Objectives:
Timely and accurate diagnosis of nasal bone fractures (NBFs) is crucial for preserving the cosmetic and functional aspects of the nose. This study aims to identify factors influencing radiographic and computed tomography (CT) diagnosis of NBF in patients with nasal trauma.
Methods:
Two hundred six patients with acute nasal trauma underwent both conventional radiography and facial bone CT. An experienced otorhinolaryngologist independently interpreted images. Results were categorized into "Concordance" or "Discrepancy" groups, with demographic and clinical data compared.
Results:
The study classified 167 patients into "Concordance" and 39 into "Discrepancy" groups based on radiography and CT interpretations. The "discrepancy group" showed higher rates of previous nasal bone fractures (P=0.044), rhinoplasty history (P=0.044), and concomitant facial bone fractures (P=0.001). Adjusted odds ratios revealed significant associations between discrepancies and a history of nasal bone fracture (OR=5.197, 95% CI 1.165-23.171), rhinoplasty (OR=6.114, 95% CI 1.393-26.847), and concomitant facial bone fractures (OR=3.765, 95% CI 1.663-8.523).
Conclusion:
This study highlights the impact of facial trauma, including rhinoplasty, on the radiological diagnosis of NBF. Consequently, in the presence of signs of concurrent facial trauma, previous nasal trauma, or rhinoplasty history, a prompt CT scan and comprehensive evaluation are recommended for accurate diagnosis and timely treatment, ultimately improving the patient's prognosis.

01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
