*Address for Correspondence: Dr. Pratishtha Potdar, Associate Professor, Department of Anatomy, Santosh Medical College, Ghaziabad, India E-mail: drpratishthagupta@gmail.com  Received: 11 Apr 2019/ Revised: 09 Jul 2019/ Accepted: 27 Aug 2019 ABSTRACT Background: Morphometric dimensions of ear plays a very important role in plastic surgery and prosthetics. This study aimed to determine different morphometric parameters of both ear and to provide information regarding age related changes. Methods: A study was conducted on 167 subjects including both males and females. The ear was measured using vernier caliper with an accuracy of 0.001 and recorded in millimeters (mm) in a data sheet. The size of pinna and the lobule were measured on both right and left side and were correlated with age of the individual. Readings were statistically analyzed in order to determine the relationship between the size of the pinna and the age of the individual. Results: In our study of age 18–30 ear length was 6.15 cm, lobule length and width was 1.87 cm and 1.99 cm and in age 31–40 ear length was 6.32 mm, lobular length and width was 1.95 cm and 2.01 cm and in age 41–50 yrs ear length was 6.415 cm, lobular length and width was 1.98 cm and 2.06 cm. This shows that in our study ear length were increasing significantly with age and similarly Rt and Lt lobular length and Lt lobular width were also increasing significantly with the age. There was no significant difference between the size of the right and left pinna. Conclusion: The present study shows that the expansion of auricle with age was related to structural change in auricular cartilage. The ear morphometry also helps in predicting ear anomalies and to reproduce anatomically corrected ear during its reconstruction.
