Titanium Lag Screw Versus Miniplate Fixation in the Treatment of Anterior Mandibular Fractures.

J Oral Maxillofac Surg 2019 Jan 15. Epub 2019 Jan 15.

Resident and Postdoctoral Researcher, Departments of Periodontics and Endodontics and Oral Biology, School of Dental Medicine, SUNY Buffalo, Buffalo, NY.

Purpose: The use of plates for open reduction and internal fixation of mandibular fractures has become a widely accepted method in the past 3 decades. However, the anterior mandible is well suited to lag screw fixation owing to the thickness of its bony cortices. Hence, the purpose of the present study was to comparatively evaluate clinical outcomes of fixation using lag screws and miniplates in anterior mandibular fractures. Read More

Touch Imprint Cytology: Can It Serve as an Alternative to Frozen Section in Intraoperative Assessment of Cervical Metastasis in Oral Squamous Cell Carcinoma?

J Oral Maxillofac Surg 2019 Jan 14. Epub 2019 Jan 14.

Professor, Department of Oral & Maxillofacial Surgery, Sharad Pawar Dental College, Datta Meghe Institute of Medical Sciences, Wardha, India.

Purpose: The purpose was to assess the diagnostic accuracy of touch imprint cytology (TIC) compared with frozen section (FS) analysis as an intraoperative diagnostic tool to assess nodal metastasis in oral squamous cell carcinoma.

Materials And Methods: We intraoperatively assessed 38 patients undergoing neck dissection for oral squamous cell carcinoma, wherein a total of 248 nodes were sectioned and subjected to TIC and, subsequently, FS analysis and were finally submitted to the gold-standard histopathologic examination. The sensitivities, specificities, positive predictive values (PPVs), and negative predictive values (NPVs) of TIC and FS analysis for the detection of metastasis in the cervical nodes were determined with the corresponding 95% confidence intervals.

Surgical Management of Mandibular Subcondylar Fractures Under Local Anesthesia: A Proposed Protocol.

J Oral Maxillofac Surg 2019 Jan 14. Epub 2019 Jan 14.

Junior Resident, Department of Oral & Maxillofacial Surgery, King George's Medical University, Lucknow, India.

Epstein-Barr Virus-Positive Mucocutaneous Ulcer Mimicking Peri-Implantitis in a Patient With Systemic Lupus Erythematosus.

J Oral Maxillofac Surg 2019 Jan 5. Epub 2019 Jan 5.

Professor of Oral Pathology, Department of Stomatology, Public Oral Health and Forensic Dentistry, School of Dentistry of Ribeirão Preto, University of São Paulo, Ribeirão Preto, Brazil.

Epstein-Barr virus-positive mucocutaneous ulcer (EBVMCU) is characterized by cutaneous and/or mucosal ulcers in patients receiving immunosuppressive medication or with age-related immunosenescence. Its microscopic appearance often leads to a diagnostic challenge, sometimes mimicking an overt lymphoma. A 47-year-old woman, with a previous diagnosis of systemic lupus erythematosus, was referred for evaluation of a gingival ulcer, present for about 2 months and located in the maxillary peri-implant mucosa around implants, resembling peri-implantitis.

Precision of Simultaneous Guided Dental Implantation in Microvascular Fibular Flap Reconstructions With and Without Additional Guiding Splints.

J Oral Maxillofac Surg 2018 Dec 31. Epub 2018 Dec 31.

Consultant, Department of Oral and Cranio-Maxillofacial Surgery, University Hospital Zurich, Zurich, Switzerland.

Purpose: Dental rehabilitation in patients receiving free flap reconstructive surgery on the mandible or maxilla is an important part of bringing patients back to normality in both a physical and psychological way. It is therefore important to be able to do this in the fastest way possible. Virtual preplanned reconstructions of jaws with implants placed simultaneously are a good way to expedite this process and have the advantage of allowing true backward planning to achieve bone placement where it prosthetically needs to be.

A New Orbito-Zygomatic Complex Reconstruction Technique Using Computer-Aided Design and Manufacturing-Assisted Harvest of Autologous Calvarial Bone in Cases of Orbito-Zygomatic Benign Tumor.

J Oral Maxillofac Surg 2018 Dec 31. Epub 2018 Dec 31.

