Introduction: The variation in any one of the component of Ostiomeatal complex causes improper drainage of these sinuses causing chronic sinusitis. Aim: To find out the association between the superior attachment of Uncinate process and frontal sinusitis. Materials and Methods: The CT paranasal sinuses of patients with frontal sinusitis were interpreted to find the superior attachment of uncinate process. The superior attachment of uncinate process is classified as Type 1-Insertion of Uncisnate process into the lamina papyracea, Type 2- Insertion of Uncinate process into the roof of the ethmoid (the skull base) and Type 3- Insertion of Uncinate process into the middle turbinate. The association between the superior attachment of uncinate process and frontal sinusitis were analyzed by using chi square statistical test. Results: A statistically significant association between Type 1 Uncinate process and frontal sinusitis was found (P=0.0093). Conclusion: The superior attachment of uncinate process which alters the frontal sinus drainage may cause the frontal sinusitis.
