Abstract


Aims and Objectives: To correlate the anatomical variations of the uncinate process and its relationship with ostiomeatal complex pathologies and
sinusitis on MDCT. The study involved 50 chronic sinusitis patients who underwent CT PNS at M.S. Ramaiah Materials and Methods: aiah Hospitals,
recording demographic details and clinical data. CT images were analyzed using bone and soft tissue window settings to visualize anatomy,
variations, and sinonasal pathology. Results: Among 50 patients of CRS, the majority were aged between 21 to 30 years (28%) with equal gender
distribution. In our study, the UP superior attachment variations were more frequent with type II being the commonest, which was found in 38%,
and type VI being the least common type (4%). 11% had medially bent UP, 1% had laterally bent UP and the UP tip was pneumatized in 6%. Among
other OMC variations, ANC was the most common variation found in 88%. The maxillary sinus was the most commonly involved (60%). In our
study, no signicant correlation was found between the type of UP attachment and frontal sinusitis. However, a signicant correlation between
concha bullosa and maxillary sinusitis was found. Conclusion: The study examined CT images of 50 patients and found that UP superior
attachment variations were more frequent, with Type II attachment to the posteromedial aspect of the ANC being the most common. ANC was the
most common OMC variation, and the maxillary sinus was the most involved.
