Aggressive idiopathic condylar reabsorption after orthognathic surgery: A complex Imaging diagnosis

Abstract

Idiopathic condylar resorption (ICR) is a pathological condition of unknown origin that affects the temporomandibular joint (TMJ) and can lead to malocclusion, facial asymmetry, TMJ dysfunction and orofacial pain. Imaging examinations are essential for diagnosis and planning of future treatment. To diagnose ICR, it will always be necessary to perform imaging tests and associate them with predisposing risk factors to understand the level of bone remodeling and mechanical trauma performed to propose the best type of treatment. The objective of this study was to elucidate the clinical case of a patient who underwent orthodontics and orthognathic surgery and after 2 years, occlusion recurrence was diagnosed with a severe and active ICR. In addition, it demonstrates the importance of requesting postoperative imaging examinations and clinical radiographic monitoring.
