The maxillary sinus (MS) is described as a pyramid-shaped cavity of the maxilla. Knowledge of its morphology makes it possible to define normality and abnormality so that its three-dimensional analysis can be a valuable preoperative tool during surgery in this anatomical area. The aim of this study is to present a strategy of morphological analysis of the MS using 3D printing acquired through computed cone beam tomography (CBCT) images. A cross-sectional descriptive study was conducted, including 15 subjects (8 women and 7 men). The 3D virtual reconstruction and modeling was done on the MSs bilaterally, and 30 physical models were produced on a 3D printer. The results revealed that the MSs obtained exhibited various morphologies. An individual analysis of... |

The development of the paranasal sinuses, in human race and in many mammals remained as much an enigma as it did nearly two millennia ago. Morphometric analysis of maxillary sinuses in human foetuses are not fully documented and also their morphological studies in Indian population are non-existent. So the present study was conducted to determine the different diameters, the pattern of growth, sexual dimorphism and bilateral variations in maxillary sinuses. 37 human foetuses of different age groups (16 - 34 wks of IUL) were divided into five groups on the basis of age. Maxillary sinuses were dissected out from the nasal aspects of maxillae and their various diameters were measured with the help of Vernier callipers. The percent growth of AP diameter was... |

The maxillary sinus varies according to age, however there are limited studies that have illustrated its 3D form over time. This study aimed to classify the maxillary sinus by the shape, number of septa and scallops in a 1 to 25 year age group, utilising computerized tomography (CT) scans and 3D reconstruction. CT scans (n=480) were reviewed from the picture archiving and communication system (PACS) of the state and private hospitals in Pietermaritzburg and Durban KwaZulu- Natal (KZN), South Africa. The sample consisted of 276 males and 204 females, 1-25 years and of two population groups, black African and white. SLICER 3D (www.slicer.org) was utilised in order to reconstruct a 3D model of the sinus. Morphological traits such as the presence of the sinus,... |