Professor, University of Lille, Department of Oral and Maxillofacial Surgery, CHU Lille, and INSERM U1008, Controlled Drug Delivery Systems and Biomaterials, Lille, France.

The orbito-zygomatic complex (OZC) includes several key structures, and its destruction leads to the impairment of functional activities such as nutrition, communication, nasal support, and vision. Management of benign tumors of the OZC is therefore a surgical challenge because of the necessity for reconstruction of these elements. Autogenous bone is considered the gold standard for reconstruction. Read More

Assistant Professor, Unit of Oral and Maxillofacial Surgery, Department of Biomedical and Neuromotor Science, University of Bologna, Bologna, Italy.

Purpose: The extraction of third molars is the most common surgical procedure performed in the oral cavity. Coronectomy is a surgical protocol to reduce the risk of neurologic lesions to the inferior alveolar nerve (IAN). We evaluated early (up to 1 month) and late (from 2 to 60 months) postoperative complications. Read More

Unusual Supernumerary Teeth and Treatment Outcomes Analyzed for Developing Improved Diagnosis and Management Plans.

J Oral Maxillofac Surg 2018 Dec 27. Epub 2018 Dec 27.

Assistant Professor, Division of Oral and Maxillofacial Surgery, Department of Stomatology, Institute of Oral Medicine, National Cheng Kung University Medical College and Hospital, Tainan, Taiwan. Electronic address:

Purpose: Supernumerary teeth (SNTs) are teeth or tooth-like structures that have erupted or might erupt in addition to the 20 primary or 32 permanent teeth. The simultaneous presentation of multiple SNTs, syndrome-related multiple SNTs, SNTs inside the maxillary sinus and treatment outcomes were analyzed to develop improved diagnosis and management plans.

Patients And Methods: This retrospective study reviewed the medical records of National Cheng Kung University Hospital patients who had undergone surgical intervention with general anesthesia between February 2014 and September 2018; analyzed panoramic radiographs and cone beam computed tomography scans of their multiple SNTs; and used descriptive statistics to discuss treatments and relative complications, especially of unusual SNTs.

The "European Mandibular Angle" Research Project: The Epidemiologic Results From a Multicenter European Collaboration.

J Oral Maxillofac Surg 2018 Dec 27. Epub 2018 Dec 27.

Full Professor, Department of Oral and Maxillofacial Surgery/Pathology, VU University Medical Center and Academic Centre for Dentistry Amsterdam, Amsterdam, The Netherlands.

Purpose: The aim of this study was to analyze the demographic variables and causes and characteristics of mandibular angle fractures managed at several European departments of maxillofacial surgery.

Materials And Methods: This study was based on a multicenter systematic database that allowed the recording of data from all patients with mandibular angle fractures between January 1, 2013, and December 31, 2017. The following data were recorded: gender, age, etiology, side of angle fracture, associated mandibular fractures, presence of third molar, intermaxillary fixation, and osteosynthesis. Read More

Rate of Submandibular Gland Involvement in Oral Squamous Cell Carcinoma.

J Oral Maxillofac Surg 2018 Dec 22. Epub 2018 Dec 22.

Professor, Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology, National Engineering Laboratory for Digital and Material Technology of Stomatology, Beijing Key Laboratory of Digital Stomatology, Beijing, China. Electronic address:

Purpose: Whether the submandibular gland (SMG) can be preserved during neck dissection in the surgical treatment of oral squamous cell carcinoma (OSCC) is controversial. This study investigated the SMG involvement rate and provides a basis for preserving the SMG during neck dissection in appropriate cases of OSCC.

Materials And Methods: A comprehensive systematic review was conducted on the PubMed and MEDLINE, Embase, and Cochrane Library databases for studies on SMG involvement in OSCC published before December 2017 with a data analysis technique. Read More

Clear Aligner Orthognathic Splints.

J Oral Maxillofac Surg 2018 Dec 22. Epub 2018 Dec 22.

Resident in Orthodontics and MSc Candidate, University of Toronto, Toronto, ON, Canada.

Orthodontic treatment has been transformed by the introduction and overwhelming adoption of clear aligner therapy (CAT). Many patients are demanding esthetic and metal-free treatment alternatives, including those requiring orthognathic surgery (OGS), to correct their dentofacial deformities. The adoption of performing OGS for CAT has been cautious and challenging for many reasons. Read More
