EXTERNAL EAR;

A MORPHOMETRIC STUDY AMONGST STUDENTS OF NAWAZ SHARIF MEDICAL COLLEGE GUJRAT

Abstract

Objectives: To determine morphometric measurements of external ear among
medical students of Nawaz Sharif Medical College, University of Gujrat. Study Design: Cross
sectional. Setting: This study was done among students of First & Second year MBBS classes
at Nawaz sharif Medical College, University of Gujrat. Period: 2015. Methodology: The study
group consisted of 120 girls and 80 boys with age range 18 to 22 (median 20). Total Ear height,
lobular height, lobular width and distances of helical root and insertion of the lobule from the
lateral palpebral commissure were measured by using vernier caliper. Results: With analysis
of normative cross-sectional data, this study endeavors to show anatomic and aesthetic
differences between boys and girls. The average total ear height across the study group for
both left and right ears was 6.50cm. The average lobular height was 1.9cm. The average lobular
width was 2cm. The height of the pinna was significantly larger in boys than girls. The distance
between helical root and lateral palpebral commissure was significantly larger among boys as
compared to girls. The average height and width of the lobule of boys and girls were statistically
insignificant.
