Frontal sinus and its outflow tract

Abstract

Introduction: The frontal sinus and its outflow tract attracts special concern for the budding otorhinolaryngologists because of its complex location, variation in anatomy and disease processes altering its pathophysiology.The surgical management is challenging and a surgeon must be well aware of its anatomical variation, radiological finding to anticipate the best surgical outcome. Objectives:-To review the frontal sinus and its drainage pathway with respect to anatomy radiology and different surgical methods. Data Analysis:-The FS presents a variety of anatomical variation and multiple pathological situations can direct multiple surgical approaches to deal with them. FR is the area of “surgical bottleneck” with maximum narrowing endoscopically and beginners must know the boundaries of safe work to have an optimal outcome. Chronic rhinosinusitis, frontoethmoidal mucocele and Osteomas are common disease process affecting frontal sinus and there are vast variant of malignant tumors that can affect the area posing special challenge to surgeon, Conclusion:- Different surgical pathologies affect frontal sinuses and its outflow tract which can be managed successfully if surgeon has good knowledge of its relevent anatomy and by use of appropriate surgical tools and individualized approach.
