“…Since the SS is critical in the surgical treatment of the pituitary gland and can provide access to other parts of the skull base, the evaluation of volume is also important for patients with variant craniofacial morphology. [23] The SS volume is one of the most relevant parameters for planning a surgical intervention, and few population studies have been published over time. [24] In this study, the IFCSS and ICSSwP patients were included to attain a certain amount of data.…”

Objectives: In this study, we aimed to investigate the association of sphenoid volume and pneumatization type with pathologies, including unilateral isolated chronic sphenoid sinusitis with polyps (ICSSwP) and isolated fungal chronic sphenoid sinusitis (IFCSS). Patients and Methods: A total of 26 patients (15 males, 11 females; mean age 49.9±15.0 years; range, 18 to 80 years) with unilateral isolated sphenoid inflammation, pathologically diagnosed as IFCSS (n=14) or ICSSwP (n=12) between January 2010 and December 2018 were included in this study. The sphenoid sinus volumes of the pathological and normal sides of the patients were compared. The sphenoid pneumatization types were also evaluated. Results: In the IFCSS group, the pathological side volume was statistically significantly higher than the healthy side volume (p<0.05). In the ICSSwP group, the pathological side volume was statistically significantly lower than the healthy side volume (p<0.05). Conclusion: Large sphenoid sinus volume is prone to IFCSS, while smaller sphenoid sinus volume is prone to ICSSwP. Therefore, it should be considered that difference in the right and left sphenoid sinus volume may have different etiological or predisposing effects for different pathologies.

“…The volume of the coronoid and condylar process of the mandible was assessed through CBCT (Picasso Trio 3D, 85 kVp, 5 mA, voxel of 0.2 mm and a 12 × 8.5 cm FOV; Vatech, Hwaseong, South Korea). For this, CBCT multiplanar reconstructions were assessed with the semi-automatic mode of ITK-SNAP 3.4.0 segmentation software (Cognitica, Philadelphia, PA, USA) [ 38 ]. After segmentation, bone volumes were measured in cubic millimeters.…”

This study assessed the safety and efficacy of three different doses of BoNT-A for persistent myofascial pain (MFP). One hundred female subjects were randomly assigned into five groups (n = 20): oral appliance (OA), saline solution (SS) and three BoNT-A groups with different doses. Pain intensity and pressure pain threshold were evaluated up to 24 weeks after treatment. Adverse effects related to muscle contraction, masticatory performance, muscle thickness and mandibular bone volume were also assessed. Changes over time were compared within and between groups. The “nparLD” package and Wilcoxon signed-rank test were used to analyze the data. BoNT-A reduced pain intensity (p < 0.0001) and increased pressure pain threshold (p < 0.0001) for up to 24 weeks compared to the placebo. No differences were found between BoNT-A and OA at the last follow-up. A transient decline in masticatory performance (p < 0.05) and muscle contraction (p < 0.0001), and a decrease in muscle thickness (p < 0.05) and coronoid and condylar process bone volume (p < 0.05) were found as dose-related adverse effects of BoNT-A. Regardless of the dose, BoNT-A was as effective as OA on MFP. Notwithstanding, due to BoNT-A dose-related adverse effects, we suggest the use of low doses of BoNT-A in MFP patients that do not benefit from conservative treatments.

“…Nejaim et al., segmenting the SSs on 172 CBCTs, observed no influence of skeletal classes (class I, II, III), facial types (brachycephalic, mesocephalic, dolichocephalic), sex and intrasinus septa on sinuses volumes, and no significant difference between the volumes of the right and left SS; 16 the last evidence was also found by Cohen et al. 17 Oliveira et al., instead, found a significant difference between the right and the left side, with the greatest volume of the right post-sellar sinus, when compared with pre-sellar and sellar types.…”

Segmentation procedures for the assessment of paranasal sinuses volumes

et al. 2020

View full text Add to dashboard Cite

Background The paranasal sinuses are complex anatomical structures, characterised by highly variable shape, morphology and size. With the introduction of multidetector scanners and the development of many post-processing possibilities, computed tomography became the gold standard technique to image the paranasal sinuses. Segmentation allows the extraction of metrical and shape data of these anatomical components that can be applied for diagnostic, education, surgical planning and simulation, and to plan minimally invasive interventions in otorhinolaryngology and neurosurgery. Discussion Our aim was to provide a review of the existing literature on segmentation, its types and application, and the data obtained from this procedure. The literature search was conducted on PubMed (including Medline), ScienceDirect and Google Scholar databases, using the keywords as follows: ‘paranasal sinuses’, ‘frontal sinus’, ‘maxillary sinus’, ‘sphenoid sinus’, ‘ethmoid sinus’, in all possible combinations with the keywords ‘segmentation’ and ‘volumetric analysis’. Inclusion criteria were: articles written in English, on living human subjects, on the adult population and focused on paranasal sinuses analysis. Conclusion This article provides an overview of the types and main application of segmentation procedures on paranasal sinuses, and the results provided by the studies on this topic.
