“…Başak et al [30] called the situation of the intersinus septum ending on ICA as dangerous sphenoid septum; and it was reported as the rate of 8 % in adult group [30]. AlAbri et al [31] have determined that intersinus septum end on karotid or optic canal in 3/435 patients (0.6 %).…”

In the present study, we investigated whether there is a relationship between sphenoid sinus (SS) types, septation (lobulation) and symmetry; and septal deviation (SD) by multidetector computed tomography (MDCT). Paranasal MDCT images of 202 subjects (131 males, 71 females), between 10- and 88-year-old, were included into the study. SS type (conchal, presellar or sellar), SS symmetry, SS septation (lobulation) and SD were evaluated by MDCT images. In the present study, in both males (83.2 %) and females (85.9 %); and in all age groups (80.4-85.7 %), sellar type sphenoid sinus were more detected. Conchal type was detected in two cases of the males (1.5 %) and none of the females. SS was detected mainly as multi-septated (multi-lobulated) (51.9 % in males and 56.3 % in females; in all age groups as 51.0-56.8 %; and both SD (+) and SD (-) groups as 51.2-56.8 %). In subjects with SD, asymmetric SS was detected in 80.2 %. Whereas in SD (-) subjects, asymmetric SS was detected in 50.6 %. Sellar type SS pneumatization is the most detected type in our cases. Presence of SD was related to the higher SS asymmetry values. In SD (-) subjects, SS was detected as symmetric. Nasal septal deformities such as SD may influence the development of the SS pneumatization and asymmetric septation. For well anatomic orientation of the surgeons, good anatomy knowledge and preoperative detailed examination of the CT scans are very important.

“…1,2 The main functions of paranasal sinuses include lightening of skull, air humidification and voice resonance. [3][4][5] There are various imaging modalities available for the evaluation of the paranasal sinuses. Conventional radiography has limited role in the evaluation of nasal cavity, ethmoid and sphenoid sinuses because osteomeatal complexes are not delineated by conventional radiography.…”

To investigate the prevalence of anatomic variants of the sinonasal cavities using 128-slice-Multidetector CT and to determine their relation to sinonasal mucosal disease. Material and methods: A total of 200 patients were included. The inclusion criteria were patients with clinical symptoms of chronic rhinosinusitis and e exclusion criteria were patients with history of trauma, sinus surgery and sinonasal tumours and patients with contraindications for CT like pregnancy. All the patients with symptoms of chronic rhinosinusitis underwent CT on a 128-MDCT with field of view of 16cm from roof of frontal sinus till floor of maxillary sinus with reconstruction of 0.625mm. The study was acquired in axial plane and coronal, sagittal reconstructions were made.The CT scans was evaluated for the presence of anatomic variants of the sinonasal cavities and associated sinusitis. Results: The paranasal sinus anatomical variants are highly variable as proved by various previous studies. In our study the most common anatomical variant was deviated nasal septum, followed by agger nasi and concha bullosa. There was no statistically significant correlation between any of these anatomical variants and chronic rhinosinusitis in our study. Conclusion: The paranasal sinus anatomical variants are highly variable. In our study, the most commonest anatomical variant was deviated nasal septum, followed by agger nasi and concha bullosa. There was no statistically significant correlation between any of these anatomical variants and chronic rhinosinusitis in our study.

“…Anatomical disparities of nose have been reported to predispose to sinusitis. 1 Chronic rhinosinusitis is one of the most common illnesses, and it has been known to negatively impact health-related quality of life 2 currently, computed tomography (CT) in both coronal and axial planes is the investigation of choice. Of these, more onuses is on the coronal plane is the most common method used by surgeons because of its similarity with the surgical orientation.…”

Introduction: The anatomy of organs of ENT is a herculean task to understand and evaluate in the whole human anatomy. Knowledge about the possible variabilities is never complete, since there is always a scope to understand better and know more. Many studies have been undertaken in the past to understand better the already existing knowledge about the various anatomical details in the nose and paranasal sinuses causing chronic rhinosinusitis. The present study was carried to know the details of variations in anatomy of nose and paranasal sinuses causing chronic sinusitis. Material and Methods: A Cross sectional study conducted over a period of two years, in patients presenting to ENT OPD with symptoms and signs and chronic rhinosinusitis, in a setting of tertiary hospital, with the requisite investigative protocols. Patients meeting the inclusion criteria were included in the study and subjected to the prescribed interventions. Results: Observations gathered from this study are-of the 65patients included, 86.1% had septal deformities, 58.4% had Concha bullosa, 52.3% had Agger Nasi, 15.3% had Haller Cell, 13% had Paradoxical Middle Turbinate, 4.6% had Everted Uncinate Process, 3% had Enlarged Bulla. Conclusion: Sinonasal anatomy is different in each individual, with various combined variations also.
