Tissue engineering is a promising method for the regeneration of oral and maxillofacial tissues. Proper selection of a cell source is important for the desired application. This review describes the discovery and usefulness of Dedifferentiated Fat (DFAT) cells as a cell source for tissue engineering. DFAT cells are a highly homogeneous cell population (high purity), highly proliferative, and possess a multilineage potential for differentiation into various cell types under proper in vitro inducing conditions and in vivo...

Facial nerve paralysis is an unusual formidable complication that can manifest after various maxillofacial surgeries, including open reduction of facial trauma. The branches more predisposed to such injury are the zygomatic and marginal mandibular branches. Zygomaticomaxillary complex (ZMC) fractures are frequently encountered in maxillofacial trauma. The facial nerve has not been described as endangered during ZMC surgery. Paralysis of the buccal branch after ZMC repair with delayed onset has been reported only once...

BACKGROUND: With the changing conditions of war, maxillofacial injuries are observed more frequently. Particularly in urban areas, high-energy explosive devices (HEEDs), such as improvised explosive devices, are often used alongside long-barreled weapons (LBWs). It is important to use trauma scoring systems and a multidisciplinary approach for medically and accurately responding to the trauma patient in a timely manner. This study aimed to compare the Military Combat Injury Scale (MCIS) and Military Functional Incapacity Scale (MFIS) between injuries sustained by LBWs or HEEDs and to share experiences of an operational field hospital...

QT prolongation is an electrocardiographic change that can lead to lethal arrhythmia. Acquired QT prolongation is known to be caused by drugs and electrolyte abnormalities. We report three cases in which the prolonged QT interval was improved at the time of operation by briefly discontinuing the drugs suspected to have caused the QT prolongation observed on preoperative electrocardiography. The QTc of cases 1, 2, and 3 improved from 518 to 429 ms, 463 to 441 ms, and 473 to 443 ms on discontinuing the use of a gastrointestinal prokinetic agent, a proton pump inhibitor, and a molecular targeted drug, respectively...

Regardless of whether it is acute or chronic, the assessment of pain should be simple and practical. Since the intensity of pain is thought to be one of the primary factors that determine its effect on a human's overall function and sense, there are many scales to assess pain. The aim of the current article was to review pain intensity scales that are commonly used in dental and oral and maxillofacial surgery (OMFS). Previous studies demonstrated that multidimensional scales, such as the McGill Pain Questionnaire, Short form of the McGill Pain Questionnaire, and Wisconsin Brief Pain Questionnaire were suitable for assessing chronic pain, while unidimensional scales, like the Visual Analogue Scales (VAS), Verbal descriptor scale, Verbal rating scale, Numerical rating Scale, Faces Pain Scale, Wong-Baker Faces Pain Rating Scale (WBS), and Full Cup Test, were used to evaluate acute pain...

The beauty of the laryngeal mask is that it forms an air tight seal enclosing the larynx rather than plugging the pharynx, and avoid airway obstruction in the oropharynx. The goal of its development was to create an intermediate form of airway management face mask and endotracheal tube. Indication for its use includes any procedure that would normally involve the use of a face mask. The laryngeal mask airway was designed as a new concept in airway management and has been gaining a firm position in anesthetic practice...
