Comparison Between The Sensitivity Of Ultrasoundand Conventional X-Rays In Diagnosing Nasal Bone Fracture
A cross-sectional study was conducted in AL- Sadir medical city in AL Najaf-Iraq,Â during the period between July 2011 to March 2012, 35 patients aged 1 to 45 years with nasal bone fracture who underwent physical examination Aim: To evaluate the sensitivity of ultrasoundÂ in the diagnosis of nasal bone fracture in comparison with conventionalÂ X ray sensitivity.
Patient & method: these patients were examined by conventional lateral nasal bone radiography followed by sonography without knowing the result of x-ray report and physical examination.
Results: In this study a 35 patients who had nasal bone fracture according toÂ physical examination were investigated by sonography and radiography.Of these patients, 30 were men and 5 were women,Â with mean age of patients was 18.63 years. The current study revealed an x ray sensitivity approachingÂ 60% , specificity was 86.7%. respectively. While Â the results showed that ultrasonography sensitivity was 80% , specificity was 6.7%.compared with clinical examination. The present study showed comparison of both tests that ultrasonography sensitivity was 80% , specificity was 6.7% ,while x-ray was 60%, 86.7% .Also the results showed patients gender distribution of the nasal bone fracture withÂ female and male percentage of 14.3% and 85.7% respectively. The results showed depending on trauma type domestic , RTA, and direct, the percentage rate was 34.3%, 11.4% and 54.3 % respectively. Also the results showed that frontal trauma associated with nasal bone fracture is 62.9% Â while a lateral trauma associated with nasal bone fracture is 37.1% .
Â Conclusions : Ultrasound is more sensitive test than x-rays in the diagnosis of nasal bonefracture and males are more exposed to nasal bone fracture than femalesÂ with direct trauma is the predominant cause for nasal bone fracture.
Recommendation:Usingultrasound to confirm nasal bone fracture after clinicalÂ examination especially in children and pregnancy because it safer,Â cheaper , more sensitive and real time scan& to expanding the study to include follow up of patient after treatment .
