Previous issue date: 2014-03-28 / Ultrasonography is an innocuous noninvasive diagnostic tool, which is easy to perform and low-cost, and it is widely used in the medical field, indicated especially in the exam of soft tissues. Despite this, it is not usually requested by dental surgeons in the diagnostic investigation of intraoral lesions. The aim of this study was to determine how much this resource contributes to establishing the final diagnosis of nodules located in the oral and maxillofacial region. Accordingly, we evaluated the indication of use and reliability of the procedure in Dentistry, considering the usefulness to reach the definitive diagnosis of these alterations. Sixty-five patients with submucosal or subcutaneous nodules were recruited for the study. They had been indicated for and subjected to regional ultrasonography, since it was not possible to establish a conclusive diagnosis of the lesions only by clinical examination. Ultrasonography was carried out in an imaging diagnostic center utilizing the same apparatus Toshiba Aplio 80 Japan. The imaging reports were prepared by a single examiner, with wide experience in the interpretation of images of the oral and maxillofacial region. Of the total patients, 43 had a biopsy for histopathologic confirmation of the final diagnosis. In 22 individuals, it was not necessary to perform surgery, since imaging allowed the establishment of the diagnosis and management of the patient. Two investigators evaluated the results obtained with ultrasonography and estimated the scores, which were zero (ultrasonographic diagnosis differed from the final), 1 (contributed to the management of the patient) and 2 (defined the definitive diagnosis). The zero score accounted for 12.3% of the examinations performed, while 41.5 and 46,1% of patients had scores of 1 and 2, respectively, totaling 87.6% of cases where imaging was helpful. The procedure facilitated the diagnosis of vascular lesions in 93.3%, helped with the management of 87.5% of patients with both malignant and benign neoplasms, and had a role in establishing the final diagnosis in 76.5% of cases of mucus retention phenomena. The results obtained were in accordance to findings in the literature, which demonstrated that ultrasonography is an effective resource in determining the final diagnosis or in the management of patients with nonspecific nodular lesions in the soft tissues of the oral and maxillofacial region / A ultrassonografia ? uma ferramenta de diagn?stico in?cua, n?o invasiva, de f?cil acesso e baixo custo utilizada amplamente na ?rea m?dica, indicada, em especial, no exame dos tecidos moles. Apesar disto, n?o costuma ser solicitada pelos cirurgi?es dentistas, durante a investiga??o diagn?stica de les?es intraorais. O objetivo desta pesquisa foi verificar o grau de contribui??o que o recurso fornece no estabelecimento do diagn?stico final de n?dulos localizados na regi?o bucomaxilofacial. Buscou-se estabelecer a indica??o de uso e confiabilidade do m?todo na ?rea da Odontologia, considerando a possibilidade do mesmo favorecer ou n?o o diagn?stico conclusivo destas altera??es. Foram selecionados 65 pacientes portadores de n?dulos submucosos ou subcut?neos, que tiveram a indica??o e foram submetidos ? ultrassonografia regional, uma vez que n?o foi poss?vel estabelecer o diagn?stico conclusivo das les?es exclusivamente atrav?s do exame cl?nico. A ultrassonografia foi realizada em um centro de diagn?stico por imagem utilizando o aparelho Toshiba Japan modelo Aplio 80. Os laudos foram emitidos por um ?nico examinador, com ampla experi?ncia na interpreta??o de imagens da regi?o bucomaxilofacial. Do total de pacientes, 43 foram submetidos ? bi?psia tendo o exame histopatol?gico para confirma??o do diagn?stico final. Em 22 indiv?duos n?o foi necess?ria a execu??o do procedimento cir?rgico, uma vez que o exame de imagem permitiu o estabelecimento do diagn?stico e manejo do paciente. Dois pesquisadores avaliaram os resultados obtidos na ultrassonografia e estabeleceram escores, que variaram entre zero (onde significou que o diagn?stico ultrassonogr?fico diferiu do final), 1 (contribuiu no manejo do paciente) e 2 (definiu o diagn?stico conclusivo). O escore zero, representou 12,3% dos exames realizados, entretanto os escores 1 e 2 computaram respectivamente 41,5% e 46,1%, totalizando um percentual de contribui??o equivalente ? 87,6%. O m?todo favoreceu o diagn?stico das les?es vasculares em 93,3% e no manejo das neoplasias, tanto malignas quanto benignas, em 87,5%. Nos fen?menos de reten??o de muco participou no estabelecimento do diagn?stico final em 76,5%. Os resultados obtidos foram ao encontro dos achados na literatura, os quais demonstraram que a ultrassonografia ? um recurso eficaz na determina??o do diagn?stico final ou no manejo dos pacientes, portadores de les?es nodulares inespec?ficas dos tecidos moles da regi?o bucomaxilofacial.
