Background: Paranasal sinuses are a group of four paired air filled spaces surrounding the nasal cavity. During the developmental process, anatomical variations can occur in consequence of intra and extramural migration of the ethmoidal air cells, over pneumatization or hypoplasia of the sinuses and bulging of the neurovascular structures to the sinuses, thereby affecting the drainage pathways, causing chronic infections and complications during functional endoscopic sinus surgery (FESS). The aim of the study was to study the clinical significance of paranasal sinuses and it’s anatomical variations using CBCT.Methods: A retrospective study was carried out at Meenakshi Ammal Dental College, Chennai, from June 2018 to November 2018 using 100 CBCT images of 50 males and 50 females, with their age group ranging from18-60 years. Radiographic assessment of paranasal sinuses and it’s variations were accurately characterized using customized Planmeca Romexis software and the data was analysed statistically. Results: It is found that agar nasi cells were found to be higher 79% followed by Kuhn cells 45%, onodi cells 23% and haller cells 12%. Concha bullosa was found in 39%. Nasal septum was deviated to right in 31% and to the left in 36%. Maxillary sinus septa in 21%, sphenoid sinus pneumatization in 23%,maxillary sinus pneumatization in 2%, and crista galli pneumatization in 7% of the study population. And the results based on gender, the p value is found to be highly significant.Conclusions: CBCT is the best tool for imaging the paranasal sinuses including osteo meatal complex, due to its high quality bone definition, thin slicing, multi planar cross-sectioning and low patient dosage.

“…Traditional CT imaging may be as an axial, antero-posterior or coronal planes [39]. More recent, cone-beam computed tomography became used for maxillofacial imaging as it has many advantages over traditional CT, including higher image resolution, lower radiation dose, offers 3-dimensional images and lower cost of machine [40,24]. Thus, the type of used CT imaging machine and the planes used to assess sinonasal condition may affect the frequency of the discovered www.acbjournal.org https://doi.org/10.5115/acb.20.247 CB cases specially in mild ones.…”

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%).

“…For Orhan et al (2017), due to their location, the sinuses cooperate to the development of facial structures, jaws, and upper airways; humidification and heat of inspired air; thermal insulation; increased voice resonance; cranial structure weight; and expansion of olfactory surfaces. Additionally, sensitive structures are insulated from the rapid fluctuations of temperature in the nose.…”

The characteristics of the paranasal sinuses (maxillary, frontal, sphenoid and ethmoid sinuses) are information of great relevance to Forensic Sciences, as their images can be used for human identification purposes. Due to their particularities, the paranasal sinuses provide valuable information for human identification, reducing the risk of errors during investigation by experts. Such structures are visualized from several imaging exams. This study evaluates the possibilities of human identification through the analysis of the paranasal sinuses, as well as the effectiveness of their analysis in estimating sex, age and ancestry. A comprehensive search was performed in the PubMed, SciELO, LILACS, and Web of Science databases. As inclusion criteria, texts that addressed the subject were selected. Imaging analysis of the frontal, maxillary and sphenoid sinuses is a useful tool for human identification, as well as for estimating sex, age and ancestry; usually provides a high level of accuracy. Regarding the ethmoid sinus, research is indicated to verify its use in human identification, as no publications on this specific subject were found. Additional research must be carried out (especially three-dimensional analysis of the paranasal sinuses), to develop standardized protocols, improving the work of experts, helping justice and society.
