Magnetic detection of sentinel nodes in oral squamous cell carcinoma by means of superparamagnetic iron oxide contrast.

The aim was to evaluate sentinel node detection capacity by means of a magnetic probe in 11 patients with oral squamous cell carcinoma at stages T1-T2 received submucosal injections of a superparamagnetic iron oxide contrast agent (SPIO). A magnetic probe was used for sentinel node biopsy. The use of SPIO and magnetic probes in the early stages of oral cancer may offer an alternative to conventional radioisotope techniques and/or elective neck dissection.

Polymethyl Methacrylate Custom-Made Prosthesis: A Novel Three-Dimension Printing-Aided Fabrication Technique for Cranial and/or Orbital Reconstruction.

Background: Over the years, many materials have been used in orbital reconstruction and cranioplasty. Among the materials in current use, polymethyl methacrylate (PMMA) offers a high degree of compatibility with human tissue.

Objective: This work describes a new, custom-made, 3D printing-aided, prosthetic fabrication process for orbital and/or cranial reconstruction using PMMA.

Reconstruction of a Compound Oromandibular Defect by Means of Chimeric Scapular-Parascapular Free Flap Assisted by Virtual Surgical Planning.

Background: Reconstruction of an oromandibular defect presents a considerable surgical challenge. But since the advent of microvascularized free flap reconstructive surgery, outcomes have improved significantly so that today almost any defect may be reconstructed. Recently, virtual surgical planning has reduced surgical time, the morbidity associated with surgery, and surgical precision.

Piezosurgery for Treatment of Large Recurrent Mandibular Osteoma.

Background: Osteomas are infrequent benign bone tumors of uncertain etiology. They are usually situated at extremities and their occurrence in the jaws is relatively rare. There are 3 types of osteoma: central, peripheral, and extraskeletal.

Reconstruction of Liposarcoma Resection Defect With a Made-to-Measure Polyethylene Prosthesis Using Three-Dimensional Digital Technology.

Background: Liposarcoma is considered one of the most frequently occurring tumors of the soft tissues, representing 17% to 30% of all mesenchymal cell tumors. It is less common in the head and neck representing <10% of tumors in this region. The reconstruction of defects derived from resection of these tumors presents a surgical challenge.

Sentinel node biopsy versus elective neck dissection. Which is more cost-effective? A prospective observational study.

Objective: The aim of this prospective not randomized observational study was to determine the costs and outcomes of sentinel lymph node biopsy (SNB) vs elective neck dissection (END) among patients with early oral squamous cell carcinoma (OSCC).

Materials And Methods: Seventy-three consecutive patients were divided according to neck staging method. Patients took the decision themselves after receiving detailed information of both suggested treatment tools.

DNA aneuploidy as a topographic malignant transformation pattern in a pleomorphic adenoma of long-term evolution: a case report.

Introduction: We present a case of long-term evolution of a submandibular pleomorphic adenoma. There is little information about topographic malignant transformation patterns of pleomorphic adenomas.

Case Presentation: We extensively analyze a giant submandibular mixed tumor of 25-year evolution in a 57-year-old Caucasian woman.

Oroantral communications. A retrospective analysis.

Objective: To analyze characteristics, clinical evolution and surgical techniques of oroantral communication (OAC).

Study Design: We included all patients operated at the University Central Hospital (Oviedo, Spain) between 1996 and 2007. The variables assessed were age, sex, medical history, OAC size, sinus disease, surgical technique, duration of hospitalization and post-surgical evolution.

Synchronous oral squamous cell carcinoma and extramedullary plasmacytoma of the tonsil.

Extramedullary plasmacytoma (EP) is characterized by a neoplastic proliferation of plasma cells in a soft tissue site and arises particularly in the head and neck region. We report here an unusual case of maxillary sinus EP coexisting with oral squamous cell carcinoma (SCC) in a patient without any identified environmental risk or predisposing factors. The maxillary sinus mass proved to be radioresistant, with distant metastasis of EP in the tonsil and thoracic skin.
