Abstract
ABSTRACT
Background
Precise knowledge of anatomic variations of nose and paranasal sinus complex
is essential for achieving best surgical results during endoscopic sinus surgery.
Computed tomography is the gold standard investigation for evaluation of paranasal
sinuses and adjacent structures.
Objective
To study prevalence of anatomical variations of nose, paranasal sinuses and
osteomeatal complex and to identify a probable association between anatomical
variations and chronic rhinosinusitis.
Method
Prospective, analytical study conducted in 218 patients with Chronic rhinosinusitis
in Department of Radiology, Dhulikhel Hospital, Kathmandu University Hospital
between January 2015 to January 2016. Volumetric axial CT scan was done in 128
slice CT scanner in 3mm thickness from frontal sinus to floor of maxillary sinus with
thin multiplanar reconstruction. Radiological findings were reviewed and obtained
data analyzed with SPSS version 16. Pearson chi square test and Pearson correlation
coefficient were used for statistical analysis.
Result
The most common anatomical variation was pneumatized agger nasi cells followed by
concha bullosa and deviated nasal septum respectively. Statistical significance were
seen between ipsilateral agger nasi cell and frontal sinusitis (p< 0.001), ipsilateral
haller cell and concha bullosa with maxillary sinusitis (p<0.001) and onodi cell with
sphenoid sinusitis (p<0.001), However, no obvious statistical correlation was noted
between deviated nasal septum with ipsilateral maxillary sinusitis.
Conclusion
Precise knowledge of anatomic variations of the paranasal sinuses is important in
chronic rhinosinusitis to prevent possible complications during surgery. Computed
tomography is the modality of choice in evaluation of paranasal sinuses and adjacent
structures.
