[Clinical and anatomopathologic classification of fractures of the orbit].

One hundred forty-four orbital fractures treated between 1982 and 1987 were examined with special attention to the specific anatomic architecture and biomechanical aspects of the craniofacial skeleton. The following parameters were examined: lesion mechanism, the bony lesion observed at surgery, clinical signs of fracture and morphological, functional and esthetic sequellae. All operated patients had undergone an ophthalmological examination prior to surgery, with special attention on binocular vision and ocular motility. Fractures were classified into pathological groups according to the parameters studied. For each group, clinical signs and accompanying sequellae were described. Seven clinical and pathological groups of orbital fractures were described, each with its specific mechanism of trauma, bony lesions, clinical signs, sequellae and appropriate treatment.

[Results of treatment of upper gingiva and palate carcinomas].

From 1981 to 1986 in the Department of Maxillofacial Surgery, Institute of Stomatology, Medical Academy in Warsaw 85 patients were treated for carcinoma of the upper gingiva and palate. The follow-up of the patients after treatment was from 3 to 7 years. The obtained results of the treatment were analysed depending on the degree of differentiation of neoplasms and their biological aggressiveness and the therapeutic method used. It was found that the results of the treatment of upper gingiva carcinoma were not satisfactory. The best results were obtained using surgical treatment followed by radiotherapy. A positive result of the treatment without symptoms of recurrence was achieved in 21 cases (24.7%).

[Comparison of the effectiveness of conventional methods of radiological examinations and computed tomography in the diagnosis of lower gingiva tumours].

In 22 patients aged 34 to 87 years treated in the Department of Maxillofacial Surgery, Institute of Stomatology, Medical Academy in Warsaw for malignant tumours of the lower gingiva the usefulness was assessed of the conventional radiological methods and computed tomography for the evaluation of malignant infiltrations. Computed tomography was found to be an auxiliary radiological method determining best the morphology and syntopy of malignant neoplasms of the lower gingiva infiltrating the soft tissues of the oral floor.

[The effectiveness of selected surgical methods in the treatment of zygomatico-maxillary fractures].

In a period of 3 years, from 1984 to 1986 in the Department of Maxillofacial Surgery, Institute of Stomatology, Medical Academy in Warsaw 442 patients were treated for zygomatico-maxillary fractures, in 101 cases the treatment was conservative, and 341 were treated surgically by various operative methods. The aim of the study was assessment of late effectiveness of the surgical methods used most frequently in zygomatico-maxillary fractures with reposition of skeletal fragments either with one-pronged hook introduced percutaneously or from the side of the lumen of the maxillary sinus. The criterion of effectiveness of both methods was accepted to be functional assessment of the visual system and the stomatognathic system, and the condition of sensory function in the area of innervation by the suborbital nerve. Control examinations were done 2-5 years after operations confirming the both methods were successful in 90% of the treated group. A more detailed analysis of these methods is not possible since the qualification for these operations differentiated essentially both groups of patients.

[Late results of treatment of maxillary fractures].

In the period of 3 years, from 1984 to 1986 in the Department of Maxillofacial Surgery, Institute of Stomatology, Medical Academy in Warsaw 230 patients were treated for maxillary fractures. Late results of this treatment were assessed in 102 patients coming for control examinations in 1988. In the assessment of the therapeutic results the following features were considered: facial symmetry, proportions of three facial segments, functions of the visual system and stomatognathic system, nasal patency, and sensory disturbances in the area innervated by the infraorbital nerves. On the basis of this late assessment of the results of treatment of these fractures it was found that the definite morphological-functional and aesthetic results were unsatisfactory in cases of Le Fort III and II type maxillary fractures. This points out that the therapeutic methods used as yet are not sufficiently satisfactory and other methods should be evolved.

[Analysis of surgical-orthopaedic treatment of mandibular fractures in patients treated in the period 1984-1986].

During 3 years 1246 patients were treated for mandibular fractures, 828 of them were treated by conservative-orthopaedic methods while in 418 patients the displaced mandibular fragments were reduced and fixed surgically using various methods. The purpose of the assessment was a group of 319 patients in whom the fragments were reduced and fixed with ossous sutures. A good result of treatment was achieved after this operation in 291 cases (91.2%). In 28 patients (8.8%) postoperative complications developed requiring reoperation.

[Late results of treatment of mandibular fractures].

In a group of 1246 patients treated in the Department of Maxillofacial Surgery-Institute of Stomatology, Medical Academy in Warsaw, in a period of 3 years (1984-1986) late results of treatment of mandibular fractures were assessed. In the assessment the range of mandible abduction, function of temporomandibular joints, occlusal abnormalities, the sensory function in the area innervated by the mental nerves and the condition of posttraumatic scars changing the morphology and aesthetic appearance of the face were considered. Limitation of mandibular abduction after treatment was found in 39 cases. Functional disturbances of temporomandibular joints developed in 58 cases, and various occlusal complications were found in 130 out of 1246 patients. In 56 patients various sensory loss was noted in the innervation area of the mental nerves. Posttraumatic scars in 89 patients affected in various degree facial morphology and aesthetic appearance.

[Craniopantograph--an instrument for determination of orbit shape].

The authors describe the structure of principles of function of a measuring-recording instruments, so called craniopantograph. The instrument of own design serves for examination of the spatial variability of the orbit. The obtained measurements of the internal shape of the orbit can be processed later by microcomputer technique. For construction of craniopantograph the principles of function of two typical instruments--craniometer and pantograph were used.
