“…Furthermore, the wide range of numbers and types of the studied CT scans in different studies may also potentiate this discrepancy. For example, maxillary growth is highly affected by environmental factors such as abnormalities in the growth of paranasal bone, trauma, adenoid hypertrophy and nasal septum deviation [ 37 , 38 ].…”

Concha bullosa (CB) is a pneumatic cavitation inside a concha in the nasal cavity. It is one of the most widely recognized nasal variations and is mostly found in the middle concha. CB is divided according to its site into three types; lamellar, bulbous and extensive. The goal of our study was to estimate the prevalence of CB among Saudi adult population and its association with sinusitis by using multidetector computed tomography (MDCT). This was a retrospective study carried out over a three-year period on 879 adult Saudi patients aged 18 years or older, referred for MDCT assessment of paranasal sinuses. Males were 540 and females were 339. Patients with facial congenital anomalies or nasal trauma were excluded from our study. CB was prevalent in both males and females among Saudi population (55.4%, 55.7%) respectively. Bilateral CB (55.5%) was more frequent than unilateral (44.5%). Extensive CB (44.0%) was the most frequent type. Sinusitis was associated more in patients with CB (48.0%) versus those who have no CB (5.9%). In conclusion, CB was prevalent among Saudi population and the most frequently recorded is the extensive type. Furthermore, the most common type associated with sinusitis was extensive CB (49.6%).

Introduction:Evaluation of the olfactory fossa (OF) before endoscopic sinus surgery is important in minimizing inadvertent penetration into the anterior cranial fossa. This study assessed the depth of the OF using computed tomography (CT) images of adult Nigerians.Materials and Methods:Cranial CT images were obtained from the database of the radiological unit of a referral center in Delta State, Nigeria, after ethical clearance. The images belonged to 137 female and 199 male adults aged ≥20 years. The depth of OF was measured as the perpendicular distance between the cribriform plate (CP) inferiorly to the superior end of the lateral lamella of the CP on coronal sections. The fossae were classified as Keros Type I (0.1–0.39 cm), Type II (0.4–0.79 cm), and Type III (>0.8 cm). Data collected were analyzed using the Statistical Package for the Social Sciences version 23. Side and gender comparisons of the depth were evaluated using the Student'st-test, while the variations in the OF types were assessed using the Chi-square test. These comparisons were regarded significant whenP< 0.05.Results:The mean OF depth was larger in males (0.543 ± 0.183 cm) than in females (0.527 ± 0.169 cm) (P= 0.018). The prevalence of symmetrical (64.9%) and asymmetrical (35.1%) OF showed significant sex differences (P< 0.05). Type II OF was the most common (77.2%), followed by Type I (15.8%) and Type III (7%).Conclusion:The presence of the deep (Type III) and asymmetric OF in the patients studied emphasizes the importance of their preoperative radiological identification to minimize complications.
