RESUMEN
Knowledge of the Eagle's syndrome shows that its symptoms can be very easily confused with other types of craniomandibular disorders, especially temporomandibular disorders (TMD). The aim of this study was to find a possible correlation between the presence of TMD and elongation of the styloid process as well relate to presence of calcification of the stilohyoid chain. Fifty patients with TMD, confirmed from the RDC/TMD, were examined clinically and radiographically. Radiographic documentation consisted of digital panoramic radiograph and digital lateral cephalometric radiograph. Radiocef software (Radiomemory) was used for the analysis of radiographs by means of specific cephalometric tracing and linear measurements of the styloid process. Each radiograph was traced and measured three times with intervals of 1 month to spread the error. Statistical analysis was performed by Pearson's test (p=0.001) using Biostat 4.0 statistical software. Result showed an incidence of 76% elongation of the styloid process in the sample. There was a correlation between the bilateral measures taken in panoramic radiographs (?<0.001) and also for measures of styloid process length carried out in different panoramic radiographs and lateral cephalometric radiographs (?<0.001). It was concluded that there is prevalence of elongated styloid process in patients with TMD. However, no relationship was found between measurements on the stylohyoid chain and symptoms of headache, orofacial pain, tinnitus and vertigo.

O conhecimento adquirido sobre a síndrome de Eagle demonstra que sua sintomatologia pode ser confundida muito facilmente com outros tipos de desordens craniomandibulares, principalmente a disfunção temporomandibular (DTM). O objetivo do estudo foi encontrar uma possível correlação entre a presença de DTM e o alongamento do processo estilóide, assim como a relação com a calcificação da cadeia estilo-hiódea. Para tanto foram analisados 50 pacientes com DTM, confirmada a partir do RDC/TMD. Foi realizado o exame clínico e documentação radiográfica de cada paciente, composta por: radiografia panorâmica digital e cefalométrica lateral digital. Para a análise das radiografias foi utilizado o programa computacional Radiocef (Radiomemory), onde foram realizados traçados cefalométricos por análise específica e medidas lineares do processo estilóide. Cada radiografia foi traçada e medida por três vezes, com intervalos de tempo de 1 mês entre as medições a fim de diluir o erro. Foi realizada a estatística através do Programa Biostat 4.0 e o teste de Pearson (?=0,001). Como resultado foi encontrada uma incidência de 76% de alongamento do processo estilóide na amostra. Houve correlação positiva para as medidas bilaterais realizadas na radiografias panorâmicas (?<0,001) e também para as medidas de comprimento do processo estilóide realizados nas diferentes tomadas radiográficas panorâmicas e cefalométricas laterais (?<0,001). Concluiu-se que há prevalência de alongamento do processo estilóide em pacientes com DTM, embora não tenha sido encontrada relação entre as medidas realizadas na cadeia estilo-hióidea com os sintomas de cefaléia, dor orofacial, zumbido e vertigem.
