We have studied, in 37 adult patients, the anatomy of the sacral extradural (caudal) space using magnetic resonance imaging. The sacrococcygeal membrane (SCM) could not be detected in 10.8% of patients. The maximum depth of the caudal space adjacent to the SCM was beneath the upper third of the SCM in more than 90% of patients (mean depth 4.6 mm; range 1.0-8.0 mm). The shortest linear distance from the dura to the upper limit of the SCM varied considerably (60.5 mm; 34-80 mm) as did the volume of the caudal space excluding the foraminae and dural sac (14.4 cm3; 9.5-26.6 cm3). The dimensions of the caudal space and their variability have implications for clinical practice and a knowledge of these dimensions may increase both the reliability and safety of caudal techniques in adult patients.
Opinions are divided over the validity of total glossectomy without associated total laryngectomy for advanced carcinoma of the tongue. This retrospective study evaluates the oncologic and functional results obtained in 80 patients who underwent total glossectomy as a primary procedure or as salvage surgery. Satisfactory swallowing ability was obtained in 41 patients, and speech was understandable in 49 patients. The survival rate at 1 year was 65%, with early recurrence of the disease, which was especially frequent in patients with prior radiotherapy, being the major cause of death. The study confirms the poor prognosis of cases with mandibular involvement, and the fact that partial laryngectomy, when required, impairs functional results. In the light of the authors' experience, total glossectomy without total laryngectomy should only be undertaken in motivated and well-supported patients able to accomplish the difficult rehabilitation process.
Résumé -Les exostoses buccales sont des tumeurs osseuses bénignes des maxillaires qui se manifestent par des excroissances osseuses exophytiques. L'objectif de cette étude était d'effectuer une revue de la littérature sur ce sujet. Les données épidémiologiques, remontant pour certaines à plus d'un siècle, révèlent de grandes disparités selon les populations et les auteurs. La fréquence et la répartition des exostoses buccales diffèrent d'une population à l'autre. La susceptibilité génétique, les forces masticatoires et les parafonctions seraient des facteurs importants dans leur apparition et leur croissance. Leur exérèse permet, si nécessaire, de rétablir la fonction manducatrice.Abstract -Buccal exostoses: literature review. The buccal exostoses are benign bone tumors of the jaws. They are manifested by exophytic bony growths that develop on the maxillary bones. The aim of our study was to make a review of the literature on oral exostoses. Epidemiological studies, carried out for some for more than a century, reveals large differences between populations and the authors. The frequency and distribution of oral exostoses vary from one population to another. Genetic susceptibility, the masticatory and parafunctional forces are important factors in their appearance and growth. Their removal will restore the functions of manducation.Les exostoses buccales sont des excroissances osseuses exophytiques qui se développent à partir des maxillaires. On en distingue quatre types selon leur localisation : le torus palatin, les exostoses palatines, les torus mandibulaires et les exostoses vestibulaires (Fig. 1) [1, 2].Elles ne sont ni néoplasiques ni pathologiques et elles ont une croissance lente et progressive. Leur découverte se produit généralement au cours d'un examen clinique de routine, quelquefois fortuitement par le patient, lors d'une réhabilitation prothétique ou d'une gêne fonctionnelle [3][4][5]. L'objectif de cette étude est de réaliser une revue de la littérature sur les exostoses buccales.
Résumé -La tumeur fibreuse solitaire est une tumeur fibroblastique bénigne des tissus mous. Plusieurs localisations ont été décrites ; celles de la cavité buccale ont une prévalence de 3 %. L'étiologie est encore inconnue mais plusieurs auteurs ont retrouvé des antécédents de traumatismes. Dans cet article, on rapporte un cas de tumeur fibreuse solitaire évoluant dans la joue gauche, survenue chez une patiente âgée de 58 ans. L'exérèse de la tumeur sous anesthésie locale a permis l'examen anatomo-pathologique qui a diagnostiqué une tumeur fibreuse solitaire. Abstract -Solitary fibrous tumor of the cheek: a case report.Solitary fibrous tumor is a benign soft tissue tumor fibroblast. Several locations have been reported with oral rate those with a rate of 3% in the mouth. The etiology is still unknown, but the authors have described a history of trauma. We report in this paper a case of solitary fibrous tumor occurring in the left cheek, which occurred in an elderly patient of 58 years. The excision of the tumor under local anesthesia allowed the pathological examination, which diagnosed a solitary fibrous tumor.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
