Intraoperative bradycardia (IOB) is one of the most common cardiac arrhythmias observed in clinical anaesthetic practice. Controlled hypotension, as a strategy of lowering patient's blood pressure during anesthesia has been practiced for decades in head and neck surgery. The aim of our study was to determine the incidence and the risk factors for intraoperative bradycardia in maxillofacial, ear, nose and throat surgery, as well as to determine whether controlled hypotension affects the occurrence of IOB. The retrospective study included 2304 patients who underwent maxillofacial, ear, nose or throat surgery...

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)...

Trigeminocardiac reflex is a sudden physiologic response due to mechanical manipulation of any of the branches of trigeminal nerve. Trigeminocardiac reflex occurs due to pressure effect or stretching of trigeminal nerve which causes fall in blood pressure and decrease in heart rate. In this reflex arc, the trigeminal nerve serves as afferent pathway and vagus nerve, which is cardio inhibitory in nature, serves as efferent pathway. Two episodes of trigeminocardiac reflex during maxillofacial trauma surgery is not a common phenomenon...

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...

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...
