Does Maxillomandibular Fixation Affect Respiratory Function? A Systematic Review.

ABSTRACT: This systematic review was carried out to determine if maxillomandibular fixation, used in the treatment of maxillary fractures, interferes with respiratory function, and appraised studies that evaluated pulmonary function using spirometry on patients with and without maxillomandibular fixation. Searches were conducted on the following databases: Medline/Pubmed, Embase, Cochrane, Web of Science, Scopus, and Scielo, in addition to a search of the grey literature and a manual search. Five studies were included in the qualitative analysis, but it was not possible to conduct a quantitative study due to the lack of data. Forced vital capacity, forced expiratory volume in the first second, the ratio of these values, and peak expiratory flow were the parameters studied. In all the studies included in this review, it was possible to observe the lowest respiratory parameter values during maxillomandibular fixation and, after removal, normal respiratory function was restored. Accordingly, it was possible to conclude that maxillo-mandibular fixation temporarily affects respiratory function, during use, but it is restored on removal, therefore, not precluding its use on healthy patients who have good nasal breathing prior to the procedure. However, in patients suffering from some form of respiratory limitation or pulmonary disease, and also mouth breathers, maxillomandibular fixation should not be used so as to avoid more severe respiratory complications, underlining the importance of preoperative pulmonary evaluation.

Ear pruritus: a new otologic finding related to temporomandibular disorder.

This prospective clinical study evaluated the correlation among temporomandibular disorder (TMD), otologic manifestations, and parafunctional habits in a sample of 100 patients with TMD. The subjects were evaluated by clinical examination, use of a simplified anamnestic questionnaire for TMD diagnosis, and the investigation of otologic manifestations and parafunctional habits of the stomatognathic system. The prevalence of TMD and correlations with otologic manifestations and parafunctional habits were calculated. Patients ranged in age from 13 to 70 years, and 79.0% of the patients were between the ages of 30 and 59 years. Women represented 88.0% of the sample. Otologic manifestations were found in 92.0% of patients with TMD. Sex showed a significant correlation with severity of TMD (P = 0.024). A significant correlation was observed between female patients and both otalgia (P = 0.036) and ear pruritus (P < 0.001). Otalgia showed a significant association with the symptoms of TMD (P = 0.003). Significant correlations between severe TMD and otalgia (P < 0.001), tinnitus (P = 0.010), ear pruritus (P < 0.001), and aural fullness (P = 0.014) were also observed. Ear pruritus, otalgia, and aural fullness are the most common otologic manifestations in patients with TMD, showing a significant correlation with the female sex, severity of TMD, and frequency of TMD symptoms.

The effect of biopolymer gel derived from sugarcane on healing of traumatic oral ulcers: an experimental study.

PURPOSE: The extracellular polysaccharide (EPS) is produced by the bacterium Zoogloea sp. and plays a positive role in tissue repair. The purpose of this study was to clinically and histologically compare the effects of EPS in the healing of traumatic oral ulcers in rats with the effects of triamcinolone. METHODS: Ulcers were induced in the oral mucous of 45 male Wistar rats, divided into three groups: control group, treated with triamcinolone, and treated with biopolymer gel. In the clinical evaluation, we considered the weight variation of the animals and the size of the lesion area, at baseline and on treatment days 1, 3 and 7. The histological parameters evaluated were the type and intensity of the inflammatory infiltration, the presence of necrosis and foreign body granuloma and the degree of re-epithelialization of the lesion. RESULTS: The reduction of the lesion area was greater in the animals treated with EPS, with no difference in the intensity of the inflammatory infiltration between the groups on days 3 and 7 of treatment. CONCLUSIONS: The results suggest that topical application of EPS in traumatic oral ulcers of rats promotes faster repair than triamcinolone ointment, without increasing the intensity of inflammatory infiltration under the lesion.

Orofacial clinical features in Arnold Chiari type I malformation: A case series.

