Las órbitas óseas son cavidades del esqueleto situadas a cada lado de la nariz. Se conocen las diferencias raciales en las medidas orbitales. El objetivo del presente estudio era determinar las distancias de varias fisuras y foramen en la órbita en relación a ciertos puntos de referencia óseos / quirúrgicos sobre los márgenes orbitales en la población india, lo que puede ser útil durante la cirugía orbital. La distancia de canal óptico (OC), fisura orbitaria superior (SOF), fisura orbital inferior (IOF) y forámenes lagrimales (LF) se mide a partir de puntos de referencia como cresta lacrimal anterior (ALC) para la pared medial, muesca/foramen supra orbital (SN) para la pared superior, sutura cigomática frontal (FZ) de la pared lateral y un punto en el margen inferior (OIM) justo encima del agujero infraorbitario. Se midió la distancia del foramen etmoidal anterior y posterior (AEF y PEF) de ALC. Se observó la presencia de foramen etmoidal media (MEF) y forámenes lagrimales (LF).La distancia media de OC fue 39,71 ±2,67 mm(deALC), 45,11 ±3,4 mm(de SN) , 48,32 ±2,8 mm(de FZ ) y 45,97 ±3,9 mm(de OIM). La distancia segura para el nervio óptico para cada pared orbital se calcula restando5 mmde la distancia más corta medida.
The bony orbits are skeletal cavities located on either side of the nose. Racial differences in orbital measurements are known. The aim of the present study was to determine the distances of various fissures and foramen in the orbit with reference to certain bony / surgical landmarks on the orbital margins in Indian population which can be useful during various surgical procedures. The distance of optic canal (OC), superior orbital fissure (SOF), inferior orbital fissure (IOF), lacrimal foramen (LF) were measured from landmarks like anterior lacrimal crest (ALC) for medial wall, supraorbital foramen/ notch (SON) for superior wall, fronto-zygomatic suture (FZ) for lateral wall and a point on inferior margin (IOM) just above the infraorbital foramen. Distance of anterior and posterior ethmoidal foramen (AEF and PEF) from ALC was measured. The incidence of middle ethmoidal foramen (MEF) and lacrimal foramen (LF) was noted. The mean distance of OC was 39.71 ±2.67 mm(from ALC), 45.11 ±3.4 mm(from SN), 45.97 ±3.9 mm(from FZ) and 48.32 ±2.8 mm(from IOM). The safe distance for optic nerve for each orbital wall was derived by subtracting5 mmfrom the shortest measured distance.
