Cone Beam Computed Tomography Assessment of Accessory Infraorbital Foramen and Determination of Infraorbital Foramen Position.

There is no evidence about evaluating accessory infraorbital foramen by 3-dimensional analysis like multi slice computed tomography or cone beam computed tomography (CBCT) in human subjects. To authors' best knowledge this is a first study to assess the accessory infraorbital foramen and position of infraorbital foramen in relation to crown of maxillary teeth using CBCT. This study primarily aimed to assess the location and number of accessory infraorbital foramen (AIOF), to measure the distance between main infraorbital foramen and AIOF and secondarily to determine the position of infraorbital foramen in relation to crowns of maxillary second premolar, first molar, and second molar. Cone beam computed tomography volumes of 200 patients were retrieved from the digital imaging and communications in medicine archive folder. Accessory infraorbital foramen was recognized in 29% of the patients among whom 46.6% were present on the right side, 31% on the left side, and 22.4% located bilaterally. The most frequent position of infraorbital foramen was found to be in line with crown of second premolar. The presence of AIOF and inability to recognize it in preoperative evaluation could be considered among the other reasons of failure or incomplete anesthesia.

Comparison between Palpation and Superficial Marking Techniques in Determining Infraorbital Foramen in Chinese Women

Background : Difficulties in determining infraorbital foramen were often found in anesthesia procedures, reconstruction surgery, acupuncture, and botox insertion. The most common technique used is palpation technique. However, there are some disadvantages in this technique.The aim of this study was to establish a new superficial marking technique to determine the position of infraorbital foramen by making a horizontal imaginary line from the top part of nose wings. Methods : This study was an analytical cross-sectional study conducted at the Faculty of Medicine, Universitas Padjadjaran in Jatinangor-Sumedang during the period of April to November 2012. A total of thirty Chinese female students were assessed to measure the mean distance between the inferior orbital margin to the infra orbital foramen and inferior orbital margin to horizontal imaginary line from the top part of nose wings. The differences were then checked using paired t-test. Results : There was a significance difference between the mean distance of the inferior orbital margin to the infra orbital foramen and the inferior orbital margin to the horizontal imaginary line from the top part of the nose wings on the right and left face of Chinese women with p<0.05 (p=0.000). Conclusion : Infra orbital foramen cannot be determined by using superficial marking technique in Chinese women.

Morphometric analysis and anatomical variations of infraorbital foramen: A study in adult North Indian population

Various studies have been conducted on morphometric variations of infraorbital foramen to provide data to surgeons for nerve block in infraorbital region. This study aims to analyse the anatomical variations by comparing various morphometric measurements of infraorbital foramen in dry skulls of adult North Indian population. This study becomes relevant in the present study group as very scant data is available about the variations and morphometric measurements in Indian population. The data thus collected can be standardized and become useful for the surgeons working in this area of face. The study was conducted on 75 dry adult human skulls, which were a part of Department of Anatomy, used for teaching purposes in medical colleges. Straight distance of the Infraorbital foramen from the infraorbital rim, supraorbital foramen and sagittal plane was measured. The position of the infraorbital foramen was determined in relation to maxillary teeth and supraorbital foramen. The data thus obtained was analysed. The distance of infraorbital foramen from infraorbital rim, supraorbital foramen, sagittal plane in the present study was found to be 6.71 ± 1.11 mm, 42.02 ± 4.31 mm and 31.94 ± 4.88 mm respectively. The position of infraorbital foramen was lateral in relation to supraorbital foramen (in 88% of cases). Infraorbital foramen was above the 1st premolar tooth in most of the cases. Accessory infraorbital foramen was found in 11.2% cases (double foramen). The data thus obtained will perhaps be helpful to the surgeons in identifying the extent of the operative field thereby reducing procedural risks.

Infraorbital foramen - Morphometric study and clinical application in adult Indian skulls

Background: Infraorbital foramen is an important site for various surgical and anesthetic procedures. Accurate localization of the foramen holds the key to success, although racial variations exist in various population groups. Aims: To study the morphometry of infraorbital foramen and its location with respect to nearby anatomical landmarks. Materials and Methods: A total of 100 dry skulls (60 male and 40 female) were collected and observed for the study. Various parameters in the sagittal and transverse planes were noted from infraorbital foramen on both sides, together with its vertical and horizontal dimensions. In addition, the location of infraorbital foramen with respect to upper tooth and presence of any accessory foramina were noted. Results: We measured 198 sides in 100 Indian skulls. The most common position of infraorbital foramen was observed to be in line with second premolar tooth (64%). The mean distance from infraorbital foramen to infraorbital margin was 7.65 ± 1.35 mm on the right side and 7.11 ± 1.73 mm on the left side and from infraorbital foramen to lower border of alveolus of maxilla on the right and left sides (25.98 ± 1.89 and 25.27 ± 2.17 mm; P = 0.01). Conclusions: This study makes possible the identification of exact position of infraorbital foramen and its application in various surgical procedures.
