Recurrence of a solitary bone cyst of the mandibular condyle in a bone graft. A case report.

The recurrence of a solitary bone cyst of the mandibular condyle in a costochondral bone graft is reported. A solitary bone cyst of the right condylar head and neck of a 10-year-old boy was treated by total resection and immediate reconstruction with a costochondral bone graft. Two years after the first operation, a recurrence of the solitary bone cyst within the bone graft was noted. An open treatment was performed. A review of the literature on solitary bone cysts and recurrences of solitary bone cysts shows that the case reported is unique. Possible reasons for the recurrence are discussed.

The treatment of the fractured edentulous maxilla.

The results of a follow-up of 13 out of 21 patients treated for fractures of the edentulous maxilla are presented. They were treated alternatively with craniofacial suspension wiring and with miniplate osteosynthesis. Better results are achieved by miniplate osteosynthesis. Depending on the general condition of the patient, a treatment scheme can be recommended.

[Pathological changes in face and skull in acromegaly].

31 patients (mean age 52.7 years) suffering from persistent symptoms of a growth hormone producing pituitary adenoma underwent both clinical and roentgenological examinations. The results of standardized x-ray analysis of the viscero- and neurocranium were compared with those of a group of 25 healthy subjects (mean age 42.1 years): Although several remarkable changes were observed, statistically significant changes of the facial skeleton could be found only in the lower jaw. The main contribution to its elongation was given by the chin prominence and the condyle. The findings in the neurocranium could be divided in symptoms of first and symptoms of second choice. With the help of these parameters, a score was established to facilitate interpretation of early signs of acromegaly in lateral skull radiographs. Two clinical symptoms found in our patient sample have not been mentioned before in literature about acromegaly: the so-called "hanging columella" and marked changes in diameter of the canalis mandibularis.

[The value of 3-dimensional plates in maxillofacial surgery].

Plate osteosynthesis for bone fragment stabilisation in maxillo-facial surgery is a universal method whose advantages and drawbacks are now well documented. A new system of plates made out of titanium (3-D plates) is presented. The geometry of the plate assures a good stability in the three dimensions of the space. Easy use, good resistance against torque forces, compact form of the plate are some of the advantages. Various clinical cases are presented.

Typical changes in the viscerocranium in acromegaly.

31 patients (mean age 52.7 years) suffering from persistent symptoms of a growth hormone-producing pituitary adenoma underwent both clinical and radiological examination at least one year after transnasal extirpation of the tumour. The results of standardized X-ray analysis of the viscerocranium were compared with a group of 21 healthy subjects (mean age 42.1 years): Although several remarkable changes of the facial skeleton were observed, statistically significant changes could be found in the lower jaw only. The ascending ramus as well as the mandibular body were found to be elongated. The main contribution to the elongation was made by the chin prominence and the condyle. Two different growth patterns of the mandible could be determined; neither of them was pathognomonic for acromegaly. Due to overgrowth of the septal cartilage in 7 patients we found a so-called "hanging columella". In 16 patients the mandibular canal was widened and showed marked deviations in its diameter or a funnel-shaped mandibular foramen.

[Interstitial and percutaneous radiotherapy after limited surgery in carcinoma of the oral cavity].

From 1.1. 1986 to 31.12. 1990 50 patients with epidermoid carcinoma of the floor of the mouth and the mobile tongue (stage T1 18, stage T2 20, stage T3 eight and stage T4 four patients) were treated by surgery, 192-iridium implantation using the plastic tube technique and percutaneous irradiation. Surgery was performed as enoral resection (35 patients) or en bloc tumour resection with part of the mandible and flap reconstruction (15 patients). Interstitial therapy was considered as a boost to primary tumour region, the dose given ranged between 16 and 33 Gy. 50 to 60 Gy were applied with external beam radiotherapy. Management of the neck consisted of elective or radical neck dissection followed by external beam radiotherapy (50 to 60 Gy). At 2/1991 median follow-up was 17 (three to 53) months. 35 patients are alive and tumour-free, one patient lives with tumour. 14 patients died, eight patients tumour-related, four patients of intercurrent disease and two patients because of a second primary. Primary local control was 18/18 patients for stage T1, 19/20 patients for stage T2, 7/8 patients T3, 3/4 patients for stage T4. Three patients suffered from nodal recurrences, four patients from distant metastases. Complication rate was acceptable. Soft tissue necrosis occurred in 4/18 patients (T1); 5/20 patients (T2); 3/8 patients (T3) and 1/4 patients (T4). Three patients developed osteoradionecrosis. Our results show that combined modality treatment for tumours of the oral cavity yields high local control with acceptable complication rate.

Facial growth after treatment of unilateral temporomandibular joint ankylosis in childhood without growth centre transplantation. A serial cephalomorphometric study.

Our aim was to study the influence of early surgical treatment of temporomandibular joint ankylosis on further facial growth and development. At the Department of Maxillo-Facial Surgery, Zurich, 11 children with a unilateral TMJ-ankylosis met the criteria of a maximal preoperative interincisal mouth opening of 15 mm, of a minimal long-term postoperative interincisal mouth opening of 30 mm, and of excellent documentation. 30 anatomical landmarks were defined on the copies of the follow-up cephalograms using the structure-superimposition technique. The points were perforated and digitized. Analysis and graphic-plotting were followed by computer. The hypothesis that mandibular growth continues once the ankylosis was successfully treated (without transplantation of a growth centre) and mandibular function definitely restored, was confirmed. The treatment does normalize the growth rate, but it seems that abnormal growth patterns cannot be influenced by it. As a consequence, the surgical release of the ankylosis should be performed as early as possible.

[Prosthetic management following submucous vestibuloplasty].

20 patients who had been treated with a submucous maxillary vestibuloplasty were examined 1 to 3 years postoperatively. The postoperative result of surgery and the prosthetic conditions were evaluated according to fixed criteria by a maxillofacial surgeon and a prosthodontist. From the prosthetic point of view, the postoperative result was good in 15 cases, sufficient in 2 cases and, due to false diagnoses, unacceptable in 3 cases. 13 patients were completely satisfied by the postoperatively inserted dentures, 6 were only partially satisfied and 1 person was dissatisfied. Although 13 patients were satisfied, only 10 dentures were without significant defects.
