OBJECTIVE: To evaluate whether current oral and maxillofacial surgery (OMS) residents are receiving adequate training and experience to perform specific surgical procedures and anesthesia for pediatric patients. STUDY DESIGN: A 17-question survey was sent electronically to fellows of the American Academy of Craniomaxillofacial Surgeons. Descriptive data for individual surgeons, their associated residency programs, and the quantity of specific pediatric procedures they performed were collected...

INTRODUCTION: 3D-printing seems to have more and more applications in maxillofacial surgery (MFS), particularly since the release on the market of general use 3D-printers several years ago. The aim of our study was to answer 4 questions: 1. Who uses 3D printing in MFS and is it routine or not? 2. What are the main clinical indications for 3D-printing in MFS and what are the kinds of objects that are used? 3. Are these objects printed by an official medical device (MD) manufacturer or made directly within the department or the lab? 4...

AIM: The purpose of this study was to review patient outcomes from surgical reconstruction of isolated orbital fractures, performed by the Auckland District Health Board (ADHB) Oral and Maxillofacial Surgery service (OMFS), from 2010 to 2015. In particular, we wished to assess titanium as an orbital reconstructive material and compare outcomes with the international literature. METHOD: Hospital records for 103 adults (>18 years old) who underwent repair of isolated orbital fractures by the OMFS department at Middlemore Hospital, between 2010 and 2015, were reviewed...

INTRODUCTION: Presently, during the surgical treatment of the patients in maxillofacial surgery, one can use various medical implants. Moreover custom made implants are being used. Replacements may be fitted to the structure and shape of the human skull owing to CAD/CAM (custom aided design/manufacture) called customized implants. This study was aimed to report for the first time clinical material from which custom implants, using two different techniques, were manufactured to reconstruct the temporomandibular joint (TMJ)...

RATIONALE: Precise bony reduction and reconstruction of optimal contour in treating comminuted mandibular fractures is very difficult using traditional techniques and devices. The aim of this report is to introduce our experiences in using virtual surgery and three-dimensional (3D) printing technique in treating this clinical challenge. PATIENT CONCERNS: A 26-year-old man presented with severe trauma in the maxillofacial area due to fall from height. DIAGNOSIS: Computed tomography images revealed middle face fractures and comminuted mandibular fracture including bilateral condyles...

PURPOSE: Measurement of the root surface area (RSA) is important in periodontal treatment and for the evaluation of periodontal disease as a risk factor for systemic disease. The aim of this study was to measure the RSA at 6 mm below the cementoenamel junction (CEJ) using the Mimics software (Materialise, Leuven, Belgium). METHODS: We obtained cone-beam computed tomography (CBCT) data from 33 patients who had visited the Department of Oral and Maxillofacial Radiology of Dankook University Dental Hospital...

The oral and maxillofacial region is rich in blood, and it is often difficult to stop bleeding during the operation of maxilla. Nitroglycerin is one of the most commonly used antihypertensive drugs in our hospital. We observed the effect of controlled hypotension in patients with maxillary resection. In group N, the patients had different degrees of tachycardia after using nitroglycerin only. In addition, nitroglycerin has the characteristics of rapid drug resistance. A combined reversed temporal muscle flap and random forehead flap technique was performed successfully to reconstruct the large defect after ipsilateral maxillectomy and orbit evisceration...

Danmei Luo, Qiguo Rong, Quan Chen
Reconstruction of segmental defects in the mandible remains a challenge for maxillofacial surgery. The use of porous scaffolds is a potential method for repairing these defects. Now, additive manufacturing techniques provide a solution for the fabrication of porous scaffolds with specific geometrical shapes and complex structures. The goal of this study was to design and optimize a three-dimensional tetrahedral titanium scaffold for the reconstruction of mandibular defects. With a fixed strut diameter of 0...

BACKGROUND: The aim of this investigation was to evaluate the length, thickness, sagittal and transvers angulations and the morphological variations of the stylohyoid complex (SHC), to assess their probable assosiations with age and gender, and to investigate the prevalence of it in a wide range of a Turkish sub-population by using cone beam computed tomograph (CBCT), thereby conducting dentist and maxillofacial surgeons. METHODS: The CBCT images of the 1000 patients were evaluated retrospectively...

BACKGROUND: The scope of microvascular tissue transfer in the Head and Neck reaches from coverage of simple soft tissue defects to complex 3-D reconstructions using multiple or chimeric flaps. This paper summarises the presentation given at the Congress of the French Society of Oral and Maxillofacial Surgery in Marseille 2017. It was the aim of our work to add further elements to this wide spectrum of reconstructive possibilities. METHODS: For patients with small intraoral soft tissue defects in whom the use of a radial forearm flap would not be justified because of its donor site morbidity, but who nevertheless would take a benefit from a small free flap, we used mini-perforator flaps from the lower leg...

Objective: To explore a digital negative molds technique based on three-dimensional (3D) printing to assist in the manufacture of maxillofacial prostheses, and to improve the deficiency of the current clinical treatment. Methods: Seventeen patients with maxillofacial defects (including nasal defects, orbital defects, cheek defects, auricle defect) were scanned by means of facial optical scanning and computer tomography (CT). The 3D models were then reconstructed and global registration was made to merge the reconstructed models into a new digital model for 3D design...

S M Balaji, Preetha Balaji
BACKGROUND: Temporomandibular joint (TMJ) ankylosis is a situation in which the mandibular condyle is fused to the glenoid fossa by bone or fibrous tissue. The management of TMJ ankylosis has a complicated chore, and it is challenging for the maxillofacial surgeon because of technical hitches and high rate of reankylosis. Costochondral graft (CCG) is a common treatment modality for TMJ ankylosis. One of disadvantages of CCG is unpredictability of growth pattern and risk of overgrowth...

BACKGROUND AND PURPOSE: Dose reduction on CT scans for surgical planning and postoperative evaluation of midface and orbital fractures is an important concern. The purpose of this study was to evaluate the variability of various low-dose and iterative reconstruction techniques on the visualization of orbital soft tissues. MATERIALS AND METHODS: Contrast-to-noise ratios of the optic nerve and inferior rectus muscle and subjective scores of a human cadaver were calculated from CT with a reference dose protocol (CT dose index volume = 36...

REVIEW
Azizollah Khodakaram-Tafti, Davood Mehrabani, Hanieh Shaterzadeh-Yazdi
The purpose of this review is to have an overview on the applications on the autologous fibrin glue as a bone graft substitute in maxillofacial injuries and defects. A search was conducted using the databases such as Medline or PubMed and Google Scholar for articles from 1985 to 2016. The criteria were "Autograft," "Fibrin tissue adhesive," "Tissue engineering," "Maxillofacial injury," and "Regenerative medicine." Bone tissue engineering is a new promising approach for bone defect reconstruction. In this technique, cells are combined with three-dimensional scaffolds to provide a tissue-like structure to replace lost parts of the tissue...
