Methods We focused on exploring the dynamics of the oropharyngeal pavilion in voice professionals using Cone-Beam Computed Tomogra-phy (CBCT).

Morphological Evidence for a Unique Neuromuscular Functional Unit of the Human Vocalis Muscle.

Human vocalization is a complex process that is still only partially understood. Previous studies have suggested the possibility of a localized neuromuscular network of the larynx. Here we investigate this structure in human dissection specimens using multiple immunofluorescence and transmission electron microscopy (TEM).

Vascular Perspectives of the Midfacial Superficial Musculoaponeurotic System.

: Presently, data on the vascularization of the superficial musculoaponeurotic system of the face (SMAS) are lacking. Thus, the present study aimed to provide new conclusive data about the topography, density, and relationship of the SMAS blood vessels with other components, namely, the fibrous connective tissue and muscles. : The study included a control lot of 42 cases from the archive of the radiology department.

Coactivation of the Laryngeal Muscles in Pigs Without External Neural Control Indicates Existence of an Intrinsic Neuronal Network.

Electrophysiological studies of the larynx expose the mechanisms by which voice production is controlled. Previous studies have revealed certain phenomena during laryngeal oscillations that suggest a complex control mechanism. Starting from the principle of agonist-antagonist muscular pairing, the aim of this study was to gain a deeper insight into the function of the cricothyroid (CT) and thyroarytenoid (TA) muscles, both central to voice production.

Advances in Molecular Research on Hip Joint Impingement-A Vascular Perspective.

With the rise in longevity within the population, medicine continues to encounter fresh hurdles necessitating prompt actions, among which are those associated with hip joint aging. Age-related arthropathies encompass damage to bones' articulating extremities and their supporting structures, such as articular cartilage, and alterations in the quantity and quality of synovial fluid. This study aims to summarize the biomolecular methods of hip joint evaluation focused on its vascularization, using data correlated with biomolecular research on other joints and tissues, in order to reach an objective opinion of the study prospects in this field.

Aging of Superficial Musculoaponeurotic System of the Face-Novel Biomarkers and Micro-CT Relevance of Facial Anti-Gravity Support.

The soft superficial tissues of the face are against gravity through an intricate network of ligaments and ligamentous attachments. The aim of this investigation is to delineate the relationship between the muscular, fibrous, and vascular components of the superficial musculoaponeurotic system of the face (SMAS) at the level of its periosteal fixation areas from advanced radiological and novel biomarkers' perspectives. These areas represent key points underlying skin aging and the longevity of restorative surgery results.

Muscular and neuronal control of voice production - forgotten findings, current concepts, and new developments.

Voice production has been an area of interest in science since ancient times, and although advancing research has improved our understanding of the anatomy and function of the larynx, there is still little general consensus on these two topics. This review aims to outline the main developments in this field and highlight the areas where further research is needed. The most important hypotheses are presented and discussed highlighting the four main lines of research in the anatomy of the human larynx and their most important findings: (1) the arrangement of the muscle fibers of the thyroarytenoid muscle is not parallel to the vocal folds in the internal part (vocalis muscle), leading to altered properties during contraction; (2) the histological structure of the human vocal cords differs from other striated muscles; (3) there is a specialized type of heavy myosin chains in the larynx; and (4) the neuromuscular system of the larynx has specific structures that form the basis of an intrinsic laryngeal nervous system.

Personalized Research on the Aging Face-A Narrative History.

Throughout history, people have struggled to find out the secret of youth. The aim of the manuscript is to review the main achievements regarding the exploration of the aging face phenomenon.

Thymus Surgery Prospectives and Perspectives in Myasthenia Gravis.

The thymus is a lymphoid organ involved in the differentiation of T cells, and has a central role in the physiopathogenesis of Myasthenia Gravis (MG). This connection is proved by a series of changes in the level of neuromuscular junctions, which leads to a decrease in the amplitude of the action potential in the post-synaptic membrane. Because of this, the presence of anti-cholinergic receptor antibodies (AChR), characteristic of MG, is found, which causes the progressive regression of the effect of acetylcholine at the level of neuromuscular junctions, with the appearance of muscle weakness.

Morphofunctional and histological patterns of blood vessels in the superficial cervicofacial musculoaponeurotic system in midlateral face regions.

Objective: The superficial cervicofacial musculoaponeurotic system (SMAS) is a complex network formed by mimic muscles and conjunctive tissue of the superficial fascia of the face.This study aimed to introduce new anatomofunctional data on the importance of the trans-SMAS distribution pattern of the skin microperfusion of the face and to underline the role of SMAS in maintaining the homeostasis of the vascular network that crosses it. Considering the fibrous and muscular matrix of the SMAS, using COLIII and MyoH2 antibodies, together with endothelial immunohistochemistry(IHC)intercellular adhesion molecule 2 marker, we determined the correlation of these structures and their interaction.

Clinical and morphofunctional identity of the nasal SMAS.

The fascial system of the face (superficial musculo-aponeurotic system, SMAS) in the nasal part is a sustained layer that connects the nearby regions. In this paper, we aimed to emphasize the presence of SMAS in different areas of the nasal region: ala nasi, nasolabial fold, nasal dorsum and radix. We performed three studies (anatomical, histological, and radiological) to demonstrate the existence of nasal SMAS.

