Odontogenic Cutaneous Fistula: A Case in Aged Patient With Delayed Diagnosis.

Odontogenic cutaneous fistula is a pathologic communication between the cutaneous surface of the face and the oral cavity and it is a rare entity frequently misdiagnosed.Therefore, the lesion may persist for a long period before the correct diagnosis is made and odontogenic source is treated appropriately. Delay in diagnosis adds to the chronicity of the lesion and if not diagnosed in times fistula can even leave deforming scars.

Eosinophilic Granuloma of the Mandible: Is a Conservative Treatment Sufficient for Local Disease Control?

Eosinophilic granuloma is the most benign and common form of the Langerhans cell histiocytosis, a rare proliferative disease that can affect single or multiple organs. In the quite common head and neck manifestation these lesions can be confused in the beginning, with other bone diseases such as odontogenic cysts, periodontal disease, or malignancies. Treatment varies depending on the size, number, localization of the lesions, and patient's general conditions.

Mandibular trauma: a two-centre study.

The aims of this study were to assess and compare epidemiological data on mandibular fractures from two European centres and to perform a review of the literature. Between 2001 and 2010, a total of 752 patients with a total of 1167 mandibular fractures were admitted to a hospital in Turin, and 245 patients with a total of 434 mandibular fractures were admitted to a hospital in Amsterdam. The mean age in Turin was 34.

Inferior alveolar nerve injuries associated with mandibular fractures at risk: a two-center retrospective study.

The aim of the study was to investigate the incidence of the inferior alveolar nerve (IAN) injury in mandibular fractures. This study is based on two databases that have continuously recorded patients hospitalized with maxillofacial fractures in two departments-Department of Maxillofacial Surgery, Vrije Universiteit University Medical Center, Amsterdam, the Netherlands, and Division of Maxillofacial Surgery, San Giovanni Battista Hospital, Turin, Italy. Demographic, anatomic, and etiology variables were considered for each patient and statistically assessed in relation to the neurosensory IAN impairment.

Informed consent in orthognathic surgery.

Historically, the patient-doctor relationship has been based on trust. Adequately informing a patient confirms this relationship and fulfills the legal obligation of the physician to inform the patient to the best of his knowledge. Informed consent is the process of providing patients with the realistic and necessary information in a manner which they can understand and recall and allows them voluntarily to make an informed choice on the treatment.

Current opinions on surgical treatment of fractures of the condylar head.

Treatment of mandibular condyle fractures is still controversial, with surgical treatment slowly becoming the preferred option. However, fractures of the condylar head (diacapitular fractures) are still treated conservatively at many institutions. Recently, more and more surgeons have begun to perform open treatment for diacapitular fractures because it allows to restore the anatomical position of the fragments and disc, it allows an immediate functional movement of the jaw, and avoid the ankylosis of the temporomandibular joint induced by the trauma.

Fractures of the mandibular coronoid process: a two centres study.

The aim of this study was to assess the characteristics of patients with coronoid fractures treated in two European centres over 10 years and to briefly review the literature. This study is based on 2 systematic computer-assisted databases that have continuously recorded patients hospitalized with maxillofacial fractures and surgically treated in two European centres between 2001 and 2010. During the 10 years, 1818 patients and 523 patients with maxillofacial fractures were admitted to the two centres respectively: 21 patients (16 males, 5 females) were admitted with 21 coronoid fractures and 28 associated maxillofacial fractures.

Diplopia and orbital wall fractures.

Diplopia is a symptom that is frequently associated with orbital wall fractures. The aim of this article was to present the incidence and patterns of diplopia after orbital wall blow-out fractures in 2 European centers, Turin and Amsterdam, and to identify any correlation between this symptom and such fractures. This study is based on 2 databases that have continuously recorded data of patients hospitalized with maxillofacial fractures between 2001 and 2010.

Infraorbital nerve posttraumatic deficit and displaced zygomatic fractures: a double-center study.

