Mandible Fracture Patterns after Low Kinetic Energy Trauma Common in an Urban Level I Trauma Center

alwin shared this article with you from Inoreader
Facial trauma and fractures are injuries that may require attention from emergency departments (ED). The Nationwide Emergency Department reported that in 2007 alone 407,167 ED visits included a facial fracture, with annual costs close to $1 billion.1 Of these, 1 of the most common injury sites of the maxillofacial region is the mandible.2 Despite previous studies having shown trends in etiology, epidemiology, and treatment outcomes, there is still no consensus on culture-, city-, and facility-specific variables by reporting trauma centers.3 For example, some studies mention motor vehicle accidents and interpersonal violence as leading causes of mandibular fractures, while other studies list falls, all with varying geographic influences as well.

Are Bacteria Just Bystanders in the Pathogenesis of Inflammatory Jaw Conditions?

alwin shared this article with you from Inoreader
It is unclear whether certain bacteria initiate the development of inflammatory jaw conditions, or whether these diseases create a milieu for dysbiosis and secondary colonization of indigenous flora. At present, there are no comparative studies on the types of bacteria that colonize different inflammatory jaw conditions. Accordingly, this study aims to identify and compare the types of bacteria isolated in osteomyelitis, osteoradionecrosis, and MRONJ. (Source: Journal of Oral and Maxillofacial Surgery)

Oral Rehabilitation of an Adult Cleft Palate Patient with Zygomatic Implant-supported Obturator Prosthesis: A Case Report

alwin shared this article with you from Inoreader
With advancement in medical services and their accessibility across the country, as well as growing awareness among the patient population, it is rare to find an adult with an untreated cleft lip and/or palate nowadays. Treatment of these patients to restore form and function can be challenging, often yielding less-than-satisfactory outcomes. In current literature, there have been case reports of patients with atrophic maxilla or severe maxillary defects after oncologic resections, where zygomatic implants have been utilized for fabrication of a fixed maxillary prosthesis.

Intraoperative flap warming: The novel use of a sterile cardiac forced warm air blanket for maintaining optimal flap perfusion.

alwin shared this article with you from Inoreader
The two-team approach in major head and neck/reconstructive surgery can occasionally lead to delays between flap harvest and detachment, due to the complexity and length of the ablative procedure. In order to minimize the potential for flap cooling and the adverse impact on microcirculation, active warming can be beneficial.(1) Intraoperative flap warming to either maintain or improve circulation during free flap harvesting has been performed with a variety of passive and active techniques,(2) however limitations such as a lack of consistent temperature regulation, lack of sterility, inability to directly visualise the flap or the need for acquisition of new equipment for a niche area meant that an ideal solution was lacking.

Phonetica. 2022 Apr 15. doi: 10.1515/phon-2022-2018. Online ahead of print.ABSTRACTThe current study extends traditional perceptual high-variability phonetic training (HVPT) in a foreign language learning context by implementing a comprehensive training paradigm that combines perception (discrimination and identification) and production (immediate repetition) training tasks and by exploring two potentially enhancing training conditions: the use of non-lexical training stimuli and the presence of masking noise during production training. We assessed training effects on L1-Spanish/Catalan bilingual EFL learners' production of a difficult English vowel contrast (/æ/-/ʌ/). The participants (N = 62) were randomly assigned to either non-lexical (N = 24) or lexical (N = 24) training and were fu...
