Full textThis thesis analyses the rise of the caesarean section in italy, from the 1750s to the 1850s, with reference to other european regions, especially france. The caesarean operation provides an historical viewpoint for understanding fundamental changes in birth-giving practices at a time when ethical, deontological and scientific values were being transformed. Given the operation's high mortality rate, it implied a deliberate decision to save the baby's life before that of the mother. The thesis explores these transitions, adducing reasons for such changes in the medical, religious, and political worlds of the time which led to the emergence of a neuw image of the baby and the powerful demands for its materialand spiritual survival. The chapters of the thesis are divided according to the areas considered : religious aspects (ch. 2) ; the political and institutional world (ch. 3) ; the scientific field (ch. 4) ; the social world (ch. 5) ; and the collective imagery and representation (ch. 6)

Full textThe ethical questions about the face transplant seem unavoidable. What risks can be tolerated, not irresponsibly, but in conscience, in the interest of the patient ? To what extent the ethical issues have been addressed by surgical teams prior to the completion of transplants ? Can ethics justify this intervention? A study of the scientific literature and general press of every team having performed the face transplant was conducted to determine the ethical issues raised by this transplantation. They affect both the donor and his family and the recipient. From these items, a questionnaire survey was conducted with the same surgical team to assess the management of these ethical issues. To open the debate, involving the community for educational and trace the way of the new acceptances, 1000 French surgeons were also interviewed by a questionnaire. The results were used to explore the issue of consent of the donor's family, the place of family in respect of memory and the will of the deceased. Explorer also respect the body, medical confidentiality, respect for donor anonymity, the role of media in the first major surgery, and finally the concept of consent of a vulnerable patient and that of the risk / benefit ratio for treatment whose benefits are still uncertain. As part of the face such questions are essential human dimension ... To testify early work focused on the symbolism of the face, disfigurement, historical, legal, institutional, and religious challenges

Full textAnatomy (section 42-01 of the National University Council) is both the oldest scientific and medical discipline (from whom “nothing is yet to expect” according to some of our collegues), and an up-to-date science directely connected to the clinical pratice. The nerves of the deep regions of the head illustrate this theme very well. In the field of oral and maxillofacial surgery, of electrophysiological exploration of the sensitory branches of the mandibular nerve (for example in the follow-up of lingual nerve injury during wisdom teeth extraction, the first cause of juridic litigation in France for oral surgeons and dentists), or in medical imaging, an accurate knowledge of these structures is mandatory for the developments of our clinical practices. Some anatomical and anatomo-clinical studies have been designed in this field, demonstrating the actuality and vitality of our discipline

