This cadaveric study aims to provide a detailed overview of the key steps involved in the dissection of the frontal sinus, including the identification of anatomical landmarks, performing of Draf I, II-A, II-B, and III procedures, and the preservation of mucosal structures. The meticulous identification and preservation of crucial anatomical landmarks, such as the frontal sinus outflow tract, the agger nasi, and the vertical lamella of the middle turbinate, are essential for avoiding complications, including injury to the AEA or inadvertent penetration of the cribriform plate.

By familiarizing themselves with the step-by-step approach outlined in this text and the accompanying video, surgeons can enhance their technical proficiency and improve patient outcomes in the management of frontal sinus-related conditions. For medical students and trainees, this video offers an invaluable learning opportunity to develop a deep understanding of frontal sinus anatomy and the nuances of endoscopic dissection techniques. By using this knowledge, healthcare professionals can enhance their surgical skills, improve patient care, and contribute to the advancement of the field of endoscopic sinus surgery.
