Delayed mandibular reconstruction following removal of a mesenchymal chondrosarcoma. Report of a case.

An unusual case of mesenchymal chondrosarcoma is presented. Initially seen when the patient was 8 years old, the lesion was repeatedly biopsied and curetted with a diagnosis of odontogenic fibroma. In 1971 a diagnosis of osteosarcoma of the chondroblastic type was made. At that time, the patient underwent a partial mandibulectomy with immediate graft. The patient did well until 1981, when a recurrence of the lesion was noted. The microscopic diagnosis at this time was mesenchymal chondrosarcoma. The treatment of this lesion as a staged procedure with initial resection of the mandible and placement of a silicone rubber mandibular prosthesis is discussed. The second stage of the procedure was definitive mandibular reconstruction, with an allogeneic mandible as a crib for autologous particulate cancellous bone from the iliac crest. Although the prognosis of mesenchymal chondrosarcoma is usually grave, this case is unusual because of its long history of multiple procedures performed prior to the definitive treatment of the lesion 14 years after its discovery. Two-year follow-up since the definitive mandibular reconstruction shows adequate range of motion, excellent healing, and no recurrence.

Titanium implants as a temporary replacement of mandible. A report of 30 cases.

In a 5-year period, 30 titanium implants (Bowerman and Conroy 1969) were utilised for the reconstruction of mandibular defects following tumour operations. Of these, 20 implants were removed prematurely. Reasons for early removal were: 1. postoperative dehiscence of wound (5), 2. perforation through the skin or mucosa (5), 3. infection of graft bed (7), 4. breakage of the implant (1), 5. tumour recurrence (2). A total of 9 implants were retained for one or more years. The results are compared with those of Bowerman (1974). Reasons for the early loss as well as the clinical implications are discussed.

[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.

[Value of dental CT for the implant specialty in mouth, jaw and facial surgery].

The importance of dental CT in comparison to conventional OPT in implantation diagnostics is demonstrated in specific indication groups (atrophy of upper and lower jaw, patient after tumor and reconstructive surgery). The application of radiological techniques is illustrated in relation to diagnostic information quality, radiation exposure and cost effectiveness regarding clinical routine use.

Oral and maxillofacial reconstruction.

Advances in surgical technique and dental implant technology have benefitted both patients and practitioners alike. Earlier diagnosis and treatment, along with increased survival, has made it incumbent on the dental professional to be aware of what can be done for the formerly unrestorable patient. This cooperative team approach works to everyone's advantage.

Management of solid ameloblastoma of the jaws with liquid nitrogen spray cryosurgery.

OBJECTIVE: This study evaluated the results of the use of curettage followed by liquid nitrogen spray cryosurgery in a number of solid or multicystic ameloblastomas of the jaws and the postoperative complications related to this treatment modality. STUDY DESIGN: Thirty-six patients with solid ameloblastoma of the jaws were treated with curettage followed by cryosurgery. The cryotherapy consisted of hand instrumented curettage of the bone lesion followed by three freezing cycles, of 1 minute each, of the remaining bone cavity with liquid nitrogen spray. Postoperative complications were evaluated clinically and radiographically. RESULTS: Local recurrence occurred in 11 (30.6%) patients. Excepting local recurrence, postoperative complications were frequent but not severe: wound dehiscence (5.5%), paraesthesia (5.5%), infection (5.5%), and pathologic fracture (11.1%). CONCLUSION: Management of solid or multicystic ameloblastomas of the jaws with curettage followed by cryosurgery may decrease the local recurrence rate and also to reduce the initial indication of resection with continuity defect.

Cementifying fibroma: resection of recurrent mandibular lesion with microsurgical preservation of inferior alveolar nerve and immediate reconstruction.

Cementifying fibroma is a benign fibro-osseous lesion that may occur in either the mandible or the maxilla, with a predilection for the mandible. In the patient described, a recurrent mandibular cementifying fibroma was successfully resected, with microsurgical preservation of the inferior alveolar nerve and immediate reconstruction via an autogenous iliac bone graft.

[Myxoma of the mandible. A case report].

Maxillo-mandibular myxomas are rare lesions and their pathogeny remains unclear. The poor clinical picture and the absence of pain makes the diagnosis difficult. Because of the long lasting course, the tumor is usually large at the time of diagnosis. Although this tumor is benign, the local aggression and the high rate of recurrence dictate a radical treatment.

[Anatomo-functional consequences of the radical surgery of the cervico-cephalic region in oncologic patients].

The role of surgery in head and neck cancer treatment is now well established, as it appears the most effective approach to such patients, while other therapies (i.e. chemotherapy, radiotherapy) can be of some help as second choice procedures. Surgery demonstrates however its own pitfalls, as it can often cause secondary anatomo-functional defects. The main problems appear to be related to the impossibility of physiological feeding following composite resection for oral cancer. An immediate reconstruction by transposition of myocutaneous flaps is of the utmost importance, as it reestablishes the preoperative condition lessening hospitalization time and postoperative disabilities. Neurological lesions, an unfrequent major complication of cervical lymphadenectomy, can cover a wide range of seriousness, from hardly detectable sensorial deficits to the impossibility of spontaneous ventilation. In this paper the Authors, on the basis of their experience, describe the measures to be taken in order to avoid secondary lesions (or to minimize their effects) in head and neck cancer surgery.
