Abstract

<abstract> <title> <x xml:space="preserve">Abstract</x> </title> <sec> <title>Abstract</title> <p>Aim of this investigation is to evaluate prevalence, localization, and height of 114 maxillary sinus septa by using cone-beam computed tomography scans. The thickness of the mucosa has been measured together with the variations of the membrane in relation to those septa.</p> <p>A total of 228 maxillary sinuses have been considered. Septa were identified using "panorex" reconstructions and axial scans of cone-beam computed tomography using the software "eXamVision." The thickness of the mucosa has been evaluated in the paraxial scans and related to those septa where they were present.</p> <p>In the current study, the prevalence of sinus septa is 38.1%. Significant difference can be found in the height of primary and secondary septa. The mean height of primary septa was 5.5 mm (±1.19) and of secondary septa 3.4 mm (±1.6). Anterior and medium septa resulted significantly higher than posterior septa (<italic>P</italic> = 0.003). The medium thickness of the mucosa was 0.85 mm (±0.58), whereas close to the septa it turned out to be 1.8 mm (±1.87). The difference is statistically relevant (<italic>P</italic> = 0.003). There is no statistically significant proportional relation between dimensions of septa and thickness of mucosa (<italic>P</italic> = 0.53).</p> <p>Underwood septa are frequent anatomic variations of the maxillary sinus. Their presence may result in a thickening of the sinus membrane. The systematic study of radiographic anatomy of maxillary sinus is necessary before the sinus lift surgery planning.</p> </sec> </abstract>
