Mucocele superficial em lábio inferior: relato de caso

Mucoceles are mucous cysts related to obstruction or trauma of the minor salivary glands. The preferential localizations are lower lip, the soft palate, mandibular retromolar region, and oral mucosa. Microscopically they are subepithelial extravasations of sialomucin that occur at the epithelial connective tissue interface. The diagnosis of superficial mucocele is mainly clinical, and a biopsy is rarely indicated. This report describes a lesion of the lower lip that was definitively diagnosed by histologic examination as a mucocele or mucus retention phenomenon.Mucoceles são cistos mucosos relacionados com a obstrução ou trauma das glândulas salivares menores. Preferencialmente, estão localizadas no lábio inferior, palato mole, região retromandibular e mucosa oral. Microscopicamente, constituem-se em extravasamento subepitelial de sialomucina, que ocorre na interface do tecido epitelial conectivo. O diagnóstico da mucocele superficial é principalmente clínico, sendo raramente indicada a realização de biópsia. Este artigo descreve uma lesão em lábio inferior cujo diagnóstico definitivo foi de mucocele, ou fenômeno de retenção de muco

Patient?s perception of improvement after surgical assisted maxillary expansion (SAME) : pilot study

Objective: Clinicians often assume that changes following orthognathic surgery are both physically and psychologically beneficial to the patient. The present study investigates patient perception regarding improvement after surgically assisted rapid maxillary expansion. Study design: A survey with twenty-three patients was carried out to identify satisfaction with the surgical outcome and assess whether the surgery met patient expectations. General information was also collected on schooling, age, gender, chief complaint and reasons for seeking treatment. Results: Most patients (n = 19; 82%) were advised to undergo surgery by a dentist. Twenty-two (95%) patients reported being satisfied with the operation procedure. Twenty-one (91%) patients reported that the procedure met their expectations. Nineteen respondents would undergo the same operation again and would recommend treatment to others with similar problems. Conclusion: The need for surgery associated with orthodontic appliances to correct a transverse maxillary deficiency requires a proper explanation to patients regarding the procedure and postoperative period in order to ensure realistic expectations concerning the surgical goals

Reduction and fixation of unstable fractures of the zygomatic arch: Report of a series of cases

Background: This study evaluated a series of cases of fracture in the zygomatic arch with displacement of the fractured segment.Materials and Methods: This prospective cohort study was conducted between May 2008 and February 2009. The study sample which consist of 10 patients of both genders with fractures in the zygomatic arch. The collection instrument included a specific sheet with data concerning the patient’s age, cause, side of the fracture, type of treatment performed, recurrence and presence of lesions in the facial nerve. The radiographic indices of Waters and Hirtz were used. The data were presented by means of descriptive statistics (absolute and percentage distributions).Results: Most of the patients were male (90.0%), the most frequent etiology was a motorcycle accident (70.0%) and the left side was more affected (60.0%). There was no recurrence in any of the patients examined; however, 1 patient had a lesion in the facial nerve. The treatment performed for all patients was reduction and fixation with titanium miniplates.Conclusion: Fractures in the zygomatic arch are more frequent in young male individuals and the most common cause is a motorcycle accident, with the use of miniplates constituting an effective treatment without recurrence.Keywords: Accidents, facial injuries, maxillary fractures, traffic, zygomatic fracture

Facial traumas among females through violent and non-violent mechanisms

INTRODUCTION: Injuries stemming from facial trauma have both physical and emotional consequences among affected individuals as well as an economic impact on the healthcare system. OBJECTIVE: The aim of this retrospective study was to determine the occurrence of facial trauma among females of different age groups treated at an urgent care ward in the northeast of Brazil in a two-year period. MATERIALS AND METHODS: A cross-sectional study was carried out involving 247 charts. Data on patient age, etiological agent and site of trauma were recorded. RESULTS: Adults accounted for 48.6% of the sample. Falls were the most frequent cause of trauma (38.5%); soft tissue injuries were the most prevalent ones (67.6%); age was significantly associated with the etiology of the injuries; falls were the most common cause among children/adolescents and elderly individuals, and acts of violence were more common among adults. CONCLUSION: Adult females were affected by facial trauma more than the other age groups studied, with a predominance of soft tissue injuries and injuries to the mandible, maxilla, zygomatic arch and nasal bones. Falls were the most prevalent cause of facial trauma and significantly associated with the youngest (children/adolescents) and oldest (elderly individuals) age groups

Additive Manufacturing for Surgical Planning of Mandibular Fracture

Currently, imaging techniques such as Computed Tomography with three-dimensional reconstruction (3D) and Magnetic Resonances are being routinely used in pre-surgical planning in all fields of medicine. Nowadays, virtual three-dimensional images, commonly displayed on two-dimensional surfaces, such as the computer screen, can be used to produce rapidly prototyped models, with excellent dimensional accuracy and fine reproduction of anatomical structures, providing professionals with the ability to use the biomodel in planning and simulating medical and dental procedures (oral and maxillofacial surgery, making individualized facial implants and prostheses, measurements and previous adaptations of prefabricated fixation plates), thus contributing to considerable reductions in surgical time and consequently the duration of anesthesia, minimizing infection risks and reducing hospital costs. In this report, we describe a case of surgical planning and treatment of bilateral atrophic mandibular fracture, in which, for surgical planning, authors used Rapid Prototyping as an adjunct tool, considering the advantages already outlined
