Abstract in Portuguese
Neste estudo avaliou-se a eficácia da radiografia panorâmica na detecção de desvio do septo nasal. Para tanto, utilizou-se como padrão ouro o exame clínico e imagens tomográficas da face. A amostra foi composta por imagens radiográficas panorâmicas e por imagens de tomografia computadorizada da face de 70 indivíduos. Dentre os indivíduos que compuseram o estudo, 30 eram pacientes que seriam submetidos a tratamento odontológico e possuíam radiografias panorâmicas nas quais foram observadas imagens compatíveis com desvio do septo nasal. Estes pacientes foram avaliados por um otorrinolaringologista e submetidos, segundo o critério da justificação, ao exame de tomografia computadorizada da face. Os outros 40 indivíduos foram selecionados a partir de imagens panorâmicas dos prontuários de pacientes disponíveis no arquivo da Clínica de Estomatologia da FOB-USP e que também haviam realizado tomografia computadorizada da face para elaboração de diagnóstico e plano de tratamento odontológico. Os resultados mostraram que a radiografia panorâmica, segundo a metodologia adotada, foi eficaz na detecção do desvio do septo nasal, com 100% de Especificidade. Além disso, este exame permite a confirmação da ausência deste desvio na maioria dos casos, com 86% de Sensibilidade.

Abstract in English
OBJECTIVE: Discern the efficacy of panoramic radiography on nasal septum deviation. Gold standard computerized tomography along with clinical examination was used for comparison. MATERIAL AND METHODS: Sample was composed of 70 subjects from Stomatology files of FOB-USP. Nasal septum deviation was assessed using the panoramic radiographies. Then, computerized tomography was analyzed and the results confronted. RESULTS: Images of nasal septum deviation were observed and confirmed in both exams on 100% of the subjects. However, in those cases with no deviation observed with the panoramic radiographies, its presence was confirmed in 86% after computerized tomography. CONCLUSION: Panoramic radiography was trustable for confirmation of nasal septum presence, with 100% of Specificity. Further, this exam allows the confirmation of the absence of this deviation in the majority of cases, with 86% of Sensibility.
