Abstract:Purpose
To determine the prevalence of concha bullosa (CB) and nasal septal deviation (NSD) and their impact on maxillary sinus volume (MSV).
Materials and Methods
Cone-beam computed tomographic (CBCT) images of 106 Emirati people were used in this study. The direction and angle of septal deviation were calculated. The presence of CB, which could be unilateral, contralateral, or bilateral in relation to the direction of NSD, was also recorded. MSV was measured using rec… Show more
“…Although turbinate hypertrophy is transient, the presence of NSD makes the hypertrophy persistent [ 14 ]. NSD is a common problem in the middle eastern population [ 11 ]. Computed Tomography (CT) is currently being used to study NSD and associated sino-nasal conditions [ 15 ].…”

“…Based on the angle of deviation, the NSDs were classified into mild (less than 9°), moderate (9°-15°), and severe (greater than 15°). This classification was according to the criteria followed by Al-Rawi et al [ 11 ]. Fig.…”
Background
In individuals with nasal septal deviation (NSD), compensatory hypertrophy of the nasal turbinates occurs as a protective mechanism of the nasal passage from dry and cold air. NSD associated nasal turbinate hypertrophy is usually recurrent, requiring repetitive imaging. Therefore, a multiplanar imaging modality with a low radiation dose is best suited for long-term follow-up of this condition. This study aimed to evaluate the association of width of inferior turbinates and presence of concha bullosa with the degree of NSD using Cone beam computed tomography (CT).
Methods
The CBCT scans of 100 patients with NSD were selected as per convenience sampling and were evaluated by two maxillofacial radiologists. The width of the non-hypertrophied inferior turbinate (NHT) on the convex side of the NSD, and hypertrophic inferior turbinates (HT) on the concave side of the NSD were measured at three locations. The septal deviation angle (SDA) and the presence of concha bullosa (CB) were determined.
Results
A significant difference was observed in the anterior, middle, posterior, and mean widths between HT and NHT (p < 0.001). There was a significant difference in the widths of the HT and NHT among different types of NSD. A strong positive correlation (r = 0.71, p < 0.001) was found between SDA and the mean width of the HT. Age (P = 0.71) and gender (P = 0.65) had no significant difference among different types of NSD. Regression analysis revealed that the presence of CB (p = 0.01) and middle width of the HT (p < 0.001) are significant predictors of SDA and type of NSD.
Conclusion
The results of the present study reveal that the middle width of the HT and the presence of CB influence the degree of NSD. The present study results recommend the use of CBCT as a substitutive low radiation dose imaging modality for evaluation of NSD, CB, and associated inferior turbinate hypertrophy.

“…The presence of a concha bullosa is thought to cause crowding in the middle meatus region, thereby impeding the ventilation and respiratory flow through the meatus. 15 The association of nasal septal deviation with concha bullosa has been extensively studied. It has been observed that a unilateral concha bullosa or the dominant one in bilateral concha bullosa is associated with contralateral deviation of nasal septum.…”

“…Есть другое мнение, что только умеренное отклонение ДНП влияет на объем ВЧП [27]. Исследования, включающие суммарно 869 обследуемых, показали, что на стороне выраженной деформации перегородки носа объем ВЧП был меньше, чем на контралатеральной стороне [28][29][30][31], где зачастую имелась СВ. При двусторонней СВ наблюдалось увеличение ВЧП с обеих сторон [2].…”
The structure of the paranasal sinuses (PNS) is characterized by pronounced variability and largely depends on the state of the intranasal architectonics, the violation of which may be a predisposing factor for the development of sinusitis. Leading among the disturbances in the architectonics of the nasal cavity and nasopharynx are the nasal septum deviation (NSD), concha bullosa (CB), hypertrophy of the inferior turbinates and pharyngeal tonsil. This review presents an analysis of modern data on the influence of the architectonics of the nasal cavity and nasopharynx on the development of PNS and the formation of inflammatory processes in them. Sources of information - databases Medline, Pubmed, Cochrane, E-library from 2004 to 2019. The search was carried out by keywords. Criteria for inclusion of articles in the review: assessment of multispiral computed tomography of SNP of patients in axial and coronary projections, presence of a control group, sample size of more than 50 people. In the presented review, it is noted that types 3 and 5 of DNP according to the classification of R. Mladina, along with contralateral CB and adenoids, can be predictors of the development of sinusitis. Information about the side of sinusitis formation in relation to the direction of the deformity of the nasal septum, about the effect of other violations of the architectonics of the nasal cavity on sinusitis and the size of the SNP remains controversial. The reasons for the contradictions are the use of different classifications of DNP, the underestimation of the complexes of anatomical anomalies and the mechanisms of aerodynamics of the sinuses, which determine the greater dependence of the volume and ventilation of the sinuses on expiration than on inspiration. Taking these positions into account, the question of the influence of the architectonics of the nasal cavity on the development of the paranasal sinuses and the formation of the inflammatory process in them requires further study.
