RESUMEN
La hipertrofia del proceso coronoides mandibular es una patología rara, progresiva y de etiología desconocida, que se caracteriza por el desarrollo exagerado del proceso coronoides determinando aumento en su tamaño, resultando en una progresiva y dolorosa limitación de la apertura bucal. La hipomovilidad mandibular es un síntoma presente en diversas enfermedades y asociarla a una causa específica requiere exámenes clínicos e imagenológicos minuciosos. La tomografía computarizada cone-beam tiene el potencial de ofrecer informaciones complementarias superiores a las radiografías convencionales. Además, elimina superposiciones, ofrece alta resolución de imagen, lo que ayuda no solo el diagnóstico, sino también la planificación del procedimiento quirúrgico. Presentamos un caso de paciente de sexo masculino que acudió a la consulta para evaluación de trismus. No presentaba dolor, solo incomodidad por limitación progresiva de apertura bucal. Mediante el examen físico, solo se observó la limitación de apertura bucal. Aunque los movimientos de lateralidad y protrusión eran posibles, estaban muy limitados. Se realizó examen de tomografía computarizada cone-beam, que evidenció imagen compatible con hipertrofia bilateral del proceso coronoides mandibular.
ABSTRACT
The hypertrophy of the mandibular coronoid process is a rare condition, progressive and of unknown etiology, characterized by the over development of the coronoid process determining their size increased, resulting in progressive and painful limitation of mouth opening. The mandibular hypomobility is a present symptom in several diseases and associates it to a specific cause requires detailed clinical and imaginologic examination. The cone-beam computed tomography has the potential to provide complementary informations above than conventional radiography. It also has the advantage of eliminate overlaps, provide high resolution image, helping not only in diagnosis, but also in planning the surgical procedure. Here we report a case of male patient, who appeared at the clinic for an evaluation of a trismus. He had no pain, only discomfort for progressive limitation of mouth opening. On physical examination, only a limited mouth opening has been found. Although the movements of laterality and protrusión were posible, they were very limited. Cone-beam computed tomography examination was performed, that showed an image compatible with bilateral hypertrophy of the mandibular coronoid process.
