“…Our results also indicate that the affected sinus volume in the ISSD patients is typically larger than previously reported values in healthy subjects, with the median value of 6.8 cm 3 , compared to previous reports of 3.4 cm 3 in Asian [32] and 4.0 cm 3 in Caucasian [33] populations, as well as results of more local studies reporting 5.3 cm 3 in German [34] and 3.5 cm 3 in Spanish [35] populations. So far, possible reasons for the development of isolated sphenoiditis have not been fully determined.…”

Intraoperative Sphenoid Sinus Volume Measurement as an Alternative Technique to Intraoperative Computer Tomography

et al. 2020

Isolated sphenoid sinus disease (ISSD) is where there is a group of pathologies characterized by inflammation in one or both sphenoid sinuses. Although computer tomography (CT)-based 3D reconstruction remains the gold standard among noninvasive approaches to ISSD diagnostics, no standardized techniques for direct intraoperative measurements of the sphenoid sinus volume in ISSD patients have been documented. We suggest a novel technique for the intraoperative measurement of the sphenoid sinus volume. Our technique is based on filling the sinus with 0.01% methylene blue solution after an endoscopic endonasal sphenoidotomy. The proposed technique was applied to 40 ISSD patients during surgery. Obtained intraoperative measurements were compared to noninvasive measurements from 3D reconstructions based on preoperative CT scans. Our results demonstrated that the obtained measurements did not exhibit significant differences exceeding 0.4 cm3, with CT-scan-based measurements in 39 out of 40 cases (p < 10−6, Wilcoxon sign-rank nonparametric test), thus confirming the accuracy of the proposed technique. Disagreements between direct intraoperative and CT-based measurements in a single case have been attributed to the presence of remaining pathological masses in the sinus, which was further confirmed during the secondary check of the operated sinus. Accordingly, we suggest that the agreement between the CT-based and intraoperative volume measurements can be used as an indicator of the successful elimination of all pathological masses from the sinus without having to perform an adequate exposure of the entire sphenoid sinus to reduce intraoperative bleeding. The proposed technique is accurate and does not require the involvement of specialized intraoperative CT scanners and avoids additional radiation exposure for the patient during an additional postoperation CT scan to confirm the success of the surgery.

“…Importantly, our database was composed of relatively young patients (mean age, 28.4 ± 5.2 years). Some studies have reported an age-related reduction of volume [ 6 , 18 , 19 ]. Our volumetric findings for the MS within the same age range are similar to the results that were reported by Jun et al .…”

“…The size and shape of the MS has been investigated in many previous studies [ 1 ]. The literature shows the influence of breathing patterns [ 4 , 15 ], dental problems [ 7 , 16 ], anatomical features [ 2 , 16 , 17 ], gender [ 1 , 2 , 18 ], age [ 18 , 19 ], ethnicity [ 20 , 21 ], and climatic factors [ 22 , 23 ] on MS volume. Furthermore, many chronological and pathological events can affect MS volume.…”

Computed tomography-based volumetric tool for standardized measurement of the maxillary sinus

et al. 2018

Volume measurements of maxillary sinus may be useful to identify diseases affecting paranasal sinuses. However, literature shows a lack of consensus in studies measuring the volume. This may be attributable to different computed tomography data acquisition techniques, segmentation methods, focuses of investigation, among other reasons. Furthermore, methods for volumetrically quantifying the maxillary sinus are commonly manual or semiautomated, which require substantial user expertise and are time-consuming. The purpose of the present study was to develop an automated tool for quantifying the total and air-free volume of the maxillary sinus based on computed tomography images. The quantification tool seeks to standardize maxillary sinus volume measurements, thus allowing better comparisons and determinations of factors that influence maxillary sinus size. The automated tool utilized image processing techniques (watershed, threshold, and morphological operators). The maxillary sinus volume was quantified in 30 patients. To evaluate the accuracy of the automated tool, the results were compared with manual segmentation that was performed by an experienced radiologist using a standard procedure. The mean percent differences between the automated and manual methods were 7.19% ± 5.83% and 6.93% ± 4.29% for total and air-free maxillary sinus volume, respectively. Linear regression and Bland-Altman statistics showed good agreement and low dispersion between both methods. The present automated tool for maxillary sinus volume assessment was rapid, reliable, robust, accurate, and reproducible and may be applied in clinical practice. The tool may be used to standardize measurements of maxillary volume. Such standardization is extremely important for allowing comparisons between studies, providing a better understanding of the role of the maxillary sinus, and determining the factors that influence maxillary sinus size under normal and pathological conditions.

ZusammenfassungCMF-Traumen im Alter 65+ sind durch besondere Merkmale gekennzeichnet: Lokalisation und Frakturmuster, Stand des Involutionsprozesses mit Abnahme von Knochenquantität und -qualität, Begleitverletzungen, altersassoziierte physische und psychische Funktionseinbußen und präexistente Komorbiditäten. Der Stand des Wissens und aktuelle bevölkerungsbezogene Daten dieser Variablen werden zu Anfang dieser Übersicht dargestellt. Vor diesem Hintergrund wird dann zu den verschiedenen Frakturen und Frakturtypen in den einzelnen Regionen des Gesichtsschädelskeletts Stellung genommen und die Indikation zu einem konservativen oder operativen Prozedere in den Alterspopulationen diskutiert. Spezielle Aufmerksamkeit kommt dabei Fraktursituationen bei Zahnlosigkeit und Atrophie im Ober- und/oder Unterkiefer zu. Innerhalb des weitgesteckten Gesamtspektrums der Frakturszenarien haben schonende, situationsadaptierte, ggf. auch unkonventinelle Lösungen Priorität vor Standardtherapieverfahren. Neue Techniken wie computerassistierte Chirurgie und patientenspezifische Implantate spielen eine immer größere Rolle und werden an Einzelbeispielen demonstriert. Betont werden muss, dass die physischen Reserven und nötigenfalls die geriatrietypische Multimorbidität jedes Patienten individuell einzuschätzen ist und vorrangige Bedeutung vor dem kalendarischen Lebensalter hat.
