The infraorbital foramen lies on the anterior aspect of the maxilla bone and is approximately 1 cm below the midpoint of the infraorbital margin
(Figure 1(a) and Table 1) .
The 3-D computed tomography (CT) examination showed that the body of the maxilla on right side along with lateral border of pyriform aperture and medial infraorbital margin
was missing (Figures 2 and 3).
The aim of this study was to locate the IOF in relation to the infraorbital margin
(IOM) and the alveolar bone process of the maxilla at the second premolar for proper injections of local anesthetics, as well as to determine the depth of needle penetration into the pterygopalatine fossa through GPC to avoid serious complications following nerve block anesthesia.
Three point fixations were achieved in group B by application of the fixation device at fronto-zygomatic, zygomatic buttress and infraorbital margin
. The observer did not know about the kind of therapy applied at the time of the patient examinations.
It extended superiorly to the infraorbital margin
, medially to the alae of the nose, and laterally to 2 cm anterior to the pre-auricular region with an indistinct inferior margin.
Measurements of facial soft tissues of northwest Indian men were higher than northwest Indian women except beneath the chin, infraorbital margin
, and lower lip margin.
The infraorbital foramen (IOF) is located on the maxillary bone about 1cm inferior to the infraorbital margin
In a previous study by Ikiz (1999) on skulls of the Byzantine period only, an investigation was made of the position of the infraorbital foramen relative to the supraorbital foramen, and also of its distances from the infraorbital margin
and from the midsagittal line.
Four parameters including transverse diameter and vertical diameter of infraorbital foramen and its distances from the infraorbital margin
and nasal notch, were considered.
Digital paquimeter was used and had been carried through two bilateral measures: a)sagittal measure; from infraorbital margin
until the superior margin of the IOF; b) transversal measure, of the lateral margin of piriformis opening until the medial margin of the IOE using the transversal plan.
b) Orbital height (Lo): The perpendicular distance between the supraorbital and infraorbital margins
of the orbit.
a) Orbital length: The perpendicular distance between the supraorbital and infraorbital margins
of the orbit.
