Detection of condylar hyperplasia.. Photon Emission

Detection of condylar hyperplasia:

  • A- OPG.
  • B- CT scan.
  • C- Photon Emission***
SPECT (single photon emission computed tomography) has been used with quantitative assessments of one mandibular condyle to clivus or lumbar spine, but we have compared one condyle with the other, which is more sensitive and accurate in detecting abnormal activity.

Is Hemimandibular hyperplasia the same as condylar hyperplasia?

Condylar hyperplasia can been classified as hemimandibular elongation, in which the mandible displaces horizontally toward the unaffected side; hemimandibular hyperplasia, in which there is three-dimensional enlargement of the mandible through the midline; or a combination of the two.

What is the clinical feature of condylar hyperplasia?

In 66% of the patients, the main complaint was progressive facial asymmetry; and in the remainder, the main complaint was pain, dysfunction, or both. Transverse asymmetry predominated (52%), and vertical or combined asymmetry occurred in 31% and 16% of patients, respectively; asymmetry type was independent of age.

What is the validity of Spect CT in diagnosis of condylar hyperplasia?

The diagnostic performance of SPECT/CT in diagnosis of CH was demonstrated as a sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 85.7%, 100%, 100%, 75%, and 90% respectively.

How is condylar hyperplasia diagnosed?

Primarily nuclear imaging techniques like single-photon emission computed tomography (SPECT), positron emission tomography (PET) and bone scintigraphy are collected along with other data prior to diagnosing a patient with Condylar Hyperplasia.
