Lymphatic malformations are rare slow-flow vascular malformations, with high tendency to appear in the head and neck region. The treatment of these lesions ranges from follow-up to sclerosing agent injection to surgical excision. The authors present a case of a new born with large extensive lingual and submandibular lymphatic malformation, for which the patient underwent tracheostomy and gastrostomy insertion. He was then treated successfully with sclerosing agent injections followed by surgical excision, with 7 years follow-up...

REVIEW
Kai H Lee, Andrew Hughes
Facial trauma is commonly associated with excessive consumption of alcohol and is often associated with interpersonal violence or motor vehicle accidents. Alcohol-related trauma presentation to hospitals causes a major service burden, and there have been efforts to reduce such trauma load with educational programs and social support. Brief alcohol intervention (BAI) in an acute setting (emergency department or trauma centre) has been shown as an effective means to reduce future alcohol intake and the incidence of future alcohol-related injuries, especially in the period immediately following injuries...

BACKGROUND: Tongue resection is a surgical challenge because of its adverse effects on language articulation, swallowing, respiration, the eventual quality of life, and poor prognosis of advanced disease. To date, the currently accepted standard treatment has been based on excision of the primary lesion with a 1.5-2-cm circumferential macroscopic margin. Compartmental tongue surgery (CTS) is a surgical technique that removes an anatomo-functional compartment containing the primary tumor...

Subgemmal neurogenous plaque (SNP) is a biphasic neural structure associated with the taste buds. Clinically, SNP usually presents as an asymptomatic, normally colored, papule located in the posterior lateral border of the tongue. Accurate diagnosis is based only on histopathological examination, which shows a superficial neurofibroma-like pattern and a neuroma-like in the deep zone. Appropriate recognition of clinical and morphological aspects of SNPs can avoid their misdiagnosis as neural neoplasms. We report three cases of SNP with detailed clinical, histopathological, and immunohistochemical features...

PURPOSE: The present study aims to describe three cases of patients inflicted by rubber bullets with severe facial fractures. METHODS: In addition, a review of English-language literature involving facial fractures by rubber bullets from 1975 to 2016 was performed. RESULTS: This current study demonstrated that the use of the LLRBW is unsafety even when applied by police enforcements exclusively. CONCLUSIONS: Management of facial fractures caused by LLRBW is done in a usual manner with closed or open reduction associated with bone mini-plates or reconstruction plates when indicated...

In recent years, several studies related to fixation systems have been published, but few suggest any variations of the Le Fort I osteotomy technique, and the use of plates and screws placed along the canine and zygomatic pillar are common. The 20-year-old patient with Crouzon syndrome presented with severe hypoplasia of the maxillary, mandibular prognathism, and class III facial pattern. The patient underwent orthognathic surgery and high Le Fort I osteotomy with the fixation of eight positional screws. The aim of this paper is to describe a different technique for the fixation in high maxillary osteotomies, which can be used in specific cases...

PURPOSE: The installation of implants has become a routine procedure in the clinic. However, it takes time and adequate bone thickness, and for that, tissue engineering has made efforts to develop substitutes for autografts, in view of certain disadvantages of this material. The decision to choose the most suitable graft material for each case is an important step in the success of bone reconstruction. This study was to verify, by means of immunohistochemical study, that the addition of bone morphogenetic protein had some influence on biomaterials commercially available, taking into account the formation of mineralized tissue, bone replacement, and the amount of degradation of biomaterials...
