BACKGROUND: All clinicians are aware of the difficulty of installing a dental implant in posterior maxilla because of proximate position of maxillary sinus, insufficient bone width, and lower bone density. This study is to examine which factors will make the implantation in the posterior maxilla more difficult, and which factors will affect the postoperative implant stability in this region. METHODS: Five hundred seventy-three fixtures on the maxilla posterior were included for this study from all the patients who underwent an installation of the dental implant fixture from January 2010 to December 2014 at the Department of Oral and Maxillofacial Surgery in Pusan National University Dental Hospital (Yangsan, Korea)...

OBJECTIVES: The aim of this study is to evaluate the effectiveness of decompression according to reduction parameters by measuring cystic volume changes using computed tomography (CT). STUDY DESIGN: We chose patients who had undergone decompression for a cystic lesion of the jaw at the Department of Oral and Maxillofacial Surgery in our dental hospital between 2006 and 2015. All patients had been examined by CT before and after decompression. We measured the volume of cystic lesions using the threshold method and evaluated the volumetric changes after decompression according to various parameters...

BACKGROUND: After sinus surgery, patients are commonly instructed to irrigate with saline irrigations with their heads over a sink and noses directed inferiorly (nose-to-floor). Although irrigations can penetrate the sinuses in this head position, no study has assessed whether sphenoid sinus penetration can be improved by irrigating with the nose directed superiorly (nose-to-ceiling). The purpose of this study was to use a validated computational fluid dynamics (CFD) model of sinus irrigations to assess the difference in sphenoid sinus delivery of irrigations after irrigating in a nose-to-floor vs nose-to-ceiling head position...

BACKGROUND: A fracture of root canal instruments, with a fractured piece protruding beyond the apex, is a troublesome incident during an endodontic treatment. Locating and retrieving them represents a challenge to maxillofacial surgeons because it is difficult to access due to the proximity between the foreign body and vital structures. Although safe and accurate for surgery, radiographs and electromagnetic devices do not provide a precise three-dimensional position. In contrast, computer-aided navigation provides a correlation between preoperatively collected data and intraoperatively encountered anatomy...

PURPOSE: Nasotracheal intubation is a widely performed technique to facilitate anesthesia induction during oral, dental, and maxillofacial surgeries. The technique poses several risks not encountered with oropharyngeal intubation, most commonly epistaxis due to nasal mucosal abrasion. The purpose of this study was to test whether the use of the Parker Flex-Tip™ (PFT) nasal endotracheal tube (ETT) with a posterior facing bevel reduces epistaxis when compared with the standard nasal RAE ETT with a leftward facing bevel...

PURPOSE: The advent of microvascular free tissue transfer has provided the reconstructive surgeon with an enormous array of treatment options for reconstruction of large head and neck defects. However, when indicated by defect size, the need for more than 1 flap not only increases surgical complexity but also patient morbidity. The combination of the anterolateral thigh (ALT) flap and the tensor fascia latae (TFL) flap can be used to reconstruct such complex head and neck defects, thereby minimizing any additional morbidity that would be imposed by an additional flap harvest site...

BACKGROUND: A principal reason for flap compromise in oral and maxillofacial head and neck surgery, and failure of a free flap transfer, is thrombosis of a drainage vein such as the internal jugular vein. This study characterized flap compromise caused by internal jugular vein thrombosis after a free flap transfer, and its management. PATIENTS AND METHODS: A retrospective clinical study was conducted of 306 consecutive microvascular free flaps performed for 305 patients with head and neck cancer from March 2003 to March 2013 at the Department of Oral and Maxillofacial Surgery at Beijing Stomatological Hospital, Capital Medical University...

Medication-related osteonecrosis of the jaws (MRONJ) is an adverse side effect of several drug therapies, including bisphosphonates (BPs). Osteonecrosis of the jaw specifically related to BP therapy is usually referred to using the acronym BRONJ. However, no consensus has yet been reached regarding the most appropriate management of BRONJ. The greatest success rates have been recorded with surgical removal of necrotic bone. In particular, erbium:yttrium-aluminum-garnet (Er:YAG) laser-assisted surgery has shown significantly better results than conventional surgical approaches...

A 72-year-old male (height: 160 cm, weight: 53 kg) was scheduled to undergo left renal and male with ans uterine tract resection. The patient had previously undergone right radical maxillofacial surgery with orbital exenteration 14 years before the present operation to treat squamous cell carcinoma of the right maxillary sinus, with tumour invasion to the orbital floor. An anaesthesiologist encountered difficulty in performing mask ventilation during the induction of anaesthesia in the patient, despite a good mask fit on the face, because the adhesive tape around the orbit had moved...

BACKGROUND: Loosening of screws is a common problem in orthopedic and maxillofacial surgery. Modifying the implant surface to improve the mechanical strength of screws has been tried and reported. We developed screws coated with fibroblast growth factor-2 (FGF-2)-apatite composite layers. We then showed, in a percutaneous external fixation model, that this composite layer had the ability to hold and release FGF-2 slowly, thereby reducing the risk of pin tract infection of the percutaneous external fixation...

BACKGROUND: Fibrin sealants are used in different types of surgery to prevent the accumulation of post-operative fluid (seroma) or blood (haematoma) or to arrest haemorrhage (bleeding). However, there is uncertainty around the benefits and harms of fibrin sealant use. OBJECTIVES: To systematically review the evidence on the benefits and harms of fibrin sealants in non-emergency surgery in adults. DATA SOURCES: Electronic databases [MEDLINE, EMBASE and The Cochrane Library (including the Cochrane Database of Systematic Reviews, the Database of Abstracts of Reviews of Effects, the Health Technology Assessment database and the Cochrane Central Register of Controlled Trials)] were searched from inception to May 2015...

INTRODUCTION: In maxillofacial surgery, the simplest procedure that we perform is dental extraction. However, this simple procedure is challenged by the patient's poor medical condition. We generally use local anesthesia in combination with adrenaline; however, as we come across patients with diabetes mellitus and cardiovascular diseases who seek dental extraction, we need to be doubly cautious while using adrenaline. In this study, we intend to compare the effects of local anesthesia with adrenaline and local anesthesia without adrenaline on hemodynamic changes (blood pressure and pulse rate) and random blood sugar levels...
