HEMIMANDIBULAR HYPERPLASIA PDF

Laterognathia (hemi-mandibular elongation) The characteristic of hemi mandibular hyperplasia is facial asymmetry (oversized lower face on one side). Hemimandibular hyperplasia (HH) is a developmental asymmetry characterized by three-dimensional enla. Hemimandibular hyperplasia is a developmental asymmetry characterized by three-dimensional enlargement of half of the mandible.6 The hyperplastic side.

Condylar hyperplasia mandibular hyperplasia is over-enlargement of the mandible bone in the skull. In humans, mandibular bone has two condyles which are known as growth centers of the mandible. The most common form of condylar hyperplasia is unilateral condylar hyperplasia where one condyle overgrows the other condyle leading to facial asymmetry.

Hugo Obwegeser et al.

These anomalies can be clinically present in a pure form or in combination. Condylar hyperplasia has an unknown cause. Several theories exist in literature which related to the cause of condylar hyperplasia. One theory states that an event of a trauma leading to increase in number of repair mechanism and hormones in that area may lead to increase in growth of mandible on that side.

Diagnosis of asymmetry can be done through many different methods. PA cephalometry, panoramic radiograph, and nuclear imaging are some of the techniques that can be used for diagnosis. Hugo Obwegesr and Makek classified condylar hyperplasia into three categories, listed in the table below.

Many treatment options exist for this type of condition. Orthognathic surgery can be performed once the active condylar growth has finished in some cases.

The point of this surgery to wait as long as the condyle is growing and only do surgery when the condyle stops growing, so the chances of any worsening hyperplzsia facial asymmetry lessens.

This option, however, does include a person living with heimandibular facial asymmetry features all the way up until 18 to 19 years of age.

A procedure called condylectomy can also be done which involves removing part of the growing condyle to arrest any active growth. From Wikipedia, the free encyclopedia. International Journal of Clinical and Experimental Medicine.
