ABSTRACT Objective To study the localization and relative of the supratrochlear, supraorbital, infraorbital and mental foramen in Thai cadavers to external landmarks for helps the surgeon to easily and practically identify these foramen. Materials and methods The localization of the supratrochlear, supraorbital, infraorbital and mental foramen in adult Thai cadavers were studied in 110 cadevers (220 sides) from 2008 until 2012. The analyses were also performed to compare differences between sexes and sides. Results Mean length of supraorbital foramen from nasal midline on the right side was 2.76 cm, left side 2.75 cm, above supraorbital rim right side 0.23 cm, left side 0.23 cm. Mean length of supratrochlear foramen from nasal midline on the right side was 1.77 cm, left side 1.76 cm. Mean length of infraorbital foramen from maxillary midline on the right side was 3.06 cm, left side 3.07 cm, from infraorbital rim on the right side was 0.94 cm, left side 0.92 cm. Mean length of mental foramen measurement straight to symphysis menti on the right side was 3.19 cm, left side 3.18 cm. Measurement along curvature of the mandible on the right side was 3.49 cm, left side 3.49 cm. Conclusion The knowledge gained from this study is quite important, since it helps the surgeon to easily and practically identify supraorbital notch/foramen, supratrochlea foramen, infraorbital foramen and mental foramen. This will help avoid injury of the neurovascular bundles passing though these sets of foramen.

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.

Object Although craniofacial approaches to the midline skull base have been defined and surgical results have been published, clear descriptions of these complex approaches in a step-wise manner are lacking. The objective of this study is to demonstrate the surgical technique of craniofacial approaches based on Barrow classification (Levels I–III) and to study the microsurgical anatomy pertinent to these complex craniofacial approaches. Methods Ten adult cadaveric heads perfused with colored silicone and 24 dry human skulls were used to study the microsurgical anatomy and to demonstrate craniofacial approaches in a step-wise manner. In addition to cadaveric studies, case illustrations of anterior skull base meningiomas were presented to demonstrate the clinical application of the first 3 (Levels I–III) approaches. Results Cadaveric head dissection was performed in 10 heads using craniofacial approaches. Ethmoid and sphenoid sinuses, cribriform plate, orbit, planum sphenoidale, clivus, sellar, and parasellar regions were shown at Levels I, II, and III. In 24 human dry skulls (48 sides), a supraorbital notch (85.4%) was observed more frequently than the supraorbital foramen (14.6%). The mean distance between the supraorbital foramen notch to the midline was 21.9 mm on the right side and 21.8 mm on the left. By accepting the middle point of the nasofrontal suture as a landmark, the mean distances to the anterior ethmoidal foramen from the middle point of this suture were 32 mm on the right side and 34 mm on the left. The mean distance between the anterior and posterior ethmoidal foramina was 12.3 mm on both sides; the mean distance between the posterior ethmoidal foramen and distal opening of the optic canal was 7.1 mm on the right side and 7.3 mm on the left. Conclusions Barrow classification is a simple and stepwise system to better understand the surgical anatomy and refine the techniques in performing these complex craniofacial approaches. On the other hand, thorough anatomical knowledge of the midline skull base and variations of the neurovascular structures is crucial to perform successful craniofacial approaches.

The study aimed to establish and evaluate anatomoradiological landmarks in trigeminal neuralgia patients using computed tomography (CT) and cone-beam CT. CT images of 40 trigeminal neuralgia (TN) and 40 healthy individuals were retrospectively analyzed and enrolled in the study. The width and length of the foramen rotundum (FR), foramen ovale (FO), foramen supraorbitale, and infraorbitale were measured. The distances between these foramen, between these foramen to the median plane, and between the superior orbital fissure, FO, and FR to clinoid processes were also measured bilaterally. Variations were evaluated according to groups. Significant differences were found for width and length of the foramen ovale, length of the foramen supraorbitale, and infraorbitale between TN and control subjects (p < 0.05). On both sides, FO gets narrower and the length of the infraorbital and supraorbital foramen shortens in the TN group. In most of the control patients, the plane which passes through the infraorbital and supraorbital foramen intersects with impression trigeminale; 70% on the right-side, and 67% in the left-side TN groups. This plane does not intersect with impression trigeminale and deviates in certain degrees. The determination of specific landmarks allows customization to individual patient anatomy and may help the surgeon achieve a more selective effect with a variety of percutaneous procedures in trigeminal neuralgia patients.

