[Bone regeneration over plastic implants after mandibular resection breaking the continuity].

In young patients, bone regeneration may start from the region of the temporo-mandibular joint and from the peripheral mandibular stump in cases of continuity defects of the mandible. A resin graft implanted for soft tissue reconstruction is collar-like surrounded by bone which is developing into a functionally and anatomically full regenerate over many years, in correspondence to periosteal and desmal growth stimuli. In adults, regeneration is minimal.

[Experience with titanium mesh as a temporary foreign material implant for the reconstruction of mandibular defects].

Restoration of a loadable mandible after extensive resections, defects or comminuted fractures, serious osteomyelitis and pseudarthrosis will be successful only if sufficiently stable fixation of the fragments and immobilization beyond the physiological period of bone healing are guaranteed. By means of various types of plates and extroral appliances for osteosynthesis the conventional methods have been improved, but failures and complications are still frequent. The treatment itself is a great strain for the patient. The titanium mesh implant system developed by Ph. Boyne and his group for reconstruction in mandibular defects means, in our opinion, an important therapeutical step forward. Its technical advantages and our own clinical experience advocate application of this system.

Cobalt radiation to prevent reankylosis after repeated surgical failures: report of case.

This is the first reported case of the use of cobalt 60 radiation for the prevention of recurrent TMJ ankylosis after repeated surgical treatment had failed. Although radiation therapy is not usually indicated for benign conditions, 2,000 rads can be used safely to treat this crippling condition. Although no conclusions can be drawn from a single case, successful treatment of this patient is indicated by a 3 1/2-year follow-up.

Arthroplasty of the temporomandibular joint with use of a vitallium condyle prosthesis: report of three cases.

We have devised a Vitallium intramedullary prosthesis to replace the deformed arthritic condyle in cases that require bilateral condylectomy or in rare long-term failures of a single condylectomy. Experience has led to modification of this prosthesis. Recently a rectangular stem that prevents rotation of the prosthesis in the condylar stub has been added (Fig 11). In bilateral condylectomies, replacement of only one side by the Vitallium condylar prosthesis is adequate, because it stabilizes the mandible by maintaining its original fulcrum in the temporomandibular joint. Three cases of replacement with the Vitallium condyle prosthesis are reported, with follow-up studies of two to three years postoperatively. The results to date have been gratifying.

[Therapeutic principles in angioma of the mandible: applications in relation to a clinical observation (author's transl)].

When confronted with a case of angioma of the mandible, treatment should be directed towards two main areas:--to stop blood loss. Ligature of the external carotid can be life-saving, but it does not prevent the formation of nearby anastomotic vessels which refill, more or less rapidly, the external carotid axis. Ligature make embolization impossible by femoral way. A by-pass operation to improve permeability is also dangerous if not impossible. Ligature should be reserved only for those cases in which there is an immediate threat to life. On the contrary, embolization is necessary before surgery. --to treat the angioma. As radiotherapy is not effective or is dangerous, surgical treatment is necessary; either by a conservative operation or by radical resection. All these facts are illustrated dramatically by the case reported.