Full textIntroduction: Ethics in oral-maxillofacial surgery (OMS) remain understudied. The purposes of this dissertation were (1) to identify the ethical problems of human subject protection (HSP) and conflicts of interest (CoI) in OMS researches, (2) to propose the guidelines as to maintain scientific integrity and ethical standards in this surgical speciality, and (3) to analyse clinical data concerning jaw lesions to discuss the ethical considerations on clinical decision-making. Methods: This cumulative thesis consisted of 2 parts: research ethics and clinical ethics. Part 1: research ethics, included 1 narrative review, 4 retrospective and 2 cross-sectional studies on: (1) research misconduct, (2) HSP and CoI in OMS journals, (3) HSP and CoI in researches on 2 OMS innovations (piezoelectric surgery; endoscope-assisted submandibular sialadenectomy), (4) publication bias in the OMS literature, (5) ethical issues in the guideline to authors of OMS journals, and (6) a questionnaire survey enrolling 326 maxillofacial surgeons worldwide. Part 2: clinical ethics, comprised 1 systematic review and 3 retrospective studies on: (1) osteoradionecrosis, (2) odontogenic keratocysts, (3) ameloblastoma, and (4) complications of fibular free flaps. Descriptive and univariate statistics were computed when appropriate, and a P-value of < 0. 05 was considered statistically significant. Results: HSP and disclosure of CoI in OMS researches are still lacking. The possible reasons are (1) the OMS journals themselves (lack of ethical issues in the instructions to authors and/or failure of editors and/or reviewers to be strict with their own regulations/policies and international ethical standards) and/or (2) the OMS authors (lack of ethical education, inadequate research experience, bias from career self-interest or financial gains, ignorance about research ethics, or a combination of these). Clinical data on jaw lesions and their management can be incorporated into the ethical approach to clinical decisionmaking. However, the studies on this matter usually contain inadequate internal validity. Conclusions: The results of these studies suggest that HSP and disclosure of CoI receive little attention from the OMS speciality. It is, therefore, high time to have appropriate oversight of ethical breaches and implement the measures as a standard in peer-review publishing. An author/investigator has to adhere strictly to the research ethics standards. Adequate research training for oral-maxillofacial surgeons would help reduce both intentional and unintentional scientific malpractice. Ethics and clinical decisionmaking require further investigations
Hintergrund: Ethische Aspekte in der Mund-Kiefer-Gesichtschirurgie (MKG-Chirurgie) wurden bislang kaum beleuchtet. Anliegen der Dissertation war [1] die Identifikation von Problemen beim Schutz des Menschen und Interessenkonflikte der MKG-chirurgischen Forschung, [2] die Formulierung von Leitlinien zur Sicherstellung der wissenschaftlichen Integrität und der ethischen Standards in dieser chirurgischen Disziplin, und [3] die Analyse klinischer Daten zu Erkrankungen des Kiefers zur Erörterung ethischer Erwägungen auf die klinische Entscheidungsfindung. Methode: Diese kumulative Dissertation gliedert sich in 2 Hauptteile: [1] Ethikforschung und [2] Klinische Ethik. Der Teil 1: Ethikforschung, beinhaltet 1 traditionellen Übersichtsartikel, 4 retrospektive Studien und 2 Querschnittstudien zu [1] Fehlleistungen in der Forschung (wissenschaftliches Fehlverhalten), [2] Schutz des menschlichen Individuums in der MKG-chirurgischen Literatur, [3] Schutz des menschlichen Individuums bei zwei neuartigen MKG-chirurgischer Verfahren (piezoelektrische Chirurgie; endoskopisch gestützte Exstirpation der Glandula submandibularis), [4] Ergebnisverzerrung (Publikationsbias) in der MKG-chirurgischen Literatur, [5] Ethik-Aspekte in den Richtlinien für Autoren von MKG-chirurgischen Zeitschriften und [6] eine auf Fragebögen basierende Querschnittstudie, welche ein Kollektiv von 326 MKG-Chirurgen weltweit erfasst. Der zweite Teil: Klinische Ethik, enthält 1 systematischen Übersichtsartikel und 3 retrospektive Studien zu den Themen [1] Osteoradionekrose, [2] odontogenen Keratozyste, [3] Ameloblastom und [4] Komplikationen des freien Fibulatransfers. Deskriptive und univariate statistische Daten wurden, sofern möglich, berechnet; für das Signifikanzniveau konnte ein p-Wert von < 0,05 festgelegt werden. Ergebnis: Innerhalb der MKG-chirurgischen Forschung gibt es noch immer Defizite hinsichtlich des Schutzes des menschlichen Individuums und der Offenlegung von Interessenkonflikten. Mögliche Ursachen hierfür reichen von [1] redaktionellen Problemen bei den MKG-chirurgischen Zeitschriften (fehlende Ethik-Standards in den Instruktionen für Autoren, Unschärfen seitens der Herausgeber bzw. Gutachter bezüglich der strikten Umsetzung von journaleigenen oder globalen Regeln) bis hin zu [2] autorenbezogenen Problemen (Wissenslücken, Verwerfungen durch Karrieredenken, finanzielle Interessen); auch Kombinationen multipler Gründe sind denkbar. In die klinische Daten über kieferchirurgische Erkrankungen und deren Management sollten ethische Ansätze bei der therapeutischen Entscheidungsfindung einfließen. Bisherigen Studien zu diesem Thema fehlt es in der Regel an interner Validität. Schlussfolgerung: Die Ergebnisse der Untersuchung sprechen dafür, dass dem Schutz des menschlichen Individuums und der Offenlegung von Interessenkonflikten innerhalb der MKG-chirurgischen Forschung bisher zu wenig Aufmerksamkeit geschenkt wird. Es ist somit höchste Zeit, geeignete Überwachungsverfahren zum Schutz vor ethischen Rechtsverletzungen zu etablieren und diese Maßnahmen als Standard in den Begutachtungsprozess für internationale Publikationen (‚peer-review publishing‘) einzuführen. Jeder Autor bzw. Forscher sollte sich strikt an ethische Standards halten. Geeignete diesbezügliche Fortbildungen für MKG-Chirurgen könnten bewusste und unbewusste wissenschaftliche Fehltritte vermeiden helfen. Die klinische Entscheidungsfindung unter ethischen Aspekten bedarf in Zukunft weiterer Untersuchungen

