Knowledge of accurate surface anatomy is essential for safe clinical practice. Different views and opinions for clinically important surface markings exist between clinicians. Pericardiocentesis is performed as an emergency procedure in conditions aggravating cardiac tamponade. The approach of pericardiocentesis should be held by the hands of an experienced operator because of the surrounding relations. Nowadays, the introduction of imaging-guided procedures, especially echo-guided procedures, has significantly improved the safety and feasibility of pericardiocentesis and has provided the possibility of choosing the best anatomical approach among the apical, subcostal and parasternal approaches. This case report also emphasizes the importance of instillation of agitated saline as a supplementary technique while performing echo-guided pericardiocentesis in order to reduce the likelihood of cardiac chamber perforations. 折りたたむ

Objectives To analyze the occurrence rate of bifurcated mandibular canal (BMC) by cone beam CT(CBCT) and summarise a new classification for further clinical work and academic communication. Method Randomly collected the CBCT images of 350 adult patients. Firstly, we analysed and summarized the BMCs into four types by the position of bifurcation point in the mandible. Second, we did statistics about occurrence. Then we have measured three kinds of distance of Type I and Type II. At last, we compared the advantages and disadvantages about different classifications. Results Among these 350 patients, we found 110 adult people with BMC which indicated the occurrence rate of BMC was 31.43%. The most common type was Type I, especially Type IB, and the least was Type III. Vertical distance between the apex of the second molar, the third molar and mandibular canal are 4.36±2.51 mm and 2.45±2.23 mm. Distance from the apex of two molars to the bifurcated spot are 15.87±6.82mm and 9.32±5.37mm. And the distance between the apex and retromolar foramen in Type I are 22.19±5.97mm and 15.82±4.68mm. Conclusion Comparing with former typing theory, we summarized a new classification which is simpler and more convenient, which should attach scholars’ attention to BMC during clinical work. 折りたたむ

Introduction The foramen ovale is located in the area where intracranial and extracranial structures meet. Procedures involving trigeminal neuralgia and mandibular nerve anaesthesia require an understanding of the foramen ovale's morphometry and anatomy. Our present study was conducted to define mean values and anatomical variations in foramen ovale. Aims 1. To establish the mean length, breadth and the Area of the foramen ovale. 2. And also to study different shapes and special features of the foramen ovale. 3. To compare the values of the present author with the previous studies. Methodology The study was carried out on100 foramen ovale using 50 dry adult human skull bones of unknown sex. Maximum transverse diameter, antero-posterior diameters of the foramen were measured with the help of vernier calipers. and the different shapes of foramen were noted. The data was analysed by using unpaired T test. Results The mean anteroposterior diameter on left side was 6.59±1.37 mm and on right side was 6.99±1.44 mm. The mean transverse diameter on the left is 4.09±0.74 mm and 4.17±0.76 mm on the right side. Incidences of various shapes of the foramen ovale were oval 70%, almond 11%, round 9%, elongated 6%, pear shaped 2 % and irregular 2%. Conclusions The findings from the current study may be useful for understanding the variations of these foramina for interventions in middle cranial fossa. 折りたたむ
