Several algorithms have been published to manage patients with mandibular condylar hyperplasia. The authors have developed and applied a comprehensive diagnosis and treatment algorithm for this condition for more than 15 years. Long-term stable occlusal and facial results of our protocol were presented through cases presentation in 2011 during the 20th ICOMS with no emphasis on the algorithm itself, which lead us to those good results. So we review the diagnosis tools and treatment options we followed in 112 patients who presented to us during the last 13 years and have a complete written technical report of having a facial asymmetry due to a mandibular condylar hyperplasia. The main author performed all this cases studies.

Objectives: Review the consistence of the authors’ algorithm for diagnosis and treatment for mandibular condylar hyperplasia.

Methods: Out of all the stored files (hard drive) of written technical reports from study cases during the last 13 years, 112 reports were found to correspond to patients whose diagnosis were facial asymmetry due to mandibular condylar hyperplasia. The records used to study those patients were digitalized storage. These records included full sets of clinical photography; imaging studies including X-rays, CT scans, CTCB’s as well as planar conventional Tec’99 cintigraphy or SPECT if used. We review the rationality to have ended up with the diagnosis of mandibular condylar hyperplasia as the cause of the facial asymmetry been studied in those patients.

Results: We found consistent grounds of the diagnostic tools being used. The technical improvements of the diagnosis tools have made easier and precise the diagnosis and clarify the treatments options. The diagnosis of condylar hyperplasia is morphologic but also metabolic activity of the affected condyle needs to be assessed. The treatment protocol needs to arrest both the malocclusion and the skeletal asymmetry.