BACKGROUND: Arnold Chiari malformation (ACM) is characterized by an anatomical defect at the base of the skull where the cerebellum and the spinal cord herniate through the foramen magnum into the cervical spinal canal. Among the subtypes of the condition, ACM type I (ACM-I) is particularly outstanding because of the severity of symptoms. This study aimed to analyze the orofacial clinical manifestations of patients with ACM-I, and discuss their demographic distribution and clinical features in light of the literature. MATERIAL AND METHODS: A case series with patients with ACM-I treated between 2012 and 2015 was described. The sample consisted of patients who were referred by the Department of Neurosurgery to the Oral and Maxillofacial Surgery Service of Hospital da Restauração in Brazil for the assessment of facial symptomatology. A questionnaire was applied to evaluate the presence of painful orofacial findings. Data are reported using descriptive statistical methods. RESULTS: Mean patient age was 39.3 years and the sample consisted mostly of male patients. A high prevalence of headache (50%) and pain in the neck (66.7%) and masticatory muscles (50%) was found. Only one patient reported difficulty in performing mandibular movements and two reported jaw clicking sounds. Mean mouth opening was 40.83 mm. CONCLUSIONS: ACM-I patients may exhibit orofacial symptoms which may mimic temporomandibular joint disorders. This study brings interesting information that could help clinicians and oral and maxillofacial surgeons to understand this uncommon condition and also help with the diagnosis of patients with similar physical characteristics by referring them to a neurosurgeon. Key words:Arnold-Chiari malformation, facial pain, diagnosis, orofacial.

The relationship between periodontite and diabetes mellitus type ii facing the new classification of periodontal diseases: literature review / A relação entre periodontite e diabetes mellitus tipo 2 frente a nova classificação das doenças periodontais: revisão de literatura

ABSTRACT Periodontal disease and type 2 diabetes mellitus are considered chronic diseases that at their core have a deep relationship with inflammation. It is assumed that there is a bidirectional relationship between periodontal disease and type 2 diabetes mellitus. It is estimated that approximately 10% of the world's population is affected by periodontal disease, in its most severe form, almost the same percentage estimated for people with diabetes, which is considered a 21st century emergency. The World Workshop for the Classification of Periodontal and Peri-implant Diseases and Conditions took place from September 9-11, 2017. The aim of this study is to analyze the results of this workshop with regard to the relationship between periodontal diseases/conditions and diabetes mellitus, in addition to conducting an integrative review on the topic. A literature review was conducted, using the Medline electronic databases via Pubmed, Scientific Electronic Library Online, Scientific and Technical Literature of Latin America and the Caribbean and Virtual Health Library. A new classification of periodontal disease included tools for individual assessment of the patient and recognizing risk factors that might negatively interfere in response to treatment. The occurrence of metabolic lack of control in periodontal patients with type 2 diabetes mellitus is now considered a factor of great importance for the assessment of individual susceptibility to the progression of periodontitis. Diabetes is believed to promote a hyper inflammatory response to bacterial challenge by modifying the tissue response of periodontal tissues.

RESUMO A doença periodontal e o diabetes mellitus tipo 2 são consideradas doenças crônicas que tem em seu cerne um profundo relacionamento com mecanismos inflamatórios, pressupõe-se que haja uma relação bidirecional entre doença periodontal e diabetes mellitus tipo 2. Estima-se que aproximadamente 10% da população do mundo seja afetada pela doença periodontal, na sua forma mais severa, quase o mesmo percentual estimado para portadores de diabetes, que é considerada uma emergência do século XXI. Entre 9 e 11 de setembro de 2017, ocorreu o World Workshop para a Classificação das Doenças e Condições Periodontais e Peri-implantares. O objetivo deste estudo é analisar o que está colocado por esta classificação sobre a relação entre doenças/condições periodontais e diabetes mellitus, além de fazer uma revisão integrativa a respeito do tema. Foi realizada uma revisão de literatura, a partir das bases de dados eletrônicas Medline via Pubmed, Scientific Electronic Library Online, Literatura Científica e Técnica da América Latina e Caribe, Biblioteca Virtual em Saúde. A nova classificação das doenças periodontais incluiu ferramentas para uma avaliação individual do paciente, reconhecendo fatores de risco que possam interferir negativamente na resposta ao tratamento. A ocorrência de descontrole metabólico em pacientes periodontais com diabetes mellitus tipo 2, passa a ser considerada, então, um fator de grande importância para a avaliação da susceptibilidade individual para a progressão da periodontite. Acredita-se que o diabetes promova uma resposta hiperinflamatória ao desafio bacteriano, modificando a resposta tecidual dos tecidos periodontais.
