Abstract :

INTRODUCTION : The tympanic cavity contains three small immovable bones, the malleus, incus and stapes which have a fundamental role in transmission of sound. Sclerosis, ankylosis or any disease of these ossicles cause immobilization and dislocation of the chain leading to impaired he�. The Incus plays an important role in conveying viations of tympanic memane form Malleus to Stapes. Study was conducted to determine various morphometrical parameters of Incus which can be helpful during reconstructive procedures to the Otologic surgen for the improvement of sound conduction. MATERIAL AND METHOD : The prospective study was performed on 114 subjects (61 males and 53 females) in Dr. D.Y. Patil, Hospital navi, Mumbai, CT scan images of 114 subjects are studied for ossicular chain on either side, and the Incus are obtain to investigate the morphometric parameters. RESULT : The average of Morphometric parameters shows that the mean Total length of right Incus is 5.31 mm in male and 5.26 mm in female, where the mean Total length of left side Incus is 5.41 mm in male and 5.27 mm in female. The mean Total width of Right Incus is 4.29 mm in male and 4.28 mm in female, where the mean Total width of left Incus is 4.38 mm in male and 4.24 mm in female. The mean Length of long process of right Incus is 3.18 mm in male and 3.36 mm in female, where the mean Length of long process of right Incus is 3.22 mm in male and 3.42 mm in female. No significance difference was found when we compared these parameters of right and left side in both sexes. CONCLUSION : The knowledge of the morphometry of Incus will helpful in designing of implants during operations to improve he�.
