title: Variation of Length of Trachea in Different Age & Sex Group of Bangladeshi Cadaver.
abstract: A cross sectional descriptive study was performed on 70 post mortem human trachea (44 of male and 35 of female) to find out the difference in length of the trachea of Bangladeshi people in relation to age and sex. The specimens were collected from the morgue in the department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh by purposive sampling technique. All specimens were grouped into three categories, Group A (upto 20 years), Group B (21-40 years) and Group C (41-60 years) according to age. Dissection was performed according to standard autopsy techniques. The length of the trachea was measured with the help of a metallic tape and data was analyzed by using one way ANOVA test. A general trend of increasing tracheal length was observed as age advanced. The mean±SD length of the trachea was 7.88±1.01cm in Group A, 8.81±0.81cm in Group B and 8.94±1.04cm in Group C. The mean length of the trachea in male were 8.1±0.81cm, 8.95±0.69cm and 8.92±1.1cm in Group A, Group B and in Group C respectively and in female the length were 7.57±1.24cm, 8.61±0.96cm and 9±1cm in Group A, Group B and Group C respectively. Variance analysis shows significant difference in mean length of the trachea between the age Group A & B and Group A & C but no significant difference was shown between Group B & C. No significant difference of length of trachea between male and female was observed. The study would help to increase the information pool on the length of the trachea of Bangladeshi people.
