Abstract:

Background: Frontal air sinus opens in Hiatus semilunaris of  middle meatus of  Nasal cavity. Nowadays plenty of endoscopic surgeries are happening at Middle meatus; so there is need to explore more about detail anatomy of opening of sinuses. So Present study was undertaken to note the exact site of opening of Frontal air sinus in Hiatus semilunaris of  Nasal cavity.

Context and Purpose of study: Study was conducted on 50 specimens. Out of  that 27 were from Right side & 23 were from Left side. The specimens were the sagittal sections of adult  cadavers  in  the department of Anatomy,Krishna Institute of Medical sciences University, Karad. The parameters measured  were, Distance of Frontal air sinus opening from Anterior end of Hiatus semilunaris (nasal bone). Distance of Frontal air sinus opening from Posterior end of Hiatus semilunaris(Inferior surface of Body of Spenoid bone). Diameter of Frontal air sinus opening. Shape of Frontal air sinus opening. All these measurements were taken by Sliding Vernier Caliper of 30cm length & 0.001 accuracy.

Results:  The mean Distance of Frontal air sinus opening from Anterior end of Hiatus semilunaris (nasal bone) was- 1.63cms  on Left side & 1.52cms on Right side. The mean Distance of Frontal air sinus opening from Posterior end of Hiatus semilunaris(Inferior surface of Body of Spenoid bone) was- 4.26 cms on Left side &  4.17cms on Right side. The mean Diameter of Frontal air sinus opening – 0.19cms  on Left side & 0.18cms  on Right side. The shape of Frontal sinus opening is mainly Circular.

Conclusion and Summary: Knowledge of the anatomy of the Frontal air sinus opening is basically helpful for the Anatomists, to know  where exactly is the site of the opening of Frontal air sinus in the middle meatus of nasal cavity;  And secondarily it might be helpful to ENT surgeons during the performance of  endonasal cystorhinostomies.

Key words: Frontal air sinus, Middle meatus of Nose, Hiatus semilunaris, Nasal cavity, Frontal air sinus opening.
