[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.

Findings of mandibular movement and the position of the mandibular condyles during maximal mouth opening.

An investigation with respect to position of the mandibular condyles in relation to maximal vertical mouth opening was undertaken. For this purpose, 51 subjects of different nationalities were examined. None of the 51 persons had a TMJ disorder. The mobility of the mandible in different directions was clinically measured. With the use of two different reference lines (Methods A and B), the amount of the movement of the condyle from closed to maximal mouth opening position was measured in the sagittal plane on lateral tomograms. All of the measurements were recorded, and the means, SD, and range of variation were calculated. Statistical analysis was subsequently performed. The clinical results are comparable to those of other previous clinical studies. As seen in the lateral tomograms, the condyle in 41 out of 51 subjects moved beyond the articular eminence during maximal mouth opening. It was occasionally situated higher than the eminence. In only ten subjects, the condyle reached only the top of the articular eminence during maximal mouth opening. A moderate degree of dependency and correlation was found between maximal vertical movement of the mandible and the amount of movement of the right and left condyles from closed to maximal open position of the mouth, as seen in tomograms. None of our subjects had any sign of luxation despite the position of the condyle beyond the articular eminence with maximal mouth opening. Therefore, the diagnosis of condylar luxation cannot be established by radiologic investigation alone.

Results after mandibular ridge augmentation with laminated split ribs, pedicled anterior bone lid and simultaneous sulcoplasties. Preliminary report.

The early results of a combined method of augmentation for extreme mandibular atrophy (Farmand, 1986) are evaluated in 40 patients over a period of up to 12-15 months after operation. The method combines the advantages of the classic augmentation procedure with laminated split ribs (Obwegeser, 1967, 1977) with those of the sandwich technique (Schettler, 1976). In cases with mucosa of good quality and quantity a simultaneous lingual and vestibular sulcoplasty is performed, thus giving the patient in a single-stage operation, conditions for adaptation of well-fitting dentures. It could be shown, that during the investigation time the mean resorption rate was 7-16% of the total anterior mandibular height. In the lateral parts, the resorption is in most cases less than one third of the transplant. 10 of 15 patients without simultaneous sulcoplasties needed a secondary soft tissue procedure after 9 months. 11 of 25 patients with simultaneous sulcoplasties needed the secondary operation. There is only one patient with a residual hypoaesthesia of the mandibular nerve. Local complications were seen in 22 cases and these were treated adequately.

Horse-shoe sandwich osteotomy of the edentulous maxilla as a preprosthetic procedure.

A preprosthetic procedure for treatment of severe atrophy of the maxilla is reported. By means of the horse-shoe sandwich osteotomy of the edentulous maxilla with interposition of iliac crest or ribs in combination with a modified submucous vestibuloplasty there is the possibility of increasing the vestibular and palatal height and improving the mucosal contour in one surgical session. The method, which is described in details, avoids the disadvantages of the earlier operation methods of direct osseous augmentation and the Le Fort-I-osteotomy of the edentulous maxilla. The satisfactory results of 15 operated cases in the observation period of 3 to 15 months are reported. There is only little bone resorption. The horse-shoe sandwich osteotomy might therefore be the method of choice in cases of extreme atrophy of the maxilla.
