A case of large glandular odontogenic cyst of the mandible is presented in which the panoramic radiograph also demonstrated a soft tissue lesion consistent with carotid aneurysm. CT confirmed the bucco-lingual extent of the mandibular lesion and the presence of a soft tissue lesion consistent with an aneurysm of the internal carotid artery. CT angiography, MR angiography and US were used to rule out a carotid artery aneurysm prior to surgery of the mandibular lesion.Dentomaxillofacial Radiology (2002) 31, 291–298. doi:10.1038/sj.dmfr.4600716 [ABSTRACT FROM AUTHOR]

Purpose: Self-inflicted gunshot wounds to the face are one of the most challenging clinical scenarios encountered by oral and maxillofacial surgeons. Knowledge is lacking regarding which factors might influence survival after these devastating injuries, especially pertaining to psychiatric history and substance use. The purpose of the present study was to evaluate the risk factors that might influence the survival of subjects with self-inflicted gunshot wounds to the face., Materials and Methods: A retrospective cohort study was designed to analyze the data from subjects presenting to the University of Louisville Trauma Center with self-inflicted gunshot wounds to the face from February 2010 to September 2019. The predictor variables included demographic (eg, age, gender, race), medical and psychiatric history, and toxicology test results. The primary outcome variable was death before hospital discharge. Descriptive, bivariate, and logistic regression models were computed., Results: The sample included 120 subjects, with an age range of 16 to 85 years old (average age, 43.5 years); 90.8% were male, and 56.7% had survived their suicide attempt. Of the 120 patients, 35% had a history of depression, 23.3% tested positive for benzodiazepines, and 33% had a social history positive for smoking, alcohol use, and/or drug use. Depression was the single largest predictor of mortality. Patients with depression were significantly more likely to survive their injuries than were patients without depression (odds ratio, 0.230; P = .003). The presence of benzodiazepines in toxicology tests was also a significant predictor of mortality (odds ratio, 0.297; P = .018); patients testing positive were more likely to survive than were patients with negative test results or positive test results for other drugs., Conclusions: Subjects who attempt suicide via self-inflicted gunshot wounds to the face were more likely to survive their injury if they had a reported history of depression or test results positive for a benzodiazepine., (Published by Elsevier Inc.)

This case report describes an unusual odontogenic carcinoma, which was detected during routine periodontal examination. The lesion occurred in a dentigerous cyst associated with an impacted third molar in an otherwise asymptomatic 66-year-old male patient. The impacted tooth and lesion were excised based on evidence of radiographic change and clinical findings. An unusual histopathologic presentation is reported. The treatment provided for this tumor and the management of impacted teeth is reviewed.

Background and Objectives: Since the introduction of antibiotics in the late 1940s, open reduction and internal fixation (ORIF) gradually replaced various dental splints and devices as a means of providing additional reduction and fixation of mandibular fractures. Stainless steel wire has been recently replaced by plate-and-screw fixation. When properly utilized, this method provides convalescent function without maxillomandibular fixation (MMF). The purpose of this article is to review the evolution of small versus large plate fixation of mandibular fractures., Methods and Materials: In the context of reports in the literature and 26 years of clinical experience, the authors review the types of mandibular rigid fixation, healing of fractures, morbidity of fracture repair, indications for rigid fixation, and evolution of techniques of treatment., Results And/or Conclusions: Although numerous devices and techniques--bone clamps, intra- and extramedullary K-wires, metallic mesh, and other means--have been used and abandoned, modern plate and screw systems, if not the standard of care, have become widely accepted and used.

The mandible is often fractured during maxillofacial trauma because of its prominence within the facial skeleton and the fact that it is a favorite target in interpersonal violence. Treatment of mandibular fractures has made significant advances over the years due to the study of biomechanical principles, advancements in biomaterials and instrumentation and scientifically based research of treatment outcomes. This article will review the principles and philosophy of AO/ASIF techniques as applied to treatment of mandible fractures. Representative cases of different mandible fractures and their treatment will reinforce the clinical application of rigid fixation techniques.

Myositis ossificans traumatica of the masseter muscle is uncommon. The condition is benign and results in reactive heterotopic bone formation, usually producing limitation of opening of the jaws. Radiographic and microscopic examination can confirm the diagnosis. Treatment of myositis ossificans traumatica of the masseter muscle is surgical, with other modalities used when occurring in other muscles of the body.

This study evaluated the safety and efficacy of combined treatment with epsilon-aminocaproic acid or tranexamic acid and monoclonal antibody purified factor IX (MAb factor IX) for prophylaxis against bleeding in eight hemophilia B patients undergoing nine dental extraction procedures. All patients achieved excellent hemostasis without clinical evidence of thrombosis. There were no significant changes in hemoglobin or hematocrit or in markers of hemostatic system activation (prothrombin fragment F1+2, fibrinopeptide A, and fragment B beta 15-42) after surgery. Thus, a highly purified factor IX concentrate and antifibrinolytic therapy can be effectively and safely combined in hemophilia B patients undergoing dental extractions.

Endosseous implant placement is generally considered to be contra-indicated in patients undergoing chemotherapy for the treatment of cancer. A case is presented where a patient was diagnosed with cancer and began chemotherapy four weeks after endosseous implants were placed. The impact of chemotherapeutic agents on endosseous implant acceptance as well as upon oral tissue is examined.
