Sentinel Lymph Node Biopsy in Early Stages of Oral Squamous Cell Carcinoma Using the Receptor-Targeted Radiotracer Tc-Tilmanocept.

Neck management in patients with early-stage, clinically node-negative oral squamous cell carcinoma (OSCC) remains a matter of discussion. Sentinel lymph node biopsy (SLNB) represents a treatment alternative to avoid elective neck dissection (END) in this cohort and different protocols and tracers exist. Here we present the clinical outcome of SLNB using Tc-tilmanocept in a two-day protocol in patients suffering from early-stage OSCC.

Imaging foreign bodies in head and neck trauma: a pictorial review.

Open injuries bear the risk of foreign body contamination. Commonly encountered materials include gravel debris, glass fragments, wooden splinters or metal particles. While foreign body incorporation is obvious in some injury patterns, other injuries may not display hints of being contaminated with foreign body materials.

Incidence and survival of HNSCC patients living with HIV compared with HIV-negative HNSCC patients.

Purpose: The aim was to analyze the incidence and survival of patients living with HIV (PLWH) with head and neck squamous cell carcinoma (HNSCC) and to compare with a control group of HIV-negative HNSCC patients.

Methods: Clinicopathological data and predictors for overall survival (OS) and disease-free survival (DFS) were investigated (2009-2019).

Results: 50 of 5151 HNSCC patients (0.

Detectability of foreign body materials using X-ray, computed tomography and magnetic resonance imaging: A phantom study.

Purpose: To evaluate the effectiveness of plain radiography (X-ray. XR), computed tomography (CT) and magnetic resonance imaging (MR) in visualising commonly seen foreign bodies. A special focus was put on objects relevant to head and neck surgery.

Submillisievert chest CT in patients with COVID-19 - experiences of a German Level-I center.

Purpose: Computed tomography (CT) is used for initial diagnosis and therapy monitoring of patients with coronavirus disease 2019 (COVID-19). As patients of all ages are affected, radiation dose is a concern. While follow-up CT examinations lead to high cumulative radiation doses, the ALARA principle states that the applied dose should be as low as possible while maintaining adequate image quality.

Presentation of cervical metastases and pathological mandibular fracture due to pulmonal adenocarcinoma: A case report.

Introduction: Oral metastatic tumors due to malignancies at distant locations are very rare. There are only few cases in the literature reporting about mandible/cervical metastases. Sometimes the oral finding is the manifestation of the disease.

Advantages of a T1-Weighted Gradient-Recalled Echo (GRE) Sequence With a Radial 3D Sampling Approach Versus 2D Turbo Spin-Echo and Cartesian 3D GRE Sequences in Head and Neck MRI.

The purpose of this study is to compare the image quality, including artifacts, of a T1-weighted gradient-recalled echo (GRE) MRI sequence with a radial sampling approach to that of both 2D turbo spin-echo (TSE) and cartesian 3D GRE MRI sequences performed in the head and neck region. The retrospective study included 26 datasets of patients who underwent MRI examination for inflammatory or neoplastic diseases of the head and neck region performed using a 1.5-T system.

Primary oral manifestation of Langerhans cell histiocytosis refractory to conventional therapy but susceptible to BRAF-specific treatment: a case report and review of the literature.

Langerhans cell histiocytosis (LCH) is a diagnostic and therapeutic challenge. We report on a rare case of its primary oral manifestation that was treated successfully with the BRAF-specific agent, vemurafenib, after insufficient standard LCH treatment. This case underlines the importance of proper diagnosis and the evaluation of targeted therapy as a valuable tool in LCH treatment.

[Frequency and management of complex facial fractures-an oral and maxillofacial surgical assessment].

Introduction: The treatment of facial fractures is an integral part of the oral and maxillofacial surgical treatment spectrum. In the case of complex fractures that involve multiple levels of the facial skeleton associated with severe concomitant injuries, an individual and interdisciplinary treatment approach is needed, which requires the infrastructure of a national trauma center.

Objective: The aim of this study was to analyze the incidence and management of patients with complex facial fractures and considering the concomitant injury pattern.

Sublingual cysts of different entities in an infant - A case report and literature review.

Background: Congenital cysts and fistulas of the neck are common in children, often located in the head and neck area. Belonging to the group of tumor-like conditions, dermoid and epidermoid cysts are dysontogenetic lesions with seldom multiple co-occurrences in infants.

Case Report: We report on a nine-month-old female with a persisting congenital fistula of the tongue.

Penetrating Foreign Bodies in Head and Neck Trauma: A Surgical Challenge.

Penetrating foreign bodies of different origins in the head and neck are rare and potentially dangerous injuries, which might pose problems for their detection, primary care, and final treatment. Depending on the severity of the underlying trauma, some injuries present a higher risk for the presence of foreign bodies. Minor wounds, including common lacerations, are likely to be contaminated with loose gravel debris or dental fragments, and need to be distinguished from severe wounds caused by impalement, shootings, stabbings, and explosions.

Enhanced radiographic visualization of resorbable foils for orbital floor reconstruction: A proof of principle.

Purpose: Despite the advantages and broad applications of alloplastic resorbable implants, postoperative radiological control is challenging due to its radiolucency. The aim of the present study was to evaluate the radiographic visibility of newly developed materials for orbital floor reconstruction.

Materials And Methods: The radiographic visibility of four different material combinations consisting of poly-(L-lactic acid)/poly-glycolic acid (PLLA/PGA) or poly(D,L-lactic acid) (PDLLA) enriched with magnesium (Mg), hydroxyapatite (HA) or β-tricalcium phosphate (β-TCP) with various layers of thicknesses (0.

A novel classification scheme for advanced laryngeal cancer midline involvement: implications for the contralateral neck.

Purpose: There are insufficient data concerning risk factors for contralateral regional metastases in laryngeal cancer. The aim of this study was to investigate the frequency and risk factors for contralateral lymph node metastases and their dependence on midline involvement of the primary tumor in patients with advanced laryngeal squamous cell carcinoma.

Methods: 58 consecutive patients (8 females, 50 males; mean age 64.

Computed tomography-based virtual fracture reduction techniques in bimandibular fractures.

Purpose: Computer-assisted preoperative planning (CAPP) usually relies on computed tomography (CT) or cone beam CT (CBCT) and has already become an established technique in craniomaxillofacial surgery. The purpose of this study was to implement CT-based virtual fracture reduction as a key planning feature in patients with bimandibular fractures.

Material And Methods: Nine routine preoperative CT scans of patients with bilateral mandibular fractures were acquired and post-processed using a mean model of the mandible and Amira software extended by custom-made scripting and programming modules.

Patient and treatment-related risk factors for osteoradionecrosis of the jaw in patients with head and neck cancer.

Objective: The purpose of this study was to evaluate risk factors for and the incidence of osteoradionecrosis (ORN) of the jaw in patients with head and neck cancer.

Study Design: This study was a retrospective analysis of the risk for ORN and outcome for 149 of 540 patients with head and neck cancer of the oral cavity (65%), oropharynx (26%), or other head and neck sites (9%) treated with radiotherapy between 2004 and 2009. ORN was graded according to Late Effects of Normal Tissues/Somatic Objective Management Analytic Scale (LENT/SOMA) criteria.
