Anatomical variations in superior attachment of uncinate process and localization of frontal sinus outflow tract

Abstract: <p class="abstract"><strong>Background:</strong> Uncinate process (UP) is a part of ethmoid bone, which is a thin sickle shaped projection on the lateral wall of nose. UP extends from the frontal recess superiorly and inferiorly to the ethmoid process of inferior turbinate. Various studies have shown that superior attachment of uncinate process (SAUP) is the key to frontal recess region in endoscopic sinus surgeries (ESS). But these studies have yielded conflicting results, showing multiple p… Show more

(1) Object: Our study aims to identify the common and diverging points in the superior attachment of the nasal uncinate process (SAUP) classifications and to draw attention to the pitfalls in these evaluation processes. (2) Material and Methods: This study was performed on 200 patients (males/females, 100/100; mean age/range: 37.13 ± 16.14/16–84), and 400 sides were bilaterally evaluated. Potential pitfalls were investigated. All UPs were classified according to the Landsberg and Friedman (LF) and Stammberger and Hawke (SH) classifications, and these two classifications were compared. (3) Results: There was a high statistically significant correlation between SH and LF. SH Type IV and LF Type 0 and SH Type III and LF Type 6 completely overlapped. SH Type I corresponded to LF Types 2 and 3 and SH Type II to LF Type 2, 3, 4, and 5 groups. There was no significant difference between genders or sides (right and left) in terms of the LF or SH classifications. (4): Conclusions: Following the thick band and paying attention to concavity and convexity helps to accurately evaluate the anatomical structure. Only two groups overlapped one to one. For SH Types II and III, and LF Types 1, 2, 3, 4, and 5, knowing the SAUP group in one classification does not give an exact idea about the group of the other classification. Therefore, it is not possible to make comparisons between reports or studies using different classifications.

Objective: The microanatomy of the fronto-ethmoidal transition region has been addressed in several classifications. CT stereoscopic imaging (3DCTSI) provides improved display and delineates three defined complex “spaces”, the Frontal Sinus/Frontal Recess Space, the Infundibular Space of the Ethmoid Uncinate Process, and the Ethmoid Bulla Space (FSRS, IS-EUP, EB), none of which were adequately described with the “cell” terminology. We present details on the 3D microanatomy, variability, and prevalence of these spaces. Methods: 3D stereoscopic imaging displays (3DCTSI) were created from 200 datasets. The images were analyzed and categorized by a radiologist (SJZ), and consultant otolaryngologists, focusing on 3D microanatomy of the fronto-ethmoidal transition, the frontal recess/frontal sinus, and drainage pathways, in comparison to established anatomical classification systems. Results: The anterior ethmoid is subdivided into seven groups with the following core properties and prevalence: 1. The horizontal roof of the IS-EUP is attached to the superior half of the frontal process of the maxilla (19%); 2. The IS-EUP extends into the frontal recess (6.5%); 3. The IS-EUP extends into the frontal recess and the frontal sinus (18.5%); 4. A bulla is seen in the medial frontal sinus (3%); 5. The ethmoid bulla and supra bullar space extend into the frontal sinus (7%); 6. Lamellae extend into the FSRS antero-superiorly (25%); 7. FSRS expansion expands below the upper half of the frontal process of the maxilla (FSRS) (21%). Conclusion: 3-D analysis of the detailed anatomy provides important new anatomic information with the increased focus on precision surgery in the region.

Objective: Our objective is to provide observations demonstrated with 3Dimensional Computed x-ray Stereoscopic Imaging (3DCTSI) in the evaluation of the anterior ethmoid and frontal sinus development from birth to age 18. Methods: This is a retrospective evaluation of patient’s CT studies performed over a fifteen-year period, reported as normal studies, and included 53 patients (142 sides) from birth to age 18. Results: At birth, there are two spaces covered by folds, the uncinate and bulla lamellae. The spaces communicate with the Middle Meatus (MM) through the emerging ethmoid infundibulum (EI) and the retrobulbar recess space (RBRS). In the first month after birth, an expansile and breakdown developmental phase blend and continue throughout the growth into the teenage years. The 3D images reveal dark lamellar structures, on the surface of the medial lamina papyracea as well as bridging the broken spatial outlines. The dark lamellae represent the mucosal lamina propria, in unossified lamellae and are the origin of permanent spatial walls. From ages 4 to 18 years, initially, the frontal recess (FR) and later the MM penetrate into the cancellous frontal bone creating the frontal Sinus (FS), the frontal septum (FS), Inter-Frontal Sinus Septal Cell (IFSSC), as well as the Fronto-Ethmoidal and Frontal Bulla Spaces. Conclusion: 3DCTSI is the first intuitive imaging modality to reveal the microanatomical development of the anterior ethmoid and frontal sinus anatomy.
