RESUMO
Background and Objectives: Saliva is of utmost importance for maintaining oral health. Management of saliva flow rate deficiency recently includes salivary neuro-electrostimulation. The aim of this paper is to present a new model of salivary pacemaker-the MICROSAL device (MD), an intelligent, miniaturized, and implant-supported oral device used for salivary stimulation. Materials and Methods: This report presents the development, calibration, and first clinical tests which involved the MD. The novel features of this device are the pH sensor and the fact that it communicates with the patient's smartphone, where oral wetness and pH are graphically exposed. Saliva samples were taken before and after the MD was used on a 68-year-old patient suffering from post-irradiation xerostomia, and albumin and total protein were analyzed. Results: The device uses up to 3 V and time intervals of 2 s seconds for stimulation. The total volume of all saliva samples collected during the clinical trial was almost seven times higher after the device was used. Albumin decreased from a maximum of 0.15 g/dL to 0.04 g/dL, and total proteins from 0.65 g/dL to 0.21 g/dL, after salivary stimulation. Conclusions: The MD increased saliva secretion of the patient, and we are confident it will be a good solution for future management of salivary gland hypofunction.

Frontal bone trauma has an increasing incidence and prevalence due to the wide-scale use of personal mobility devices such as motorcycles, electric bicycles, and scooters. Usually, the patients are involved in high-velocity accidents and the resulting lesions could be life-threatening. Moreover, there are immediate and long-term aesthetic and functional deficits resulting from such pathology. The immediate complications range from local infections in the frontal sinus to infections propagating inside the central nervous system, or the presence of cerebrospinal fluid leaks and vision impairment. We review current trends and available guidelines regarding the management of cases with frontal bone trauma. Treatment options taken into consideration are a conservative attitude towards minor lesions or aggressive surgical management of complex fractures involving the anterior and posterior frontal sinus walls. We illustrate and propose different approaches in the management of cases with long-term complications after frontal bone trauma. The team attending to these patients should unite otorhinolaryngologists, neurosurgeons, ophthalmologists, and maxillofacial surgeons. Take-home message: Only such complex interdisciplinary teams of trained specialists can provide a higher standard of care for complex trauma cases and limit the possible exposure to further legal actions or even malpractice.

Horton's arteritis is found in the literature under various names, such as temporal arteritis, Horton's disease senile arteritis, granulomatous arteritis or giant cell arteritis (GCA). The pathogenic mechanism is the result of an inflammatory cascade triggered by a still unknown factor that causes dendritic cells in vessels to recruit T cells and macrophages, which form granulomatous infiltrates. The clinical picture consists of a daily headache with temporal localization, with moderate to severe intensity, unilateral or bilateral, with a history of months, years. Other changes may include pain in the cheek or tongue during chewing (claudication), weight loss, generalized fatigue, low-grade fever, and frequent pain in the limbs, in the context of coexisting rheumatic polymyalgia. Visual symptoms represent a special category, involving blurred vision, scotomas, and even sudden blindness. Histopathological examination of the temporal artery biopsy reveals focal thickening of the intima, with interruption of the lamina propria, with transmural inflammatory infiltrates, sometimes with multinucleated giant cells. In this article, we aim to review the role of temporal artery resection in the diagnosis of Horton's arteritis, but we also discuss the hypothesis of a potential therapeutic benefit of this procedure. However, there are also clinical situations in which there has been a considerable improvement in clinical symptoms and especially in vision deficit, with the improvement of the visual field after surgery performed for biopsy. It is difficult to estimate the influence of temporal artery resection alone, given that most patients also have concomitant cortisone treatment. However, in some cases, the rapid improvement of symptoms immediately after surgery, with the improvement of visual acuity and visual field, along with the disappearance of the headaches, can create the premises for future studies on a therapeutic contribution of temporal artery resection in GCA.
RESUMO
PURPOSE: The purpose of this paper is to present a rare case of osteoma localized in the left frontal sinus. A 22-year-old woman who arrived at the Department of Neurosurgery of the University Emergency Hospital, Bucharest, Romania, presented a vertical asymmetry of the eyeballs but displayed no clinical signs like pain or diplopia. The computer tomography exam was used for preoperatory diagnostic. Histopathology was performed after surgery using Hematoxylin and Eosin staining. The Nikon Eclipse microscope was used to examine the slides. RESULTS: The histopathology exam shows a compact osteoma with dense and non-Haversian bone tissue and parallel bony trabeculae. A few spaces for the marrow were also found. The osteocytes were small and no fibrous cells were discovered. CONCLUSIONS: The computer tomography and histopathology exam were the investigations that lead us to a true diagnostic of dense osteoma. This tumor was the first case of frontal sinus osteoma histologically described in the Romanian population.

INTRODUCTION: Facial trauma is a common injury in the urban setting. Many studies have been published on the epidemiology and treatment of facial fractures, but few of them conducted in emergencies hospital as ours. The purpose of this study was to present theory and practice in surgical treatment of midface trauma. MATERIALS AND METHOD: We will present a retrospective study and a cases series report with our personal experience in diagnosis and treatment of middle floor facial trauma. Craniofacial trauma in context of polytrauma involves a screening condition assessment of the patient to prioritize lesions and frequently require a multidisciplinary approach: neurosurgeon, ENT surgeon, maxillo-facial surgeon, ophthalmologist, plastic surgeon and so on. Axial and coronal CT are mandatory and three-dimensional CT reconstruction can be extremely useful. Surgical indication in middle floor facial trauma is given by functional and aesthetic deficits. RESULTS: We will present the surgical principles we use in treatment of fractured nose, in fractures of maxilla, in fractures of the zygomatic arch with or without zygoma body fractures and fractures of the floor of orbit. DISCUSSIONS: The surgical technique was imposed by coexisting lesions of neuro and viscerocranium, by the complexity of the fracture, by functional or aesthetic deficits and by our surgical experience. CONCLUSIONS: The main principles in middle face trauma are an accurate and complete lesions evaluation; mixed surgery team with maxillofacial surgeon and neurosurgeon.
RESUMO
The management of orbital fractures is one of the most interesting and difficult areas in facial trauma. The consequences of an orbital fracture are sometimes dramatic. They include varying types of defects from a loss of vision to diplopia, loss of an eye, epiphora, a disturbing loss of facial sensation, or even an unacceptable appearance of the eye and the hard and soft tissues around it. The controversies surrounding orbital fractures, and orbital floor fractures in particular include the following: the timing of primary surgery (early or late), bone grafting versus alloplastic materials, the management and prevention of diplopia, the prevention of enophtalmos, the management of infraorbital nerve numbness or dysesthesia.
RESUMO
ABSTRACT: The optimal treatment of frontal sinus fractures remains controversial. Multiple treatment options and algorithms have been proposed by multiple specialties throughout the years; however, the optimal method of frontal sinus repair has yet to be discovered. Overwhelming complications such as meningitis, encephalitis or brain abscess are quite uncommon nowadays. Nevertheless, late development of invasive mucoceles is not a rarity and therefore long-term follow-up is mandatory.
