Morphometric Study Of Inguinal Canal On Cadaver

Background: The inguinal canal is an oblique intermuscular passage lying above the medial half of the inguinalligament. Its size and form vary with age and sex, although it is present in both sexes, it is most well developedin male. The inguinal canal in both sexes has been studied by many workers both in India and in other countries.It is observed that the inguinal hernia and recurrence of hernia after surgery is very common in the kosi regionof Bihar. This observational study may help the surgeons during the operation of inguinal hernia.Materials and Methods: Present study conducted at the department of Anatomy, Katihar medical college andhospital Katihar and Lord Buddha Kosi Medical College, Saharsa during the period of 2010 to 2016. The cadaverprovided for dissection to the student of first professional MBBS, are selected for the study. Cadavers withinjured groin region are not taken for the study. Measurements were done by stainless steel scale and spreadingcalliper during dissection of groin region.Results: Anatomy of inguinal canal, superficial inguinal ring, the deep inguinal ring and the related structureswas studied in details in 50 cadavers in the dissection hall at the time of dissection. During this study I havefound that the average length of inguinal canal in the male was 38.35 mm. The longest diameter of deep inguinalring is 13 mm and smallest diameter is 9 mm. The average measurement of superficial inguinal ring was 12mmalong the base and 24mm from apex to base.Conclusion: At the end of the study I have found a little variation from the established facts related to diameter ofsuperficial inguinal ring, position of deep inguinal ring and direction of fibres of external oblique aponeurosis.