Abstract Background: With the aid of implants, Björk identified the two-dimensional mandibular stable structures in cephalogram during facial growth. However, we don't know the three-dimensional stable structures exactly. The purpose of this study was to identify the most stable mandibular landmarks in growing patients using three-dimensional images.Methods: The sample was comprised of two cone-beam computed tomography (CBCT) scans taken about 4.6 years apart in 20 growing patients between the ages of 12.5 (T1) to 17.1 years (T2). After head orientation, landmarks were located on the chin (Pog), internal symphysis (Points C, D and E), and mandibular canals, which included the mental foramina (MF and MFA) and mandibular foramina (MdF). The linear distance change between Point C and these landmarks was measured on each CBCT to test stability through time. The reliability of the suggested stable landmarks was also evaluated. Results: The total distance changes between Point C and points D, E, Pog, MF, and MFA were all less than 1.0 mm from T1 to T2. The reliability measures of these landmarks, which were measured by the Cronbach alpha, were above 0.94 in all three dimensions for each landmark. From T1 to T2, distance changes from Point C to the right and left mandibular foramina were respectively 3.39±3.29 mm and 3.03±2.83 mm. Conclusions: During a growth period that averaged 4.6-years, ranging from 11.2 to 19.8 years, the structures that appeared relatively stable and could be used in mandibular regional superimposition included Pog, landmarks on the inferior part of the internal symphysis, and the mental foramen. The centers of the mandibular foramina, the starting points of the mandibular canal, underwent significant changes in the transverse and sagittal dimensions.

ABSTRACT Objectives Previous studies showed there were variations in the interforamina distance of mental foramen between races. The aim of our study is to determine the interforamina distance of mental foramen among Malaysian populations. Materials and methods A total of 503 orthopantomogram (OPG) radiographs were observed. Interexaminer calibration was estimated using the Kappa-Cohen formula. A sheet of transparent paper was superimposed on the panoramic film and the mental foramen was traced on it by using a fine marker pen. A vertical line marking the midline was drawn passing between the maxillary central incisors, the mandibular central incisors, or the nasal septum by using a ruler. The distance of the mental foramen from the midline was then recorded from both the left and the right side. The data were analyzed using chi-square test. Results According to our inclusion and exclusion criteria, 110 OPGs have been excluded and 393 OPGs were selected. In the Malay population, the most common interforamina distance for a male is between 55 and 60+ mm (n= 73, 54.8%). Also, the most common interforamina distance for a female is 55 to 60+ mm (n = 84, 50%). In the Chinese population, the most common interformina distance for a male is between 55 and 60+ mm (n=60, 66.8%). Similarly, the most common interforamina distance for a female is between 55 and 60+ mm (n= 73, 53.8%). Among the Indian population, the most common interforamina distance for a male falls between 55 and 60+ mm (n= 53, 43.4%) and for a female as well (n=50, 54%). According to the chi-square test, the results show that the study is statistically insignificant since the p-value is >0.05 for both the male and female population. Conclusion There is no relationship between the interforamina distance and the ethnicity. The most common interforamina distance for all the races falls between 55 and 60+ mm.

Background: It is essential that the dentist understand the positional variations of the mental foramen to perform different types of dental procedures. This study was conducted to identify the position of the mental foramen among the Saudi population of Al Hasa. Material and Methods: According to the selection criteria of 200 CBCT images, 101 images were selected. The selected images were categorized into five groups with respect to patient age. Each image was evaluated from both sides of the mandible and then recorded in six classes (position I-VI) according to the horizontal position and three classes in the vertical position. Results: In the Saudi Al Hasa population, Type 4 (at the level of 2nd premolar) was the most common location for mental foramen in the horizontal direction, on the right side (n= 41; 40.6%) and on the left side (n=44; 43.6%). Mental foramen was found in the vertical location, Type 3 (below the apex of 1st and 2nd premolars) was found in the right side (n= 54; 53.5%) and left side (n=56; 55.4%). The position of mental foramen is not constant and changes according to gender and ethnicity. This warrants dentists to evaluate patients individually. Conclusion: Even though the present study was done with a small sample of patients it provides a picture about approximate location of mental foramen among the target group of a population.

