“…These cells were the least observed in our study i.e. about 1.9% Similar results were observed by Liu X et al, [12] and Llyod et al, [28] who reported the prevalence of agger nasi cell as 0.7% and 3% in chronic rhinosinuistis cases whereas in the study by Dua et al, [6] agger nasi cells were found to be present in 20 patients (40%). The prevalence is very less as compared to 98.5% by Bolger [7], 88.5% by Maru [25], 86.7% by Tonai and Baba [32] and 48% by Asruddin [19].…”

“…Uncinate deviation can impair sinus ventilation especially in the anterior ethmoid, frontal recess and infundibulum regions. The deviated uncinate was found in 9.3% of cases which is similar to the findings of the study by Maru et al, [25] but higher than that reported by Bolger et al, [7] 2.5%, Dua et al, [6] 6% and Asruddin et al, [19] 2% Llyod et al, [28] reported the prevalence of about 16% of deviation of the uncinate process in chronic rhino sinusitis cases and even 65 % prevalence of uncinate process deviation was seen in the study by Mamtha et al, [21].…”

“…It is the epiphyseal platform for the development of the facial skeleton [15]. 74.1% of the patients in our study presented with nasal septal deviation [ [6,19]. Stallmann et al, and Mamtha et al, also reported lesser prevalence of 60% and 65% deviated nasal septum in chronic rhino sinusitis cases respectively [20,21].…”

“…Few studies of Indian origin have examined the putative role of anatomical variations of osteomeatal complex such as concha bullosa, septal deviation, uncinate process variations, agger nasi cells, haller cells and paradoxically curved middle turbinate in the development of traditional CRS [6]. We sought herein to examine the prevalence of these osteomeatal complex variations in the CRS cases through the use of computed tomography.…”

“…In our study we found NSD in 95 % cases These findings were not in accordance with the studies of Azila A et al who reported an incidence of NSD in 50 % cases and Dua K et al who reported an incidence of NSD in 44 % cases [5,6]. This high incidence of NSD can be explained on the basis that our study was a prospective study conducted only in symptomatic population while the study of Azila A et al [7,8] was a case control study and the study of Dua K et al included only diagnosed cases of CRS posted for FESS.…”

Chronic rhinosinusitis (CRS) is a major cause of concern worldwide. Nasal septal deviation (NSD) may either cause osteomeatal obstruction or may interfere with proper airflow and potentially predispose to sinusitis. Due to the lack of a universally accepted classification on NSD it has not been established whether NSD influences the development of sinusitis or not. Mladina in 1987 proposed a classification in which he classified NSD into seven different categories. The aims and objectives of this study are to observe the correlation between NSD and CRS and to study the relation of different grades of NSD with sinusitis as per Mladina's classification. Patients above 18 years of age presenting to ENT OPD with complaint of nasal obstruction, nasal discharge and headache were subjected to CT scan (nose and paranasal sinuses) coronal section with contiguous 5 mm thickness slice perpendicular to the hard palate in prone position. Presence of NSD and sinusitis was observed. 120 cases were studied. The mean age was 28.7 ± 9.37 years with age range 18-58 years. There were 92 (76.6 %) males and 28 (23.3 %) females with a M:F ratio of 3:1. Out of 120 cases, 114 (95 %) cases had NSD. Sinusitis was present in 63 (52.5 %) cases on CT scan. Out of 57 (50.0 %) cases with NSD and sinusitis, 13 (11.4 %) cases had sinusitis on the same side of NSD, 14 (12.28 %) cases had sinusitis on the side opposite to NSD and 30 (26.31 %) cases had sinusitis on both sides of NSD. There was no statistically significant relationship between NSD and sinusitis. As per Mladina's classification vertical deviations accounted for majority of patient's septal deviations with 31 (27.1 %) cases of type II NSD and 24 (21.1 %) cases of type I NSD. The maximum number of cases with sinusitis had vertical deviations with type I NSD in 17 (27.0 %) cases and type II NSD in 18 (28.5 %) cases. The present study reveals that there is no correlation between NSD and sinusitis. Vertical deviations type I and type II are more prone to sinusitis as they involve the nasal valve area.
