“…The developmental origins of the drainage pathways of the frontoethmoidal region can help us understand this complex region. Some authors, referencing Terracol and Ardouin, assert that the origin of FS lies in one of three primordial cell groups: orbital, nasal, or bullar [ 8 – 10 ]. When we apply their developmental model to our findings, the orbital cell group seems to correspond to [UP–LP] (ethmoidal infundibulum), the nasal to [UP–MT], and the bullar to [BLEB–BLMT] (superior semilunar hiatus).…”

Purpose To perform endoscopic sinus surgery safely and effectively, surgeons need to visualize the complex anatomy of the anterior ethmoid and frontal sinus region. Because this anatomy is so variable and individualized, the foundation of understanding lies in identifying, following, and visualizing the drainage pathway patterns and anticipating possible variations. Methods We studied 100 sides (50 cases: 22 male, 28 female, aged 12–86, average age 46.5 years, ± 19.5) using computed tomography (CT) and multiplanar reconstruction (MPR) to identify and classify the drainage pathways leading to the frontal sinus and anterior ethmoidal cells. Results Analysis revealed five patterns of drainage pathways defined by their bony walls: between the uncinate process and the lamina papyracea [UP–LP]; between the uncinate process and the middle turbinate [UP–MT]; between the uncinate process and the accessory uncinate process [UP–UPa]; between the uncinate process and the basal lamella of the ethmoidal bulla [UP–BLEB]; and between the basal lamella of the ethmoidal bulla and the basal lamella of the middle turbinate [BLEB–BLMT]. In most cases, BLEB formed the posterior wall of the drainage pathway of the frontal sinus, indicating BLEB could be one of the most important landmarks for approaching the frontal sinus. Conclusions As endoscopic sinus surgery depends on an understanding of this anatomy, this study may help surgeons to identify and follow the drainage pathways more accurately and safely through the anterior ethmoid to the frontal sinus.

“…Understanding frontal sinus anatomy remains critical to safe and successful frontal surgery in the setting of both inflammatory and skull‐base disease. In an interesting study by Ferrari et al., the group examined a frontal sinus developmental model popularized by Terracol and Ardouin in the 1960s. This model describes frontal sinus anatomy from a developmental perspective based on pneumatization from 1 of 3 groups of primordial cells.…”
