Summary

Conventional Caldwell's and Waters' views offer reliable initial diagnosis for orbital wall fractures. While CT scans provide superior detail, plain films remain a valuable tool for detecting orbital fractures.

Area of Science:

  • Radiology
  • Ophthalmology
  • Trauma Surgery

Background:

  • Orbital wall fractures are common injuries.
  • Accurate initial diagnosis is crucial for appropriate management.
  • Conventional radiography is often the first imaging modality used.

Purpose of the Study:

  • To evaluate the diagnostic efficacy of conventional plain films (Caldwell's and Waters' views) in identifying orbital wall fractures.
  • To compare the diagnostic accuracy of plain films with computed tomography (CT) scans for orbital fractures.

Main Methods:

  • A clinical study comparing plain film radiography and coronal CT scans.
  • Analysis of diagnostic performance for orbital floor, medial orbital wall, and ethmoid-maxillary plate fractures.
  • Assessment of sensitivity, specificity, and false-negative rates for each imaging modality.

Main Results:

  • Conventional views showed good reliability for detecting orbital fractures: orbital floor (78% anterior, 73% posterior), medial orbital wall (71% anterior, 72% posterior), and ethmoid-maxillary plate (64%).
  • False-negative rates for plain films were observed, particularly for the medial orbital wall (up to 29%) and ethmoid-maxillary plate (21%).
  • Results align with previous literature on the diagnostic utility of conventional radiography for orbital fractures.

Conclusions:

  • Conventional Caldwell's and Waters' views provide a fairly reliable initial diagnosis of orbital wall fractures.
  • While CT scans offer more detailed imaging, plain films remain a valuable and accessible tool for initial fracture detection.
  • Understanding the limitations and false-negative rates of plain films is important for clinical interpretation.
