Abstract :

Introduction Hiatus semilunaris is a cleft in the middle meatus of nose. Maxillary, Anterior Ethmoidal and Frontal air sinuses open in this cleft. It is essential for otorhinolaryngologists to know the exact position of the Hiatus semilunaris and the exact sites of openings of the paranasal air sinuses during various endoscopic procedures and surgeries.

Materials & Methods In the present study the Length and Height of the Hiatus semilunaris were measured in cadavers by using sliding vernier caliper. Total 50 specimens were studied; in that 27 were of right and 23 of left side. Anterior and posterior distance of Hiatus semilunaris from anterior and posterior nasal openings was also measured and statistically analysed.

Results Average Length of Hiatus semilunaris on Right side is 1.72cms & on the Left side is 1.78cms. Average Breadth of Hiatus semilunaris on Right side is 0.34cms & on the Left side is 0.34cms.

Discussion Parameters are useful for Anatomists as well as for Otorhinologists to know the exact position of the Hiatus semilunaris during various surgeries.