Full text« Broken Faces » embody the horror of war, and the violence that we try to keep from seeing and seek to forget. In 1921, three horribly disfigured soldiers founded an association to corne to the aid of fellow comrades. They chose to give them back a social existence, something to work with, a careful look. More than one hundred years later, their story is still current for the new generations injured in combat. How does one survive when one's body has lost its protective envelope, when it unveils the shapelessness of flesh, a face that is indistinguishable from an animes? How does one get back one's individuality when the only visible part of the body, inaccessible even to oneself, becomes something monstrous? The evidence presented by « Broken Faces » forces one to question the theory that comprises the basic principe of identity in human beings, and to rethink the paradigm of otherness. This entails first of all comprehending the effects of the injuries on the physical reality, listening to the history of the person on the « otherness way ». This narcissistic reconstruction requires a long period of work in front of the mirror, under the eyes of others, and by coming to terms with the limitations of plastic surgery, but also require the surgeon to question the ethical boundaries of his practice. « Broken Faces » we met have tried to forge new ties with their peers, to pass on their experience. Entering in an « ethnic group » with common features has value of « symbolic transplant », recognition, and gives the broken face the face again

Full textObjectives :Orthognathic surgery induces a change in the morphology of the face. The functional and aesthetic effects are well known, but the psychological effects are more difficult to explore. This research proposes to investigate 1) the impact of orthognathic surgery on several psychological and social variables and 2) the impact of personality traits of dissatisfied patients on postoperative dissatisfaction. Method : this longitudinal research includes 288 patients undergoing orthognathic surgery. A self-administrated questionnaire was distributed one month before orthognathic surgery (T1), three to six months after (T2) and one year after (T3). Five studies were conducted. Three of them assess the impact of orthognathic surgery on mentalhealth (GHQ-28), self-esteem (SEI), body image (MBSRQ and SATAQ), quality of life (WHOQOL-BREF) and personality (BFI). The fourth focuses on the validation of tools for evaluating postoperative satisfaction. The fifth describes the characteristics of dissastisfied patients and attempts to identify predictors of dissatisfaction. Results : Study 1. There is an improvement of severe depression at T2 but there is no improvement of mental health and self-esteem at T3. Body image is improved but appearence orientation does not change and overweight preoccupations significantly increase; Study 2. Quality of life is partially improved (social relationships and physical health) but it remains lower than the general population's. Study 3. Extraversion, agreableness and neuroticism are modified at T2 and close to their original state at T3. The surgery improves openness but not consciousness. Study 4. Five scales have been validated to explore postoperative satisfaction : 1) scale of postoperative satisfaction, scales of 2) familial and social support, 3) improvements seen in my life, 4) satisfaction with the information and 5) quality of relationship with the surgeon

Full textIn our routine practice of orthognathic surgery, we face the limitations of conventional planning and simulation tools, and the lack of convenient intraoperative assistance. If computer science has provided satisfactory solutions for planning, yet simulation and navigation appear improvable. The aim of our research was to provide novel tools to improve these issues. Therefore, we first developed a semi-automated segmentation pipeline allowing accurate and timeefficient patient-specific 3D modeling. We then conceived 1mm-accurate facial soft tissue simulation software based on a mechanical massspring model. Finally, we developed a real-time navigation system based on minimally-invasive electromagnetic tracking, featuring a novel user-friendly interface. Evaluation showed that our software reduced time and accuracy discrepancy between operators. Along with educational purposes, such a system benefited especially trainees. Surgeons emphasized system relevance in the treatment of both, complex and common deformities. Such developments establish a software suite that could provide significant improvement for patient optimal care

