“…The average volume of the SS at the ages of 5 years and 15 years were 1.52 ± 1.60 cm 3 and 11.83 ± 3.48 cm 3 for males and 1.25 ± 1.37 cm 3 and 5.92 ± 3.89 cm 3 for females, respectively. The average volume of the SS at the age of 15 years was nearly consistent with the adult measurements, as reported in previous studies [ 12 , 15 ]. Most previous studies measured the size and volume of the SS in cross-sectional samples [ 12 , 15 ].…”

Background: The sphenoid sinus (SS) is located close to vital structures, such as the pituitary gland, and it has significant clinical relevance. This study aimed to clarify the growth pattern of the SS in Japanese children using three-dimensional computed tomography (CT). Methods: Seventy-eight participants with congenital, acquired, or external auditory canal cholesteatoma were recruited and underwent CT more than twice during their treatment. Using the volume-rendered images, the size and volume of the SS were measured. Furthermore, on the scout image, the morphological measurements of the cranial base were determined. Results: The size and volume of the SS increased with age, and peaked at the mean age of 15 years. For males, the volume of the SS was smaller than that of females aged <5 years. The growth rate of the SS was significantly higher in males than in females. The maximum growth rate was detected at the age of 12 years for males and 10 years for females. For females, the increase in the length of the anterior cranial base ceased at approximately 10 years of age and remained constant thereafter. In contrast, for males, the length of the anterior cranial base increased gradually until 15 years of age. Conclusions: Considering the similarity of the periods between the adolescent growth spurt and the maximum growth rate of the SS, changes in the size of the SS may be used as an indicator of the physical growth spurt.

“…The present study demonstrated that the results of SAS were not accurate for complex structures and for the boundary between air and the thin bone in the nasal cavity. Lentzen et al reported that the sphenoid sinus volume could be measured accurately and conveniently using SAS with MS correction, which was similar to the SSMA method proposed in this study ( 27 , 28 ). However, the procedure used for SSMA was simpler compared to the other reported methods; SSMA was found to be highly practical, efficient, and accurate in the present study.…”

ObjectiveEndoscopic endonasal surgery (EES) for deep intracranial lesions has gained popularity following recent developments in endoscopic technology. The operability of invasive pituitary neuroendocrine tumors (PitNETs) depends on the anatomy of the nasal cavity and paranasal sinus. This study aimed to establish a simple volume reconstruction algorithm of the nasal cavity and paranasal sinus. Additionally, this is the first study to demonstrate the relationship between the segmentation method and the clinical significance in patients with PitNET.MethodsPre-and postoperative tumor volumes were analyzed in 106 patients with primary (new-onset) PitNETs (80 nonfunctioning and 26 functioning) who underwent EES. The efficiency and accuracy of the semiautomatic segmentation with manual adjustments (SSMA) method was compared with other established segmentation methods for volumetric analysis in the nasal cavity and paranasal sinuses. Correlations between the measured nasal cavity and paranasal sinus volumes and the extent of tumor removal were evaluated.ResultsThe SSMA method yielded accurate and time-saving results following the volumetric analyses of nasal cavity and paranasal sinuses with complex structures. Alternatively, the manual and semiautomatic segmentation methods proved time-consuming and inaccurate, respectively. The sphenoid sinus volume measured by SSMA was significantly correlated with the extent of tumor removal in patients with nonfunctioning Knosp grade 3 and 4 PitNET (r = 0.318; p = 0.015).ConclusionThe volume of sphenoid sinus potentially could predict the extent of resection due to better visualization of the tumor for PitNETs with CS invasion.

“…[2][3][4] A deep anatomic knowledge of SS and sella turcica (ST) is therefore essential to improve the outcome of endoscopic transsphenoidal surgeries. In the last decades the number of anatomic and morphologic research on SS has progressively increased [5][6][7][8] due to the growing application of the transnasal transsphenoidal procedures as a mean for treatment of skull base lesions. For instance, a lot of interest has recently been laid on the metric characteristics of the ST, whose morphology and dimension can be influenced by many factors, such as sex, ethnicity, and age.…”

Introduction: Transsphenoidal surgeries imply the risk of intraoperative lesions to the neurovascular structures surrounding the sphenoid sinus (SS). Aim of the present study is to assess the metrical and morphologic relationships existing between SS and sella turcica (ST). Materials and Methods: Two hundred computed tomographyscans of patients were selected. For each patient volumes of SS were calculated from their 3-dimensional models segmented through ITK-SNAP program. Variants of SS in pneumatisation and sellar diameters [antero-posterior (AP) diameter, depth, and length] were evaluated on each computed tomography-scan. Correlations among different measurements were assessed through Spearman test (P < 0.01), whereas associations between sellar parameters and presence of pneumatisation variants were assessed through Mann-Whitney test (P < 0.01). Results: In males, pneumatization of the greater wings was related to smaller AP diameter (P < 0.01) and depth of ST (P < 0.01), whereas in females lower values of depth were found in patients with pneumatization of the pterygoid processes (P < 0.01). In both sexes, a positive correlation was found between AP diameter and, respectively, length and depth of ST (P < 0.01), together with a negative correlation between volume of SS and depth of ST (P < 0.01). Lastly, in females a positive correlation was found between age and, respectively, length and depth of ST (P < 0.01). Conclusions: The present study highlighted new metrical and morphologic relationships between volume and pneumatisation of SS and diameters of ST. Knowledge of these correlations allows to understand more clearly, in the preoperative setting, the surgical working space. Further studies are needed, especially for what concerns the relationship between sellar measurements and age in females.
