The etiology and pathogenesis of progressive condylar resorption/idiopathic condylar resorption(PCR/ICR) remain unclear to date. The clinical manifestations of this condition are morphological changes, reduced condylar volume, and decreased ramus height. Serious PCR/ICR can lead to mandibular retrognathism. Surgery as an effective therapy for maxillofacial deformities can improve functionality and maxillofacial aesthetics. This review focuses on the orthognathic surgery of PCR at present.
