Clinical indications as a basis for ordering extraoral imaging studies

Area of Science:

• Radiology
• Oral and Maxillofacial Radiology
• Diagnostic Imaging

Background:

• Extraoral imaging is crucial for diagnosing various head and neck pathologies.
• These pathologies include bone and mineral disorders, metabolic disorders, genetic abnormalities, and soft-tissue calcifications.
• Carotid artery calcification is one example of a soft-tissue calcification detectable via extraoral imaging.

Purpose of the Study:

• To review disorders manifesting in the head and neck region.
• To illustrate how these disorders appear on extraoral radiographs.
• To provide a framework for ordering extraoral imaging based on clinical indications.

Main Methods:

• Review of scientific literature on head and neck pathologies detectable by extraoral imaging.
• Analysis of radiographic presentations of various disorders.
• Development of a clinical indication-based approach for extraoral imaging.

Main Results:

• Extraoral radiographs can reveal a wide spectrum of pathologies affecting the head and neck.
• Specific radiographic features correlate with distinct bone, metabolic, genetic, and soft-tissue disorders.
• A systematic approach using clinical indications can optimize the diagnostic utility of extraoral imaging.

Conclusions:

• Extraoral imaging is a valuable diagnostic tool for numerous head and neck conditions.
• Understanding radiographic manifestations aids in accurate diagnosis.
• Clinical indications are essential for appropriate and effective use of extraoral imaging studies.
