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

The Pterion is a point of sutural confluence formed by frontal, parietal, temporal and sphenoid bones. Center of pterion is located 4cms above the midpoint of zygomatic arch and 3.5cms behind the fronto-zygomatic suture. Pterion is a reference landmark for many regions of the brain. Knowledge of various types of pterion is important in neurosurgeries as pterion keyhole approach has several advantages over traditional craniotomy; it has got radiological significance in interpretation of radiographs; in forensic medicine, it has been used for estimation of age and stature; and types of pterion has racial variations, hence it has got anthropological significance. Hence, the present study was taken to assess various types of pterion in South Indian adult human skulls. To classify the types of pterion based on Murphy’s classification and compare the right and left sides.The study was conducted on 100 adult dry human skulls collected from Kempegowda Institute of Medical Sciences & Research center, Bangalore. The various types of pterion were noted. All the readings were tabulated and subjected to analysis. All measurements and frequencies of the data were tabulated. The mean, standard deviation for each of the measurements were assessed. Statistical software SPSS version 16 was used. Right and left side were compared using One-Way ANOVA (Analysis of Variance). Various types of pterion were observed. Spheno-parietal was the most predominant (78%) type, followed by epipteric (16%), stellate (4%) and fronto-temporal (2%).: The results of the present study can be utilized by neurosurgeons, radiologists, anthropologists and forensic experts. The findings can be used in future for comparing various types of pterion from a different population, race or species altogether.

Background: The purpose of this paper is to describe an anatomical variation of the hand extensor on the little finger of the right hand which receives four tendons, condition unknown, as it is the first case reported so far in the literature. The human extensor tendons of hand often display an array of variations. Awareness of the anatomy and variations of the extensor tendons on the dorsum of the hand is necessary not only for the anatomist but also for surgeons when considering tendons for hand surgery, tendon rerouting or transplants. Materials and Methods: Bilateral anatomical variation in the upper limb was found during routine dissection in a 75-year-old male cadaver in the Morphology Laboratory at the University of Pamplona. The variations were recorded and photographed. Result: In the left hand the extensor digitorum there was a single tendon to the index, double tendon to the middle, triple tendon to the ring finger, a single tendon to the little finger or digiti minimi. The extensor digiti minimi has double tendon. In the right hand the extensor digitorum there was a single tendon to the index, triple tendon to the middle finger, triple tendons to the ring finger, a double tendon to the little finger. The extensor digiti minimi has double tendon. The little finger receives four tendons, 2 of extensor digitorum and 2 of extensor digiti minimi. The dorsum of the left hand and right showed juncturae tendinum type 2, between the extensors tendons in the 3rd intermetacarpal space; type 3, between the extensors tendons in the 4th inter metacarpal space. Conclusion: The presence of multiple tendons may alter the kinematics around the site of attachment to the phalanx. Knowledge of anatomical variations and normal anatomy of the extensor tendons, may be helpful while performing graft and tendon transfer operations.Bangladesh Journal of Medical Science Vol.15(2) 2016 p.278-282

Objective: The purposes of this study were to evaluate and compare the maxillary sinus volume (MSV) of patients with a unilateral cleft lip and palate (UCLP) between the cleft side and noncleft side and between adolescent patients with UCLP and a control (noncleft) group using cone beam computed tomography (CBCT). Methods: CBCT images of 44 UCLP patients (29 males and 15 females, with a mean [SD] age of 13.5 [5.0] years) and 44 (22 males and 22 females, with a mean [SD] age 14.9 [4.2] years) age- and sex-matched controls were evaluated in this study. Each maxillary sinus was assessed 3-dimensionally, segmented, and its volume was calculated. Results: There were no statistically significant differences between the age and gender distributions of the groups. There was a statistically significant difference in the MSVs of the cleft (10996.78±3522.89 mm3) versus the noncleft side (10382.3±3416.2 mm3; P < .05)] but no significant difference between the MSVs of the right and left sides ( P > .05). In the intergroup comparison, the mean MSVs of the UCLP patients (10701.52±3369.33 mm3) were significantly smaller than those of the control group (16054.08 ± 5293.96 mm3; P < .001). Conclusions: The MSVs of the UCLP patients showed a statistically significant decrease compared to those of the controls ( P < .001). There was also a significant difference in the MSVs of the cleft and noncleft sides of the UCLP patients ( P < .05).

