The present study concluded that the application of dexamethasone in the masseter muscle effectively reduces edema and trismus, but does not affect pain.
Objective: The objective of this research was to review the literature, compare different methods of surgical treatment for coronoid hyperplasia and report a clinical case of unilateral coronoid hyperplasia treated by coronoidectomy with intraoral access. Methods: A critical review of the literature was performed by selection of papers published in the last 20 years on the treatment of coronoid in adults in the PubMed, Medline, Scielo and Lilacs databases, with the terms coronoid hyperplasia OR coronoid elongation AND treatment OR management. The data was extracted for analysis. Results: twenty-four articles were selected. It included 42 patients, among them 69% were male patients and 81% were bilaterally affected. The age group with the highest prevalence was the people in the 20's and 30's. Sixty-nine percent of the patients were treated with coronoidectomy and 26.2% with coronoidotomy. The majority (83.3%) with intraoral access. No cases had surgical complications reported, and 71.4% underwent physiotherapy after surgery. Regarding the results, 83.3% were considered satisfactory, 11.9% were unsatisfactory. Conclusion: The great majority of the cases that brought significant results in the improvement of the pre and postoperative mouth opening were treated by coronoidectomy, proving to be an efficient and safe surgical treatment for the coronoid hyperplasia.
Este caso clínico relata tratamento cirúrgico em paciente idosa desdentada bimaxilar após trauma em terço inferior de face. A paciente compareceu a emergência do Hospital de Fraturas, Recife – PE com queixa de dor em face após queda da própria altura. Ao exame radiográfico, constatou-se fratura mandibular bilateral. O planejamento do tratamento foi realizado levando em consideração alguns fatores importantes para o sucesso terapêutico, como uso de medicamentos, presença de doenças crônicas e alterações fisiológicas e anatômicas. Após o diagnóstico e correto planejamento, foi realizada a fixação dos cotos ósseos com 2 miniplaca do sistema 2.0. A paciente evoluiu bem, sem queixas, sem parestesia ou paralisia, e a radiografia pós-operatória demonstrou boa redução das fraturas. Dessa forma, conclui-se que o tratamento dos traumas em pacientes idosos pode ser através de métodos conservadores ou de técnicas mais complexas e invasivas, levando-se sempre em consideração o caso particular do paciente, visando suas necessidades e implicações específicas.
Objective
The aim of the present study was to locate mast cells in chronic periapical lesions (granulomas and cysts) by using histochemical techniques and toluidine blue staining.
Methods
RESUMO ObjetivoLocalizar mastócitos em lesões periapicais (granulomas e cistos) através de técnicas histoquímicas e corante azul de toluidina.
MétodosUma pesquisa quantitativa, descritiva, transversal e retrospectiva foi realizada. As amostras foram obtidas de documentos histopatológicos nos arquivos do laboratório de patologia cirúrgica da Universidade de Pernambuco entre Novembro de 2014 e Março de 2015.
ResultadosDezesseis casos de granuloma e 21 casos de cistos periapicales foram selecionados. As lâminas coradas foram analisadas por dois examinadores em tempos diferentes, em um estudo duplo-cego. Mastócitos foram encontrados em 13 (61,9%) dos casos de cistos periapicales, localizados na cápsula da lesão. Nos granulomas periapicais, mastócitos foram encontrados em oito casos (50%), localizados no tecido de granulação.
ConclusãoMastócitos foram detectados tanto em cistos quanto em granulomas periapicais, localizados na cápsula e no tecido de granulação respectivamente. Os mastócitos estavam mais presentes nos cistos do que nos granulomas periapicais.
Propose:
This paper aims to describe a modification of the Wolford technique by replacing the Mitek anchors with bone screws.
Technical description:
Two intermaxillary fixation screws locking screws, with 2.0 mm in diameter and 8 mm in length, are used in each temporomandibular joint, one of which is fixed to the root of the zygomatic arch and another to the lateral pole of the mandibular condyle. Ethibond 2-0 thread is passed through the holes in the 2 ipsilateral screws, thus acting as an artificial ligament limiting the range of the mouth opening.
Conclusion:
The technique described was effective in preventing mandibular dislocation while allowing satisfactory mouth opening range. This technique has easy handling and low cost.
