Finite element method for analysis of stresses arising in the skull after external loading in cranio-orbital fractures.

Background And Purpose: The craniofacial skeleton remains not fully recognised as far as its mechanical resistance properties are concerned. Heretofore, the only available information on the mechanism of cranial bone fractures came from clinical observations, since the clinical evaluation in a living individual is practically impossible. It seems crucial to implement computer methods of virtual research into clinical practice.

A peculiar blow-out fracture of the inferior orbital wall complicated by extensive subcutaneous emphysema: A case report and review of the literature.

Background: Blow-out fracture of the orbit is a common injury. However, not many cases are associated with massive subcutaneous emphysema. Even fewer cases are caused by minor trauma or are associated with barotrauma to the orbit due to sneezing, coughing, or vomiting.

Salivary gland calculi - contemporary methods of imaging.

The aim of this article was to present current diagnostic imaging modalities carried out in patients suspected with salivary stones on the basis of own material and review of literature.

Borrelia burgdorferi--a potentially aetiological factor in TMJ disorders? Preliminary report.

Introduction: The available literature does not report on infectious factors potentially triggering intra-articular pathology or dysfunction manifest as temporomandibular (TMJ) disorders.

Aim Of The Study: To establish the presence of Borrelia burgdorferi spirochaetes in the histopathological material obtained from the intra-articular space by arthroscopy from patients with advanced TMJ disorders.

Subjects And Methods: The histopathological material was obtained intra-articularly from 31 patients by means of arthroscopy; apart from routine H+E staining, the material was additionally examined for the presence of micro-organisms (spirochaetes) by the Warthin-Starry method.

Diagnostic difficulties and treatment of non-Hodgkin lymphoma of the orbit.

Background: There are problems connected with the diagnosis of non-Hodgkin lymphomas of the orbit, before deciding on the correct treatment.

Material And Methods: Six out of 22 patients with a tumour of the orbit were treated between 1995 and 2004 for orbital non-Hodgkin lymphomas (NHL). Morphological-functional and aesthetic complications regarding the eyes, the delay between onset and diagnosing the disease and concomitant conditions were evaluated.

Treatment of osteomas located between the anterior cranial base and the face.

Objective: Osteomas located on the border between the anterior cranial base and the facial region are benign, often asymptomatic and usually slow growing. They may cause different complications depending on the part of the central nervous or visual systems which they affect.

Material And Methods: Between 1997 and 2002, four patients were treated at the 1st Department of Maxillofacial Surgery of the Medical University of Warsaw for osteomas located at the border of the anterior cranial base.

[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.

[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.

[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.

[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.

[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.

[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.

[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.
