Panoramic radiographic imaging is a technique that requires precision, and errors during patient preparation and positioning can significantly impact the quality of the resulting image. Let’s explore some common errors:
Chin Positioning Errors:
Chin Tipped Too High: When the patient’s chin is positioned too high, it can lead to an elongated appearance of the mandible in the panoramic image.
Chin Tipped Too Low: Conversely, if the chin is tipped too low, the mandible may appear foreshortened.
Chin Positioned Too Far Forward or Back: Incorrect chin placement affects the alignment of the maxilla and mandible, leading to distortion in the image.
Head Positioning Errors:
Head Positioned Too Far Forward: This can cause overlapping of the cervical spine and result in unclear visualization of the upper cervical vertebrae.
Head Turned Right or Left: Lateral head rotation can lead to asymmetry and distortion of anatomical structures.
Head Tilted Down: Excessive downward tilt can obscure the maxillary sinuses and impact overall image quality.
Head Positioned Too Far Backward: When the head is too far back, the mandibular condyles may not be captured adequately.
Other Errors:
Tongue Not on Palate: The patient’s tongue should rest on the palate during exposure. Failure to do so can result in artifacts or unclear structures.
Spine Slumped: Poor posture can affect the alignment of the cervical spine and lead to suboptimal images.
No Side Identification: Properly identifying the patient’s left and right sides is crucial for accurate diagnosis and treatment planning.
