Anatomical variations are not diseases and can be found in every individual. Due to the anatomical variations, the structural changes occur in nearby anatomical relations. By keeping in mind, the vast range of anatomical variations in nasal cavity and paranasal sinuses (PNS), every case of sinusitis must be planned carefully to avoid dreadful complications of surgical procedures. Sinus anatomical variations have been associated with the etiology of sinusitis. In this regard computed tomography (CT) imaging has become an important diagnostic tool. CT Scan imaging of nose and para nasal sinuses is mandatory in patients with history of sinusitis in order to evaluate the detailed anatomy which includes normal anatomy, anatomical variations, bony details and the extent of the disease pathology. Certain anatomical variants are supposed to be a causative factor for development of sinus pathology and hence it becomes compulsory for the radiologist to be aware of the anatomical variants of nasal cavity and PNS especially if the subject is considered for surgical intervention.

(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.