Omphalocele and Cardiac Abnormalities-The Importance of the Association.

Omphalocele is the most common ventral abdominal wall defect. Omphalocele is associated with other significant anomalies in up to 80% of cases, among which the cardiac ones are the most frequent. The aim of our paper is to highlight, through a review of the literature, the importance and frequency of association between the two malformations and what impact this association has on the management and evolution of patients with these pathologies.

H-FABP Levels and Psycho-Emotional Improvement of CABG Patients during Cardiac Rehabilitation.

(1) Background: The heart-type fatty acid-binding protein (H-FABP) is a specific myocardial biomarker and high levels indicate ischemia regardless of patient-reported symptoms. Concurrently, major adverse cardiovascular events and surgery such as coronary artery by-pass grafting (CABG) cause substantial psycho-emotional distress e.g.

Morpho-functional and radiological approach of poststroke seizures.

Epilepsy is characterized by recurrent seizures that cannot be associated with other specific causes. The presence of a single convulsive or tonic seizure after a stroke does not necessarily mean that a person develops a form of epilepsy unless the convulsions become chronic and recurrent poststroke epilepsy. The purpose of our study is to highlight the existence of a connection between the type and the topography of a vascular stroke on the one hand, and on the other hand, the type of seizures that have occurred and how long they have occurred after the stroke.

Hidden Anatomy of Opera Singers.

Anatomical considerations on the masseteric fascia and superficial muscular aponeurotic system.

The masseteric region is considered by the most researchers as a subdivision of the parotideomasseteric region. Because of its surgical significance, we emphasize it has distinctive morphofunctional features. The aim of this manuscript is to highlight particular characteristics of the masseteric region and practical applications of this concept.

Morphofunctional evaluation of buccopharyngeal space using three-dimensional cone-beam computed tomography (3D-CBCT).

The present study aims to identify the anatomical functional changes of the buccopharyngeal space in case of singers with canto voice. The interest in this field is particularly important in view of the relation between the artistic performance level, phoniatry and functional anatomy, as the voice formation mechanism is not completely known yet. We conducted a morphometric study on three soprano voices that differ in type and training level.

The existence of labial SMAS - Anatomical, imaging and histological study.

Cutaneous insertion of the facial mimic muscles concerns, at different levels, the superficial fascia of that region. A superficial musculoaponeurotic system is described at face level that facilitates skin insertion of the facial expression muscles through the superficial fascia that acquires particular functional aspects in each region of the face. The existence of a musculofascial system is seen controversial among anatomists, which is why the purpose of this study is to establish its existence at the oral region.

Morphological changes in support mechanism of superficial face layers in Moebius syndrome.

Moebius syndrome, also called congenital facial paralysis is a rare neurological disease, whose etiology is not fully elucidated. It affects especially facial and oculomotor cranial nerves and its clinical feature is peripheral facial paralysis. The objective of the study is to highlight the anatomical and functional changes in the Moebius syndrome and establish certain criteria that should be the basis for reparative surgery in this disease.

The morphometry of the laryngeal phonatory system - base of the anatomical study of the voice aptitudes.

Speaking is one of the characteristics of the human race and the main factor that has marked our progress over time. The singing voice is the crowning of the speech act and the main component of the lyrical manifestation of personality. Doctors in various fields, but especially anatomists have been concerned about discovering how the voice and the substrate of its variability are formed, but these aspects have not yet been fully deciphered.

The anatomical and functional characteristics of parotid fascia.

Parotid superficial and profound fascias are considered to originate from a bifurcation of the profound fascia. Its relations with the facial nerve, the continuity with platysma, temporal and zygomatic fascias suggest it is related to a superficial fascial complex rather with a profound one. The aim of this study is to add clues which sustain the theory of parotid fascia origin from superficial fascia of the face.

Morphological aspects of the rectal neovascularization in colorectal cancer - anatomical-surgical and imaging implications.

Colorectal neoplasia has an increasing incidence among the population, and this fact compels in achieving an early diagnosis and treatment protocols. The extramural vascular invasion (EMVI) score is a method used for staging cancer. It defines the presence of malignant cells in the blood vessels, outside its own vascular tunic.

Anatomical evidence regarding the existence of sustentaculum facies.

The face, seen as a unitary region is subject to the gravitational force. Since it is the main relational and socialization region of each individual, it presents unique ways of suspension. The elevation system of the face is complex, and it includes four different elements: the continuity with the epicranial fascia, the adhesion of superficial structures to the peri- and inter-orbital mimic muscles, ligaments adhesions and fixing ligaments of the superficial layers to the zygomatic process, and also to the facial fat pad.

Microanatomic aspects of arterial blood supply in rectal carcinomas--predictive models.

Rectum is divided into three distinctive regions (pelvic peritoneal, pelvic subperitoneal and perineal) regarding the regions where it is crossing through. Those three parts are individually not only due to their relation but due to their blood supply, also. The differences occur among them when one of them is involved into a neoplastic process.
