background and aim . vertical and horizontal bone resorption of the alveolar ridge are common in edentulous jaws. in the distal area of the maxilla, an adequate bone volume is often lacking because of the proximity of the sinus cavities to crestal bone. sinus floor augmentation is an established way of increasing the height and volume of bone in the posterior region of the maxilla, which increa...

OBJECTIVE This study aims to evaluate the usefulness of the CompuDent program in determining the pre-operative volume of bone graft in maxillary sinus floor lifts, and to calculate the volume of graft necessary for rehabilitation using varying lengths of implants. STUDY DESIGN Based on the CompuDent program, we calculated the volume of graft necessary for 47 sinus lifts. This volume was measu...

This study is aimed at assessing the reliability of morphometric measurements performed on the frontal sinus, nasal septum and maxillary sinus in personal identification using three dimensional Cone Beam Computed Tomography. This study propounds the significance of combined use of all three particularly maxillary sinus and nasal septum pattern in individual identification. This retrospective st...

In the field of forensic medicine, normally the available materials after sufficiently long period of death will be utilized to determine various body characteristics such as age sex etc for identification of individual.Identification of corpses is a difficult forensic procedure and it is mandated by laws and social rules. Comparison of ante mortem and post mortem medical records, such as denta...

Pneumatization of maxillary sinus causes insufficient vertical bone volume on posterior maxilla. So the restoration of edentulous posterior maxilla with dental implants is challenging due to a deficient posterior alveolar ridge, unfavorable bone quality and increased pneumatization of the maxillary sinus.1 For maxillary sinus augmentation, the crestal approach and the lateral window approach ha...

The objective of the study was to estimate the normal upper and lower limit cut-off value of the different dimensions of maxillary and frontal sinuses, and also to determine the influence of gender on the obtained variables and to observe the effect of nasal septal deviation on maxillary sinus. The observational study was carried out and a total of 60 samples were collected from both males and ...

Background: To compare the maxillary sinus (MS) volumes of the patients’ with and without posterior crossbite (PCB). Method: The CBCT scans of 2 groups were studied: (1) 50 patients (mean age: 14.39±1.32 years)without posterior crossbite (NCB); (2) 24 patients (mean age: 14.15±1.53 years) with PCB. After the volume calculation with using Dolphin 11.0 (Dolphin Imaging, Chatsworth, Calif, USA) so...

BACKGROUND AND PURPOSE The size of the primary lesion and the lymph node metastasis are critical indicators for the patient prognosis. Here we attempted to assess the correlation between these 2 prognostic parameters in patients with oropharyngeal, hypopharyngeal, oral, or maxillary sinus cancer. METHODS We retrospectively studied 66 patients with oropharyngeal or hypopharyngeal (n = 24), ora...

Macaques (genus Macaca) are unique among cercopithecids in that they possess a maxillary sinus, and among anthropoids in that they demonstrate a relatively weak relationship between the size of this sinus and the cranium. To test the hypothesis that extrinsic factors may contribute to maxillary sinus size variation, a sample of 46 Japanese macaque (M. fuscata) crania from known localities were ...

PURPOSE The aim of this study was to investigate the initial effects of maxillary expansion therapy with Hyrax appliance and to evaluate the related changes in maxillary sinus volume. MATERIALS AND METHODS Thirty patients (20 females, 10 males; 13.8 years) requiring maxillary expansion therapy, as part of their comprehensive orthodontic treatment, were examined. Each patient had cone-beam com...
