Abstract
Background: In the present study an attempt is made to study the morphometric analysis of ear ossicles to compare and evaluate the various morphometric parameters for designing the prosthesis used by Otologist in people of Gujarat.
Aim: To study normal values of stapes this helps in making of stapes prostheses for otologists.
Material and Method: Present study was carried out on 60 stapes in anatomy department at 3 medical colleges namely Shri M.P. Shah Govt. Medical College, Jamnagar, Govt. Medical College, Bhavnagar and P.D.U Medical College, Rajkot. The present study was conducted after approval from the institutional ethics committee.
Results: the mean total height of stapes was 3.33 ± 0.25 mm, ranging from a minimum of 2.86mm to maximum of 3.9mm. The mean length of footplate of stapes was 2.78 ± 0.15 mm, ranging from a minimum of 2.41mm to maximum of 3.11mm. The mean width of footplate of stapes was 1.34 ± 0.13 mm, ranging from a minimum of 1.05 mm to maximum of 1.73 mm.
Conclusion: The results of parameters of the ear ossicles are very helpful in making ear ossicles prosthesis in ossicular chain pathology in Guajarati population. Variation in the dimension of the ear ossicles might be due to racial difference or regional population difference in India. Variation in the dimension of ear ossicles might be due to various types of instruments used for measurement; methods used for measurement of ossicles or inter observer error by other workers.
