The large defect of oral and maxillofacial region doesn't only affect the function and aesthetics but also has an adverse impact on patients' psychology. The traditional way to restore the defects are limited by donor site and secondary trauma. In recent years,the oral mucosal tissue engineering has developed rapidly and provides a new solution for craniofacial reconstruction. Tissue-engineered oral mucosa is an ideal substitute of oral mucosa. It can be used in clinical settings and in vitro experiments. This articles review the recent advances in tissue-engineered oral mucosa and its applications...

PURPOSE: Microsurgical reconstruction in a vessel-depleted neck is a challenge due to the lack of reliable vessels in or nearby the host site. The use of the internal thoracic pedicle (ITP) by rib section or sparring is a limited option due to the small length of the pedicle of some flaps. However, in cardiac surgery, the internal thoracic artery (ITA) is widely used for myocardial revascularization, providing a long and versatile pedicle. We aimed at determining precise anatomical bases for the use of the ITP, approached by sternotomy and rerouted in the neck, as recipient vessels for free-flap facial reconstructions...

Maxillofacial defects are complex lesions stemming from various etiologies: accidental, congenital, pathological, or surgical. A bone graft may be required when the normal regenerative capacity of the bone is exceeded or insufficient. Surgeons have many options available for bone grafting including the "gold standard" autologous bone graft. However, this approach is not without drawbacks such as the morbidity associated with harvesting bone from a donor site, pain, infection, or a poor quantity and quality of bone in some patient populations...

OBJECTIVE: Cognitive impairment after intensive care unit (ICU) admission is becoming increasingly recognized. High-dose deep sedation has been suggested to play an important role in the development of cognitive impairment. However, the impact of heavy sedation as a single cause in the development of cognitive impairment in ICU patients remains unclear. In this study we investigated whether a three-day deep sedation protocol could reduce cognitive function in mechanically ventilated non-critical patients...

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...

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...

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...

The care and the management of the healing of difficult wounds at the level of the skull-facial face many problems related to patient compliance and the need to perform multiple dressings, with long periods of healing and, occasionally, a very long hospitalisation period. The introduction and evolution of negative pressure wound therapy (NPWT) in the treatment of difficult wounds has resulted in better healing, with a drastic reduction in terms of time and biological costs to the patient and cost to the health care system...

This protocol describes the use of a newly developed external fixator for distraction osteogenesis in a rat femoral model. Distraction osteogenesis (DO) is a surgical technique leading to bone regeneration after an osteotomy. The osteotomized extremities are moved away from each other by gradual distraction to reach the desired elongation. This procedure is widely used in humans for lower and upper limb lengthening, treatment after a bone nonunion, or the regeneration of a bone defect following surgery for bone tumor excision, as well as in maxillofacial reconstruction...

OBJECTIVE: Postoperative pneumonia (POP) is common and results in prolonged hospital stays, higher costs, increased morbidity and mortality. However, data on the incidence and risk factors of POP after oral and maxillofacial surgery are rare. This study aims to identify perioperative risk factors for POP after major oral cancer (OC) surgery. METHODS: Perioperative data and patient records of 331 consecutive subjects were analyzed in the period of April 2014 to March 2016...

Regular monitoring of free flaps is essential after microvascular free tissue transfer, but the frequency and duration of the observations vary between units and there is no consensus nationally. Best practice can be informed by the feedback of patients, but as we know of no such studies, we did a cross-sectional survey of a consecutive group of patients after free tissue transfer to find out what they thought about monitoring. We designed a study-specific questionnaire after consultation with the patient and carer forum, and sent it to 150 patients who had had free tissue transfer in the maxillofacial department at Aintree University Hospital during 2015 and 2016...