Full textChildren with intellectual disabilities experience major inequality in the field of oral health. Opposition behaviors are very common. The care is then carried out sometimes in difficult conditions. This work examines the ethical issues faced by the dentist in the refusal of care in children intellectual disabilities. The objectives are: (1) to expose elements of contextualisation (2) to identify the practices of dental care in a national and international contexte and to initiate the philosophical reflection (3) to focus on the opinions and perceptions of practitioners to explain these practices and to identify areas of ethical tension (4) to propose a synthesis and a discussion. Our research is based on two studies, each of which is directed at dentists who are specialists in special care dentistry in children. A deductive approach was conducted to study practitioner profiles according to their practices and the opinions they have of these practices (online quantitative survey) and analyzed by MFA (Multiple Factor Analysis). An inductive approach based on focus groups was conducted to study the perception and opinion of practitioners. The thematic content analysis made it possible to understand the motivations and difficulties encountered. The results showed that most dentists are part of a teleological approach when they have to choose between respect for autonomy and beneficence. Nevertheless, if these constrained decisions are impregnated with a deontological scruple, this guarantees their ethical character. It would be necessary to develop education and the ethics of the discussion to reconcile the dual technical and emotional requirements of care
Dagnes, Nicole. "3D human face analysis for recognition applications and motion capture." Thesis, Compiègne, 2020. http://www.theses.fr/2020COMP2542.
Full textThis thesis is intended as a geometrical study of the three-dimensional facial surface, whose aim is to provide an application framework of entities coming from Differential Geometry context to use as facial descriptors in face analysis applications, like FR and FER fields. Indeed, although every visage is unique, all faces are similar and their morphological features are the same for all mankind. Hence, it is primary for face analysis to extract suitable features. All the facial features, proposed in this study, are based only on the geometrical properties of the facial surface. Then, these geometrical descriptors and the related entities proposed have been applied in the description of facial surface in pattern recognition contexts. Indeed, the final goal of this research is to prove that Differential Geometry is a comprehensive tool oriented to face analysis and geometrical features are suitable to describe and compare faces and, generally, to extract relevant information for human face analysis in different practical application fields. Finally, since in the last decades face analysis has gained great attention also for clinical application, this work focuses on musculoskeletal disorders analysis by proposing an objective quantification of facial movements for helping maxillofacial surgery and facial motion rehabilitation. At this time, different methods are employed for evaluating facial muscles function. This research work investigates the 3D motion capture system, adopting the Technology, Sport and Health platform, located in the Innovation Centre of the University of Technology of Compiègne, in the Biomechanics and Bioengineering Laboratory (BMBI)

Full textHuman face plays an important role interpersonal communication. Facial dysfunction or disfigurement due to trauma or pathologies may impede normal social activities. Surgical treatment is often necessary. Nowadays, treatment outcome and rehabilitation condition are estimated only by qualitative methods, such as visual observation and palpation. In expectation of providing quantitative criteria, this thesis proposes to model facial mimics using FEM (Finite Element Method) on the basis of MRI (Magnetic Resonance Imaging) data. A subject-specific face model was reconstructed based on segmentation of MRI data; it contains bony parts, mimic muscles (e.g. zygomaticus major muscle), subcutaneous soft tissues and skin. Identification of biological soft tissues was conducted through bi-axial tension tests and numerical modeling. Then the geometric model was meshed to conduct FE calculations simulating three facial mimic movements (smile, pronunciation of sound “Pou” and “O”). Muscle was modeled as quasi-incompressible, transversely-isotropic, hyperelastic material, with activation ability. Relevant information (e.g. contraction amplitude of muscle) used in simulation was extracted from measurement of MRI data. It is to be noted that the same experimental MRI data as used in modeling was taken as validation reference for simulation results. This study can be applied clinically in evaluation of facial treatment andpostoperative recovery

Full textAn hybrid bone substitute, based on a specific biomaterial (scaffold) and living cells, was studied, developed with a tissue engineered method and characterized. It should meet the expectations of the maxillofacial surgery : a standard process which could fit with the complex geometries of each patient’s bone mass loss, a flexible shape with an easy handling, a prevascularization and a sufficient mechanical cohesion. A sheet-like shape was thus designed and developed in a specific flat cell culture chamber, with a monolayer of calcium phosphate granules as a scaffold. After both biological and mechanical full characterizations with a cell line, the process was adapted to a coculture of human primary cells (stem and endothelial cells). Relevant differentiation and prevascularization were highlighted but the mechanical cohesion could be noticed as too low to ensure an easy handling during the surgery. The last part of this thesis project was thus the set-up of a device for electrospun polymer fibers in order to use them as a new scaffold. The production of these materials was efficiently performed for several polymers. The differentiation potential for bone and tendon lineages was studied and compared to other scaffolds from national and international collaborations. The application of mechanical solicitations to the substitutes during cellculture was also studied

Full textRobot assisted surgery is slowly invading our world, taking side with regards to medical ethics. In a not too far future, one might watch this type of surgery operated between surgeons and patients thousands of miles apart. Can we then accept the image reflected on the screen as a valid substitute to the hand and eyes of the technician? Are we then accepting the surgeon as a technician whose tools would be limited to sticks and a screen? In fact, recent evolution in the field of medical ethics show that patients expect much more than the mere physical repair and consider that human direct contact with the surgeon is essential. This attitude appears as an invitation to avoid placing excessive emphasis on the technical aspect of surgery to the detriment of clinical aspect and human relationship
