Ideopathic condylar resorption is most often associated with orthognathic surgery but it may also occur in relation to conditions such as rheumatoid arthritis, systemic lupus erythematosis or be the result of treatment with steroids, trauma or even orthodontic treatment.
The figures, as presented in the somewhat sparse literature, however, are alarming in that fairly high percentages are reported, particularly associated with some rather specific procedures, including anterior open bite associated with mandibular hypoplasia. Signs and symptoms that are pointing towards the development of condylar resorption post surgery will be highlighted and the natural course of events described. Unfortunately, no known measures exist, at the present day, to stop the process.
The existing literature on the aetiology and presentation of this condition will be presented along with some general guidelines for treatment.
