摘要：Background: Frontal air sinus opens in Hiatus semilunaris of middle meatus of Nasal cavity. Nowadays plentyof endoscopic surgeries are happening at Middle meatus; so there is need to explore more about detail anatomyof opening of sinuses. So Present study was undertaken to note the exact site of opening of Frontal air sinus inHiatus semilunaris of Nasal cavity.Context and Purpose of study: Study was conducted on 50 specimens. Out of that 27 were from Right side & 23were from Left side. The specimens were the sagittal sections of adult cadavers in the department ofAnatomy,Krishna Institute of Medical sciences University, Karad. The parameters measured were, Distance ofFrontal air sinus opening from Anterior end of Hiatus semilunaris (nasal bone). Distance of Frontal air sinusopening from Posterior end of Hiatus semilunaris(Inferior surface of Body of Spenoid bone). Diameter of Frontalair sinus opening. Shape of Frontal air sinus opening. All these measurements were taken by Sliding VernierCaliper 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 fromPosterior 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 Rightside. 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 theAnatomists, to know where exactly is the site of the opening of Frontal air sinus in the middle meatus of nasalcavity; And secondarily it might be helpful to ENT surgeons during the performance of endonasalcystorhinostomies.
