How is condylar hyperplasia diagnosed?
Primarily nuclear imaging techniques such as single-photon emission computed tomography (SPECT), positron emission tomography (PET), and bone scintigraphy are taken along with other data before a patient is diagnosed for Condylar Hyperplasia.
What causes condylar hyperplasia?
Condylar hyperplasia (CH) is a generic term describing conditions that cause excessive growth and enlargement of the mandibular condyle. There are many suggested etiologies of CH, including neoplasia, trauma, infection, abnormal condylar loading,1 and aberrant growth factors.
What is mandibular hyperplasia?
Condylar hyperplasia, which is also known as mandibular hyperplasia, is the presence of an enlarged mandible bone within the skull. It was first identified in 1836 by Robert Adams who associated it with the overdevelopment of mandible. The mandibular bone has two condyles.
How do you fix mandibular hyperplasia?
Treatment usually includes condylectomy during the period of active growth. If growth has stopped, orthodontics and surgical mandibular repositioning are indicated. If the height of the mandibular body is greatly increased, facial symmetry can be further improved by reducing the inferior border of the mandible.
Can condylar hyperplasia be fixed?
To correct condylar hyperplasia, it is necessary to consider its status. In the inactive status, conventional orthognathic surgery can be recommended without condylectomy. However, in the active status, active growth potential of the affected condyle should be removed.
How do you test for mandibular condyle?
Palpate directly over the joint while the patient opens and closes the mandible, and the extent of mandibular condylar movement can be assessed. Normally, condylar movement is easily felt. Have the patient close slowly, and you will feel the condyle move posteriorly against your finger.
How is condylar hyperplasia treated?
Is condylar hyperplasia genetic?
The condylar hyperplasia in this family indicates that mandibular condylar hyperplasias could be genetic in origin, possibly Y-linked or autosomal dominant. Condylar hyperplasia is an uncommon malformation of the mandible involving change in the size and morphology of the condylar neck and head.
What is the mandibular condyle?
Condyle. The most superior part of the mandible, the condyle presents an articular surface for articulation with the articular disk of the temporomandibular joint; it is convex from before backward and from side to side, and extends farther on the posterior than on the anterior surface.
Where is the mandibular symphysis?
The mandibular symphysis is the line of fusion of the lateral halves of the body of the mandible which splits inferiorly to form the mental protuberance.
What does condylar mean?
/ˈkɒn.dɪ.lər/ relating to or like a condyle (= a round part at the end of a bone that forms part of a joint): condylar cartilage. SMART Vocabulary: related words and phrases. Bone structures.
Where is the condylar process?
mandible
The condylar process, also called the condyloid process, is the process on the mandible that articulates with the disk of the TMJ.
Can bone scan SPECT detect mandibular condylar hyperplasia?
Mandibular condylar hyperplasia (CH) is a complex developmental deformity resulting in asymmetries of the hyperplastic condyle. Bone scan SPECT is a sensitive and accurate method of detecting the growth activity of this disorder. This method can be used to quantitate the radionuclide uptake differences between the left and right condyles.
Is condylar hyperplasia a bone disease?
Abstract Condylar hyperplasia (CH) is a bone disease characterized by the increased development of one mandibular condyle. It regularly presents as an active growth with facial asymmetry generally without pain. Statistically it affects more women in adolescence, although it does not discriminate by age or gender.
What are the signs and symptoms of mandibular condylar hyperplasia?
Mandibular condylar hyperplasia usually occurs unilaterally. It affects males and females equally and is usually encountered between 10-30 years of age. In most cases patients present with progressive facial asymmetry, chewing dysfunction and dental malocclusion.
How is condylar hyperplasia diagnosed with SPECT/CT?
The CT portion of SPECT/CT is useful to assess the condylar dimensions and underlying bony changes. Condylar hyperplasia (CH) is a complex developmental deformity leading to asymmetries of the hyperplastic condyle. It causes facial asymmetry and malocclusion and can be associated with pain and dysfunction.
