Résumé :

Introduction: Head and neck cancer (HNC) is a significant global health issue, with Head and Neck Squamous Cell Carcinoma (HNSCC) ranking among the most prevalent cancers worldwide. In particular, India faces high incidence rates due to tobacco and areca nut usage. While HNSCC primarily affects the oral cavity carcinoma (OC), larynx, and oropharyngeal carcinoma (OPC) outcomes are linked to HPV status and T-, N-, and M-status. The necessity of elective neck dissection (END) for contralateral clinically node-negative (cN0) necks remains debated, with limited literature on its impact. Methodology

Résumé :

Bird necks display unparalleled levels of morphological diversity compared to other vertebrates, yet it is unclear what factors have structured this variation. Using three-dimensional geometric morphometrics and multivariate statistics, we show that the avian cervical column is a hierarchical morpho-functional appendage, with varying magnitudes of ecologically driven osteological variation at different scales of organization. Contrary to expectations given the widely varying ecological functions of necks in different species, we find that regional modularity of the avian neck is highly conserv

Despite a diversity of about 10 000 extant species, the sophisticated avian ‘body plan’ has not much changed once it was achieved around 160 Ma after the origin of powered flight. All birds are bipedal having wings, a rigid trunk, a short and ossified tail, a three-segmented leg and digitigrade feet. The avian neck, however, has always been regarded as a classic example of high variability ranging from short necks in songbirds to extremely long, serpentine necks in herons. Yet, the wide array of small to very large species makes it difficult to evaluate the actual neck length. Here, we investi

A retrospective review of 302 previously untreated patients with primary supraglottic carcinoma was undertaken to ascertain the efficacy of postoperative radiotherapy. The 302 patients underwent a total of 383 functional neck dissections and 45 classic radical neck dissections. Pathological examination revealed nodal involvement in 117 patients (39%). In the histologically N0 group, the incidence of contralateral neck recurrence when a unilateral neck dissection and postoperative radiotherapy were carried out was 8%, rising 21% when no postoperative radiation was given. There was no difference

Résumé :

In the article, from the total set of dimensions of the crankshaft forgings, geometric accuracy indicators reflecting their complex spatial warping - the diametrical dimensions of the root and connecting rod necks, angular deviations of the connecting rod necks, the curvature of the third root neck, transverse displacement along the die line - are highlighted. To estimate the value of spatial warping according to the selected accuracy indicators during the period of durability of the engravings of die inserts, a batch of crankshaft forgings was measured, followed by probabilistic and statistic

Aims In computer simulations, the shape of the range of motion (ROM) of a stem with a cylindrical neck design will be a perfect cone. However, many modern stems have rectangular/oval-shaped necks. We hypothesized that the rectangular/oval stem neck will affect the shape of the ROM and the prosthetic impingement. Methods Total hip arthroplasty (THA) motion while standing and sitting was simulated using a MATLAB model (one stem with a cylindrical neck and one stem with a rectangular neck). The primary predictor was the geometry of the neck (cylindrical vs rectangular) and the main outcome was th

Résumé :

The management of the NO neck in patients with head and neck cancer is controversial. Neck dissection provides important staging information that guides patient treatment. We examined the feasibility of using a dye technique for staging patients by sentinel lymph node biopsy (SLNBX). We studied seven patients with previously untreated early-stage squamous cell carcinoma of the oral cavity and NO necks. Each patient underwent SLNBX guided by an intraoperative injection of 1% isosulfan blue dye. An open biopsy of the sentinel node was followed by neck dissection. We identified the sentinel node

An increasingly significant area of research with several applications in numerous disciplines is that of multi-neck Helmholtz resonators. This research is set to explore the accuracy and applicability of the finite element method (FEM) for the calculation of the resonance frequency of multi-neck Helmholtz resonators. The FEM is employed for the estimation of the resonance frequency in various cases of multi-neck Helmholtz resonators: with cylindrical or spherical bodies, with unflanged or flanged necks of various dimensions and with various combinations of the above.

Résumé :

Lymph node metastasis stands out as the most influential prognostic factor in head and neck squamous cell cancer. Although radical neck dissection was the initial method, over time, more selective neck dissection techniques which preserves more functions, have been introduced. The introduction of surgical endoscopy and robotic systems make selective neck dissection more feasible with hidden scar. This paper describes the details of the preparations and surgical procedures for endoscopic selective neck dissection (levels I, II, and III) through a retroauricular approach.

Abstract This contribution is part of a project concerning the creation of an artificial dataset comprising 3D head scans of craniosynostosis patients for a deep-learning-based classification. To conform to real data, both head and neck are required in the 3D scans. However, during patient recording, the neck is often covered by medical staff. Simply pasting an arbitrary neck leaves large gaps in the 3D mesh. We therefore use a publicly available statistical shape model (SSM) for neck reconstruction. However, most SSMs of the head are constructed using healthy subjects, so the full head recons

<strong>Background: </strong>In high-risk areas like India, head and neck cancers are a huge global health burden. Squamous cell carcinomas can develop in a variety of head and neck regions as a result of prolonged exposure to risk factors like alcohol, tobacco, and viral infections. Unique demographic and healthcare issues in India make it more difficult to manage this malignancy, including delayed diagnoses, poor access to care in rural areas, and side effects from treatment such shoulder weakness.

Because of an estimated 20–30% prevalence of occult lymph node (LN) metastases in patients with head and neck squamous cell carcinoma (HNSCC), neck dissection is often proposed, despite its potential morbidity. In this systematic review and meta-analysis, the diagnostic performance of FDG PET-CT in detecting occult LN metastases was evaluated in patients with clinically negative necks (cN0) and in whom histopathology of a neck dissection specimen served as gold standard. Overall, 16 studies out of 2062 screened on PubMed and EMBASE fulfilled the inclusion criteria (n = 1148 patients). Seven of

Various cytochemical tests on the wheat stem rust fungus were used to determine differences in components of the walls of the haustorium mother cell at the host cell penetration site and the haustorial neck and body and to describe some of the chemical properties of the extrahaustorial matrix. There were two transition zones with respect to wall composition. The first was at the host cell penetration site; chitin, present in haustorium mother cell walls, was not detected in haustorial neck walls. The second transition zone was at the neck ring; compared with walls of the proximal neck region,

<strong>Background:</strong> Paediatric neck masses are a common disease entity in Otorhinolaryngology ranging from benign to malignant conditions. Most neck masses in pediatric patients are either inflammatory lesions or benign tumors but a considerable portion of pediatric neck mass constitutes malignant tumors also. To avoid fatal complications, paediatric neck masses need early diagnosis and prompt management. Paediatric neck mass can be divided into inflammatory, developmental (congenital), and tumorous lesions (either benign or malignant). <strong>Materials and Method:</strong>
