OBJECTIVE: Resection of posteriorly located oral squamous cell carcinomas (OSCCs) remains challenging for head and neck surgeons. However, several surgical techniques, such as lip and mandibular splitting, as well as submental "visor drop-down" of intraoral soft tissues, have been proposed for this purpose. Merrick et al. suggested that a pedicled genial drop-down surgical approach should be used to resect dorsally located OSCCs. Our study investigated patient outcomes following this surgical procedure, as no previous study has analyzed long-term follow-up data...

PURPOSE: Zygomaticomaxillary complex (ZMC) fractures are frequent in facial trauma; only fractures of the mandible are more common. Although the frequency of these fractures is geographically consistent, the aetiology differs widely among countries and even regions. Differences in socio-economic status and the ageing population seem to be two causes. This retrospective epidemiological study evaluates patients who were surgically treated for ZMC fractures at a Swiss university clinic. MATERIALS AND METHODS: This study included 471 patients who were surgically treated for ZMC fractures in an oral and maxillofacial surgery clinic at a Swiss university hospital between January 2004 and December 2012...

INTRODUCTION: Osteosarcoma is an aggressive primary bone tumor composed of connective tissue cells directly producing osteoid and bone. Prosthetic rehabilitations in post-oncological patients after bone reconstruction are not substantially different than those of patients affected by severe atrophy of upper or lower jaw after bone reconstruction. The treatment for patients with a malignant neoplasia of the oral cavity requires multidisciplinary approach by a team of different specialists that follow the patient through the phases of diagnosis, therapy and oral rehabilitation...

Endoscope-assisted oral and maxillofacial surgeries have been applied to the resection of tumors with minimal invasion and good cosmetic outcomes. However, with regard to endoscope-assisted resection of nonneoplastic space-occupying lesion (NSOL) in oral and maxillofacial areas which differ from tumors in treatment, there are no systematic reports. Therefore the advantages and limitations of the endoscopy-assisted approach (EAA) in resection of NSOL remain unclear. In this novel study we describe endoscope technique for resection of NSOL in face and submandibular areas and compare the feasibility and effectiveness of EAA with external approach (EA)...

Few studies have examined the practice characteristics of dentist anesthesiologists and compared them to other anesthesia providers. Using outcomes from the National Anesthesia Clinical Outcomes Registry and the Society for Ambulatory Anesthesia Clinical Outcomes Registry for dental/oral surgery procedures, we compared 7133 predominantly office-based anesthetics by dentist anesthesiologists to 106,420 predominantly operating room anesthetics performed by physician anesthesia providers. These encounters were contrasted with 34,191 previously published encounters from the practices of oral and maxillofacial surgeons...

Fasting before general anesthesia aims to reduce the volume and acidity of stomach contents, which reduces the risk of regurgitation and aspiration. Prolonged fasting for many hours prior to surgery could lead to unstable hemodynamics, however. Therefore, preoperative oral intake of clear fluids 2 hours prior to surgery is recommended to decrease dehydration without an increase in aspiration risk. In this study, we investigated the body fluid composition and hemodynamics of patients undergoing general anesthesia as the first case of the day versus the second subsequent case...

Many maxillofacial patients have serious short, medium, or long-term problems, as well as having to make informed decisions about often life-changing interventions. Validated comprehensive information, at the right time and the right level for a diverse group of users (patients, carers, and professionals), is vital if patients are to make a serious contribution to their treatment. We describe the development of an online resource for this purpose. Maxfacts.uk aims to cover every aspect of oral and maxillofacial surgery and care, from neck dissection and ballistic wounds to physiotherapy and texture-modified foods...

Introduction Communication within the doctor-patient relationship is complex due to a variety of reasons; a patient's understanding may not correspond with the clinician's vocabulary, resulting in misunderstanding, anxiety and ill-informed decision making. We investigated the understanding of terminology commonly used in oral and maxillofacial surgery and oral medicine clinics.Methods We investigated patients' understanding using a questionnaire-based study in the out-patient setting. Age, gender, first language and highest educational level were recorded...

Lip cancer represents between 12-15% of all oral cavity cancers; 95% affect the lower lip. The main objectives in lip reconstruction after tumoral mass resection are functionality and esthetics. We present the case of an 81-year-old male with a past medical history of squamous cell carcinoma of the maxilla. The patient consults with the Maxillofacial Surgery Department due to a hypertrophic lesion in the left oral commissure. The defect is considered intermediate in size (between 50% and 2/3). For reconstruction of the lip, a classical rotation flap (Estlander flap) is used together with a myomucosal flap, which is both innervated and expandable...

Cementoblastoma is a benign odontogenic neoplasm accounting for less than 0.69%-8% of all odontogenic tumours and is characterised by the presence of sheets of cementum-like tissue demonstrating large number of reversal lines. It shows an unlimited growth potential and a recurrence rate as high as 37.1%. It most commonly affects the permanent mandibular molars. This paper presents the third reported case of cementoblastoma affecting the deciduous maxillary posterior dentition. A 12-year-old male patient reported to the Department of Oral and Maxillofacial Pathology with a chief complaint of pain and swelling in relation to the deciduous maxillary left second molar...
