“…The mean volumes of structures measured in mentioned studies are given in Table 5 as a comparison of literature. Similarly as Emirzeoglu et al 6 and Ertekin et al, 7 we reported that a significant difference between male and female subjects in the NC measurements. We detected, as in these 2 studies, that the males' NC volumes and other structures' volumes in NC were greater than those in females.…”

“…This study is a reference study in Turkish population, where wide-scale volumetric calculations are made using stereological method. Also, the volume of the nasal septum was evaluated in this study, unlike in the study conducted by Emirzeoğlu et al 6 Ertekin et al 7 and Emirzeoğlu et al 6 used CT images with a cross-sectional thickness of 0.6 mm and 3 mm, respectively. Unlike these 2 studies, we examined a 0.4 mm slice of thickness on CBCT images.…”

“…There is only 1 study that shows the proportion of concha volumes in the whole NC volume. According to the study by Ertekin et al, 7 the volume proportion of inferior nasal concha is in the range of 9-15% of the total volume of the NC. In the same study, the middle nasal concha volume proportion was reported in a range between 19-31% of the total volume of the NC.…”

“…In literature, only 2 studies evaluated the volumetric changes of the NC using the stereological method on CT images. 6,7 Also, these studies researched the changes in structures visible on CT images. In this study, we used CBCT images, where the resolution is better than the resolution of CT images.…”

“…Emirzeoğlu et al 6 worked on individuals who were 18-40 years old. Ertekin et al 7 studied children 8-11 years of age. We conducted this study on a wide range of age groups (8-59 years of age), including the age range of both mentioned studies.…”

Background. The nasal cavity (NC) is the entrance to the respiratory system. Many studies have been conducted on the structure, function and volume of the NC. Only a few studies were performed assessing the volumetric values of NC and conchae. Objectives. The aim of this study was to evaluate the volumetric measurements of the NC, conchae and nasal septum using the stereological method. Material and methods. Cone-beam computed tomography (CBCT) images of 200 individuals (100 females and 100 males) aged 8-59 years were retrospectively evaluated. Inferior nasal concha and middle nasal concha, NC and nasal septum volumes were measured on these images. Measurements were made using point counting method, which is based on the Cavalieri principle. The mean values of the measured structures for 2 age groups and for each gender were obtained. Differences between the groups and genders of all parameters were examined. The volume fractions of measured volumes were calculated. Results. The mean volumes of the nasal septum, left and right NC, left and right inferior nasal conchae, and left and right middle nasal conchae were 4.99 ±1.51 cm³, 7.44 ±2.93 cm³, 7.68 ±2.99 cm³, 3. 10 ±1. 11 cm³, 3.04 ±1.02 cm³, 1.32 ±0.56 cm³, and 1.28 ±0.49 cm³, respectively. Gender and age differences were statistically significant in all volumes (p < 0.05). Conclusions. The data obtained in this study may assist clinicians in planning treatment, assessing the treatment results of pathological conditions within the NC, and help surgeons in preoperational and postoperational evaluations, especially in dentistry, otorhinolaryngology and plastic surgery.
