“…Our study concluded that the MF is located at an average distance 15.2 mm and 12.6 mm from the IBM in dentate and edentulous mandibles, respectively. Considering the mean values for the distance MF-IBM in dentate mandibles, the results of the present study in Greeks were similar to that observed for Africans, Chinese and Thais [3,33] and higher than that related for British, Koreans and Americans [7,8]. The studies of Güler et al [13], Apinhasmit et al [3] and Amorim et al [2] reported a gender dimorphism, as the male mandibles of their sample presented higher values of MF-IBM distances than the female.…”

Background: The knowledge of the exact location of the mental foramen (MF) in dentate and edentulous mandibles is clinically important when constructing complete dentures, performing anaesthetic block of the lower-anterior teeth area and intervening in the MF nearby area. In edentulous mandibles, the bone resorption after teeth loss makes the mental nerve (MN) prone to damage due to the extreme location of the MF very close to the alveolar crest (AC). Chronic compression on the MN may result in pain in the area of MN distribution (ipsilateral face and cheek area) and numbness at the lower lip. The purpose of the current study is to evaluate the exact position of the MF, calculating the distances MF-superior border of the AC and MF-inferior border of the mandible (IBM) in (p = 0.39 and p = 0.45). Conclusions:The MF is an important landmark and its location needs to be considered prior to dental implants placement in order to avoid the MN injury and related complications. The position of MF is altered in edentulous mandibles compared with the dentate ones. The MF is a symmetric structure in Greeks. (Folia Morphol 2017; 76, 4: 709-714)

“…The study of the Infra orbital foramen is also basic to prevent the potential risk for iatrogenic injury during facial surgeries due to the presence of additional branches of the infra orbital nerve [19]. Previous studies show the relation between infra orbital foramen and the other anatomical structures, in studies with different purposes, what shows its importance as a repair point: distance between infra orbital foramen and an imaginary horizontal line in the piriform aperture base, inferior orbital fissure and the more inferior portion of the optical channel [21] medium facial line on an imaginary line that passes through the supraorbital incisure; eyes pupil and second premolars [22] medium sagittal plane and supraorbital incisures [23] and finally related to the piriform aperture [19]. The morphometric and morphological studies of foramens of skull and different bones of skull are more helpful in surgery practice and anthropometric studies [24,25].…”

“…The location of this foramen determines morphometric variations from reference points to decrease the risk of orbital surgery [7]. The morphometry of this foramen plays an important role during regional block anesthesia techniques of the infraorbital nerve [8,9]. The precise location of the foramen facilitates risk free zygoma fracture surgery [10].…”

Background: The infraorbital foramen is located on the maxillary bone about 1 cm inferior to the infraorbital margin. The infraorbital nerve and vessels are transmitted through this foramen. The infraorbital nerve, the continuation of the maxillary or second division of the trigeminal nerve, is solely a sensory nerve. It traverses the inferior orbital fissure into the inferior orbital canal and emerges onto the face at the infraorbital foramen. It divides into several branches that innervate the skin and the mucous membrane of the midface, such as the lower eyelid, cheek, lateral aspect of the nose, upper lip, and the labial gum.

“…Several studies has been evaluated morphometric assessment of the IOF (Gruber, 1878;Gozdziewski et al, 1979;Bolini & Del Sol;Triandafilidi et al;Ochs & Buckley, 1993;Chapman et al,1995;Chung et al, 1995;Leo et al, 1995;Aziz et al;Karakas et al, 2002), nevertheless, the results presented large variance. This foramen has been used from various reference points, e.g.…”

SUMMARY:The aim of the study was to establish morphometrically the infraorbital foramen (IOF) location in the sagittal and transversal plan of the skull and to analyze the variations, as well as verifying the symmetry with the contralateral IOF. 210 skulls were analyzed and as exclusion criterion, were not analyzed skulls of children. 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 IOF, using the transversal plan. These measures had formed an angle of 90º between itself. The data were analyzed by the Kolmogorov-Smirnov to verify the Gaussian distribution and and Person's test to evaluate the correlation, considering significantly the differences that had presented a p≤ 0,05. The mean±SD in the sagital measures were respectively; right side 6,71±1.70 mm and 6,83±1.83 mm for left side (p≤0.0001). Transversal measures were: right side 13,28±2.17mm and 13,31±2.19 mm for left side (p≤0.0001). Were observed supranumerary foramens of the IOF, with presence of the double IOF in 50 cases, being bilateral in 08 specimens, left and right side 21 specimens for each side.The IOF are not absolutely symmetrical and may present pair bilateral and or unilateral opening. The presence of the supranumerary foraminas, as well as, the morphometrics measures in this study may intervene with the anesthesia, thus, suggest that they must be considered in the anaesthesical evaluation and be remembered during the procedures used for the localization of the forame. (Chonghuo, 1993;Chen, 1997;Esper et al. 1997Esper et al. ,1998, require more precise understanding of the surrounding anatomy (Bolini & Del Sol; Karakas et al.). Data on morphometric measurements regarding reference points should reduce risks during procedures, surgical operations and anesthesia (Zide & Swift; Karakas et al.; Du Tolt & Nortje). Therefore, the purpose of this study was to conduct morphometric measurements of the IOF location by using the sagittal and transversal plan of the Brazilian skull as reference, as well as verifying the symmetry with the contralateral IOF.Exclusion criterion of the sample: It was adopted like exclusion criterion all the child skulls and the skulls which the piriformis opening was damaged, unilaterally or bilaterally.In all the samples the presence of right maxilar joined to the left maxilar was considered indispensable to have the absolutely certainty that the studied foramens belonged to the same original skull and the statistic could express reliable results. The variables age, sex and race were not considered. Statistical analysis:The softwareGraph Prism was used in the statistical evaluation of measurement results. From these measurements means and standard deviations (mean±SD) were calculated. The data were analyzed by the KolmogorovSmirnov to verify the Gaussian distribution and and Person's test to evaluate the correlati...
