The present study showed the volume software to be a suitable tool for the measurement of the dimensions of the maxillary sinus. The results show that the osseus volume of the maxillary sinus varies on the base of gender and that the obliterated volume varies on the base of a present pathology. No statistically significant association between the patient’s age and the sinus volume or a present s...
Velasco-Torres et al. [19] showed a larger sinus volume for dentate patients compared to edentulous and partially edentulous patients. This may be explained through the loss of posterior teeth in the maxilla, leading to the reduction of mechanical stimulation of the maxillary sinus. As a consequence, the sinus could expand (pneumatization) due to increased pressure and ostoclastic activity of the ...
The aim of this study was to analyze volume parameters of the maxillary sinus based on CBCT data. Further, neighboring anatomical structures and related pathologies were recorded. Overall, the applied volume software used in this study allowed the calculation of the surface area and volume of maxillary sinuses.
In clinics, the radiographic evaluation of the maxillary sinus is obligatory prior to ...
No relationship was observed between a patient’s age and the presence of partial or complete obliteration of at least one maxillary sinus (Fig. 6, p = 0.92). Patient’s age and the mean osseus sinus volume were also not associated significantly (Fig. 7, p = 0.20). Both maxillary sinuses (osseus borders) of each patient were quite similar in size (mean difference between left and right...
In total, 128 maxillary sinuses were analyzed. The mean surface area was found to be 39.7 cm2 and the mean volume 17.1 cm3. The mean surface area of the remaining pneumatized cavities of obliterated sinuses was found to be 36.4 cm2 and the mean volume 15 cm3 (Table 1). 42.2% of all sinuses showed an obliteration, and the mean volume of the obliterated sinuses was 5.1 cm3. If there was an obl...
Patient-specific variables like gender, date of birth, and date of CBCT were recorded. The date of the CBCT image was further divided into either being in autumn/winter (1 January 2013–19 March 2013; 22 September 2013–31 December 2013) or spring/summer (20 March 2013–21 September 2013). The maxillary sinus was classified into obliterated or nonobliterated. It was also documented if there was...
In the present study, 64 CBCT images (128 maxillary sinuses), taken between 1 January 2013 and 31 December 2013 at the Department of Cranio-Maxillofacial and Oral Surgery at the University of Zurich, were included. The inclusion criterion of each CBCT scan was the presence of two complete maxillary sinuses; the osseus borders of both sinuses had to be entirely visible.
The scans were performed us...
The precise assessment of the maxillary sinus is important in oral and maxillofacial surgery in cases of traumatology, sinusitis, and dental implantology. After the introduction of cone-beam computed tomography (CBCT) in dental medicine in 1998 [1], the number of clinicians using CBCTs increased constantly. Whereas in 2004, there were only three CBCTs registered in Switzerland, the current number ...
There are few studies measuring the dimensions of the maxillary sinus, being mostly based on computed tomography imaging and rarely being based on cone-beam computed tomography (CBCT). The aim of this study was to measure the 3D osseous and soft tissue defined volume and surface area of the maxillary sinus. Further, possible associations with patient-specific and sinus-related variables were evalu...
