirildi (200 erkek 200 kadın, ortalama yaş: 44 ± 18.0) Sol ve sağ ölçümlerin tüm değerleri cinsiyete göre anlamlı fark gösterdi. Erkekler, kadınlara kıyasla belirgin artmış bir ölçüm değeri taşıyordu. (p <0.001) Tekli diskriminasyon analizinde en düşük doğruluk oranı erkeklerde LH için %55.5, kadınlarda RT için %59.5 idi. Kadınlarda LAP (%77.5) ve RAP (%77) ve erkeklerde LAP (%69) en yüksek doğruluk oranlarına sahipti. Yalnızca RAP ve LAP değerleri eklendiğinde diskriminasyon analizinde doğruluk oranı kadınlarda %77.5, erkeklerde %70.5 olarak tespit edildi. Aşamalı diskriminasyon analizinde ölçülen değerlerin hepsi dahil edildiğinde, doğruluk oranı kadınlarda %80.5, erkeklerde %71.5 olarak tespit edildi.Sonuç: Özellikle çok kültürlü toplumlarda frontal sinüs morfometrik çalışmaları kimliklendirme araştırmaları için önemli veriler sağlayabilir. Veriler, adli tıp uzmanları ve antropologların yanı sıra ilgili anatomik yapılarda endoskopik ve cerrahi işlemler gerçekleştiren kraniyofasiyal cerrahlar ve diş hekimleri için de yararlı olacaktır.
