Soung Min Kim, Emmanuel K Amponsah, Hui Young Kim, Ik Jae Kwon, Hoon Myoung, Jong Ho Lee
: Ameloblastoma is the most common benign odontogenic tumor of the jaw, and expansional growth of a huge untreated ameloblastoma can result in disturbances in facial aesthetics and function, such as difficulty with mouth opening, swallowing, chewing, breathing, neurologic deficits, and pathologic fractures. Radical wide resection with safety margins and subsequent reconstruction is generally recommended. A fibular free flap (FFF) is commonly used to reconstruct the mandible in order to adequately restore both aesthetic appearance and function...

We present a case of a parapharyngeal schwannoma of the mandibular nerve with intraosseous extension into the mandible. The initial symptoms included decreased auditory acuity, with subsequent magnetic resonance imaging findings suggestive of Eustachian tube obstruction. This represents a rare symptom of schwannomas of the mandibular nerve. Owing to the degree of bony expansion and cortical thinning of the adjacent mandibular ramus, concern existed for a pathologic fracture. Treatment involved complete excision of the lesion using hemimandibulectomy with second stage reconstruction...

INTRODUCTION: The mandible consists of different segments, each of which possess its own specific characteristics regarding emergence, ossification during growth and pathologies. Orthodontists need to be very familiar with these developmental anomalies if they are to avoid failure in their orthopedic or orthodontic treatments and in order to understand the reasons for the lack of success of "conventional" treatments. Each segment must develop correctly if the mandible is to achieve optimal development and occupy a normal position within the cranio-facial complex...

PURPOSE: To present a case report on the presence of an ectopic mandibular third molar (EMTM), the surgical treatment, and outcome. CASE REPORT: A 63-year-old woman presented with right preauricular facial swelling, limited jaw function, and pain. Radiographic assessment demonstrated an EMTM positioned in the superoposterior aspect of the ramus. Radiographically, there was a bony tunnel extending from the third molar to distal of the second molar. The patient was treated by an intraoral approach on the medial aspect of the ramus for removal of the ectopic third molar, as well as the tissue in the bony tunnel...

Factors associated with the diagnosis, aetiology, and treatment of mandibular fractures occurring during the postoperative period following the removal of a lower third molar are discussed. The following databases were searched using specific key words: PubMed/MEDLINE, LILACS, Embase, and Scopus. The search yielded 124 cases. Sex, age, side, tooth position and angulation, bone impaction, relationship between the tooth and the inferior alveolar nerve, local pathological conditions, aetiology of the fracture, symptomatology, and time between surgery and fracture, as well as any displacement of the fracture and the treatment of the fracture, were evaluated...

BACKGROUND/AIMS: Intermaxillary fixation is a standard procedure for the treatment of mandibular fractures or in orthognathic surgery. Pre-drilling for screws poses the risk of accidental tooth-root injury, potentially leading to further pathological processes. Limited evidence about accidental tooth injury during intermaxillary fixation is available due to heterogenous study designs. The aim of this study was to evaluate the risk of root trauma using pre-drilled transgingival fixation screws and the clinical consequences for the affected teeth...

PURPOSE: Iatrogenic fracture of mandible (IFM) associated with exodontia though rare, they do occur with an incidence ranging from 0.0034 to 0.0075 %. Most of the data is in the form of case reports or a small case series. This is an attempt to amass the data available in literature since the last 62 years. The purpose of this meta-analysis is to identify the etiologies and risk factors leading to IFM associated with exodontia and also the measures to minimize the complication. METHODS: Articles published between 1953 and 2015 were searched in Medline database...

Background. The inferior alveolar canal should be examined as a significant anatomical landmark, particularly in the posterior body and ramus of the mandible, for dental and surgical procedures. In the present study, the effects of two pathological lesions, ameloblastoma and keratocystic odontogenic tumor, on canal displacement were investigated. Methods. This study had a single-blinded design. Twenty-six patients with lesions in the mandible referred to Imam Reza Hospital, Tabriz, Iran, were studied in two equal groups (13 patients with a histopathological diagnosis of ameloblastoma and 13 with a histopathological diagnosis of odontogenic keratocyst)...

Craniofacial microsomia remains the second most common craniofacial deformity after cleft lip and palate. Mandibular pathology has been classically scored from type I to type III by the modified Pruzansky-Kaban classification. The authors report a case of a 5-year-old patient with Goldenhar syndrome and bilateral type III craniofacial macrosomia. The patient had absence of bilateral glenoid fossas, condyles, coronoids, and rami as well as hypoplasia of the symphysis, parasymphysis, and mandibular body. Reconstruction was performed using 2 costochondral rib autografts to reconstruct a ramus and assist in the development of a neo-glenoid fossa at the cranial base...

The keratocyst odontogenic tumor (KCOT) represents a rare and benign but locally aggressive developmental cystic lesion usually affecting the posterior aspect of the mandible bone, the treatment of which has always been raising debate, since Philipsen first described it as a distinct pathological entity in 1956.Recent studies have proposed the use of endoscope-assisted surgical technique, due to the possibility given by the endoscope of improving the effectiveness of the treatment of these lesions thanks to a better visualization of operative field and though a better understanding of the pathology...

This study describes a case of myxoid chondrosarcoma of the mandible in a 22-year-old male patient. A tumour in the buccal gingiva of the lower left premolar region had been identified 2 years earlier. Whole-jaw panoramic radiographs showed a hypodense shadow in the mesiodistal area near the roots of teeth 34 and 35. A maxillofacial computed tomography scan revealed a mass in the lower left premolar soft tissue, with a shadow indicating bone destruction, a clear boundary and uniform density. The preliminary diagnosis at the outpatient department was 34-35 epulis...

Low-grade fibromyxoid sarcoma (LGFMS) is a distinctive variant of fibrosarcoma with a high metastasizing potential and is characterized by a long interval between tumor presentation and metastasis. LGFMS involving the maxillofacial region is a very rare entity with only six cases reported till date. LGFMS is characterized by its benign histological appearance, with spindle cells in whorling pattern, and collagenized and myxoid areas. The heterogeneous histological appearance makes the diagnosis challenging...
