Chief Complaint: “My neck and throat have been hurting me. I feel like something is always stuck in my throat, and it's hard to turn my head.”

This imaging modality is most appropriate for screening the cause of the chief complaint

PANO. 

The chief complaint and the current findings point to Eagle’s syndrome, a condition caused by the elongation of the styloid process and/or calcification of the stylohyoid ligament. Symptoms include pain during swallowing and head movement, shooting pains from the throat to the jaw, ringing in the ears, or a feeling that something is stuck in the throat.

Air space. 

The radiolucent area on the right ramus is due to the palatoglossal air space. This radiolucency is caused when the patient’s tongue does not touch the palate during radiographic exposure.

Cementoblastoma


  • A cementoblastoma is directly attached to a tooth, typically a molar or premolar, and no lamina dura is present.

The name if this radiolucent area is....

The lateral fossa

The lateral fossa is a depression on the labial surface of the maxilla around the root of the lateral incisor. In periapical radiographs, this appears as a diffuse radiolucency located both anterior and posterior to the lateral incisor root.

The triangle is displaying ...

Stafne bone cyst, or Stafne defect: 

Represents a depression of the mandible and is thought to result from remodeling of the bone adjacent to salivary tissues. Radiographically, it is a unilateral, oval-shaped, radiolucent defect in the posterior region of the mandible below the inferior alveolar canal. Most other odontogenic cysts appear above the inferior alveolar nerve canal.


It is considered a pseudocyst because it lacks an epithelial lining. It is a normal anatomical variant, usually asymptomatic, and requires no treatment.

Radiological appearances if this neoplasm manifests as mixed radiopaque and radiolucent lesions with periodontal ligament widening. Lesions commonly include radiopaque, “starburst” proliferation of abnormal bone.

Osteosarcoma is a malignant bone neoplasm, most often characterized radiographically by radiopaque, “sunburst” lesions.

CC: I fell and broke some teeth.

Presentation: 

Large fractures on teeth 29 and 30 with pulpal exposures, bleeding from sulci between 29 and 30

Slight leftward jaw deviation upon opening, lateral open bite on the right. 

Which imaging modality is the most appropriate?


A panoramic image is the best option to evaluate the entire mandible.

Findings of jaw deviation and malocclusion (in this case, an open bite) suggest that there may be a mandibular fracture.

External resorption; the impacted tooth 17 is exerting continuous pressure on the root of the adjacent second molar, which can lead to external resorption.

This benign odontogenic tumor typically affects those over the age of 20. Common characteristics include:

  • Locally aggressive growth pattern
  • Rapid cortical expansion
  • Tooth displacement and root resorption
  • High incidence of recurrence following treatment

Ameloblastoma; a well-defined, multilocular, radiolucent lesion with soap bubble septa that can extend through large portions of the posterior mandible.
