Which sinus is located in the forehead region?

The frontal sinus is located in the forehead region, situated behind the brow ridges within the frontal bone of the skull. This sinus plays a significant role in the drainage and mucosal function of the nasal cavity, contributing to the overall respiratory system. Its location makes it particularly relevant during assessments for sinusitis and other upper respiratory conditions, as symptoms like pain or pressure are often felt in the forehead area when the frontal sinus is involved. Understanding the anatomical position of the frontal sinus aids in diagnosing issues related to sinus infections or blockages, reinforcing the importance of accurate localization in HEENT assessments.
