An imaging checklist for pre-FESS CT: framing a surgically relevant report

Normal Anatomy and Anatomic Variants of the Paranasal Sinuses on Computed Tomography

“…8) comprise the maxillary ostium, the middle meatus, the ethmoidal infundibulum, the bulla ethmoidalis, the uncinate process, and the hiatus semilunaris. 34 Anatomic variants and the implications (Fig. 9):…”

“…Focal small corticated defects in the lamina papyracea are seen in up to 0.5% to 10% of the population and are not clinically significant. 34 Larger defects (congenital, posttraumatic, or postoperative) in the lamina (Fig. 14) need preoperative documentation to avoid inadvertent orbital injury.…”

Morphological concordance between CBCT and MDCT: a paranasal sinus-imaging anatomical study

“…Anatomical landmarks are highly facilitative for surgeons aiming to perform safe endoscopic sinus surgery, but must be clearly defined during the preoperative period [13,18].…”

“…We herein present the first anatomical study evaluating CBCT and MDCT concordance. The main purpose of this study was to assess the radio-anatomical correlation between CBCT and MDCT, based on the recognition of the 26 anatomical landmarks described by Vaid [18]. A secondary objective was to evaluate inter-rater agreement for each method.…”

Paranasal Sinus Anatomy: What the Surgeon Needs to Know

“…The other draining ostiomeatal unit, located posterior in the nasal cavity, is the sphenoethmoidal recess. It drains the posterior ethmoid sinus lateral to the superior turbinate and drains the sphenoid sinus medial to the superior turbinate [6,10].…”