Typical associated signs and symptoms of displaced zygomatic fractures include lack of zygoma projection, diplopia, and sensory disturbances of the infraorbital nerve (ION). The aim of this article was to assess eventual associations between ION sensory disturbances and zygomatic fractures patterns. This study is based on 2 databases that have continuously recorded patients hospitalized with maxillofacial fractures in 2 Departments of Maxillofacial Surgery in Amsterdam, The Netherlands, and Turin, Italy between 2001 and 2010.

Bacteriological findings in radicular cyst and keratocystic odontogenic tumour fluids from asymptomatic patients.

Objective: In this study the potential presence of bacteria in radicular cyst (RC) and keratocystic odontogenic tumour(KCOT) fluids from clinically asymptomatic patients was investigated.

Materials And Methods: Cyst fluids were collected by needle aspiration from 16 patients with asymptomatic osteolytic lesions (10 RCs and 6 KCOTs) undergoing surgery. All samples were transferred into tubes containing pre-reduced transport medium, delivered to the microbiology laboratory and processed within 1h.

Orbital lymphomas: clinical and radiological features.

The purpose of this prospective study was to evaluate the clinical and radiological features of a consecutive series of orbital lymphomas in two Institutions in the North West of Italy. A prospective study was performed of all cases of diagnosed orbital lymphomas. Data on patient demographics, symptoms and clinical findings, histological type of lymphoma, site of lesion, imaging, and systemic involvement were recorded in each case.

Late surgical treatment of posttraumatic mandibular deformity.

Delays in treatment may complicate the treatment of mandibular trauma, leading to a bone healing in an abnormal position and to a posttraumatic mandibular deformity such as malunion, malocclusion, and asymmetry. All these features may make delayed treatment a challenging issue. Therefore, early reduction and fixation of displaced mandibular fractures is mandatory to allow precocious healing and return to the normal function.

Clinical outcomes of surgical management of anterior bilateral mandibular fractures.

Purpose: The aims of this study were to assess the clinical outcomes of patients with anterior bifocal mandibular fractures and to discuss the management of this peculiar type of trauma.

Methods: From the systematic computer-assisted database that has continuously recorded patients hospitalized with maxillofacial fractures, only patients admitted with anterior bifocal bilateral mandibular fractures between 2001 and 2011 were considered. Patients were contacted, and they were invited to volunteer for a clinical follow-up examination.

Bicycle-related maxillofacial injuries: a double-center study.

Objective: Bicycle-related injuries account for an important proportion of road injuries all over the world. As only few reports have focused on the characteristics of maxillofacial fractures sustained in bicycle accidents, the purpose of this study was to present and compare epidemiological data about bicycle-related maxillofacial injuries in two European centers between 2001 and 2010.

Methods: Bicycle-related facial fractures occurred in 105 patients (79 males, 26 females) in Turin, with a percentage of 5.

Radiographic superimposition and mandibular peripheral osteoma: the importance of clinical and CT findings.

Peripheral osteomas are benign, slow-growing osteogenic tumors that are caused by centrifugal growth of the periosteum and develop as masses attached to the cortical plates.The pathogenesis of osteomas is unclear, and embryologic, traumatic, inflammatory, metaplastic, and genetic causes have been proposed. A solitary peripheral osteoma of the jaws is uncommon.

Oral hyaline ring granuloma.

Hyaline ring granuloma is a rare oral lesion with an unclear and controversial etiology, characterized by the presence of rings of palely eosinophilic structureless material (the so-called hyaline rings) with multinucleated giant cells around and within the very same rings.Various theories have been proposed about the pathogenesis of hyaline ring granulomas. Many authors consider a vegetable origin, suggesting that it may represent a reaction to foreign material such as food (and in particular pulses).

Primary bone xanthoma of the inferior orbital rim.

Primary bone xanthoma is an extremely rare benign bone tumor histologically characterized by mononuclear macrophage-like cells, abundant foam cells, and multinucleated giant cells. Xanthomas of the bone usually appear as a benign secondary manifestation of some diseases. Therefore, they are denominated primary xanthomas when the other diseases are discarded.