Objective- The infraorbital foramen is located on the maxillary bone 1 cm under the infraorbital margin. Infra orbital nerve blocks are done in children for managing the postoperative pain which can occur after cleft lip operation and endoscopic sinus operation. Infraorbital nerve can also be damaged in cases of zygomatic complex fractures which are one of the most common facial injuries. So, this study was undertaken to analyze the anatomical variations by comparing various morphometric measurements of infraorbital foramen in dry skulls of adult South Indian population.Materials and methods- 60 dry skulls of unknown sex were used for the study. Various measurements and distance from various surgical landmarks were measured to evaluate the location of infraorbital foramen on both sides. Statistical Analysis was done for the above measurements mean and standard deviation, median, range, and mode were calculated.Results: The mean distance of infraorbital foramen from piriform aperture, lower end of alveolus of maxilla and infraorbital margin was 18.39, 27.88 and 7.09mm on the right and 17.89, 27.31 and 6.95mm on the left side. The mean vertical and horizontal diameter was 3.78 and 3.50mm on the right side and 3.48 and 3.35mm on the left side. In our study, the most common site of IOF in Indian skulls was found to be in line with the second premolar tooth (59.01%), followed by its position between the first and second premolar tooth (27.87%).Conclusion- These results will be helpful for surgeons while doing maxillofacial surgery and regional block anesthesia.Bangladesh Journal of Medical Science Vol.17(4) 2018 p.562-566

Abstract The canine bossa (not listed in TA) was clearly visible in 80% of cases, less prominent in 12% of cases or even absent in 8% of cases. The most commonly is oval in shape with the long axis oriented vertically or slightly oblique infero-medially. In 60% of cases the two fossae showed approximately equal sizes. For the rest of the 40% of the cases, the left one was larger (24 cases) than the right one. In 12% of cases we found a dehiscent anterior wall of the canine fossa for more than half of its height. The myrtiform fossa (also not mentioned in the TA) was oval, with the long axis oriented vertically and with same dimensions bilaterally in 60% of cases. In 2/3 of cases was evident (deeper) on the right. In 28% of cases we found it rounded, more frequently also on the right and in 12% of cases we found it as having an irregular shape. In about 10% of cases have it was almost flat. The canine fossa (Fossa canina) has various shapes, more frequently rounded with an average diameter of 0.8-0.9 cm. In 30% of cases was oval, with vertical long axis of 1 cm in and 0.7 cm width. The cases of rounded canine fossa, well circumscribed and deeper, were more prevalent on the left. The infraorbital foramen (Foramen infraorbitale) was circular in equal proportions (in half of the cases), with a diameter of 2.5-5 mm, or oval, with 3-5 mm vertical axis and 1.5-3 mm horizontal axis. Note the difference in shape in the same skull: circular on the left and oval on the right (most frequent case) or vice versa. The distance from the infraorbital border is variable, being lower on the left in 65% of cases. Compared to the piriform aperture, the infraorbital foramen is located at 0.9 to 1.7 cm on the right and at 1.2-1.7 cm on the left. We encountered five cases with double infraorbital foramen. The intermaxillary suture is vertical in only 35% of cases. In other cases it is deviated to the left in 40% of cases, and in 25% of the cases is oriented to the right. The degree of inclination is variable, making with the horizontal an angle between 95 to 1100. The alveolar process (Procesus alveolaris) is wider posteriorly. There is a difference in width right-to-left, being wider on the right side in 40% of cases (6-13 mm), are the same size on both sides in 30% of cases, the other 30% of cases being thicker on the left. The zygomatic process (Procesus zygomaticus) may be sharp or, more frequently, with a serrated or rounded edge and with a small tubercle in almost 50% of cases