Comprehensive understanding of the anatomy of the inferior palpebral (IP) nerve is crucial to preservation of sensation in the inferior eyelid and conjunctiva. Iatrogenic injuries may occur during blepharoplasty, repair of orbitozygomatic fracture and other maxillofacial surgeries involving this region. Although several studies depict the anatomical variations of the main infraorbital nerve (ION), little information exclusive to the IP nerve exists. This study provides information on the additional variations of the ION with reference to the IP nerve. The study was performed on 84 IP nerves by dissection of 42 formalin-fixed cadavers from the laboratory of topographic anatomy, Department of Human Anatomy, University of Nairobi, Kenya. Each of the nerves were exposed at the emergence and followed to their termination. Variations encountered involved emergence, course, and even absence. Variant emergence was through an accessory infraorbital foramen, an infraorbital notch, and as a common trunk with the external nasal nerve. This nerve shows high anatomical variability that may account for the difficulties and complications encountered in clinical interventions. It is believed that this information will improve clinical management of conditions affecting the region of distribution of the IP nerve.

Sinus Ostium

Rhinosinusitis is one of widely spread diseases in the region and the role of the anatomical variations in its pathogenesis remains unresolved. A retrospective study using CBCT scan was employed to locate and measure the diameter of 320 primary maxillary ostium (PMO) (n = 160 subjects) among the Malay and Chinese populations (Mongoloid race) in Malaysia. Image analysis was performed using the i-CAT Vision Software, employing the multiplanar reconstruction window in which axial, coronal and sagittal planes were visualized in 0.3 mm intervals. The mean diameter of the PMO was significantly larger in the Chinese than the Malay. Females had larger size than the male and bilateral asymmetry was noticed, where the right side PMO was larger than the left side (p < 0.05). In addition, PMO opened more in the posterior third position of the hiatus semilunaris (61.9%) than anterior and middle third. The PMO showed a statistically significant posteriorly placed position in the Chinese than the Malays and this was more evident in the right side PMO (p < 0.01). In conclusion, the PMO commonly opens in the posterior third of the hiatus semilunaris and its diameter is significantly greater in the Chinese female with evidence of bilateral asymmetry. Awareness the anatomical variation of the Ostium diameter and location among the Malay and Chinese populations potentially has important clinical effects during surgical procedures.

Objective: A Cross-sectional descriptive type of study was done in the Department of Anatomy, Dhaka Medical College, Dhaka, from July 2008 to June 2009, to see the variation in the volume of the adrenal glands with age in Bangladeshi people. Materials & Methods: The study was performed on 140 post mortem human adrenal glands collected from 70 unclaimed dead bodies which were in the morgue under examination in the Department of Forensic Medicine, Dhaka Medical College, Dhaka. The samples were divided into four age-groups including group A (11-20 years), group B (21-30 years), group C (31-40 years) & group D (41-60 years). The length, breadth and thickness of each adrenal gland were measured by using a slide calipers. Then the volume of each adrenal gland was determined by the product of its length, breadth and thickness multiplied by 0.52, according to the prolate ellipsoid formula. Results: The mean volume of the right adrenal glands were found 6.36±0.85 cm3 in group A (11-20 years), 6.49±0.76 cm3 in group B (21-30 years), 6.50±0.80 cm3 in group C (31-40 years), 6.76±0.79 cm3 in group D (41-60 years). The mean volume of the left adrenal glands were found 6.97±1.02 cm3 in group A (11-20 years),6.93 ±0.83 cm3 in group B (21-30 years), 6.65±0.79 cm3 in group C (31- 40 years), 7.09±0.81 cm3 in group D (41-60 years). The differences between the right and left adrenal glands and the difference between age groups were not statistically significant.

Regional nerve blocks are necessary to facilitate equine oral surgery in the standing sedated patient. Step-by-step instruction on how to perform common regional nerve blocks are discussed, including infraorbital, maxillary, middle mental, and inferior alveolar nerve blocks. Regional nerve blocks are critical when performing dental procedures in the standing horse.1 The infraorbital and maxillary nerve blocks provide anesthesia of the infraorbital nerve, which is a branch of the maxillary nerve. Both nerve blocks provide adequate anesthesia for all maxillary dental procedures.1 When the infraorbital nerve block is utilized, care must be taken to advance the needle into the infraorbital foramen in order to appropriately anesthetize the caudal maxillary teeth. Mandibular dental procedures require anesthesia of the inferior alveolar nerve, which is a branch of the mandibular nerve. Local anesthesia at the level of the mental foramen will result in anesthesia of ipsilateral incisors and canines, while anesthesia at the level of the mandibular foramen will anesthetize the entire ipsilateral mandibular dental quadrant. All nerve blocks should have the injection site aseptically prepared prior to the procedure. The 4 most common dental nerve blocks are described step by step.

