Abstract:
Arthrogryposis multiplex congenita (AMC) is a rare congenital syndrome consisting of two or more joint contractures in different parts of the body. Otolaryngological abnormalities have been previously described in a significant proportion of cases. However, to date, the only frequent otologic deformity recorded in the published literature has been low-set ears. We present a case with a combination of AMC and a bilateral conductive hearing loss due to an unusual middle ear deformity. To our knowledge, no such case has been previously reported.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
