This article introduces the combined application of vacuum sealing drainage (VSD) and chymotrypsin in the treatment of post-operative mandibular osteomyelitis. The lesion was washed by chymotrypsin (4000U) and saline (500 ml). VSD is effective in the treatment of traumatic mandibular osteomyelitis. This study investigates the effect of VSD combined with chymotrypsin in the treatment of patients with osteomyelitis after mandibular trauma. It is proved that it has a good effect in ensuring drainage, controlling infection and retaining internal fixation, and can create a good environment for fracture healing...

The need to treat fractures of the mandibular condyle remains controversial, but when the decision to operate has been made, then multiple forms of fixation are advocated. Traditionally, metal plates and screws have been used, but this is thought to have several disadvantages, particularly in the growing skeleton. Resorbable fixation for maxillofacial fractures has not gained widespread acceptance because of technical difficulties with the materials and concern about inflammatory reactions during their resorption...

The purpose of the current study was to assess the biomechanical behavior of 5 different fixation schemes for unfavorable mandibular angle fractures using the three-dimensional finite element analysis method. Five different miniplate fixation schemes were modeled for the fixation of unfavorable mandibular angle fractures. A double parallel miniplate (M1), which was placed at the halfway point of the mandibular angle height; a 1/3 superior-positioned miniplate (M2); a single miniplate (M3), which was placed at the halfway point of the mandibular angle height (1/2 middle-positioned); a 1/3 inferior-positioned miniplate (M4); and an X-miniplate which was placed at the halfway point of the mandibular angle height (M5)...

The main characteristic feature of the pediatric mandible is that of decreased dimension, which leads to compromises in the open reduction and internal fixation (ORIF). In the dental segment, the cervically bulbous short stature primary teeth might act an obstacle during the maxillomandibular fixation conventionally. An increased osteogenic potential of bones favors rapid consolidation and remodeling in the affected region. The mixed dentition of the ugly duckling stage adds more burden while stabilizing the fractured segments...

We know of no universally accepted classification for intracapsular condylar fractures. We propose here a new classification based on the concept of a "disc-condyle" unit, and validate the classification based on outcomes of treatment. From 1 January 2010 - 31 December 2014, 55 patients with unilateral intracapsular condylar fractures were classified into three types: type A has no reduction in mandibular height or displacement of the disc (n=7); type B has displacement of the disc with no reduction in mandibular height (n=17); and type C has reduced mandibular height with or without displacement of the disc (n=31)...

Background: In recent years, the techniques used to identify human remains post accidents, trauma or in case of criminal investigation have been expanded, improved and rendered more complex by the emergence of technologies based on deoxyribonucleic acid (DNA) analysis. In the head and neck area, tooth has been proven to be the best quantitative source for DNA but in certain cases where the mandible specimen is edentulous or the tooth is extensively destroyed with caries, large dental restorations, mobile, or if they show any perimortem or postmortem fractures, sampling of such tooth specimen is usually avoided...

Mandibular fractures constitute a major portion of maxillofacial trauma and may lead to considerable functional and aesthetic sequelae if treatment is inadequate or delayed. An epidemiology study on mandibular fractures may guide the preventive efforts of the Taiwan public health care system. Therefore, a retrospective review was conducted at a medical center in central Taiwan to evaluate the current mandibular fracture epidemiology.The medical records and digitized radiographs of 198 patients who received treatment for mandibular fractures during a 3-year period (from October 2010 to September 2013) at a medical center in central Taiwan were reviewed to obtain demographic and injury data...

Hong-Wei Wang, Chun-Yue Ma, Xing-Jun Qin, Chen-Ping Zhang
RATIONALE: Familial gigantiform cementoma (FGC) is a rare benign autosomal dominant fibrocemento-osseous lesion generally limited to the facial bones, typically in the anterior portion of the mandible; it is often associated with abnormalities of the long bones and prepubertal pathologic fractures. Owing to the small number of such patients, a uniform treatment criterion has not been established. This paper presents a patient with FGC who was treated in our department, and offers a systematic review of the patients reported in the literature...

RATIONALE: Corrosion refers to the degradation of a material that occurs following its interaction with other substances in the environment. Corrosion of metallic substances into tissues may lead to inflammatory responses such as systemic contact dermatitis (SCD), a skin condition where an individual who has previously been sensitized to a particular allergen via the cutaneous route will subsequently react to same allergen via the systemic route. This condition occurs following exposure to allergens such as metals, medications, and certain food substances...

Introduction: Treatment of edentulous atrophic mandible with severe atrophy is a challenge based on local conditions and systemic diseases confronted by the age group affected. If bone grafting is indicated, it is often used in lateral or inferior aspects of the mandible. Case Report: A 70-year-old male with a unilateral fracture of the atrophied left mandibular body was managed by lingual bone grafting and inferior border miniplate fixation to prevent two common problems after fracture healing; the need for plate removal before denture fabrication and facial asymmetry in the unilateral body fracture...

Ectopic molars within the mandibular ramus/condyle unit, although rare, present a unique challenge to the surgeon. Multiple approaches have been described in the literature for their removal. A review of the English literature on the subject of mandibular ectopic molars and their epidemiology, etiology, indications for removal, and surgical techniques was completed. In addition, a case report is presented of an ectopic mandibular molar in the mid-ramus region which was removed via a minimally invasive, intraoral, technique combining the use of endoscopy and piezoelectric surgery...

Bilateral sagittal split ramus osteotomy (BSSRO) is commonly used to correct mandibular prognathism or retrognathism. Patients with mandibular prognathism or retrognathism may also present with a prominent mandibular angle. In this paper, we share our experience on BSSRO with mandibular angle resection. Eleven patients who were treated from July 2014 to December 2016 were included in this study. The mandibular angle was resected through the medial side of the mandible after BSSRO. The mandibular angle measurements of the patients changed significantly after surgery (pā€‰<ā€‰0...