Comprehensive Study

The lower end of humerus has numerous fossae which play a significant role during extreme movements. Coronoid fossa and olecranon fossa are separated by a delicate supratrochlear septum; occasionally septum has perforation and form an aperture, named as Supratrochlear foramen (STF). The knowledge of this foramen will be beneficial for anatomists, anthropologists, orthopedic surgeons, and radiologists. The aim of the present study was to establish the prevalence and morphometry of STF of the humerus in South Indian population and to correlate with the previous studies. The present prospective study was carried out with 274 (146 left sided + 127 right sided) dried humeri of unknown sex and age. The distal humeri were examined for the presence of STF, morphometry such as diverse shapes, vertical and horizontal diameters, and distance from STF to medial, lateral epicondyle and also to the inferior margin of trochlea using digital vernier caliper. In the present study, out of 274 dried humeri, 69 showed presence of STF, 163 were translucent and 42 were opaque. The prevalence of STF was 25.18%. After keen observation, shapes of the STF were categorized accordingly. The oval (42%) showed higher percentage whereas the other shapes showed as follows: - irregular (12%), round (19%), rectangular (12%), reniform (9.7%), sieve (7.3%) and triangular (2%). The mean vertical and transverse diameters of STF on the right side were 3.12 ± 1.09 and 5.5 ± 1.83mm and on the left side, it was 3.47± 1.32 and 4.9± 1.5mm respectively. The mean distance from STF to medial and lateral epicondyle on the right side was 25.12± 3.1 and 28.09± 2.3mm and for the left side 24.97± 2.9mm and 27.16± 2.4mm respectively. The anatomical knowledge regarding the supratrochlear foramen is much promising for the orthopaedic surgeons during intramedullary nailing for supracondylar fracture of humerus. STF appears as a radiolucent area in radiographs, which may pose a difficulty for the radiologist in differentiating it from an osteolytic or cystic lesion. In addition, STF is predominantly found in the primates, it may act an evolutionary link between the humans and lower animals.

Background: Anatomy of circle of Willis (COW) shows extensive variations in different individuals and signifies the causation and presentation of clinical disease. The present study aims to evaluate the different anatomical variations of the Circle of Willis (COW) in general population, using magnetic resonance (MR) 3D-time of flight angiography and to correlate the observations with age and gender characteristics.Methods: This observational clinical study was conducted January 2013 to March 2014 in 503patients who were referred for MRI – Brain. MRI (Philips 1.5 Tesla magnet) with routine brain sequences along with 3D –TOF MRA was done in all patients. The anatomical variants of the anterior and posterior components of the COW were studied. The complete COW was assessed and the diameters of all the components were measured. The correlation between the vessel diameters in relations to age and gender were evaluated.Results: The mean age group of study participants was 42 years. Male dominance was seen among participants (57.1%). The complete configuration of the circle was seen in 31.6% of population. Most common anterior variant is type A (normal anterior configuration) with a prevalence of 52.9% and posterior variant is type K with a prevalence of 32.9%. Average diameters of the proximal vessels supplying the COW were larger in the older age subjects (centripetal vessels, the right and left ICA s and BA). Statistically significant differences between the mean vessel diameters between males and females were seen in the ICA-RT, ICA-LT, and PCOA-LT.Conclusions: The present study showed great variability of the anatomy of the COW in asymptomatic person. Various variants of COW can be picked up by MRA which is safer and non-invasive when compared with CTA / DSA. Knowledge of these variations would help in planning surgical procedures as well as preventing unwanted interventions.

Background: Tendoachilles is the chief plantar flexor of the ankle joint. The present study was conducted to find out the possible variations of tendoachilles between the right and the left leg of both male and female.Materials and methods: A cross sectional observational study was conducted in the department of Anatomy, Dhaka Medical College, Dhaka, from July 2013 to June 2014. The data were collected from both the right and the left tendoachilles of 60 human cadavers taken from Anatomy Departments of different Government and Nongovernment Medical Colleges in Dhaka city. Among the 60 cadavers, 30 were male and 30 were female. After dissection, the length of tendoachilles and the breadths at different levels of tendoachilles were measured and recorded.Results: The mean length of tendoachilles was significantly greater in the right than in the left leg of both male and female. The tendoachilles was longer in male than in female in both the right and the left leg (P<0.01). There was significant positive correlation between the height of cadaver and the length of tendoachilles of both the right leg and the left leg in case of male. Positive correlation was also observed between the height of cadaver and the length of tendoachilles of both the legs in case of female, but that was not statistically significant. The mean breadths of tendoachilles were significantly greater in the right leg than in the left leg at its junction with gastrocnemius and at the level of its junction with calcaneus in both male and female and also in male than in female in both legs. Significant difference was observed between the breadth of right and left tendoachilles at the level of 4 cm above its junction with calcaneus in male but not in female (P>0.05).Conclusion: Significantly greater values were observed in the length and in most of the breadths of tendoachilles in the right leg of both sexes and in male in both legs. There was significant positive correlation between the height of cadaver and the length of tendoachilles of both legs in case of male, but, not in female.Bangladesh Journal of Medical Science Vol.17(3) 2018 p.388-394
