| description | Introduction: Pyramidalis is classified as a vestigial muscle
which is frequently present. It is muscle of the anterior abdominal
wall. It is thought to tense the linea alba. It has been used as a
surgical landmark, source of muscle stem cells and in various
surgical procedures.
Aim: The aim of this study was to describe the morphometry and
morphology of pyramidalis muscle in an adult Indian population
and its correlation with the clinical significance.
Materials and Methods: A cadaveric study on 25 formalin
fixed cadavers (males-17, females-8) was conducted in context
with prevalence, morphology and morphometry of pyramidalis
muscle. Statistical analysis was done using the Chi-Square test
and student’s t-test using SPSS version 23.
Results: The pyramidalis muscle was present in 92% cases,
usually bilaterally (72%) than unilaterally (20%) and more
frequently in males (94.11%) than in females (87.5%). This
study was conducted in Department of Anatomy, Maulana
Azad Medical College, New Delhi, India from August 2014 to
August 2016. Bilateral asymmetry was reported. The mean
length of the muscle in males and females was 52.21±14.32
and 50.13±13.62mm on the right and 53.97±15.11 and
51.22±13.78mm on the left side. No significant gender
predominance existed on the right and left-sided pyramidalis
lengths. The mean width of the right-sided pyramidalis in males
and females was 18.35±5.15 and 17.05±4.99mm and the
left-sided was 17.8±4.80 and 16.21±4.23mm without gender
dimorphism. The mean thickness of the right-sided pyramidalis
in males and females was 4.91±1.33 and 4.53±1.29mm and
the left-sided 4.33±1.28 and 4.38±1.27mm without gender
differences. The mean pyramidalis-puboumbilical index was
35.15±4.38%, 36.01±4.97% in males and females respectively.
No anatomical variations with regard to origin and insertion
were seen.
Conclusion: This study provides valuable information on
pyramidalis muscle which may help in appropriate understanding
of anatomy, functions and clinical significance of the muscle. |
