ABSTRACT

Three total temporomandibular joint (TMJ) replacement surgeries were performed on two patients with TMJ ankylosis using W. Lorenz system. The first surgery was performed on a female patient with osseous ankylosis who had no mandibular movement since she was 18 months old. The second surgery was on a patient with fibrous ankylosis who had an interincisive opening distance of 12 mm. Her condition was the result of a three year old subcondylar fracture which didn’t receive any treatment. The first patient had total replacement of both TMJ’s, while the other just one TMJ. The follow up until today has been of eight months with an interincisive opening of 29 mm in the first patient and 34 mm in the other. There has not been any mandibular deviation during opening, nor postoperative pain in both cases. Facial nerve affection was not permanent in both patients. For all of this, we can conclude that total TMJ replacement is an effective treatment with stable results in patients with TMJ ankylosis.
