“…This is similar to various literatures in the past. Narendra kumar and Subramaniam 9 who Presented it as 76% whereas Turnaet al 10 The strengths of the study are along with a study of incidence of various individual anatomical variants, detailed knowledge was gained about concomitant existence of two or more variations in the same patient. Limitations being, since it included only those people who presented to the ENT OPD with complaints regarding nose and paranasal sinuses, there might be a bias in extending the results to the general population.…”

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.

“…Turna et al (39) has found that the most prevalent pneumatized concha was the middle concha (57.2%) with the least prevalent inferior concha by 1%. Aramani et al (40) reviewed 54 CT scans and found that the concha bullosa were present in 53.7%…”

Objectives: The paranasal sinuses include anatomic structures at the maxillofacial region that matters great importance for the surgeons working in the maxillofacial area. The imaging of anatomic variations of the paranasal sinuses is fundamental to evaluate the predisposing factors for the pathologic changes of paranasal sinuses. The aim of this study is to investigate the prevalence of anatomic variations of the paranasal sinuses by retrospective assessment of cone beam computed tomography (CBCT) images. Methods: The paranasal sinus CBCT images of 300 adult patients who were referred to Marmara University, Faculty of Dentistry, Department of Oral Diagnosis and Radiology were evaluated retrospectively. The paranasal sinus variations and their prevalence were recorded. Results: The prevalence of concha bullosa superior was 7,7%, and concha bullosa media was 54,7%. The prevalence of infraorbital ethmoid cell was 15,3%, agger nasi cell was 52,7% and onodi cell was 52.7%. There was no significant differences prevalence of this anatomic variations between males and females or between different age groups. Conclusions: CBCT is a convenient radiographic examination to evaluate the paranasal sinus anatomic variations. Dental surgeons must be aware of such anatomic variations of the paranasal sinuses.

“…Nasal septum deviation is the most common physical disorder regarding the nasal septum. The origin of the deviation has been described as either developmental (usually smooth, “C-shaped” or “S-shaped” nasal septum with occurrence more often in the anterior septum) or traumatic (usually irregular, angulated, and sometimes dislocated) [ 10 , 12 ]. It may be cartilaginous, osseocartilaginous or osseous [ 11 ].…”

“…It may be cartilaginous, osseocartilaginous or osseous [ 11 ]. Septal deviation can displace the middle turbinate, narrowing the middle meatus, making surgical access difficult and causing obstruction of the normal mucous flow and, consequently, secondary inflammation and infection [ 10 , 17 ]. The reported prevalence of septal variations in the literature ranges between 26% and 97% due to varying morphological features and the extent of deviation [ 14 ].…”

The anatomy of the nasal cavities and paranasal sinuses is one of the most varied in the human body. The aim of this study is to review the prevalence of anatomical variations in the sinonasal area. This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We performed on PubMed a literature search from October 2004 until May 2020. The search strategy included the following keywords: (‘paranasal sinus’ OR ‘frontal sinus’ OR ‘maxillary sinus’ AND (‘anatomical variants’ OR ‘anomalies’)). Fifty studies were eligible and included in the analysis. Overall, the studies encompassed a total of 18,118 patients included in this review. Most common anatomical variations include agger nasi cells, nasal septum deviation and concha bullosa. Other variations seen in this region are uncinate process variations, paradoxical middle turbinate, Haller, Onodi and supraorbital ethmoid cells, accessory ostia of maxillary sinus. Less common variations include any sinus aplasia, crista galli pneumatization and dehiscence of the optic or maxillary nerve, internal carotid artery and lamina papyracea. Anatomical variations of this region also differ among ethnic groups. This study highlights the amount, variability and significance of most anatomical variants reported in the literature in the last years. It is essential for the sinus surgeon to have a broad spectrum of knowledge not only of “the typical” anatomy but also all the possible anatomical variations. With modern imaging modalities, anatomical variations can be detected, and uneventful pitfalls might be prevented.
