A Study of the relationship of structures at Mandibular Foramen
(Institute of Medicine, 2014) Baral, P; Bastola, D; Shrestha, RN
Abstract Introduction: Mandibular foramen is located on medial aspect of ramus of mandible. Inferior alveolar artery and nerve enters into the foramen and inferior alveolar vein comes out of it. Dissection studies on 16 male and 4 female cadavers suggested that inferior alveolar nerve was medial to inferior alveolar vessels and inferior alveolar artery was anterior to inferior alveolar vein. Knowledge of interrelationship of structures at mandibular foramen is important for dental surgeon or oral surgeons while giving the inferior alveolar nerve block. Keywords: mandibular foramen, inferior alveolar nerve, inferior alveolar artery
Calvarial Thickness of the Nepalese Dry Skulls
(Institute of Medicine, 2015) Baral, P; Koirala, S; Bajracharya, S; Jha, CB; Banstola, D; Shrestha, RN
Abstract Introduction: Calvarium of skull comprises frontal,parietal and occipital bone.These bones cap over the brain in cranial cavity. These bones are flat bones having outer and inner tables made up of compact bone. There is cancellous bone called as diploe in between the outer and inner table. The aim was to measure the thickness of calvaria at various points on Nepalese skull and establish Nepalese database of calvarial thickness and also to compare thickness on the right and left side for bilateral points. Methods: Around140 calvaria of dried skull were studied. Thickness of various points on the frontal, parietal and occipital bones that form calvaria were measured with spreading caliper. The inner table, diploe and outer table thickness were measured with vernier caliper. Results: The mean thickness of frontal bone is 5.6 ± 0.8 mm;out of which the outer table 1±0.2mm, the inner table 0.8±0.3mm and the diploe 3.8±0.6mm.The mean thickness of parietal bone is 4.5±0.6 mm; out of which the outer table 0.8±0.2mm, the inner table 0.6±0.2mm and the diploe 3.1±0.4mm. The mean thickness of occipital bone is 8.5±0.7 mm;out of which the outer table 2.2±0.4mm, the inner table 1±0.3mm and the diploe 5.7±0.6mm.There is significant difference in the mean thickness of the frontal, parietal and occipital bone(p<0.05). Theoverallmean thickness of the calvarium is 6.5±0.7 mm;out of which the outer table 1.5±0.3mm, the inner table 0.8±0.2mm and the diploe 4.5±0.5mm.The outer table is significantly thicker than the inner table(p<0.05). Conclusion: All these results indicate that the calvarium is not uniform in thickness and there is increased thickness towards the posterior and the outer table is thicker than the inner table. Keywords: calvarium, outer table, diploe, inner table
Can homemade alcohol (raksi) be useful for preserving dead bodies? An experiment on wistar albino rats
(Kathmandu University, 2007) Dhungel, S; Maskey, D; Jha, CB; Bhattacharya, S; Paudel, BH; Shrestha, RN
Introduction: Embalming is the through disinfection and art of preserving bodies after death using chemical substances. It keeps a body life like in appearance during the time it lies in a state prior to funeral. Objective: This study was undertaken to investigate the effectiveness of Raksi in sacrificed rats in arresting postmortem changes and establishing scientific fact whether Raksi can be an alternative to standard embalming constituent if it is not available. Material and methods: 50 albino rats were systematically randomized into control and experiment groups. Raksi and distilled water were injected for embalming purpose intraventricularly in experiment and control groups of rats respectively and kept for 48 to 96 hours for observation for postmortem changes. Result: Observations made at 48 and 72 hours of embalming revealed that Raksi can arrest postmortem changes in the rats up to 72 hours (3 rd day) successfully in the experimental group whereas moderate to severe postmortem changes were seen in the control group. The experimental group showed mild degree of putrefactive changes, liberation of gases and liquefaction of tissues only at 96 hours (4th day) of embalming. Discussion: The Raksi used in this experiment contained 34% of alcohol, which was determined by an alcohol hydrometer. Experiment clearly demonstrated from its result that raksi can be utilised temporarily for embalming since it contains alcohol and has preservative, bactericidal and disinfectant properties. Conclusion: It is concluded from the study that this knowledge if applied to dead human subjects, may preserve dead bodies temporarily allowing delayed funeral.

Morphometric study of trachea in adult cadavers
(Institute of Medicine, 2018) Bhandari, R; Ranjit, N; Shrestha, R; Shrestha, A; Adhikari, B; Shrestha, RN
Abstract Introduction: Knowledge of tracheal morphometry is essential for carrying out interventional procedures of the airway like endotracheal intubation, tracheostomy and tracheal stenting. It has been described that the length of human trachea ranges from 10 to 11 cm and the internal tracheal diameter in transverse axis is about 12 mm in adults. The main objective of this study is to evaluate the tracheal length and its internal and external diameters from adult Nepalese cadavers. Methods: A total number of 182 cadavers, 132 male and 50 female, with Nepalese nationality were studied. The study subjects were 18 years or above. Tracheal length, internal and external tracheal diameters in anteroposterior and transverse axes were measured after photographic record of the sample. Result: The mean tracheal length was 82.87±8.3 mm in male and77.59±9.3 mm in female. The TEDAP were 18.95±2.0 mm and 15.83±2.2 mm in male and female respectively. The TEDTR were 23.73±3.5 mm and 20.70±3.0 mm in males and females respectively. The TIDAP in males was 9.34±2.2 mm and in females was 6.88±1.7 mm. The TIDTR was 13.24±2.9 mm in males and 10.51±2.9 mm in females. Conclusion: The tracheal dimensions of our study showed marked dissimilarity with those of the studies conducted in western population. Keywords: endotracheal intubation, tracheal diameter, tracheal length
Supernumerary head of biceps brachii: A rare occurrence in the Nepalese population
(Kathmandu University, 2008) Vijayabhaskar, P; Baral, P; Vaishya, R; Shrestha, RN
Abstract Unilateral three headed biceps brachii muscle was observed in the dissected cadaver of a 45-year-old Nepalese cadaver. The supernumerary head is taking origin from the tendon of deltoid and crossing in front of the long head of biceps and joining with short head of biceps brachii. The incidence of this variation is very rare and there was no available literature in Nepalese population. Presence of such variation should be kept in mind by Surgeons and Traumatologists. Key words: Biceps brachii muscle, Supernumerary head
