Thin section computed tomography in the evaluation of naso-ethmoidal trauma

Complicaciones en pacientes operados de reducción de fracturas naso-órbito-etmoidales de acuerdo con la clasificación de Manson y Markowitz

“…La diplopía puede ser otra secuela de fracturas tipo NOE y puede ocurrir debido al desplazamiento lateral de los fragmentos de la pared orbital medial hacia la órbita o el desplazamiento medial del hueso etmoidal, tal como lo demostró Lamb, en 1990, después de la revisión de los resultados de 33 pacientes que presentaron trauma facial, mediante TC, de los cuales el 51% correspondió a fracturas tipo NOE, encontrando diplopía por desplazamiento lateral y medial en el 35 y 12% respectivamente. [29][30][31] También pueden ocurrir deficiencias visuales y ceguera. 20,[32][33][34] Ansari, en su estudio retrospectivo de 19 años, informó sólo un caso de ceguera entre 19 pacientes con fracturas NOE, 33 que es el tipo de fractura facial que involucra menos lesiones oculares.…”

Ultrasonography in the diagnosis of nasal bone fractures: a comparison with conventional radiography and computed tomography

“…However, unlike injuries on the midline of nasal bone, it is difficult to evaluate lateral nasal wall injuries on conventional radiographs [1,15,16]. Furthermore, several studies have demonstrated that conventional radiography cannot be used routinely to evaluate nasal bone fractures [1,10,17]. Previous studies showed that the sensitivity of conventional radiography in detecting fracture line of nasal bone is 79 % [18].…”

“…Although HRUS is the diagnostic technique of choice when fractures are confined to the nasal bone [22], CT may precisely depict anatomic details of nasal bone and soft tissue, and produce images showing the position and orientation of displaced fractures [10]. Accordingly clinicians frequently find it easier to interpret CT scans than US [17]. However, CT is not always sufficient, and fine nasal fracture lines can be missed due to the partial CT computed tomography, Op operative findings, Plain plain radiography, US ultrasonography Eur Arch Otorhinolaryngol volume artifacts or the direction of fracture or faint fracture [10].…”

Comparison of High-Resolution Ultrasonography and Computed Tomography in the Diagnosis of Nasal Fractures

“…Clinicians frequently find it easier to interpret a CT scan than a sonogram. 10 However, CT findings alone are not always adequate. A fracture line can be missed on a CT scan because of the partial volume effect, and a slightly depressed nasal fracture is more easily diagnosed on a conventional lateral view than on a CT scan.…”
