Introduction Progressive condylar resorption is a rare complication following orthognathic surgery. Its aetiology and pathogenesis remains unclear, although several theories have been suggested to explain it. Management modalities for progressive condylar resorption range from conservative follow-up to a second corrective orthognathic surgery. This is a report of a unilateral case of severe progressive condylar resorption that occurred in a female patient with class II skeletal deformity after bimaxillary osteotomy. The patient was followed-up for 9 years postoperatively. Case Report A 17 year old female patient referred to the Department of Oral and Maxillofacial Surgery by her orthodontist presented with mandibular hypoplasia with 5-mm overjet, high mandibular plane angle with anterior open bite, and mandibular asymmetry with deviation to the right side. Conclusion The 9-year follow-up of this case suggests that the treatment policy for future patients with PCR should be based on stabilization of the occlu-sion with splint followed by a long period of followup.
