Modified surgical technique for transposition of the inferior alveolar nerve followed by immediate placement of endosseous implants in mandibles with moderate to severe atrophy are presented. Five transpositions of the inferior alveolar nerve together with the installation of 10 implants were performed in four patients. The mean postoperative follow-up time was 17 months, with a range of 8 to 20 months. All implants with functioning pontics remained stable, with no mobility or symptoms of pain and infection during the follow-up period. Neurosensory evaluation was performed using the two-point discrimination test. Two patients had objective neurosensory dysfunction at postoperative, but all the nerve function were reported as normal by the patients 4 months postoperatively.

In this report, we describe a case of brain abscess due to odontogenic infection. A 53-year-old female who had been suffering from headache and trismus for two weeks visited the Department of Oral and Maxillofacial Surgery at the Sun Dental Hospital (Daejeon, Korea). Even after several routine tests, we still could not make a diagnosis. However, after the combined multidisciplinary efforts of oral surgeons and neurosurgeons, the patient was treated for odontogenic infection and made an uneventful recovery. Therefore, patients with infections in the head and neck region showing symptoms such as headache, changes in mental state, nausea, vomiting, seizures, hemiplegia, speech disturbance, and visual disturbance, a brain abscess should be included in the list of differential diagnoses.

Sodium hydroxide or caustic soda is a corrosive agent that can cause extensive damage to the oral mucosa, lips, and tongue when ingested either accidentally or intentionally. These injuries include microstomia, shallow vestibule, ankyloglossia, speech impairment, loss of teeth and impairment in facial expression. In the present article, we report a unique case of tongue adhesion to the mouth floor and its surgical management in a 66-year-old female patient, who had a history of caustic soda ingestion.

Infections of the oral and maxillofacial region are one of the most common conditions for which a patient presents to a maxillofacial surgeons. Although these infections can arise from a variety of source, dental disease is the most common etiology. So, odontogenic infection are frequently encountered in the practice of oral and maxillofacial surgery. These infections often respond to antimicrobial chemotherapy or surgical intervention, such as extraction of teeth, incision and drainage through clinical features. But, odontogenic infections have the potential to spread via the fascial spaces in the head and neck region, and, they spread to cavernous sinus, deep musculofascial space and other vital structure. We have undertaken clinical studies on infections in the oral and maxillofacial regions by analyzing retrospectively hospitalized patients in the Dept. of Oral and Maxillofacial Surgery, Chonbuk National University Hospital past 5 years from 2000 to 2004. And, the patients' age, sex, medical history, causes of the infection, surgical intervention, and other clinical parameters were reviewed. The obtained results were as follows : 1. The most frequent cause of oral and maxillofacial infection was odontogenic. And in the odontogenic cause, dental caries was the most common cause (47.2%). 2. The most common fascial space involved was the submandibular space (15.7%), followed by the buccal space (14.8%). 3. 60.4% of all patients required surgical drainage of the abscess, endodontic treatment or tooth extraction or periodontal treatment with drainage. 4. The most causative organism isolated from the pus culture were streptococcus viridans (53.9%). 5. Underlying medical problems were found in 136 patients (41.9%), the most common being hypertension (27.9%) and diabetes (14.7%).

Platelet-rich plasma is an autologous source of platelet-derived growth factor and transforming growth factor beta that is obtained by sequestering and concentrating platelets by gradient density centrifugation. We have used platelet-rich plasma for bone graft, especially allobone graft, at implant surgery, sinus lift procedure, and cyst enucleation. This article is retrospective study from October 1999 to November 2000. All cases were good healing and clinical success.

Ameloblastomas are generally considered to be benign tumors of odontogenic epithelial origin with high local recurrence. Rarely ameloblastomas exhibit malignant behavior with development of metastases. In this report, we present a 19-year-old woman with ameloblastoma in the right ascending ramus and multiple recurrences. Eleven years after first therapy, ameloblastoma metastasized to ipsilateral submandibular lymph node. We also review literature about cause, treatment and work-up of malignant ameloblastoma.

Purpose: Most cases of oral and maxillofacial infections are usually easily treated by proper diagnosis, elimination of causative factors, and antibiotic therapy. However, the emergence and the increase of multidrug-resistant bacteria make treatment challenging. "ESKAPE" pathogens are the most common opportunistic organisms in nosocomial infections and have resistant to commonly used antibiotics. There are many medical reviews of ESKAPE pathogens, but few in dentistry. This study focuses on oral and maxillofacial infection especially with ESKAPE pathogens. The purpose of this study is to prepare feasible data about tracing and treatment of infection related to pathogens that may be beneficial to clinicians. Methods: A total of 154 patients with oral and maxillofacial infections were reviewed by analyzing retrospectively hospitalized data in the Department of Oral and Maxillofacial surgery, Chosun University Hospital, Korea, past 5 years from January 2014 to December 2018. Based on the medical records and microbiological tests, the results were divided into two groups: infections with ESKAPE pathogens and other bacteria. Results: A total of 22 species were isolated from 154 patients. The proportion of ESKAPE pathogens among all bacterial isolates collected from infected patients was 39.6%. Causative factors, especially in post-operative infection, showed a statistically significant correlation to ESKAPE infections (29 cases). And average of treatment period in ESKAPE group was longer than non-ESKAPE groups. Overall, Klebsiella pneumoniae (60.7%) was the most frequently isolated ESKAPE pathogen. And high antibiotic resistance rates had been detected in the ESKAPE during the five-year period. Conclusions: Infections with ESKAPE pathogens are now a problem that can no longer be overlooked in Dentistry. Based on results of this study, ESKAPE pathogens were highly associated with post-operative or opportunistic infections. Clinicians should be careful about these antibiotic resistant pathogens and use appropriate antibiotics to patients while having dental treatments.
