“…The above finding is in consistence with previous reports. 4,12,14,15 Also, this study identifies medially directed infraorbital foramen which was in accordance with other reports. 16,17 The mean distance between infraorbital foramen and infraorbital ridge in this study was 6.7 mm in male skull and 6.2 mm in female skull for left infraorbital foramen and was 6.3 mm in male skull and 6 mm in female skull for right infraorbital foramen.…”

“…The left transverse diameter was 3.7 mm in male skulls and 3.0 mm in female skulls with significant difference among genders. Previous studies 4,14,16,21,22 were recorded figures close to the findings of this study. However, Oliverira et al 20 recorded larger transverse diameter 4.2 mm on right side and 4.33 mm on left side.…”

“…This is in accordance with Aziz et al 7 whereas some studies 4,13,14 disagreed with the finding of this study as they reported that the common position of infraorbital foramen was in line with second upper premolar tooth but the next frequent position was line between first and second premolar.…”

“…This is in accordance with other studies. 14,16,[20][21][22] But larger distance was recorded by Aziz et al 7 The mean distance of right transverse diameter of infraorbital foramen was 3.3 mm in male skull and 3.0 mm in female skulls with no significant difference between the genders. The left transverse diameter was 3.7 mm in male skulls and 3.0 mm in female skulls with significant difference among genders.…”

Objectives: Evidence supports a clear racial variation in the position of the infraorbital foramen (IOF). Therefore detailed knowledge of the population specific data on biometric features of (IOF) will facilitate therapeutic, diagnostic and surgical manipulations in the maxillofacial region. The goal of this study was to elucidate the morphological features and precise anatomical position of the (IOF) with reference to surrounding anatomical landmarks in an adult Egyptian population. Materials and methods:Fifty-nine adult dry Egyptian skulls (32 males and 27 females) were assessed to determine the number, shape, orientation, vertical and transverse diameters of the IOF, transverse distance from the IOF to the maxillary midline, the zygomaticomaxillary suture and the vertical distance from the IOF to the infraorbital rim and accessory infraorbital foramen using a metal casting digital vernier caliper. The position of the IOF was determined in relation to the maxillary teeth. The findings indicated that the size of the IOF and the mean distances from the IOF to the maxillary midline, infraorbital rim and foramen was significantly larger in males than in females. Results:The majority of IOF among the skulls were semilunarshaped in 59.4% in male skulls and 48.1% in female skulls. The majority were directed inferomedially in 88.9% in female skulls and 78.1 % in male skulls. Accessory foramina were found in 21.87% of male skulls and 18.5% of female skulls. All had bilateral double foramina except for one male skull and one female skull. Conclusion:The racial and gender differences of the IOF emphasize the need for meticulous preoperative evaluation of the IOF in patients who are candidates for maxillofacial surgeries and regional block anesthesia.

“…Significant variations have been reported in the literature with regard to the position of IOF in relation to the infraorbital margin [3, 5, 6, 8, 14]. Moreover, the position of IOF in relation to maxillary teeth has been shown to vary among population groups [3, 13, 21]. …”

The present study was conducted to ascertain the shape, size, presence of accessory foramina, direction, and the precise position of the infraorbital foramen (IOF) in relation to the inferior orbital margin (IOM), anterior nasal spine (ANS), nasion (Na), maxillary teeth, and supraorbital foramen/notch (SOF/N) in adult skulls in a Sri Lankan population. Fifty-four skulls (42 males and 12 females) were analyzed. The IOF was oval in shape (38.6% and 36.3% on the right and left side, resp.) in a majority of skulls. The direction of the IOF was mostly medially downward (48.6%). Accessory foramina were found in 7.4% of the skulls. The infraorbital foramina were located at a mean distance of 6.52 ± 2.03 mm and 7.30 ± 1.57 mm, vertically below the IOM on the right and left side, respectively; 33.81 ± 2.68 mm and 34.23 ± 2.56 mm from the ANS on the right and left side, respectively; and 42.37 ± 3.52 mm and 42.52 ± 3.28 mm from the Na on the right and left side, respectively. In relation to the upper teeth the majority of IOF (37.5% and 55.9% on the right and left side, resp.) were located in the same vertical axis as the tip of the buccal cusp of the maxillary second premolar tooth.

Detailed knowledge of variations of the infraorbital foramen (IOF) and the establishment of a constant reference point for needle insertion are important for safe and successful regional block and for avoiding iatrogenic injury to the nerve during surgery in the midfacial region. Infraorbital foramina from 133 sides of 67 dry intact adult skulls of undetermined gender were examined for variations in shape, number, location in relation to bony landmarks, and relationship to the maxillary teeth. The angles of needle insertion in the sagittal and Frankfurt planes were determined. The infraorbital foramina were located at an average distance of 6.33 ± 1.39 mm below the infraorbital margin, 25.69 ± 2.37 mm from the median plane, 15.19 ± 1.70 mm from the lateral margin of the piriform aperture, and 28.41 ± 2.82 mm above the maxillary alveolar border. The average angles of needle insertion through the IOF with the sagittal and Frankfurt planes were 21.14° ± 10.10° and 31.79° ± 7.68°, respectively. Multiple foramina were found in 21% of the hemi-skulls. The foramen was less than 2 mm in size in 23.31% of the hemi-skulls. The position of the IOF with respect to the maxillary teeth varied from the interval between the canine and first premolar to the first molar, but in half of the specimens it lay in line with the second maxillary premolar tooth. The observations made in this study should be useful for planning infraorbital nerve block or surgery around the IOF.
