Remplacement total de l’articulation temporo-mandibulaire par prothèse
2013
Summary Introduction The temporomandibular joint (TMJ) may be the location for tumoral, post-traumatic, degenerative, inflammatory, or congenital diseases requiring a prosthetic replacement. We present a technical note for total TMJ replacement with a Biomet ® Microfixation prosthesis (Jacksonville, FL, USA). Technical note The preoperative data includes dental panoramic X-ray, MRI of the TMJ, and CT-scan (or cone beam) of the facial skeleton. The last two mentioned examinations allow three-dimensional reconstructions and stereo-lithographic models required for surgical planning. The prosthetic device includes a temporal ultra-high density polyethylene component and a mandibular chrome-coba…
Juvenile psammomatoid ossifying fibroma of Orbit-A rare case report and review of literature
2021
Fibro osseous lesions of the craniofacial skeleton are a benign condition in which the normal architecture of the bone is replaced by fibrous connective tissue with varying degrees of mineralization. JOF forms a special entity among the fibro osseous lesions because of its age of occurrence and its aggressive nature thereby mimicking a malignancy. The Juvenile Ossifying Fibromas were further subdivided into Psammomatoid and Trabecular variant based on their histopathological characteristics. They tend to differ in their mineralized portion with the trabecular variant showing woven bone while the psammamotoid shows lamellated and spherical ossicles in various shapes in a myxoid stroma interm…
Endoscopic dissection of dura and craniotomy with minimal trephines: a preliminary series.
1998
The first nine clinical cases using endoscopic dissection of dura and craniotomy with minimal trephines were performed from June to August 1997 after trial dissection of 19 fresh cadavers conducted at the University of Brno's Pathology Institute in the Czech Republic. These procedures involved the refinement of craniofacial and intracranial surgical techniques using the endoscope and prototype instruments. These dissections demonstrated that intracranial structures can be explored using an endoscope without encumbrance, and that major craniofacial surgeries may also be performed with minor incisions and minimal craniotomies. Furthermore, we seek to illustrate that use of the endoscope in cr…
Association between eruption state of the third molar and the occurrence of mandibular angle fractures.
2015
Background/Aim Fractures of the mandible, especially the mandibular angle, are one of the most frequent types of injuries of the facial skeleton. In many cases, a retained third molar can be found in the line of the fracture. However, it remains unclear whether a relationship between third molars and mandibular angle fractures exists. Materials and Methods Patients with isolated or combined fractures of the lower jaw between January 2001 and December 2007 were analyzed retrospectively. Electronic health records were investigated regarding the types of mandibular fractures, and panoramic radiographs were reviewed concerning the existence of third molars. In addition, a systematic review was …
Imaging Evaluation of Facial Complex Strut Fractures
2012
High-resolution multidetector computed tomography with multiplanar reformations and 3-D postprocessing often provides the detail necessary for preoperative assessment of facial injuries. Maxillofacial fractures are classified in the following manner: upper face fractures, midface fractures (the most frequent), Le Fort fractures, and lower face or mandible fractures. The facial skeleton is a framework of vertical and horizontal buttresses that ensures a better resistance to trauma, but serves also as reference for maxillofacial surgery to restore facial size and shape. Radiologists should know how to diagnose and report the main types of facial fracture.
The face of conflict: Significant sharp force trauma to the mid-facial skeleton in an individual of probable 16th–17th century date excavated from By…
2016
A variety of injuries have always been associated with violence, consequences of which people had to deal with. In this paper we present a complex of craniofacial and dental injuries resulted from sharp force trauma. The basis of our study was historical skeletal material excavated from archeological site in Byczyna (11th–17th century), Poland. An individual whose skeleton was exhumed from the grave No. 610 exhibited healed, oblique trauma of the left maxilla, damage to the crowns of right central and lateral incisors and concomitant luxation of the right maxillary central incisor. We describe the mechanism of this trauma and complications that resulted from damage to the masticatory appara…
