Boering’s arthrosis is a rare disorder of the temporomandibular joints that usually occurs in the second decade and seldom after age 20. It was first described by G. Boering in 1966. It is more common in females and can be unilateral or bilateral. The disease results in resorption of the condyle with elongation of the articular surface resulting in the characteristics toadstool appearance observed on panoramic images. Condylar changes are often accompanied by anterior displacement of the disc and remodeling of the glenoid fossa. Facial asymmetry is almost always present. We present a case of a 9-year-old female with Boering’s arthrosis. She presented with facial asymmetry and bite abnormality but did not report symptoms typically associated with temporomandibular disorders.
